Abstract
This paper considers the problem of improving the QoS of MPEG 2 video transmission over ADSL, which is an emerging technology that permits high bit rate transmission over subscriber lines. For this purpose, we propose to combine the use of the DP (Data Partitioning) MPEG 2 scalable mode and a modified coded DMT based ADSL modem that provides two different Bit Error Rates (BERs) for transmission: important video data such as headers and synchronization modules are better protected than less important data, resulting in a QoS improvement.
