Step 105, when operational order comprises set-top box device control command, carry out the operation corresponding with set-top box device control command according to set-top box device control command controller set top box device.
What deserves to be explained is, the executive agent of the embodiment of the present invention is a kind of set-top box device, can be android set top box, also can be the intelligent TV set with set-top box functionality, but not only be confined to this.
The data sharing of the android set top box that the embodiment of the present invention provides and the method for control, the video data play in set-top box device and voice data can be synthesized audio, video data, and be stored in the buffer circle of set-top box device, and be connected by carrying out TCP with RTU (remote terminal unit), when receiving audio, video data request, can according to audio, video data request, send the audio, video data corresponding to audio, video data request to RTU (remote terminal unit), play this audio, video data to make RTU (remote terminal unit); In addition, when receiving set-top box device control command, the operation corresponding with this set-top box device control command can be carried out according to set-top box device control command controller set top box device.Thus when user leaves set-top box device, the HD video that android set top box provides or Web content can be watched, and can control android set top box.
What deserves to be explained is, the operation of above-mentioned correspondence comprises the television channel of switching machine set top box device, broadcast sound volume, electric program menu operation, closedown set-top box device, the locking set-top box device of conditioner set top box device and unlocks set-top box device etc., but is not only confined to this.
In order to make those skilled in the art better understand the present invention, enumerate a more specifically embodiment below, as shown in Figure 2, the data sharing of the android set top box that the embodiment of the present invention provides and the method for control, comprising:
Step 201, set-top box device intercept each frame video image in set-top box device system kernel before frambuffer process and the pcm audio flow data in set-top box device system kernel, and be stored in buffer circle, and mark each frame video image and the system time corresponding to each section of pcm audio flow data.
In the system of android set top box, the process of video image is, by the local Graph Manager of SurfaceFlinger module, different layer is synthesized a sub-picture, then be filled in back buffer module, fill completely when back buffer module and first the front buffer in system is set to back buffer, again original back buffer state is set to front buffer, then by the frame buffer zone (framebuffer) of system kernel, video image is shown on screen.And the voice data process in the system of android set top box is by Advanced Audio Coding (Advanced AudioCoding, being called for short AAC) audio conversion of form changes pulse code modulation (Pulse Code Modulation into, be called for short PCM) audio stream, and directly give audio frequency apparatus output sound by kernel.
Therefore, in above-mentioned steps 201, each frame video image before needing frambuffer process in system kernel intercepts, and is stored in buffer circle.Pcm audio flow data is intercepted simultaneously and be stored in buffer circle.So just obtain the initial data of Voice & Video.Also relate to the synchronous of Voice & Video herein, can be realized by mutual exclusion lock mode, namely lock for during sky at back buffer, until at release lock when back buffer is full.The thread simultaneously obtaining pcm audio flow data by one is deposited current pcm audio number flow data in buffer circle, and mark obtains the system time of each section of pcm audio flow data.So just can ensure the corresponding one section of pcm audio flow data of each frame video image.
Each frame video image is encoded to H264 standard data by the ffmpeg code database in set-top box device system by step 202, set-top box device, and pcm audio flow data is encoded to AAC formatted data.
H264 standard data and the synthesis of AAC formatted data, according to this system time, are encapsulated as MP4 form audio, video data by ffmpeg code database by step 203, set-top box device.
MP4 form audio, video data is stored in the buffer circle of set-top box device by step 204, set-top box device.
The timing of step 205, set-top box device carries out udp broadcast outside set-top box device.
Wherein, the content of udp broadcast comprises IP address and the port numbers of set-top box device.UDP in udp broadcast is User Datagram Protoco (UDP) (User Datagram Protocol is called for short UDP).
Step 206, RTU (remote terminal unit) send TCP connection request according to the IP address of set-top box device and port numbers to set-top box device.
Concrete, a transmission control protocol (Transmission ControlProtocol, TCP) virtual server can be pre-created in set-top box device, for receiving the TCP connection request that RTU (remote terminal unit) sends.
Step 207, set-top box device and RTU (remote terminal unit) are carried out TCP and are connected.
Step 208, RTU (remote terminal unit) are to set-top box device transmit operation instruction.
Wherein, operational order comprises audio, video data request or set-top box device control command.
When operational order comprises audio, video data request, perform step 209; When operational order comprises set-top box device control command, perform step 210.
Step 209, set-top box device, according to audio, video data request, send the audio, video data corresponding to audio, video data request to RTU (remote terminal unit), play to make RTU (remote terminal unit) to audio, video data.
Such as, when user leaves set-top box device, watch audio/video program if also need by this set-top box device, be then connected with the TCP of set-top box device by RTU (remote terminal unit), directly can obtain the audio, video data in set-top box device buffer circle.
RTU (remote terminal unit) operating data in set-top box device control command is converted to Android system key assignments by step 210, set-top box device.
Wherein, RTU (remote terminal unit) operating data can comprise the various content of operation to remote terminal, such as on a touch-screen mobile phone, can be left and right, upper inferior slip gesture, namely the operation corresponding to the correspondence on set-top box device that Android system key assignments completes can be and regulates volume or switching channels etc.
Step 211, set-top box device carry out the operation corresponding with set-top box device control command according to Android system key assignments controller set top box device.
What deserves to be explained is, the operation of above-mentioned correspondence comprises the television channel of switching machine set top box device, broadcast sound volume, electric program menu operation, closedown set-top box device, the locking set-top box device of conditioner set top box device and unlocks set-top box device etc., but is not only confined to this.
Step 212, set-top box device send the state information of carrying out audio, video data after corresponding operation or set-top box device to RTU (remote terminal unit).
Concrete, if the electric program menu that is operating as of such as correspondence operates, and have selected the program in electric program menu, then set-top box device will send corresponding audio, video data to RTU (remote terminal unit).If being operating as of correspondence is closed set-top box device, locking set-top box device or unlocks set-top box device, then set-top box device is by the state information to RTU (remote terminal unit) transmitter set top box device, such as the information such as " set-top box device is closed ", " set-top box device is locked ".
Carry out the operation corresponding with set-top box device control command by set-top box device according to Android system key assignments controller set top box device, the Long-distance Control to set-top box device can be realized.Such as, when the head of a family stays out, some children can see TV by set-top box device, and now the head of a family can pass through RTU (remote terminal unit) (as smart mobile phone) and controls set-top box device, as long-range closedown Set Top Box, remote lock Set Top Box etc.
The state information of the audio, video data carried out after corresponding operation or set-top box device shows by step 213, RTU (remote terminal unit).
