INCLUSION OF SWITCHED INTERPOLATION FILTER COEFFICIENTS IN A COMPRESSED BIT-STREAM |
摘要 |
In one example, an encoder may apply a plurality of pre-defined interpolation filters to units of video data, such as frames of reference video, in order to generate a plurality of different interpolated prediction data. The encoder may also at times determine that a new interpolation filter or set of interpolation filters might improve coding quality by either improving video compression or improving reconstructed image quality. The encoder may also signal to a video decoder whether one of the pre-defined interpolation filters was used or a new set of interpolation filters was used. The encoder may also signal to a video decoder whether to continue using the new set of interpolation filters, or whether to revert back to using the pre-defined set of interpolation filters. A video decoder can decode video data based on data received from the video encoder. |
