The A/V buffer manager manages audio/video data from memory and from the PL layer. Data from memory is considered non-live and data from the PL is considered live. Data from memory is written into channel buffers using the AXI4 stream interface. The maximum burst allowed is 256 bytes for video channels and 64 bytes on audio channels.
The DisplayPort controller is capable of presenting the following.
•Live video/audio stream
•A mix/blend of live and non-live video/audio
