    摘要: Devices and methods for processing multimedia data to generate enhanced quality multimedia data at the receiver based on encoder assisted post-processing. In one aspect, processing multimedia data includes identifying an indicator of a post-processing technique, encoding first multimedia data to form first encoded data, processing the first encoded data to form second multimedia data, the processing comprising decoding the first encoded data and applying the post-processing technique identified by the indicator, comparing the second multimedia data to the first multimedia data to determine difference information indicative of differences between the second multimedia data and the first multimedia data, and generating second encoded data based on the difference information.

    摘要: In one example, a method comprises defining a period of time for encoding a set of frames of multimedia data, encoding a first portion of the set of frames of multimedia data at a first encoding rate, encoding a second portion of the set of frames of multimedia data at a second encoding rate, wherein the second encoding rate is less than the first encoding rate so as to create a null interval during the period of time, transmitting the encoded set of frames via a transmitter, and blanking the transmitter during the null interval.

    摘要: In general, this disclosure describes techniques for encoding and decoding sequences of video frames using fragmentary reference pictures. The disclosure presents video encoding and decoding techniques for modified temporal compression based on fragmented references rather than complete reference pictures. In a typical sequence of video frames, only a portion (i.e., a tile) of each frame includes moving objects. Moreover, in each frame, the moving objects tend to be confined to specific areas that are common among each frame in the sequence of video frames. As described herein, such common areas of motion are identified. Pictures are then extracted from the identified areas of the video frames. Because these pictures may represent only portions of the frames, this disclosure refers to these pictures as “fragments.” It is then these fragments that are used as reference pictures for generating predicted frames during a motion compensation process, rather than the entire frame.
