Fig. 3 is the flow chart of the acceptance control method according to a kind of Real Time Streaming shown in an exemplary embodiment.
The acceptance control method of this Real Time Streaming is used for the data receiver 110 shown in Fig. 1.As it is shown on figure 3, this real-time streaming passes
Defeated acceptance control method, can be performed by data receiver 110, may comprise steps of.
In the step 310, exclusive Real Time Streaming after control command receiving or sending thread self is triggered and carries out digital independent
In data receiving channel.
Wherein, the control command receiving or sending thread of indication can be that in data receiver, arbitrary needs is controlled order reading
Thread.Data receiving channel in Real Time Streaming for realize media data transmission in Real Time Streaming and with
Media data transmission control command transmission alternately.It is to say, the data of transmission are intertexture in data receiving channel
Data.
After a control command receiving or sending thread is triggered execution data read process, this control command receiving or sending thread application number
According to the control of reception passage, with exclusive data receiving channel.
Concrete, control command receiving or sending thread is triggered after execution data read process, first carries out request for data reception
The control of passage asks exclusive data receiving channel, then judges the exclusive the most successful, if not becoming of data receiving channel
Merit, then proceed the application of data receiving channel control, until exclusive data receiving channel.
For this control command receiving or sending thread having monopolized data receiving channel, subsequent data reception can be led to by it
In road, the data of transmission are read out；And for other thread, will be prohibited to carry out the read operation of data, the most right
The execution that thread-data reads provides protection.
In one exemplary embodiment, in data receiver, the line data in data receiving channel can being read out
Journey is multiple, and substantially can be divided into two big classes, and one is control command receiving or sending thread, and two is digital independent thread.Control life
Making receiving or sending thread is for obtaining the thread of control command in data receiver, and media data reads thread and is responsible for obtaining media
The thread of data.
At this it should be noted that in the Real Time Streaming that carried out of data receiver, the thread of operation includes controlling
Order receiving or sending thread and media data read the big class of thread two, and the quantity of each class thread can need to carry out spirit according to actual operation
Live and adjust.
In a step 330, carry out data receiver by exclusive data receiving channel, these data also exist media number
According to.
Wherein, in the Internet at exclusive data receiving channel place, the data of server transport are received.For exclusive number
For control command receiving or sending thread according to reception passage, it is in order to obtain control command from data receiving channel.
But, the data receiving channel that control command receiving or sending thread is monopolized, it is before receiving control command,
The most inevasible receiving media data, therefore, the data receiving channel monopolized at control command transceiver channel is entered
In the data receiver of row, there is the reception of media data.
In step 350, in the data receiver carried out, control command receiving or sending thread is controlled order and media data
Reading, buffered media data wait digital independent thread read.
Wherein, control command receiving or sending thread will read Internet, i.e. its data receiving channel monopolized and be received and obtain
Data.It should be understood that in the Real Time Streaming carried out during control command receiving or sending thread monopolizes data receiving channel,
The data received, on the one hand include media data, and the control command transmitted subsequently；On the other hand, these data received
It is media data, it addition, these data received can also is that control command.
It follows that during control command receiving or sending thread monopolizes data receiving channel, it may appear that same data receiver leads to
Road is sequentially received the scene of media data and control command, and under this scene, control command receiving thread will be controlled life
Order and the reading of media data, and cache the media data of reading.
In step 370, the data receiving channel that during reading of control command, release is exclusive is completed.
Wherein, perform the thread of digital independent, i.e. control command receiving or sending thread and complete the reading of its control command carried out
After taking, discharge exclusive data receiving channel immediately, in order to other thread can carry out the reading of data.
In the reception of Real Time Streaming as above controls, each thread alternately data receiving channel only
Account for, so realize its in data receiving channel to receive data reading, thus data receiving channel is alternately present
For media data and control command, it is possible to realize the orderly reading of Various types of data, and formed when carrying out digital independent
Protection mechanism it also avoid thread self and originally need the data read to be read to walk by other thread, control under multi-thread mechanism
Data receiver properly functioning.
Fig. 4 is the description carried out according to the details to step 330 shown in an exemplary embodiment.Thread is control command
Receiving or sending thread, as shown in Figure 4, step 330, may comprise steps of.
