Modular Media over IP ST2022-56 Packetizer v.1.0 (Rev. 2) - The IP core does not add null octets for partially filled packets of the last datagram of the video frame contrary to the SMPTE 6 specification

描述

The SMPTE 6 specification SMPTE ST 2022-6:2012 Page 6 states the following about the last datagram of the Video Frame:.

"The last datagram of the video frame, being only partially filled with luminance and color-difference values, shall have additional null octets added to achieve a total length of 1376 octets"

However the Modular Media over IP ST2022-56 Packetizer does not follow this in example design simulation and also when it is checked in hardware from the Wireshark logs.

解决方案

This is a known issue in the Vivado 2016.3 Modular Media over IP ST2022-56 Packetizer v.1.0 (Rev. 2).

This issue is resolved in Vivado 2016.4 Modular Media over IP ST2022-56 Packetizer v.1.0 (Rev. 3).
