Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
The present application will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart of an embodiment of a data distribution method provided by the present application, and fig. 2 is a schematic structural diagram of an embodiment of an audio/video transmission system provided by the present application.
The audio and video transmission system provided by the embodiment of the application is a one-to-many transmission system, and the audio and video transmission system is specifically composed of a sending terminal TX1, N receiving terminals RX1, RX2, … and RXN. The transmitting terminal TX1, the N receiving terminals RX1, RX2, …, RXN are respectively connected to the same network switch, and perform data communication and data transmission through the TCP ports of the network switch.
The network IP address of a sending terminal TX1 is IP0, the network IP addresses of N receiving terminals RX1, RX2 and … are respectively IP1, IP2 and …, and the IP addresses of the RXN are mutually accessed through the IP addresses. Both the sending end and the receiving end are provided with program controllers, and the process of the data distribution method in the embodiment of the application is realized by operating the program modules.
It should be noted that, in the following description of the embodiments, a sending end is used as an execution main body of the data distribution method, a first receiving end represents a receiving end to which audio and video data is to be distributed, and a second receiving end represents a receiving end to which audio and video data has been distributed.
As shown in fig. 1, the data distribution method according to the embodiment of the present application includes the following specific steps:
step S11: a first data request signal from a first receiver is obtained.
The transmitting end obtains audio and video signals to be transmitted through an audio and video source, samples and codes the audio and video signals to be transmitted, compresses the audio and video signals into audio and video data and then distributes the data. The transmitting end is provided with a data distribution program module, and after the transmitting end compresses and codes the audio and video signals into audio and video data, the data is distributed through the data distribution program module.
The receiving end of the embodiment of the application is provided with a data request program module and a data distribution program module, and the receiving end sends a first data request signal to the sending end through the data request program module so as to request the sending end to distribute audio and video data to the receiving end. Further, after the receiving end acquires the audio and video data, the acquired audio and video data can be decoded and output on one hand, and the acquired audio and video data can be distributed to other receiving ends through the data distribution program module on the other hand. Because the sending end and the receiving end are both provided with the data distribution program modules, the sending end or any one of the receiving ends can be used as data distribution equipment.
Specifically, the sending end listens to a program preset TCP port through a data distribution program module, and waits for and receives a first data request signal from a first receiving end. The first data request signal is a message sent by a receiving end of data to be acquired, the data request signal includes a data request receiving address of the first receiving end, and the data request receiving address of the first receiving end includes a network IP address of the first receiving end and a data request interception TCP port.
For example, a data request receiving address of a data distribution device whose network IP address is IP and whose TCP port is p is intercepted is denoted by (IP, p). In this embodiment of the application, data request receiving ports of a transmitting terminal TX1 and N receiving terminals RX1, RX2, …, and RXN are p0, p1, p2, and … pN, respectively, and corresponding data request receiving addresses are (ip0, p0), (ip1, p1), (ip2, p2), …, (ipN, and pN), respectively.
Step S12: and judging whether the current occupied distribution capacity value reaches the maximum distribution capacity value.
The data distribution program module is provided with process parameters of currently occupied distribution capacity, and the currently occupied distribution capacity is a distribution capacity reduction value caused by the fact that the data distribution program module of one data distribution device distributes data to a data request end. The maximum distribution capacity value of the data distribution equipment is the maximum connection number which can be simultaneously kept by the distribution equipment and is used for audio and video data transmission, and the currently occupied distribution capacity value is the connection number which is currently kept by the distribution equipment and is used for audio and video data transmission. The embodiment of the application can take the maximum connection number of the TCP for audio and video data transmission which can be kept by a data distribution program module of the data distribution equipment as the maximum distribution capacity value, and the maximum connection number is marked as E; the number of TCP connections that have been established with the data requesting device is taken as the current occupied distribution capability value, denoted K.
Therefore, the occupied distribution capacity value of the data distribution equipment ranges from 0 to the maximum distribution capacity value, and the current occupied distribution capacity value can be used for measuring the real-time distribution capacity of the data distribution equipment.
Specifically, the distribution capability of the data distribution device may be determined through experiments or calculations and each data distribution device is allowed to have different distribution capabilities, for example, in the embodiment of the present application, the number of TCP links for establishing distribution data between the data distribution device and the receiving end is pre-stored in each data distribution device in a program preset manner.
The occupied distribution capacity and the quantity of the established data distribution links can have a transformation relation and are obtained by calculation in the process of processing the data request by the data distribution equipment. For example, in the embodiment of the present application, the number of established TCP connections for data distribution is used as the occupied distribution capability, and every time a data distribution connection is added, the number of TCP connections for data distribution is increased by 1, and the value of the occupied distribution capability is increased by 1.
When the sending end obtains a first data request signal of a first receiving end, whether the current occupied distribution capacity value of the sending end reaches the maximum distribution capacity value is detected. If the current occupied distribution capacity value of the sending end does not reach the maximum distribution capacity value, the step S14 is carried out; if the currently occupied distribution capability value of the sender reaches the maximum distribution capability value, the process proceeds to step S13.
Step S13: and returning request failure response information and a data request receiving address of a second receiving terminal which has distributed the audio and video data based on the first data request signal, so that the second receiving terminal distributes the audio and video data to the first receiving terminal.
The request result of the embodiment of the application comprises success of data request and failure of data request. When the current occupied distribution capacity value of the sending end reaches the maximum distribution capacity value, the sending end needs to return a request result of data request failure to the first receiving end.
