Multi-mode error concealment, recovery and resilience coding

摘要

Multi-mode error concealment, recovery and resilience coding. Adaptation of a number of coding units (CUs) employed in accordance with video coding may be made as a function of error. As a number of errors increases, the respective number of CUs may correspondingly increase (e.g., which may be made in accompaniment with a reduction of CU size). As a number of errors decreases, the respective number of CUs may correspondingly decrease (e.g., which may be made in accompaniment with an increase of CU size). Such errors may be associated with a type of source providing a video signal, a type of error resilience coding employed, communication link and/or channel conditions, a remote error characteristic (e.g., such as associated with a source device and/or destination device), a local error characteristic (e.g., such as associated with operations and/or processing within a given device), and/or any other type of consideration.

主权项

1. A communication device comprising:
a communication interface configured to:
receive, via a first communication channel, a first video signal from a first other communication device; andoutput, via a second communication channel, a second video signal to a second other communication device; and a processor configured to:
process first slices of the first video signal based on first coding unit (CU) size to generate a first portion of the second video signal;select a second CU size that is different than the first CU size based on error associated with the second communication channel; andprocess second slices of the first video signal based on the second CU size to generate a second portion of the second video signal that is subsequent to the first portion of the second video signal.