In step 331, sending request by control command receiving or sending thread, request waits for data when being sent and connects
Receive the reception of data in passage.
Wherein, control command receiving or sending thread is for realizing the reading of control command in data receiving channel.Control command is also
Non-server actively sends, but needs after server sends request, can receive this request of server response and
The control command returned.In one exemplary embodiment, to server send request in carry transmission command method, with
It is easy to server this is responded.
Concrete, that control command receiving or sending thread is made requests on by data transmitting channel transmission, at data transmitting channel
Middle realize the data receiver transmission to the request of server.
In step 333, carrying out data receiver at data receiving channel, the data of reception include the control command of request.
Wherein, when server sends data, data receiving channel all will carry out the reception of data.Reception in these data
In, owing to control command thread have sent request to server, the data that therefore data receiving channel receives contain clothes
The control command that business device is responded request and sent.
Thus it will be clear that for control command receiving or sending thread, at its data receiving channel carried out
Time exclusive, completing the transmission of request and the reception of control command, whole transmission request is until receiving the whole mistake of control command
Journey has been carried out protection, and is not restricted to receive this stage of control command.
If this is because go request for data to receive the control of passage the most again, in the feelings that application is failed
Under condition, the control command of server response is the most very likely read by other thread, and then causes mistake.
Therefore, when control command receiving or sending thread needs the reading being controlled order, it should realize before request sends
Monopolizing of data receiving channel, and then avoid the generation of data read errors.
Additionally, the ratio that the data volume shared by Qing Qiu is shared by whole Real Time Streaming is extremely low, major part is media
Data, and server to request response speed be exceedingly fast, therefore, send request until receiving the whole process of control command
The of short duration of the data receiving channel carried out is monopolized, and can't impact for program feature.
Embodiment corresponding to Fig. 3 is combined, it is provided that control command transmitting-receiving line in data receiver in Fig. 4 correspondence embodiment
The process that Cheng Shixian control command receives.Data receiver also exists one or more control command receiving or sending thread, at Fig. 3
Corresponding embodiment provides control command receiving or sending thread and realizes the flow process that realizes of control command reception, and right in Fig. 4 institute
The realization of data receiver after data receiving channel exclusive in Fig. 3 is provided more detailed concrete real by the embodiment answered
Show, and then the digital independent realized by control command receiving or sending thread provides guarantee.
Fig. 5 is the description carried out according to the details to step 350 shown in an exemplary embodiment.Transmission data are for controlling
Order, as it is shown in figure 5, step 350, may comprise steps of.
In step 351, along with the reception of data in data receiving channel, it is judged that whether the data of reception are media number
According to, if it has not, then perform step 353, if it has, then perform step 355.
Wherein, foregoing, the data receiving channel that control command receiving or sending thread is monopolized, its number received
According to, include the control command that server response asks to be returned.
Server is that control command thread is controlled to the transmission of control command, and i.e. control command thread is to service
After device have sent request, this just can be responded by server, to return control command；For media data, it is by taking
Business device actively sends to data receiver.
It follows that even if control command receiving or sending thread has monopolized data receiving channel, data receiving channel still may be used
The media data that server actively sends can be received.It is to say, data receiving channel received data, including controlling life
Order, in addition, may also include media data.
When control command receiving or sending thread is controlled the reading of order, it is necessary first to identify media data in the data received
Existence, and then the media data that on the one hand will exist for digital independent thread caching, on the other hand be only the reading of control command
Take.
In one exemplary embodiment, it is judged that whether the data of reception are that media data can initiateing according to media data
Character realizes.
In media data, it is $ (0x24) that first character, i.e. leader are known, and therefore, finds first in the received data
Character is $ (0x24), then the data at this character place are media data.
In step 353, it is controlled the reading of order.
Wherein, monopolize the control command receiving or sending thread of data receiving channel after have sent request to server, with
In data receiving channel, receive control command, for control command receiving or sending thread, be directly controlled order
Read.
