Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a pre-broadcast detection system for programs broadcast in an IP format, which is used to detect a multi-channel pre-broadcast signal in a broadcasting system of a television station. The program pre-broadcasting detection system for IP broadcasting is particularly suitable for a broadcasting system of uncompressed IP audio and video signals.
The system may include: playout server 100, detection server 200 and user equipment 200. These three devices are further explained below, respectively.
Broadcasting server
The broadcast server 100 may be configured to pre-broadcast the target program to be broadcast on the target channel according to the program list of the target channel.
The target program may be at least one program to be broadcast in a program list of the target channel. The programs described herein are generally referred to as audiovisual forms of the programs.
The pre-broadcasting refers to broadcasting in advance relative to the program start time in the program list, for example, broadcasting the program start time in the program list of the target channel for a preset time length, where the preset time length is at least longer than the program broadcasting time length, for example, pre-broadcasting the audio and video corresponding to the program a, where the broadcasting time length of the program a is 1 hour, and the preset time length is at least longer than 1 hour in order to achieve the purpose of pre-broadcasting review and reserve processing time for finding a problem. Of course, the specific value thereof may be set according to actual requirements, and the embodiment of the present invention is not particularly limited thereto. Optionally, the broadcast server 100 may be further configured to determine a preset time length according to the broadcast time length of the target program in the program list; and determining the pre-broadcasting time of the target program according to the broadcasting starting time of the target program in the program list and the determined preset time.
Alternatively, the program guide of each channel may be stored in advance in the first database 104 of the playout server 100. As shown in fig. 1, when the broadcast server 100 has a need to acquire a program, the corresponding program may be acquired from the first database 104 through the program module 101, and then the acquired program may be transmitted to the broadcast control module 102. The broadcast control module 102 may obtain the program content to be played according to the received program list, so that the broadcast server 100 may pre-broadcast the program content to be played.
Optionally, at least one broadcasting server 100 may be deployed in the system for detecting a program broadcast before IP-oriented broadcasting, and each broadcasting server 100 may support output of high-definition uncompressed audio and video signals of 4 to 6 channels.
Detection server
The detection server 200 may be configured to obtain the audio and video of the target program that is pre-broadcast from the broadcast server 100, and detect the audio and video according to a preset detection rule to generate a detection result.
Alternatively, as shown in fig. 1, the detection server 200 may pull the audio and video stream of the pre-broadcast target program from the broadcast server 100; then, the signal acquisition module 201 acquires audio and video signals; then, the analysis and detection module 202 analyzes and detects the acquired audio and video signals; the discovered faults are then filtered and alarmed by the fault filtering and alarming module 203. Some faults are allowable, such as a black field fault appears in a video, but the duration of each black field is not more than 0.5 second, and the number of times of the black field is less than 2, the faults are allowable, and an alarm is not needed, so that fault filtering, convergence alarm and alarm overflow are also needed. Finally, the detection server 200 may automatically save the process log of the broadcast and the detection result to the second database 204 of the detection server 200.
Optionally, at least one detection server 200 may be deployed in the pre-broadcast detection system for programs broadcast over IP, and each detection server 200 supports real-time analysis and detection of 1 to 16 channels of high-definition uncompressed audio/video signals.
User equipment
The user device 200 may be configured to obtain the detection result from the detection server 200 and display the detection result for review by an auditor.
Alternatively, the user device 200 may be a terminal device such as a mobile phone, a tablet computer, a desktop computer, or the like. The user equipment 200 may install client software, and the current playing state and the detection result of the pre-played target program may be automatically refreshed in real time or at regular time through the client software.
It should be noted that, in the embodiment of the present invention, the audio and video corresponding to the target program may be transmitted in the form of an IP signal in the pre-broadcast detection system of the program for IP-oriented broadcasting.
The system for detecting the program to be broadcasted before broadcasting, which is provided by the embodiment of the invention, can acquire the program to be broadcasted and pre-broadcast the program through the broadcasting server 100 so as to realize the detection of the program before broadcasting; the detection server 200 can analyze and detect the program pre-played by the broadcast server 100 according to the preset detection rule to obtain the detection result, so that the automatic detection of the program can be realized, the manual examination and verification operation is omitted, the detection efficiency is improved, meanwhile, the occurrence of the missed detection condition can be reduced, and the program broadcasting safety is improved. The detection result can be displayed through the user equipment 200, so that auditors can check the detection result, and when broadcasting faults are found according to the detection result, measures can be timely taken in advance, and the probability of the broadcasting faults is reduced.
