Video over IP FEC Receiver v2.0 - XAPP1272 - How do I control packet requests if there is no Depacketizer in the system? What is the proper way to control the depack_req signal?

描述

In XAPP1272 the data pullout module is used to control packet requests for the Video Over IP FEC Receiver.

How do I control packet requests if there is no Depacketizer in the system?

What is the proper way to control the depack_req signal?

解决方案

The data pullout module only cares about the input signal depack_req.

In systems were there is no Depacketizer, the user can follow the below handshake method:

  1. The data pullout module sends a pkt_rdy to a dummy depacketizer
  2. The dummy depacketizer sends back one depack_req pulse to the data pullout module.
  3. The data pullout module passes this request to the Video Over IP FEC Receiver.
  4. The Video over IP FEC Receiver outputs one packet through the output axis interface.
  5. The dummy depacketizer sends another depack_req pulse to the data pullout module.
  6. Repeat these steps until all of the data has been pulled out of the Video Over IP FEC Receiver.
