时间码是在广播、电视设备中使用的一种绝对地址编码。当磁带录音机记录上时间码以后,就在磁带上录上了与节目信号完全同步的地址信号。利用时间码的控制功能,可以实现录音机与录音机,录音机与录像机或其它设备之间的完全同步。并可以方便地进行信号的切换,混合以及配音等工作。以往时间码大多用于录像机,现在在录音机中也越来越广泛地采用这种控制方式了。这对于广播、电视节目的制作和播出,产生了很大的影响。
Time code is an absolute address code used in radio and television equipment. After the tape recorder records the time code, an address signal that is completely synchronized with the program signal is recorded on the tape. With timecode control, complete synchronization between the recorder and recorder, recorder and recorder or other device can be achieved. And can easily switch the signal, mixing and dubbing work. Much of the time-code used in the past for video recorders is now being used more and more widely in tape recorders. This has had a big impact on the production and broadcast of radio and television programs.