As an alternative embodiment, the target program may be an audio/video material to be played that is locally stored by the broadcast server 100, or an audio/video to be rebroadcast that is acquired by the broadcast server 100 from an external device.
In the embodiment of the present invention, the broadcast control module 102 in the broadcast server 100 may determine, according to the program information in the program list, whether the target program obtains a broadcast material from the audio/video material locally stored in the broadcast server 100 for playing, or obtains an audio/video to be rebroadcast from an external device for playing.
The foregoing two cases are explained separately below.
(1) The target program is an audio/video material to be played and locally stored by the playing server 100
In the embodiment of the present invention, for locally stored audio/video materials, the broadcast server 100 supports a decoding broadcast function, that is: the broadcasting server 100 can automatically perform pre-decoding broadcasting on the audio and video material to be broadcasted. The details are as follows:
as shown in fig. 1, a program module 101 in a broadcast server 100 may obtain a program of a target channel and material information corresponding to a program to be broadcast in the program from a first database 104; the broadcast control module 102 may obtain the audio/video material file to be played from the material storage module 105 according to the program list and the material information, generate a file decoding broadcast task, and then set the task execution time according to the start broadcast time of the target program in the program list. And the task execution time is earlier than the preset time length of the starting broadcast time of the target program in the program list.
The broadcast control module 102 may send a control instruction to the decoding module 103 according to the task execution time of the file decoding broadcast task by using an immediate control instruction, and the decoding module 103 may decode the acquired audio/video material file into a non-compressed audio/video signal according to the control instruction, so that the broadcast server 100 may broadcast a corresponding audio/video signal.
Wherein, the aforementioned material information may include: a material file name, a material file ID (i.e., a material file identification number), a material file type (e.g., an advertisement type, a television show type, an art type, etc.), a material file in-point (i.e., a start time of a material file), and a material file out-point (i.e., an end time of a material file), etc. The material files refer to audio and video material files.
(2) The target program is the audio/video to be rebroadcast acquired by the broadcasting server 100 from the external equipment
In the embodiment of the present invention, the broadcast server 100 supports the function of scheduling external audio and video and performing pre-rebroadcasting on the external audio and video according to a program list, which is specifically described as follows:
as shown in fig. 1, the system for detecting programs broadcasted in IP-oriented before broadcasting may further include: the scheduling server 400.
The broadcasting server 100 may be further configured to send a scheduling instruction to the scheduling server 400 in advance according to the program, the scheduling server 400 may be configured to obtain the audio and video to be rebroadcast of the target channel from the external device according to the scheduling instruction, and send the audio and video to be rebroadcast to the broadcasting server 100 for pre-broadcasting, so that the detection server 200 may obtain the pre-broadcasted audio and video to be rebroadcast from the broadcasting server 100, thereby implementing pre-broadcast detection on the external audio and video. Because the rebroadcast external audio and video is an application scene with more problems in the television broadcasting service, compared with the prior art that only audio and video materials stored in a local database are audited before broadcasting, the embodiment of the invention not only audits the audio and video materials stored in the local database before broadcasting, but also audits the external audio and video signals before broadcasting by automatically scheduling the external audio and video signals in advance, thereby increasing the checking means, leading the audition before broadcasting to be more comprehensive and improving the safety of program broadcasting.
Specifically, the broadcast server 100 may call the external audio/video in advance by a preset time length according to the broadcast start time of the target program in the program list, so as to perform pre-rebroadcast on the external audio/video.
For example, the broadcast control module 102 in the broadcast server 100 may generate an audio/video signal rebroadcasting task according to the program list, and set the task execution time according to the broadcast start time of the target program in the program list. And the task execution time is earlier than the preset time length of the starting broadcast time of the target program in the program list.