In one exemplary embodiment, the bebinning character of control command is a specific character, such as, with the character of R switch,
Such as RTSP**, and control command terminates with new line, i.e. and CRLF is end mark, therefore, can be according to controlling life
Bebinning character and the end mark of order find the data corresponding to control command in the received data, and then are read out
Come.
In step 355, buffered media data waits that digital independent thread reads.
Wherein, for the existence of media data in the data receiving channel that control command receiving or sending thread is monopolized, also will enter
The reading of row media data, and cache this media data.
It is to say, for the media data arriving data receiving channel prior to control command, control command receiving or sending thread
Cross-thread read and caches, to avoid occurring the situation of data read errors, also ensure that media data reads thread follow-up
The digital independent carried out.
In one exemplary embodiment, control command receiving or sending thread is when reading out media data, by media data cache
To FIFO (First Input First Output, FIFO) queue, to realize the pre-cache of media data, and at FIFO
Under the effect of queue, improve subsequent media digital independent thread and carry out the efficiency of media data lookup.
In one exemplary embodiment, it is according to media data that the media data that control command receiving or sending thread is carried out reads
In initial character carry out, the follow-up all digital independent that will start with character $ (0x24) are complete.
Should further illustrate at this, in data receiving channel receive data, although be control command and
Media data intertexture exists, but is not to mix, i.e. control command and media data is to intersect but is that independent completion exists
's.
Fig. 6 is according to the existing forms schematic diagram of data in the data transmission shown in an exemplary embodiment.As shown in Figure 6
, media data 410 and control command 430 are the partial data sections of separate existence.In media data 410, character $
(0x24) it is its leader and knows 411.In control command 430, bebinning character is with the character of R beginning, i.e. RTSP/1.0
200OK。
Therefore, control command receiving or sending thread, for the data in data receiving channel, can know 411 realizations according to its leader
The reading of media data 410, it is also possible to realize the reading of control command 430 according to the character started with R.
In the embodiment that Fig. 3 and Fig. 4 is realized, in conjunction with the embodiment corresponding to Fig. 5, in control command receiving or sending thread institute
The data receiving channel carried out is exclusive with in the reading realization of data in data receiving channel, is entered by control command receiving or sending thread
The control command of row reads to provide and implements, and the intertexture existence being media data and control command in the data of reception carries
Supply the process that realizes reading control command and the process to existing media data, and then realized under multi-thread mechanism
The control command of control command receiving or sending thread reads.
Fig. 7 is the flow chart of the acceptance control method according to a kind of Real Time Streaming shown in an exemplary embodiment.
Being triggered, to carry out the thread of digital independent be that media data reads thread, as it is shown in fig. 7, the reception of this Real Time Streaming controls
Method, may comprise steps of.
In step 510, after digital independent thread self is triggered and carries out digital independent, it may be judged whether there is the matchmaker of caching
Volume data, if it has, then perform step 530, if it has not, then perform step 550.
Wherein, foregoing, control command receiving or sending thread is when its exclusive data receiving channel, for existing in data
Media data, carried out reading and caching process, in follow-up digital independent, read the media of caching for other thread
Data.
Media data reads thread and carries out media data reading in data receiving terminal, so that media data is supplied to phase
The application answered.Therefore, media data reading thread is triggered when carrying out digital independent, will first determine whether the media data of caching
In, if there is its required media data, if it is present need not read from data receiving channel, but directly
Connect the media data reading caching.
In step 530, the media data of caching is read.
Wherein, after judging the media data obtaining having there is caching, media data reads thread and directly carries out media
The reading of data, now will need not exclusive data receiving channel, it is not required that carry out data in data receiving channel
Read.
In step 550, digital independent thread monopolizes the data receiving channel in Real Time Streaming.
Wherein, if there is not media data in Huan Cun to read the media data corresponding to thread, then need to count
According to the application of reception passage control, with exclusive data receiving channel, and then side is capable of media number in data receiving channel
According to reading.
By mode as above, under multi-thread mechanism, read thread for media data in data receiver provide
What media data read realizes process.During realizing at this, media data reads thread and control command receiving or sending thread is mutual
Coordinate so that the reception of media data and control command is read and will not be got muddled, and then is also not result in data read errors
Situation occur.
