| 摘要 |
The invention is directed to a method and apparatus for providing temporal scaling frames for use in digital multimedia. The method involves using a removable unidirectional predicted temporal scaling frame communication alon g with intra-coded frames and/or inter-coded frames. The method involves the ability to selectively remove the temporal scaling frame(s) from being transmitted or decoded in order to satisfy, for example, power limits, data rate limits, computational limits or channel conditions. Examples presented include encoders, transcoders and decoders where the decision to drop the removable temporal scaling frames could be made. |
