Error recovery and concealment at 10^(-3) BER

Started by Arvind Raman October 15, 2001
Hi all,
Well I had posted a message on the same topic a couple
of weeks ago and your messages were really helpful.
I am still carrying out experiments on Error recovery
and concealment at Bit Error Rates (BERs) of 10^(-4)
and 10^(-3). Though I could good pretty good results
at 10^(-4) with just a data partitioned bitstream
(without using RVLC), it doesn't really work well at
BERs as high as 10^(-3). I feel that the packet size
(at a certain bitrate) could play a crucial role in
deciding how good the algorithm works at such high
BERs.
I would thus like to know

1. What would be an ideal packet size to use, at BERs
as high as 10^(-3) for 64 kbps

2. Is it possible to error conceal a 10^(-3) BER
affeted bitstream so as to get no visual degradation.
If so, is it possible only thru the use of RVLCs.

Thanks a lot for your time and help.

regards
Arvind Raman



Hi,

Can anybody help me get the sample bitstreams for the
MPEG-4 video decoder (Simple profile only). Please
tell me the site wherefrom i can download the sample
bitstreams.
