Abstract (en)

[origin: WO2013109179A1] An output process for outputting decoded pictures (35) of a video stream (1) from a decoded picture buffer (34, 48) in a decoder (40, 50) involves calculating a picture order count limit based on at least one syntax element retrieved based on an encoded representation (20) of a current picture (2) of the video stream (1). Decoded reference pictures (35) stored in the decoded picture buffer (34, 48) and having a respective picture order count value lower than the picture order count limit are then output from the decoded picture buffer (34, 48). The output process reducing output delay in connection with picture decoding, in particular for temporally scaled video streams.
