Abstract:
Systems and methods that use differential values to represent decoding and presentation times (64) of pictures are provided. Optionally, some of the systems or the methods may use an entropy coding method (48) such as, for example, the Universal Variable Length Code (UVLC) for the differential time stamps.
Abstract:
Systems and methods that transmit and display progressive video with hints for interlaced display (22) are provided. The systems and methods may find use in, for example, digital video compression systems. In one embodiment, a system or a method encodes video by following the native frame rate of the source material and, if desirable, embeds hint information for interlaced display (22) into the coded bitstream (20). Presentation times for coded pictures may be generated using the hint information (22). The hint information (22) may be used or ignored.
Abstract:
Systems (40, 50, 70, 80) and methods (120, 130, 140, 150, 160, 170) of coding progressive content with isolated fields for conversion to interlaced display are provided. Some systems and methods may find use in, for example, digital video compression systems and methods. Film material may be encoded as video material with an intended field polarity and an explicit 3:2 pull-down operation for interlaced display (e.g., a 30-frames-per-second display).
