Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04N 11/02

US Classification:

3752401, 37524025

Abstract:

In one embodiment, a method that partitions a first sequence of pictures into plural representations, encodes each of the plural representations independently of each other with a common time base, provides a first portion of the plural encoded representations based on a first network condition, the first portion having a first bit-rate, and provides a second portion of the plural encoded representations 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.

US Classification:

37524025

Abstract:

In one embodiment, a method that includes receiving a single video stream, wherein the video stream includes plural processed representations of a single video signal, wherein each of the plural processed representations of the video signal (PPROTVS) includes a respective sequence of compressed latticed pictures, wherein each compressed latticed picture of each of the PPROTVS represents a corresponding respective picture of the video signal, wherein each respective picture of the video signal is represented by at most one compressed latticed picture from each of the PPROTVS, wherein corresponding segments of the PPROTVS are ordered and time shifted relative to each other to facilitate error concealment, the time-shift imposed by interspersing of non-corresponding segments between each of the corresponding segments; and providing error concealment on the received video stream.

International Classification:

H04N 7/12

US Classification:

37524013

Abstract:

Disclosed herein are certain embodiments of lattice video coding (LVC) systems and methods (collectively referred to herein also as LVC systems) that provide for adaptive streaming and/or burst error immunity in a video distribution network, such as the Internet or other communication networks. In general, as and explained further below, such LVC systems decompose or partition pictures of one or more segments (e. g. , groups of pictures or GOPs) of a video stream into N lattice representations (also referred to herein as latticed representations, latticed or latticed video representations, or the like), where each lattice representation comprises a subset of the pixels of the pre-partitioned picture, and where the collective lattice representations of a given picture comprises the same number of pixels as the pre-partitioned picture. Each resulting lattice representation corresponds to an independently decodable stream (or in some embodiments, dependently decodable streams) that is transmitted in such a manner as to enable dispersion of the corresponding data, hence resulting in temporal data elasticity and immunity to burst errors. Further, with regard to adaptive streaming, the decomposition of the original video into independently decodable streams of lattice representations enables fine-tuning of the bit rate without the necessity of signaling between a receiver and server while obviating the need for additional encoding hardware as is common in multi-bit rate stream implementations.