Here, by Fig. 7 correspondence embodiment, the media data reading thread constituted at Fig. 1 and Fig. 1 and Fig. 5 is carried out
In the embodiment that media data reads, provide for media data read step and implement, and then by enforcement corresponding for Fig. 7
In example, solving under multi-thread mechanism, media data reads the carrying out of thread read operation relative to media data, prior to reaching several
During according to reception passage, the reading problem of media data, and then the media data reading that media data thread is carried out can
Under multi-thread mechanism properly functioning.
Additionally, combine Fig. 4 with Fig. 5 to be distinguished corresponding embodiment, under the multi-thread mechanism of data receiver, it is provided that
What media data reading thread and control command receiving or sending thread cooperated implements, and ensures to interweave under multi-thread mechanism with this
The reading of data, prevent data-crosstalk, it is to avoid system in case of system halt or media decoder are abnormal.
In acceptance control method according to a kind of Real Time Streaming shown in an exemplary embodiment, step 370 it
After, the acceptance control method of this Real Time Streaming, it is also possible to comprise the following steps.
Judge whether the digital independent that media data reading thread is carried out terminates, if it has not, then return step 510, if
It is yes, then terminates.
Wherein, also needing to proceed if reading the digital independent that carried out of thread at media data, i.e. yet suffering from
The media data not read, the most now, aforementioned for return described media data is read thread and carries out the realization of digital independent
Process, i.e. returns step 510.
Understand in conjunction with embodiment corresponding for Fig. 1 with Fig. 7, read thread at media data and need nonetheless remain for carrying out media data reading
When taking, first return step 510 is carried out the judgement of the media data cached, if for media data reads thread,
There is not the media data of caching, then need to be realized by exclusive data receiving channel the reading of media data.
Distinguished corresponding embodiment by Fig. 3, Fig. 4, Fig. 5 with Fig. 7, achieved multi-thread mechanism for data receiving terminal
Lower control command receiving or sending thread and media data read thread and cooperate the reading of carried out interleaving data, are i.e. controlling life
The control command and the media data that make receiving or sending thread and media data read between thread interlaced transmission realize the accurate of data
Read, thus will improve reliability and efficiency that under multi-thread mechanism, interleaving data reads.
Below will be with data receiver as Set Top Box, as a example by server is RTSP server, in conjunction with concrete application scenarios, retouch
State the acceptance control method of this Real Time Streaming.
The transmission of media data is carried out based on its agreement such as TCP, UDP or RTP/RTCP, and its transmission control is then
By real-time streaming protocol, i.e. RTSP protocol realization.
Corresponding transmission means concrete example is as shown in the table:
| Transmission means | Explanation |
| MP2T/TCP | Use TCP directly to carry MPEG2-TS, do not use RTP encapsulation |
| MP2T/UDP | Use UDP directly to carry MPEG2-TS, do not use RTP encapsulation |
| MP2T/RTP/TCP | RTP based on TCP is used to carry MPEG2-TS |
| MP2T/RTP/UDP | RTP based on UDP is used to carry MPEG2-TS |
Wherein, MPEG2 represents the audio and video data streams of TS stream format, and MPEG2-TS is the data stream of transmission, i.e. media
Data.
Here, with Transmission Control Protocol for illustrating.
In media data transmission based on Transmission Control Protocol, control command is also to use Transmission Control Protocol to realize, and i.e. controls life
Order and media data use same port, and i.e. for data receiver, control command and media data are present in same TCP number
According to receiving passage, there is the mixed transport of control command data and media data.
In transmission realizes, by sending the request carrying transmission command method to RTSP server, control with this
The transmitting-receiving process of control command；And for media data transmission, then server actively sends,
In RTSP standard, for carrying out the mode of media data carrying based on TCP, it is allowed to control command and media data
Interweaving, the most all transmitted by TCP, to realize penetrating of fire wall, Fig. 8 is according to the media number shown in an exemplary embodiment
According to form, media data contains 0x24 leader know 411.
