SYSTEMS AND METHODS OF REDUCING MEDIA STREAM DELAY THROUGH INDEPENDENT DECODER CLOCKS |
摘要 |
In one embodiment, a method of reducing video delay in a program stream comprises: setting an audio reference clock to an initial value based on a presentation timestamp for a frame that is the first decodable frame in the audio stream; setting a video reference clock to an initial value based on a presentation timestamp for a frame that is the first decodable frame in the video stream; starting audio and video reference clocks responsive to the later of a minimum buffer fill delay and receipt of a frame that is the first entire decodable frame in the video stream; decoding the audio stream in accordance with the audio reference clock; and decoding the video stream in accordance with the video reference clock. |