The broadcast control module 102 may send a scheduling instruction to the scheduling server 400 according to the task execution time of the audio/video signal relay task by using an immediate control instruction. The dispatch server 400 may call the audio/video to be rebroadcast from the external device according to the dispatch instruction, and forward the called audio/video to a preset multicast address.
When the pre-playing time is close, the decoding module 103 in the playing server 100 may pull the audio/video stream to perform a pre-rolling action (i.e., pre-acquisition), so that when the program is switched, seamless switching between the video and the audio can be realized. In the embodiment of the present invention, when at least two adjacent programs are to-be-relayed programs, the broadcast server 100 may schedule at least two external audio/video signals, where one of the audio/video signals is used for audio/video broadcast of a currently relayed program, and the remaining audio/video signals perform a pre-rolling action, so that seamless switching between video and audio can be realized when a next relayed program is switched.
Alternatively, as shown in fig. 1, the aforementioned external device may include: IP gateway 600 and other IP devices 700. Among other things, other IP devices 700 may include, but are not limited to: at least one of a studio and a general control system of the target channel.
As an alternative embodiment, as shown in fig. 1, the system for detecting a program broadcasted before broadcasting for IP may further include: a signal switch 500.
The signal switch 500 may be configured to receive the audio and video of the target program sent by the broadcast server 100, and send the audio and video to the detection server 200. The signal switch 500 may also be configured to receive the audio and video to be rebroadcast sent by the external device, and send the audio and video to be rebroadcast to the broadcast server 100.
As shown in fig. 1, the broadcasting server 100 may output a plurality of audio/video signals to the signal switch 500, and the detection server 200 may obtain the plurality of audio/video signals from the signal switch 500, specifically, each channel may output one audio/video signal to the signal switch 500. For example, the decoding module 103 in the broadcast server 100 may output the decoded audio/video stream corresponding to the channel a to the signal switch 500, so that the detection server 200 may obtain the corresponding audio/video stream from the signal interaction machine for analysis and detection.
As shown in fig. 1, the playout server 100 can also obtain audio and video signals (corresponding to the input multi-path signals in fig. 1) sent to the signal switch 500 by multiple external devices (such as the IP gateway 600 and other IP devices 700) from the signal switch 500. For example, when a program is broadcasted, the decoding module 103 in the broadcast server 100 may pull the audio/video stream corresponding to the program from the signal switch 500, so that the broadcast server 100 may play the corresponding audio/video.
As an optional embodiment, the preset detection rule according to the embodiment of the present invention may include: and at least one item of detection content and the detection result of each item of detection content meet the condition of outputting alarm information. For example, the detection content may be: the definition of the video image is output when the definition of the video image is smaller than or equal to a preset definition value, otherwise, the condition of outputting the alarm information is not met; the detection content can also be whether the audio is in reverse phase or not, alarm information is output when the audio is in reverse phase, and otherwise, the condition for outputting the alarm information is not met. Therefore, the detection server 200 may also be configured to generate alarm information and send the alarm information to the user equipment 200 when a detection result of the target detection content satisfies a condition for outputting the alarm information; user device 200 may also be used to receive alert information and display the alert information.
Wherein the target detection content is one of the at least one item of detection content. The alarm information comprises target detection content and an alarm reason.
In the embodiment of the invention, the alarm information can show the specific detection content and the alarm reason of the specific program, so that auditors can determine the problem and correspondingly process the problem, thereby preventing broadcasting accidents. In addition, in the embodiment of the invention, the alarm condition is set, and the alarm information is output when the alarm condition is reached, so that automatic filtering alarm and convergence alarm are realized, and alarm overflow is avoided.
Optionally, the alarm information may further include an alarm manner, such as instructing the user device 200 to display an exclamation mark in a flashing state, so as to remind the auditor, thereby reducing the probability of occurrence of the auditor missing the alarm information.
Optionally, the at least one item of detection content may include: the program name, the program duration, the program start time, the program end time, the broadcast channel, the broadcast signal source device, the signal source name, the broadcast channel name of the broadcast server 100, etc. of the target program; whether the audio and video corresponding to the target program has poor broadcasting conditions such as a black field condition, a static frame condition, a mute condition, a color bar condition, a color field condition, a sound loss condition, an audio inversion condition, a condition that the audio is higher than a first preset value, a condition that the audio is lower than a second preset value, and the like. Wherein the first preset value is larger than the second preset value.