The transmission of control command and media data is carried out interting, therefore, for data receiver, i.e. and Set Top Box institute
The process performed, will be also that order performs.Such as, Fig. 9 is according to suitable in the data receiver shown in an exemplary embodiment
Sequence performs schematic diagram, and i.e. reading media data 610, transmission request 630 and reading control command 650 is that order performs.

Bright, ideal model as shown in Figure 10 will be obtained.
In Fig. 10, the longitudinal axis represents the task of execution, and transverse axis is time shaft, represents that CPU time slice runs axle.Can from Figure 10
Know, if the segmentation of CPU time slice, just carry out according to the complete cycle of one-off, then consistent, no with under single-threaded scene
Can come into question.
But, it practice, owing to the distribution of CPU time slice is to be determined by the dispatching algorithm of operating system, not completely
Ideal model can be met, herein it is possible to there will be the result shown in Figure 11.
In fig. 11, media data 1 and media data 2 are one group of complete data, but are divided into 2 CPU time slice
Perform, and the reading of the transmission asked and control command is also partitioned into 2 CPU time slice and performs.
On this basis, further regard to Figure 12, if CPU time slice does change shown in Figure 12, read media data 1 He
Read in the CPU time slice between media data 2, also insert the control command that server returns, and then media data 1, control
Order and media data 2 receive conduits weave at same tcp data and exist.
Owing to control command is between media data 1 and media data 2, if media data reads thread and performs reading
After media data 1, server returns control command, now, media data read thread read obtain may the most not
It is media data, but control command；And for control command receiving or sending thread, read to walk owing to media data reads thread
Control command, the most also will not read control command, and then cause system disorders, and then also results in later stage command character solution
Analysis is abnormal, even crashes or media decoder is abnormal.
Accordingly, it would be desirable to realize in media data transmission based on disclosure Fig. 3, embodiment that Fig. 4, Fig. 5 are corresponding with Fig. 7
Receive and control, and then the accurate reading of media data and control command can be realized under many mechanism.
Figure 13 is to control process according to the reception of Real Time Streaming under the multi-thread mechanism shown in an exemplary embodiment
Flow chart.
Control command receiving or sending thread illustrated in fig. 13 represents and performs the class thread that control command reads in Set Top Box,
Media data reads thread and then represents the class thread performing media data reading in Set Top Box.
According to the embodiment corresponding to Fig. 3 and Fig. 4, control command receiving or sending thread will perform step 810 to shown in step 840
Process, the transmission made requests on when exclusive tcp data receives passage and the reception of control command.
According to the embodiment shown in Fig. 5, control command receiving or sending thread, by being made whether to exist the judgement of media data, is i.e. sentenced
Whether disconnected data are to start with 0x24, perform step 850 to 870 processes crossed.
When reading media data, it is deposited into fifo queue.
For media data read thread, its be triggered carry out digital independent time, will realize corresponding to Fig. 1 and Fig. 7
Embodiment.
Concrete, perform step 910, first determine whether whether fifo queue exists its required media data read,
If it has, then directly this media data is read to applying, i.e. step 920.
If it is not, exclusive tcp data receives passage, perform step 930 and step 940.Now, by exclusive
Tcp data receives channel reception media data, and media data reads thread and directly reads from tcp data reception passage.
Here, by the process shown in Figure 13 so that control command receiving or sending thread and media data read thread and mutually join
Close, it is achieved the interleaving data under multi-thread mechanism reads.
Further, embodiment illustrated in fig. 13 corresponding time program process as shown in Figure 14 and Figure 15.
In the embodiment shown in fig. 13, control command receiving or sending thread and media data read thread and perform the suitable of digital independent
Sequence does not set, but needs to perform respectively digital independent according to actual motion.
Therefore, Figure 14 shows that control command receiving or sending thread reads thread prior to media data and performs digital independent, and is
Media data reads thread and has carried out the cross-thread pre-cache of media data.
Now, media data reads thread and is not required to receive passage reading media data from tcp data, and only from FIFO
Queue reading media data.
Figure 15 shows that media data reads thread and performs the time program process of digital independent prior to control command receiving or sending thread,
In the process, the pre-cache of media data, therefore, media data read line are not carried out due to control command receiving or sending thread
Journey needs to receive passage reading media data at exclusive tcp data.
