例如，家里有两台电视，但是只有一个机顶盒，可以两个电视的节目是同一个信号源的同一个节目，比如都是中央1台的节目，也可以是同一个信号源的同一个频点下的不同节目，比如卫星信号源中星6B 3840频率下的中央1台和中央3台；也可以是不同信号源的节目，如可以用第一台电视播放cable信号源的湖南卫视的节目，第二台电视接收播放卫星信号源的高清中央5台的节目，这样可以收看多种信号源节目。而且在播放节目的同时可以支持录制功能，录制的模式也可以有多种，在不同的音视频播放器上可以进行相同节目的播放和录制，也可以进行不同节目的播放和录制，播放和录制的模式有以下几种：For example, there are two TVs in the house, but there is only one set-top box, and the programs of the two TVs can be the same program of the same source, such as one program in the center or the same frequency point of the same source. Different programs, such as the satellite signal source in the center of the 6B 3840 frequency, the central one and the central three; can also be different signal source programs, such as Hunan TV, which can use the first TV to broadcast the cable source, The second TV receives 5 high-definition central programs that broadcast satellite signals, so that you can watch multiple source programs. Moreover, the recording function can be supported while playing the program, and the recording mode can also be various. The same program can be played and recorded on different audio and video players, and different programs can be played and recorded, played and recorded. The modes are as follows:

在步骤340中，当机顶盒接收到对所述第一实时音视频数据的播放控制命令时，停止将所述第一实时音视频数据输出至第一音视频播放器；通过解码器从所述硬盘中取出存储的第一传送流进行解码得到第一存储音视频数据，将所述第一存储音视频数据输出至第一音视频播放器。In step 340, when the set top box receives the play control command for the first real-time audio and video data, stop outputting the first real-time audio and video data to the first audio-video player; from the hard disk through the decoder The stored first transport stream is decoded to obtain first stored audio and video data, and the first stored audio and video data is output to the first audio and video player.
播放控制命令可以包括：暂停、快进、慢放和倒退等命令。The play control commands may include: pause, fast forward, slow release, and reverse commands.
例如，第一音频数据是中央1台的动物世界节目第300集，此时机顶盒收到了对当前播放的动物世界进行暂停的命令，则停止对当前视频的播放，当机顶盒收到播放命令时，直接从硬盘中取出存储的中央1台的动物世界节目的第300集，从暂停的位置继续进行播放，方便用户随时进行观看。For example, the first audio data is the 300th episode of the animal world program in the center. At this time, the set top box receives the command to pause the currently playing animal world, and stops the playback of the current video. When the set top box receives the play command, The 300th episode of the stored animal world program in the center is directly taken out from the hard disk, and playback is continued from the paused position, so that the user can watch it at any time.
例如，第一音频数据是中央1台的动物世界节目第300集，当机顶盒收到了对当前播放的动物世界进行倒退的命令时，则从硬盘中取出存储的中央1台的动物世界节目的第300集，回放当前视频之前的视频内容；当机顶盒收到了对当前播放的动物世界进行慢放的命令时，则从硬盘中取出存储的中央1台的动物世界节目的第300集，并调整视频的播放速度，如正常的播放速度为60帧/秒，进行慢放时，播放速度可以调整为30帧/秒；在电视机播放机顶盒中已存储的视频内容时，可以进行快进操作，例如当机顶盒从硬盘中取出存储的中央1台的动物世界节目的第300集进行播放时，收到了对当前播放的节目进行快进的命令，则对当前播放的视频内容进行快进。 For example, the first audio data is the 300th episode of the animal world program in the center. When the set-top box receives the command to reverse the currently playing animal world, the first stored animal central program in the central unit is taken out from the hard disk. 300 episodes, playing back the video content before the current video; when the set-top box receives the command to slow down the currently playing animal world, the third episode of the stored central animal world program is taken out from the hard disk, and the video is adjusted. The playback speed, such as the normal playback speed of 60 frames / sec, when slow playback, the playback speed can be adjusted to 30 frames / sec; when the TV plays the video content stored in the set-top box, you can fast forward operation, for example When the set top box retrieves the 300th episode of the stored central animal program from the hard disk for playback, it receives a command to fast forward the currently played program, and then fast forwards the currently played video content.