In the case that the target program is an audio/video material to be played, which is locally stored in the broadcast server 100, the material file may be checked before playing, and therefore, the at least one item of detection content may further include: material file name, material file ID, material file type, material file in-point and material file out-point, whether a material file is missing, etc.
By checking the material files before broadcasting, the method is also beneficial to reducing the occurrence of broadcasting accidents. For example, when detecting that a material file is missing, the detection server 200 may send a detection result including information of the missing material file, a program name of the missing material file, and a scheduled broadcast time of the program (i.e., a broadcast time in a program list) and alarm information to the user equipment 200 to remind an auditor, so that the auditor can process the program before the program is officially broadcast, for example, store the missing material file in the material storage module 105 of the broadcast server 100.
Alternatively, for some detected contents, the detection server 200 may refer to the program information and the material information in the program guide for judgment. The program and material information referred by the detection server 200 may be synchronized by the broadcast server 100 to the detection server 200, that is, "synchronized broadcast receipt information" shown in fig. 1, and therefore, the broadcast server 100 may also be configured to send the program and material information to the detection server 200 after obtaining the program and material information. The detection server 200 may be further configured to receive the program list and the material information sent by the broadcast server 100, and detect the first detection content according to the program list and the material information. Wherein, the first detection content may include: the program name of the target program, the program duration, the program start time, the program end time, the broadcast channel, the broadcast signal source device, the signal source name, the broadcast channel name of the broadcast server 100, the material file name, the material file ID, the material file type, the material file in-point and material file out-point, whether the material file is missing, and the like.
Finally, it should be noted that the modules in the playout server 100 and the detection server 200 may be entity modules or virtual modules, which is not limited in this embodiment of the present invention. Furthermore, all the servers described in the embodiments of the present invention may be 86 servers, i.e., CISC (complex instruction set) architecture servers. In addition, the equipment and the server participating in the interaction in the program broadcasting detection system need to perform clock synchronization and are unified to the same time line.
In summary, the pre-broadcast detection system for IP-oriented broadcasting according to the embodiment of the present invention realizes automation of pre-broadcast audit, improves pre-broadcast audit efficiency, reduces the occurrence of missed detection, and improves program broadcasting safety. In addition, the program pre-broadcasting detection system for IP broadcasting provided by the embodiment of the invention can give consideration to the pre-broadcasting audit of the local audio and video material and the external audio and video to be rebroadcast, so that the pre-broadcasting detection is more comprehensive, and the safety of program broadcasting is further improved.
The system for detecting a program before broadcasting for IP broadcasting according to the embodiment of the present invention is described above, and a method for detecting a program before broadcasting for IP broadcasting according to the embodiment of the present invention is described below with reference to the accompanying drawings.
The embodiment of the invention provides a program detection method before broadcasting for IP broadcasting, which is applied to a detection server in the program detection system before broadcasting for IP broadcasting.
As shown in fig. 2, the method for detecting programs broadcasted in IP-oriented manner before broadcasting includes:
step 201: and acquiring a target program to be played of a target channel to be played in advance.

Finally, the detection server may automatically store the broadcasted process log and the detection result in a second database of the detection server.
Step 203: and sending the detection result to the user equipment so that the user equipment displays the detection result.
In the embodiment of the invention, after the detection server generates the detection result, the detection result can be sent to the user equipment, so that the user equipment can display the detection result, and the examination and check of auditors are facilitated.
The method for detecting the program played before the IP broadcasting can analyze and detect the program played before according to the preset detection rule and obtain the detection result, thereby realizing the automatic examination of the program before the broadcasting, omitting the manual examination operation, improving the detection efficiency, reducing the occurrence of the missed examination and improving the safety of the program broadcasting. In addition, the generated detection result can be sent to the user equipment, so that the user equipment can display the detection result for an auditor to check the detection result, and thus, the auditor can take measures in advance in time when finding the broadcasting fault according to the detection result, and the probability of the broadcasting fault is reduced.
As an alternative embodiment, the target program may be an audio/video material to be played, which is locally stored by the broadcast server, or an audio/video to be rebroadcast, which is acquired by the broadcast server from an external device.
