6.4.2Very low delay
6.4.2.1.1.1.1.1.1JCTVC-F147 Industry needs of very low delay coding [K. Kazui, A. Nakagawa, J. Koyama (Fujitsu)]
This was not a specific technology proposal; it was only an expression of desire for low latency support.
It was commented that a clear technical requirement was needed. For example, high frame rates (without excessive out-of-order encoding) can provide very low delay.
For example, area refresh with constrained intra prediction and constrained encoder MV search area and high frame rate – if implemented well – can basically do this.
It was commented that often, delay is a product implementation issue rather than a specification issue.
Further study is encouraged to see if there is some room for improvement.
