ERROR FILTER TO DIFFERENTIATE BETWEEN REVERSE LINK AND FORWARD LINK VIDEO DATA ERRORS
First Claim
1. A method comprising:
- receiving an indication of a video data error detected by a video decoder;
determining whether the video data error occurred on a reverse link of a wireless network between a video encoder and a network device; and
applying error control in response to indication of the video data error if the video data error did not occur on the reverse link and not applying error control in response to the video data error if the video data error occurred on the reverse link.

Abstract
One technique for implementing error control in response to a video data error comprises receiving an indication of a video data error from a video decoder, determining whether the video data error occurred on a reverse link of a wireless network between a video encoder and a network device, and applying error control in response to the video data error if the video data error did not occur on the reverse link. For example, the indication of the video data error may include a first sequence number (SN) of a packet comprising lost data, and determining whether the video data error occurred on the reverse link may include comparing first SN with a second SN of a packet associated with a most recent RL error.

18. A system comprising:
-
a transceiver to receive an indication of a video data error detected by a video decoder; a video encoder; and an error filter to determine whether the video data error occurred on a reverse link of a wireless network between the video encoder and a network device, wherein the video encoder is configured to apply error control in response to the indication of the video data error if the video data error did not occur on the reverse link. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
