PSCR System Tasks


Deliver Video
The deliver task includes the processing, storage, and transport functions. Sometimes the acquire and view tasks include the processing function’s encoding/decoding operations.

The demarcation between the acquire and deliver tasks can vary.

VQiPS: Deliver Video
In Example 1, the acquire task, or camera system, includes the encode operation, which is part of the processing function. In Example 2, the camera system does not include the encode operation.


In both examples, the view task, or play-back system, includes the decode operation, but other examples might instead include the decode operation in the deliver task and stream video to the view task.
