Dynamic streaming plural lattice video coding representations of video

摘要

A first sequence of pictures may be partitioned into plural representations, each of the plural representations may be encoded independently of each other with a common time base, a first portion of the plural encoded representations may be provided based on a first network condition, the first portion having a first bit-rate, and a second portion of the plural encoded representations may be provided having a second bit-rate different than the first bit-rate, wherein a switch from providing the first portion to providing the second portion is responsive to a second network condition different than the first network condition.

主权项

1. A method, comprising:
encoding plural representations having a respective sequence of latticed pictures, wherein a first sequence of pictures has plural contiguous, non-overlapping segments, each of the plural segments having a single corresponding segment in each of the plural representations; decoding the latticed pictures of a first segment of the plural encoded representations; forming pictures by de-latticing the decoded latticed-pictures of the first segment; and displaying the de-latticed pictures of the first segment picture at a resolution corresponding to a picture resolution of 1/p, where p equals the number of plural segments.
