Abstract:
1. A nonlinear editing system comprising: a video encoder to receive a first video stream including video originally intended as video for a scene of a program and a second video stream including a first alternate video for replacing the video, the video encoder inserting video synchronization marks into the video and the first alternate video; an audio compressor to receive a first audio stream including audio originally intended as audio for the scene of the program and a second audio stream including a first alternate audio for replacing the audio, the audio compressor inserting audio synchronization marks into the audio and the first alternate audio, wherein the video and audio synchronization marks, respectively, include a primary clock reference, decoding time stamp, and presentation time stamp; and an engine unit to synchronize the video with the first alternate video using the video synchronization marks and to synchronize the audio with the first alternate audio using the audio synchronization marks so that, where the scene of the program includes objectionable content, (i) the video is substituted with the first alternate video, (ii) the audio is substituted with the first alternate audio, or (iii) both the video and the audio are substituted with the first alternate video and the first alternate audio.