Specifically, the request result of the data request failure includes request failure response information and a data request receiving address of one of the second receiving terminals, so that the first receiving terminal can request the second receiving terminal to distribute the audio and video data, and at this time, the second receiving terminal serves as data distribution equipment to distribute the audio and video data.
The data distribution program module also comprises process parameters of the record list of the active distribution equipment, and the sending end can select a proper second receiving end as the data distribution equipment of the first receiving end by means of the record list of the active distribution equipment. Specifically, the first entry of the record table of the active distribution device is the data request receiving address of the device where the data distribution program module is located, for example, the first entry of the record table of the active distribution device of the sending end is the data request receiving address of the sending end, and the remaining entries are the data request receiving addresses of all the second receiving ends that have been distributed from the data distribution program module to the audio and video data. Specifically, the record table of the active distribution device is denoted as a, the mth entry in the table is denoted by a (m), and a (0) is the data request receiving address of the device where the data distribution program module is located.
Taking a sending end as an example, please refer to fig. 3 continuously for a process of establishing a record table of an active distribution device and a process of distributing audio and video data by using the record table of the active distribution device, and fig. 3 is a schematic flow diagram of another embodiment of the data distribution method provided by the present application.
As shown in fig. 3, the data distribution method according to the embodiment of the present application includes the following specific steps:
step S21: and establishing an activity distribution equipment record table, wherein the activity distribution equipment record table at least comprises a data request receiving address of a receiving end.
The sending end establishes an activity distribution equipment recording table, and the first table entry is a data request receiving address of the sending end.
Step S22: second data request information is obtained from a second receiver.
Step S23: and distributing the audio and video data to the second receiving terminal based on the second data request information of the second receiving terminal, and recording the data request receiving address of the second receiving terminal in the record table of the active distribution equipment.
When the occupied distribution capacity value does not reach the maximum distribution capacity value, the sending end directly distributes the audio and video data to the second receiving end, and records the data request receiving address of the second receiving end in the record table of the active distribution equipment.
Step S24: and when the current occupied distribution capacity value reaches the maximum distribution capacity value, selecting a data request receiving address of any second receiving end in the record table of the active distribution equipment.
When the first data request information from the first receiving terminal is obtained and the current occupied distribution capacity value reaches the maximum distribution capacity value, the sending terminal selects any one second receiving terminal and the data request receiving address A (i) thereof in the record list of the active distribution equipment, wherein i is larger than 0.
Step S25: and returning request failure response information and a data request receiving address of the second receiving terminal to the first receiving terminal, so that the first receiving terminal sends a third data request signal to the second receiving terminal based on the data request receiving address of the second receiving terminal, and the second receiving terminal distributes audio and video data to the first receiving terminal based on the third data request signal.
The sending end returns the request result of data request failure to the first receiving end, and disconnects the TCP connection with the current data request of the first receiving end, and the request result includes A (i) and is recorded as Ack (Fail, A (i)). The first receiving end acquires A (i) in the Ack (Fail, A (i)), and sends a third data request signal to the second receiving end based on the A (i). And when the second receiving terminal is used as data distribution equipment to judge that the occupied distribution capacity value of the second receiving terminal does not reach the maximum distribution capacity value, the second receiving terminal can distribute the audio and video data to the first receiving terminal.
Step S14: and returning request success response information based on the first data request signal, and distributing the audio and video data to the first receiving end.
When the current occupied distribution capacity value of the sending end does not reach the maximum distribution capacity value, the data distribution program module of the sending end keeps the TCP connection with the data request of the first receiving end, returns a request result Ack (Success, A (0)) of data request Success to the first receiving end, and can directly distribute audio and video data after successful response.
In the process of distributing the audio and video data, the sending end needs to increase the current occupied distribution capacity value, and records the data request receiving address of the first receiving end in a record table of the active distribution equipment of the sending end. And after the pronunciation video data is divided, the sending end recalculates the current occupied distribution capacity value.
According to the embodiment of the application, the data distribution function is added at the receiving end, the sending end is used as primary data distribution equipment, the second receiving end is used as secondary data distribution equipment, a data distribution network is formed in a self-adaptive mode by utilizing the audio and video data request-response process between the receiving end and the sending end to distribute the audio and video data, and the audio and video data distribution capability of the whole audio and video transmission system is improved.
Further, the secondary data distribution device is a receiver, i.e. a second receiver, that has already distributed the audio-video data. The secondary data distribution equipment can also distribute data in a mode of forwarding the data step by step, and the secondary data distribution equipment is divided into first secondary data distribution equipment, second secondary data distribution equipment, … and nth secondary data distribution equipment; the first secondary data distribution equipment acquires audio and video data from the primary data distribution equipment, and the mth secondary data distribution equipment acquires the audio and video data from the (m-1) th secondary data distribution equipment respectively and distributes the acquired audio and video data to the (m + 1) th secondary data distribution equipment; the composition of the mth secondary data distribution device need not be specified in advance, but rather is dynamically generated during the course of a data request.
In the embodiment of the application, a sending end obtains a first data request signal from a first receiving end; judging whether the current occupied distribution capacity value reaches the maximum distribution capacity value or not, and measuring the distribution capacity of the sending end through the distribution capacity value, so that the sending end is favorably controlled; if so, returning request failure response information and a data request receiving address of a second receiving terminal which has distributed the audio and video data based on the first data request signal so that the second receiving terminal distributes the audio and video data to the first receiving terminal; if not, returning request success response information based on the first data request signal, and distributing the audio and video data to the first receiving end. According to the method and the device, data distribution is carried out through the second receiving end, the requirement of the distribution capacity of the sending end is reduced, and the hardware cost and the complexity of the audio and video transmission system are reduced.
