Interaction figure during middleware processes IP data source that Fig. 2 provides for the embodiment of the invention between each unit.
For convenience of explanation, the process that the applications layer can be called middleware is divided into 3 stages: start the broadcast stage, Play Control stage, and dwell period.
Starting the broadcast stage, when administrative unit receives the initialization command that the applications layer sends, carrying out some initial work by administrative unit.This initial work comprises other unit that starts middleware, and generates some resource requirements, for example memory source etc.
Then, the applications layer can send one and open order, when administrative unit receives this order, generates the message of creating a player, and this message is delivered in the message queue of control unit.Create player by control unit according to this message control.At this moment, the applications layer can send the order that data source is set, when administrative unit receives the order that data source is set, that calls data capture unit is provided with the data source interface, by data capture unit the URL that media server provides is resolved, according to the marking head that parses, select IP data source unit.And, resolve the IP address and the port that obtain media server.
At this moment, the applications layer can send play command, when administrative unit receives play command, this play command is organized into broadcast message, and will play message and send in the message queue in the control unit.Control unit takes out this and plays message from message queue, and calls the playback interface of IP data source unit, and IP data source unit is according to the IP address and the port numbers of this media server, and foundation is connected with media server.And (Real Time Streaming Protocol RTSP) sets up session with media server by real-time streaming protocol in IP data source unit.After the RTSP order that receives the broadcast that digital television receiver sends, media server begins to send media data to network.Simultaneously, control unit calls the playback interface of demultiplexing bound cell, constantly receives the media data of being uploaded by media server from network by the demultiplexing bound cell, and starts the demultiplexing hardware unit.The demultiplexing hardware unit carries out demultiplexing to data, and Program Association Table (PAT), Program Map Table (PMT) are sent to the demultiplexing bound cell.The demultiplexing bound cell from pmt table, parse audio/video program Packet Identifier (Packer Identifier, PID), the program category of audio/video program.And the demultiplexing hardware unit sends the ES flow data that demultiplexing obtains to the decoding hardware unit.Simultaneously, control unit calls the playback interface of decoding plug-in unit, by decoding plug-in unit starting decoding hardware unit this ES stream is decoded, thereby has realized playing function.
In the Play Control stage, when the applications layer sends pause command, administrative unit is organized into suspending message with this pause command and sends in the message queue of control unit, control unit calls the time-out interface of IP data source unit, send the RTSP that suspends by IP data source unit and order, suspend the transmission media data with the notice media server to media server.Simultaneously, control unit calls the time-out interface of demultiplexing bound cell, receives data so that the demultiplexing plug-in unit suspends.And control unit also calls the time-out interface of decoding plug-in unit, and the decoding plug-in unit suspends the decoding of decoding hardware unit, suspends thereby make to play.
When needs continue to play, the applications layer sends one and recovers order, administrative unit is organized into recovery message with this pause command and sends in the control unit, control unit takes out this message from message queue, call the playback interface of IP data source unit, send the RTSP that plays by IP data source unit and order, so that media server resends media data to media server.Simultaneously, control unit calls the playback interface of demultiplexing bound cell.The demultiplexing bound cell restarts receiving network data and data is sent to the demultiplexing hardware unit, carries out demultiplexing by demultiplexing.Simultaneously, control unit also calls the playback interface of decoding plug-in unit.The decoding plug-in unit restarts the decoding hardware unit, thereby recovers to play.
When needs change broadcasting speed, for example F.F., rewind down, move back slowly at slow-motion, and the applications layer sends a shift command, administrative unit is organized into speed change message with this shift command and sends in the message queue of control unit, and control unit is according to the speed change interface of this message call IP data source unit.The RTSP that sends F.F. or reverse commands by IP data source unit is to media server, makes media server change transmission rate or transmits every frame.Simultaneously, control unit calls the speed change interface of decoding plug-in unit.Accelerate or the decode rate that slows down by decoding plug-in unit controls decoding hardware unit.
At dwell period, the applications layer sends ceases and desist order, when administrative unit receives this order, this is ceased and desisted order to be organized into stop message and send to control unit, call the interface that stops of IP data source unit by control unit, send the RTSP order that stops by IP data source unit to media server, by the session of media server disconnection with IP data source unit.Simultaneously, control unit calls the interface that stops of the demultiplexing bound cell of Plug_in unit and decoding plug-in unit, so that the demultiplexing bound cell, and the decoding plug-in unit controls the demultiplexing hardware unit respectively, and the decoding hardware unit stops.When the applications layer sent shutdown command, administrative unit was organized into close message with this shutdown command, and this close message is sent to control unit, closed player by control unit control, discharged corresponding resource simultaneously.
