Early rendering for fast channel switching

摘要

The disclosure relates to techniques for switching between channels of digital multimedia content. In particular, a decoding device decodes and renders to a display at least one frame of a segment of data prior to receiving the entire segment. In certain aspects, the decoding device may render one of the frames of the segment and freeze the rendered frame until the decoding device receives all of the frames of the segment. In other aspects, the decoding device may render frames of one or more segments at a reduced rendering rate until the receiving and rendering operations of decoding device are synchronized such that the rendering of the current segment occurs at substantially the same time as the receiving of the next segment. By rendering at least frame prior to receiving the entire segment the decoding device more quickly displays content to a user during a channel switching event.

主权项

1. A method for processing video data, the method comprising:
decoding at least one coded frame of a plurality of coded frames of at least a portion of a segment of the video data, wherein the at least one coded frame is received subsequent to a channel switch request; and rendering, in response to the channel switch request, the at least one decoded frame to a display before a playback time associated with the at least one decoded frame.
