| 摘要 |
The present invention relates to an apparatus for predictively encoding a sequence of signal frames to obtain a sequence of encoded frames, the apparatus comprising a prediction encoder (101) for providing the sequence of encoded frames from the sequence of signal frames, the prediction encoder (101) being configured for providing a k -th encoded frame from a k-th signal frame and from a reference frame for the k-th signal frame, a reception unit (111) configured for receiving frame information indicating a minimum number of frames or a certain number of frames which are to separate the k-th signal frame and the reference frame, and a controller (113) configured for determining a frame number N from the frame information, wherein the prediction encoder (101) is configured for selecting a signal frame spaced apart by N frames from the k-th signal frame in the sequence of signal frames as the reference frame for the k-th signal frame. |