In the embodiment of the invention, the broadcasting server can automatically carry out pre-decoding broadcasting on the audio and video material to be broadcasted, can also schedule external audio and video, and carries out pre-rebroadcasting on the external audio and video according to the program list.
The embodiment of the invention not only can carry out the pre-broadcasting audit of the pre-broadcasting audit on the audio and video materials stored in the local database of the broadcasting server, but also can realize the pre-broadcasting audit of the external audio and video signals by automatically scheduling the external audio and video signals in advance, thereby increasing the checking means, leading the pre-broadcasting audit to be more comprehensive and improving the broadcasting safety of programs.
For the explanation of the foregoing two pre-broadcast conditions of the target program, reference may be specifically made to the description in the pre-broadcast detection system for programs broadcast in IP, and details are not described here again.
As an optional embodiment, the preset detection rule according to the embodiment of the present invention may include: and at least one item of detection content and the detection result of each item of detection content meet the condition of outputting alarm information.
For example, the detection content may be: the definition of the video image is output when the definition of the video image is smaller than or equal to a preset definition value, otherwise, the condition of outputting the alarm information is not met; the detection content can also be whether the audio is in reverse phase or not, alarm information is output when the audio is in reverse phase, and otherwise, the condition for outputting the alarm information is not met.
In step 102: according to a preset detection rule, detecting the audio and video corresponding to the target program which is broadcast in advance, and after a detection result is generated, the method can further comprise the following steps:
and generating alarm information and sending the alarm information to user equipment under the condition that the detection result of the target detection content meets the condition of outputting the alarm information.
Wherein the target detection content is one of at least one item of detection content; the alarm information comprises target detection content and an alarm reason.
In the embodiment of the invention, the alarm information can show the specific detection content and the alarm reason of the specific program, so that an auditor can determine the problem and correspondingly process the problem, thereby preventing the broadcasting accident. In addition, in the embodiment of the invention, the alarm condition is set, and the alarm information is output when the alarm condition is reached, so that automatic filtering alarm and convergence alarm are realized, and alarm overflow is avoided.
Optionally, the alarm information may further include an alarm manner, such as instructing the user equipment to display an exclamation mark in a flashing state, so as to remind the auditor, thereby reducing the probability of the auditor missing the alarm information.
Optionally, the at least one item of detection content may include: the program name, the program duration, the program start time, the program end time, the broadcasting channel, the broadcasting signal source equipment, the signal source name, the broadcasting channel name of the broadcasting server and the like of the target program; whether the audio and the video corresponding to the target program have poor broadcasting conditions such as a black field condition, a static frame condition, a mute condition, a color bar condition, a color field condition, a sound loss condition, an audio inversion condition, a condition that the audio is higher than a first preset value, a condition that the audio is lower than a second preset value and the like. Wherein the first preset value is larger than the second preset value.
Under the condition that the target program is the audio and video material to be played and locally stored by the playing server, the material file can be checked before playing, so that the at least one item of detection content can further comprise: material file name, material file ID, material file type, material file in-point and material file out-point, whether a material file is missing, etc.
By checking the material files before broadcasting, the method is also beneficial to reducing the occurrence of broadcasting accidents. For example, when detecting that a material file is missing, the detection server may send a detection result including information of the missing material file, a program name of the missing material file, and a scheduled broadcast time of the program (i.e., a broadcast time in a program list) and alarm information to the user equipment to remind an auditor, so that the auditor can process the program before the program is officially broadcast, for example, store the missing material file in the material storage module 105 of the broadcast server.
Alternatively, for some detected contents, the detection server may refer to the program information and the material information in the program list for judgment. The program and the material information referred by the detection server may be synchronized by the broadcast server to the detection server, that is, "synchronized broadcast receipt information" shown in fig. 1, so that the detection server may receive the program and the material information sent by the broadcast server, and detect the first detection content according to the program and the material information. Wherein, the first detection content may include: the program name, the program duration, the program start time, the program end time, the broadcasting channel, the broadcasting signal source equipment, the signal source name, the broadcasting channel name of the broadcasting server, the material file name, the material file ID, the material file type, the material file in point and the material file out point of the target program, whether the material file is missing or not, and the like.
