Using multiple transform/subband representations for video encoding |
摘要 |
A method of encoding a sequence of video frames, comprising receiving a sequence of video frames, encoding at least a first portion of the sequence of frames using the first type of transform/subband representation to produce first transform/subband coefficients, encoding at least a second portion of the sequence of frames using the second type of transform/subband representation to produce second transform/subband coefficients; and providing the first and second transform/subband coefficients at an output. |

1. A method of encoding a sequence of video frames using an encoder, comprising:
receiving a sequence of video frames; encoding at least a first portion of the sequence of frames using a first type of transform/subband representation to produce first transform/subband coefficients; encoding at least a second portion of the sequence of frames, different from the first portion of the sequence of frames, using a second type of transform/subband representation to produce second transform/subband coefficients, wherein the second type of transform/subband representation is different from the first type of transform/subband representation, and wherein the first type and second type of transform/subband representation are used for encoding within a first region and within a second region, respectively, of the same frame, so that the type of transform/subband representation differs from region to region within the same frame; and providing the first and second transform/subband coefficients at an output. |
