Systems and Methods for Encoding Alternative Streams of Video for Use in Adaptive Bitrate Streaming

摘要

Systems and methods for encoding alternative streams for use in adaptive bitrate streaming based upon the delay of each stream in accordance with embodiments of the invention are described. One embodiment of the invention includes memory, and a processor configured by a source encoding application to: receive multimedia content, where the multimedia content includes source video data having a primary resolution and a primary sample aspect ratio; and encode the source video data as a set of alternative video streams, where: the alternative video streams have different maximum bitrates; and the alternative video streams are encoded to have an upper bound seek delay that is equal to or less than the upper bound seek delay of streams in the set of alternative video streams that are encoded at a higher maximum bitrate.

1. A source encoder configured to encode source video as a number of alternative video streams, the source encoder comprising:
memory; and a processor configured by a source encoding application to:
receive multimedia content, where the multimedia content comprises source video data having a primary resolution and a primary sample aspect ratio; andencode the source video data as a set of alternative video streams, where:the alternative video streams have different maximum bitrates; andthe alternative video streams are encoded to have an upper bound seek delay that is equal to or less than the upper bound seek delay of streams in the set of alternative video streams that are encoded at a higher maximum bitrate.
