Error recovery and concealment at 10^(-3) BER - Arvind Raman - Oct 15 13:05:00 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. mohit |
