Embodiment
For make purpose of the present invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The schematic flow sheet of the set-top box startup method embodiment one that Fig. 1 provides for the embodiment of the invention may further comprise the steps:
S101, each business module in the set-top box is carried out initialization;
After set-top box powers on, at first each business module is carried out initialization, finish some basic parameter configuration,, guarantee that set-top box can normally receive audio, video data and carry out decoding and displaying so that each business module of follow-up startup carries out work.Each business module comprises demultiplexing module, audio/video decoding module and display control module.
S102, start described each business module, and control described each business module and carry out operate as normal, realize the broadcast of audio, video data according to initialization result.Concrete, the control demultiplexing module is carried out the parsing of program transport streams and the filtration of audio, video data; Control audio/video decoding module realizes the decoding of audio, video data; The control display control module is finished the demonstration output control of decoding rear video data, guarantees that display terminal can the display video picture.
S103, load operation system and application program.
In the present embodiment, after set-top box powers on, start each business module earlier, guarantee the demonstration output of audio frequency and video, and then load operation system and application program, therefore the user can watch the program picture in the short period of time, and needn't wait for the time of the loading of operating system and application program, has improved the speed of set-top box electrifying startup.
The schematic flow sheet of the set-top box startup method embodiment two that Fig. 2 provides for the embodiment of the invention may further comprise the steps:
Step S201, set-top box starts, and CPU powers on.
Step S202 reads initialization information.Wherein, initialization information comprises that each business module starts required basic parameter: the audio frequency and video passage of demultiplexing module demultiplexing and program PID (ProgramIdentification, the program identification), PID comprises video identification VID, audio identification AID, clock reference signal identification PCR, and facsimile signal identification, be used for the differentiation of decoder identification transmission code stream data packet signal kind, multiple programs packet; The data buffer address of audio/video decoding module decoding usefulness and read-write pointer, and audio decoder initialization sample rate and volume setting; The display parameters setting that display control module is required.Wherein program PID and display parameters can write down the preceding broadcast program information of power down, also can be provided with by the user; Also fixedly initialization setting of set-top box manufacturer in addition selects to play advertisement etc.
Step S203 utilizes above-mentioned initialization information that each business module (comprising demultiplexing module, audio/video decoding and display module) is carried out initialization, finishes the basic parameter configuration.
Step S204 after finishing initialization and being provided with, starts demultiplexing module, audio/video decoding and display module, and control audio/video decoding flow process guarantees smooth play (the step S205) of audio frequency and video.
Unusual needs to audio/video decoding course carry out abnormality processing; Video PTS (the Presentation Time Stamp that need obtain according to video decode, the predetermined demonstration time of first addressed location in System Target Decoder of representing this grouping) and the audio frequency PTS that obtains of audio decoder, carrying out audio sync regulates, when finding the audio frequency and video step-out, carry out synchronous correction, to guarantee result of broadcast.After each business module startup work, can see video pictures at display terminal.
Step S206 after finishing aforesaid operations, carries out the loading of operating system and application program again.The load operation of operating system and application program is for the decoding and the not influence of broadcast of audio/video program.
In the embodiment of the invention, after set-top box powers on, can start audio/video decoding and show and handle, therefore can see the program picture very soon after powering on, the program picture of being seen can be provided with when initialization, can be programme information and relevant parameters before the last power down.The set-top box start-up control method that adopts the embodiment of the invention to provide has greatly improved set-top box electrifying startup speed, powers on an audio/video program broadcast time of about 2 seconds of need from set-top box.
Also can directly broadcast broadcast TV program behind the set-top box electrifying startup, the user can be provided with program channel, also can be defaulted as the program of playing before the power down, saves the stand-by period of user's TV reception; Upper layer application also can load and to finish startup and play advertisement etc. during this period of time in the CPU operating system that powers on, and has improved the toggle speed and the control efficiency of set-top box, has enriched application scenarios.
The set-top box structural representation that Fig. 3 provides for the embodiment of the invention, as shown in Figure 3, media management module 34 and CPU 30.CPU 30 is used for business module and media management module 34 are carried out initialization, and starts media management module 34, and after media management module 34 starts described business module, load operation system and application program.The operating system here can be embedded operating system kernel, and application program can be broadcast program, browsing page, TV program guide etc.
Media management module 34 is used to start described business module, and controls the broadcast that described business module is realized audio, video data.Before media management module 34 started business module, CPU 30 was carried out initialization and is started media management module 34 media management module 34 earlier.
Wherein, as shown in Figure 3, business module can comprise: demultiplexing module 31, be used for program transport streams is resolved, and obtain audio, video data; Audio/video decoding module 32 is used for the audio, video data that described demultiplexing module 31 obtains is decoded; Display control module 33 is used for the video data that 32 decodings of audio/video decoding module obtain is shown output control.
