Description
Technical Field
The invention relates to a high-performance DVB program sharing method for a terminal, and belongs to the technical field of set top box application.
Background
For watching broadcast and television live broadcast television programs, different people have different requirements, for example, the old people like watching dramas, children like watching animations, young people like watching heddles, movies and other programs, and the requirements are inconsistent, and for the situation, the existing solution methods generally have two kinds, one of which adopts a live broadcast sharing technology, but the technology has the problems of low performance or influence on the existing service by the function thereof in the using process, so the technology is not integrally realized on a set top box; secondly, interconnection of a plurality of set top boxes is adopted, but the purpose of the added set top boxes is only to be used as a gateway with high cost, so that the problem of high cost exists, and the set top boxes cannot be accepted by the majority of family users.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a high performance DVB program sharing method for a terminal with low cost, which can overcome the defects of the prior art.
The technical scheme of the invention is as follows: a high-performance DVB program sharing method for a terminal comprises the terminal, wherein the terminal is a broadcasting and television set-top box with a hot spot, the method comprises the steps of obtaining DVB programs through demux resources in the terminal, then pushing recorded contents to an ngnix server or a similar ngnix self-realization server in a rtmp protocol mode through ffmpeg or similar self-realization software, and enabling the ngnix server to receive rtmp requests of various terminals such as a mobile phone and a smart television to share the DVB programs.
In the high-performance DVB program sharing method for the terminal, the obtaining of the DVB program by the demux resource is recorded through a PVR module in the terminal, and the recorded content is directly stored through a memory Buffer.
The high-performance DVB program sharing method for the terminal is that the terminal issues recorded contents to an rtmp server, and the issuing is completed by simply establishing internal socket communication between the corresponding program contents in the TS stream and the server in an rtmp protocol packet mode, without requiring ffmpeg or realizing any coding and decoding functions of software. .
The high-performance DVB program sharing method for the terminal is that, for the case that the frequency points carry small-resolution programs, the terminal issues all the programs once from recording to issuing in the method.
The high-performance DVB program sharing method for the terminal is that the terminal performs multithreading processing on a push streaming request response.
The high-performance DVB program sharing method for the terminal is characterized in that both a single Tuner and a double Tuner of the terminal can be used, when the single Tuner is used, whether DVB live broadcasting is currently carried out is judged, if yes, Tuner resources are preempted, friendly prompts are given, and if not, the current live broadcasting is not influenced.
Compared with the prior art, the method provided by the invention has the following beneficial effects:
1. the invention can carry out high-efficiency sharing on DVB programs by software modification or even only installing one APK on the basis of the existing set top box with hot spots, does not need to introduce other hardware, and provides broadcasting and television family live broadcast resources and can simultaneously watch the sharing requirements of different programs on the premise of increasing several money costs.
2. And the recording and the releasing are transmitted by adopting an internal memory, and the rtmp is preferentially selected by the transmission protocol for releasing, so that the flash is prevented from being frequently operated, and the service life of the stable operation of the set top box can be further ensured.
3. The method does not generate the flow cost of the mobile terminal when watching the radio and television video resources in the local area network, and enjoys high-definition and stable visual experience.
4. The invention realizes a method for sharing high-performance DVB programs of multiple terminals on a set-top box similar terminal, wherein the DVB programs can be large-resolution programs for large screens or small-resolution programs for small screens such as mobile phones, one frequency point can contain a plurality of large-resolution programs or can contain dozens of small-resolution programs, and the specific strategy is determined by the specific strategy of a local operator and is realized by matching with the corresponding strategy of a client.
Drawings
Fig. 1 is a general technical module framework diagram of the present invention.
FIG. 2 is a hardware block diagram of the present invention.
Detailed Description
Embodiment 1, as shown in fig. 1, the terminal is a radio and television set-top box with a hot spot, a controller module in the radio and television set-top box with the hot spot may be a background service in Android, and monitors a request on a network, and if there is another terminal that needs to watch a live program, it may be determined whether the current terminal is using DVB live broadcast, if it is sending an instruction to a display module, a prompt box is popped up or another prompt or advertising page is switched, and then the following steps are performed:
1. locking the appointed or configured frequency point, starting demux filtering, and calling PVR (hardware or software implementation) to record all programs of the frequency point;
and 2, storing the content recorded by the PVR module into a Buffer, and continuously reading the content recorded by the PVR by realizing a read-back-call-packet function of ffmpeg avio _ alloc _ context. The programming language is as follows:
static int iFillIobuffer(void * opaque,uint8_t *buf, int bufsize){
U8* pStreamBuf = NULL;
S32 s32buffersize = -1;
U32 valid=0;
PVR_Read_parameter *pstRead= &_stRead;
//pStreamBuf u32buffersize
while(!pstRead->bTerminate){
pStreamBuf = PvrRingBuffer;
valid = mRingBuffer->GetValidBufferSize();
if(valid>bufsize){
valid=bufsize;
}
s32buffersize = mRingBuffer->Read(pStreamBuf, valid);
if(s32buffersize > 0){
memcpy(buf,pStreamBuf,s32buffersize);
break;
}else{
//ALOGD("iFillIobuffer no data:s32buffersize=%d,valid=%d",s32buffersize,valid);
}
usleep(2000);
}
return s32buffersize;
}
ffmpeg configuration output publishes all programs to nginx service in rtmp protocol.
And 4.ngnix receives the live broadcast requests of various terminals.
The scheme is implemented by secondary development on a set top box terminal with a hot spot, namely original hardware is not changed, only one APK is upgraded, and a television user can enjoy the function of watching live programs through multiple terminals, wherein the hardware block diagram is shown in figure 2: wherein the CPU is typically a chip supporting one-way video decoding.
