  Changing the DVEVM Memory Map
  PDF, 1.2 Мб, Файл опубликован: 26 сен 2007
  This document describes how to configure Codec Engine-based audio/video applications on the DM6446 (DaVinci) for use in a system that has less than the 256 MB of DDR2 memory that the evaluation board provides. Specifically, we present steps for shrinking memory requirements down to 64 MB, but the principles apply to any amount of DDR2.

  Measuring Video Quality With the TMS320DM6446 DVSDK
  PDF, 136 Кб, Файл опубликован: 8 май 2007
  The transmission of video sequences is enabled by compressing the video content with different video encoding algorithms at the source and decoding the stream at the destination. The compression process discards part of the original information and decreases the video quality of the decoded stream.Measuring the video quality is measuring how close the decoded stream is to the original stream.

  De-Interlacing and YUV 4:2:2 to 4:2:0 Conversion on DM6446 Using the Resizer (Rev. B)
  PDF, 186 Кб, Версия: B, Файл опубликован: 17 дек 2008
  Video signals captured directly from charge-coupled device (CCD) cameras naturally have interlaced effects and are in a 4:2:2 interleaved format. They typically need to be converted to a 4:2:0 planar format before being encoded because most video compression standards accept input only in 4:2:0 format. It is better to reduce or remove the interlaced artifacts in the original video signal when fe