在步骤350中，当机顶盒接收到对所述第一实时音视频数据的模式切换命令时，停止将所述第一实时音视频数据输出至第一音视频播放器；通过解码器从所述硬盘中取出存储的第二传送流进行解码得到第二存储音视频数据，将所述第二存储音视频数据输出至第一音视频播放器。In step 350, when the set top box receives the mode switching command for the first real-time audio and video data, stop outputting the first real-time audio and video data to the first audio-video player; from the hard disk through the decoder The stored second transport stream is decoded to obtain second stored audio and video data, and the second stored audio and video data is output to the first audio and video player.
模式切换命令是指从当前播放的这一种模式信号源切换到已经保存在硬盘中的另一种模式信号源。当机顶盒收到从第一模式信号源切换到第二模式信号源时，停止将第一音视频数据输出至第一音视频播放器，停止第一音视频播放器对第一模式信号源的第一音视频数据进行播放；通过解码器从硬盘中取出存储的第二传送流进行解码得到第二音视频数据输出至第一音视频播放器进行播放。The mode switching command is to switch from the currently playing one mode source to another mode source that has been saved in the hard disk. When the set top box receives the switch from the first mode signal source to the second mode signal source, stops outputting the first audio and video data to the first audio and video player, and stops the first audio and video player from the first mode signal source. The audio and video data is played; the stored second transport stream is retrieved from the hard disk by the decoder for decoding, and the second audio and video data is output to the first audio and video player for playback.
例如，在同时接收的两种模式的信号源为cable信号和卫星信号，cable信号收到的是湖南卫视的节目，卫星信号收到的是中央2台的节目。用户在边看湖南卫视节目的同时设置录制中央2台的节目。当用户想看已录制的中央2台的节目时，机顶盒接收相应的模式切换命令，停止播放湖南卫视的节目，从湖南卫视的节目切换到录制了的中央2台的节目继续播放，从硬盘中取出的录制信号不受信号不好时播放不流畅等的影响，在信号不好的时候也可以流畅的播放。For example, the signals of the two modes received at the same time are the cable signal and the satellite signal, the cable signal receives the program of Hunan Satellite TV, and the satellite signal receives the programs of the central two. The user sets up to record the two programs in the center while watching the Hunan Satellite TV program. When the user wants to watch the recorded 2 central programs, the set-top box receives the corresponding mode switching command, stops playing the Hunan Satellite TV program, and switches from the Hunan Satellite TV program to the recorded central 2 program to continue playing, from the hard disk. The recorded signal that is taken out is not affected by the smoothness of the playback when the signal is not good, and can be played smoothly when the signal is not good.
在步骤360中，当机顶盒接收到对所述第二实时音视频数据的播放控制命令时，停止将所述第二实时音视频数据输出至第二音视频播放器；通过解码器从所述硬盘中取出存储的第二传送流进行解码得到第二存储音视频数据，将所述第二存储音视频数据输出至第二音视频播放器。In step 360, when the set top box receives the play control command for the second real-time audio and video data, stop outputting the second real-time audio and video data to the second audio-video player; from the hard disk through the decoder The stored second transport stream is decoded to obtain second stored audio and video data, and the second stored audio and video data is output to the second audio and video player.
在步骤370中，当机顶盒接收到对所述第二实时音视频数据的模式切换命令时，停止将所述第二实时音视频数据输出至第二音视频播放器；通过解码器从所述硬盘中取出存储的第一传送流进行解码得到第一存储音视频数据，将所述第一存储音视频数据输出至第二音视频播放器。In step 370, when the set top box receives the mode switching command for the second real-time audio and video data, stop outputting the second real-time audio and video data to the second audio-video player; from the hard disk through the decoder And extracting the stored first transport stream to obtain the first stored audio and video data, and outputting the first stored audio and video data to the second audio and video player.
