  • Patent number: 10074382
    Abstract: The present document relates to the determination of a 200 bitrate related to an encoded bitstream, and describes a method for determining an estimate of a bitrate of a bitstream comprising a sequence of frames comprising a varying number of bitsand corresponding to excerpts of an audio and/or video signal. At least two frames of the sequence of frames comprise a parameter indicative of a processing delay for the corresponding frame. The method comprises determining: a total number of bits for a subsequence of frames from the bitstream; a corrected number 201 of frames based on a number of frames comprised within the subsequence and the parameters of at least two frames of the subsequence; and a lower bitrate bound and an upper bitrate bound of the bitrate based on the total number of bits, the corrected number of frames and a frame rate of the bitstream.

  • Patent number: 9883213
    Abstract: Methods for generating a transport stream (e.g., an MPEG-2 transport stream) such that the transport stream has at least one perfect splicing property, and/or such that the transport stream is indicative of at least one audio/video program and includes metadata indicative of whether the program has a perfect splicing property. Other aspects are methods for splicing such a transport stream, audio/video processing units (e.g., splicers) configured to perform any embodiment of the inventive method, and audio/video processing units which include a buffer memory which stores at least one segment of transport stream generated in accordance with any embodiment of the inventive method.
