Abstract:
1. In a computing device that implements a video decoder, a method comprising: with the computing device that implements the video decoder, receiving and processing a first bitstream element in sequence layer in a bitstream for a video sequence; with the computing device that implements the video decoder, receiving and processing a second bitstream element in the sequence layer in the bitstream for the video sequence, wherein frame coding mode is variable between progressive, field-interlaced and frame-interlaced for individual frames within the video sequence, and where the first and second bitstream elements in the sequence layer indicate whether the bitstream includes (a) both the repeat-picture element and a field-order element per frame, (b) the repeat-picture element but not the field-order element per frame, or (c) neither the repeat-picture element nor the field-order element per frame; with the computing device that implements the video decoder, receiving and processing frame data in frame layer of the bitstream for frame in the video sequence, wherein the first bitstream element indicates whether the repeat-picture element is present or absent in the frame data in the frame layer of the bitstream, including: with the computing device that implements the video decoder, decoding the frame using the frame data.
