What is the plug-in latency or delay introduced by SurCode for Dolby E Encoder?

Updated 3 weeks ago by Logan Sturgeon

Scope

SurCode for Dolby E introduces the same amount of frame delay that the hardware adds. Dolby E adds one video frame of delay upon encode and one video frame upon decode, which is comparable to the delay introduced by video encode and decode. For example, to go from a video data rate of 1.5 Gb/s to ~300 Mb/s, a Panasonic HD D5 VTR takes one video frame to encode and one video frame to decode. This is the same as Dolby E. Video coders running at 45 Mb/s have longer delays, so the Dolby E system needs to be configured so it can be buffered out appropriately.
