The master interface reads several types of video data from external memory:
- Bitstream
- Reference frame pixels
- Co-located picture motion vectors
- Headers and residual data
- Various tables (weighted prediction, scaling lists, POC lists)
The master interface writes:
- Decoded frame pixels
- Headers and residual data
- Decoded frame motion vectors, when the picture is later used as co-located picture
- Reconstructed frame pixel data (with optional secondary raster output)
