Abstract:
Particular embodiments generally relate to providing different censoring levels for audio-video streams. In one embodiment, an audio-video stream is received. Metadata including censoring information for the audio-video stream is also received. The audio-video stream and metadata may be sent by a source in separate streams. A first level of censoring associated with a first receiver is determined along with a second level of censoring for a second receiver. A first audio-video stream is generated for the first receiver with a first censor level and a second audio-video stream is generated for the second receiver with a second censor level. For example, the first audio-video stream may include censoring of faces and the second audio-video stream may be an audio-video stream without censoring or may censor some other part of the audio-video. The first audio-video stream and the second audio-video stream are then sent to the first and second receivers, respectively.
