摘要： A video transcoding system and method employing an improved rate control algorithm. A plurality of frames in an input video bitstream are received by the system, in which each frame is in a first coding format. Each frame in the input bitstream is decoded, and complexity information indicating the complexity of the frame after decoding is obtained. An estimated number of bits to allocate for the respective frame is calculated. Using a rate estimation model that employs the complexity information for the respective frame, a picture cost for the frame is calculated based on the estimated number of bits allocated to encode the frame, and a parameter of the rate estimation model. A target cost for the respective frame is calculated based at least in part on the picture cost 10 and the complexity information for the frame. A quantization parameter (QP) is calculated that, when used to encode the respective frame in a second coding format, would generate an encoded frame having an actual cost approximately equal to the target cost. The respective frame is encoded using the calculated QP, and the frames encoded in the second coding format are provided in an output video bitstream.

摘要： Systems and methods of measuring a temporal offset between audio content and video content that employ audio fingerprints from an audio signal in the audio content, and video fingerprints from video frames in the video content. The systems obtain reference audio and video fingerprints prior to transmission of video over a media channel, and obtain target audio and video fingerprints subsequent to transmission of the video over the media channel. Each fingerprint has an associated time stamp. Using the reference and target audio fingerprints and their associated time stamps, the systems determine an audio time stamp offset. Using the reference and target video fingerprints and their associated time stamps, the systems determine a video time stamp offset. Using the audio and video time stamp offsets, the systems determine a temporal offset between the video content and the audio content introduced by the media channel.
