本发明属于广播电视播出系统技术领域，具体涉及一种电视台播出设备的共享方法及系统。The invention belongs to the technical field of radio and television broadcasting systems, and in particular relates to a method and system for sharing television broadcasting equipment.
背景技术Background technique
在电视台的播出中，视频服务器播出基本取代录像机播出，作为播出中的核心设备，但考虑播出安全需要，防止视频服务器故障，或者素材不能及时到位等造成视频服务器无法播出的情况，一般采用录像机作为辅助播出设备，在视频服务器出现问题，或者素材来不及传输到视频服务器的时候，采用录像机播出。一般一个频道配置2台录像机，用于在视频服务器故障情况下，多个节目的交替播出。如果视频服务器故障不能使用，那么要用录像机完成播出单内节目的播出，由于节目交替播出的时候要求0帧精确（无缝隙），所以至少需要2个以上的录像机完成，例如，顺序播出a、b、c三个节目，使用n、m两个录像机，使用n录像机播出a节目，同时将b节目在录像机m准备好，在a节目播出结束后，b节目开始播出，在节目b的播出过程中，将c节目在录像机n准备好，依次类推。可见，一个频道至少需要2个录像机，才能保证节目的安全播出（视频服务器之所以可以完成，是因为视频服务器内的节目存储是非线性的，视频服务器可以保证存储的各个节目依次无缝播出）。所以在一般的电视台中，采用视频服务器播出的同时，每个频道需要配备2台录像机作为应急播出使用，如图1所示。In the broadcasting of TV stations, the broadcasting of the video server basically replaces the broadcasting of the video recorder as the core equipment in the broadcasting. However, considering the safety needs of the broadcasting, it is necessary to prevent the failure of the video server, or the failure of the material to be in place in time, which will cause the video server to fail to broadcast. Generally, video recorders are used as auxiliary broadcasting equipment. When there is a problem with the video server, or when the material is too late to be transmitted to the video server, the video recorder is used for broadcasting. Generally, one channel is equipped with two video recorders, which are used for alternate broadcasting of multiple programs in the event of a video server failure. If the video server fails and cannot be used, then the video recorder must be used to complete the broadcast of the programs in the broadcast list. Since the program requires 0 frame accuracy (no gap) when the program is broadcast alternately, at least two or more video recorders are required to complete it. For example, the sequence Broadcast three programs a, b, c, use two video recorders n and m, use video recorder n to broadcast program a, and prepare program b on video recorder m at the same time, after the broadcast of program a, program b starts to broadcast , during the broadcasting of program b, prepare program c on video recorder n, and so on. It can be seen that a channel needs at least 2 video recorders to ensure the safe broadcast of the program (the reason why the video server can be completed is that the program storage in the video server is non-linear, and the video server can ensure that the stored programs are seamlessly broadcast in sequence ). Therefore, in a general TV station, while using a video server to broadcast, each channel needs to be equipped with 2 video recorders for emergency broadcasting, as shown in Figure 1.
按每个频道配置2台录像机计算，一个省级台，一般8到15个频道，需要16到30台录像机作为应急设备。而录像机实际使用的频率并不高，除上文描述的视频服务器故障（极小概率出现），就是个别新闻节目来不及传输到视频服务器时采用录像机紧急播出，这种现象1天也不会超过1次，所以录像机在全天24小时中，绝大多数时间是闲置的。这样，录像机的闲置现象非常严重，而录像机的造价非常昂贵，这样就造成电视台投资很大的浪费。Calculated by configuring 2 video recorders for each channel, a provincial station generally has 8 to 15 channels and needs 16 to 30 video recorders as emergency equipment. The frequency of actual use of video recorders is not high. Except for the video server failure described above (which occurs with a very small probability), individual news programs are broadcast urgently by video recorders when they are too late to be transmitted to the video server. This phenomenon will not exceed one day. 1 time, so the video recorder is idle most of the time in 24 hours a day. Like this, the idle phenomenon of video recorder is very serious, and the cost of video recorder is very expensive, so just causes the very big waste of TV station investment.
