摘要： A system and method for efficiently upsampling and filtering a signal is provided. The system includes a controller 216 and an upsampler 202 capable of upsampling a digitized signal. The upsampler 202 converts a digitized signal having a first sampled frequency into a digitized signal having a second sampled frequency by inserting, for example, at least one zero between the samples of the digitized signal. A plurality of filters 205-208 is coupled to the upsampler. These filters, which may be band-pass filters, would be suitable for front end encoding in audio-based applications. The controller 216 adjusts at least one output of the plurality of the filters to zero, either by deactivation or forcing the filter to zero, based upon a predetermined characteristic of the digitized signal. One example of a predetermined characteristic is a maximum frequency of interest.

摘要： A system and a method perform frame interpolation for a compressed video bitstream. The system and the method may combine candidate pictures to generate an interpolated video picture inserted between two original video pictures. The system and the method may generate the candidate pictures from different motion fields. The candidate pictures may be generated partially or wholly from motion vectors extracted from the compressed video bitstream. The system and the method may reduce computation required for interpolation of video frames without a negative impact on visual quality of a video sequence.
摘要翻译：系统和方法对压缩视频比特流执行帧内插。系统和方法可以组合候选图片以产生插入在两个原始视频图像之间的内插视频图像。该系统和方法可以从不同的运动场产生候选图像。候选图片可以部分地或全部地从压缩视频比特流中提取的运动矢量生成。系统和方法可以减少对视频帧的插值所需的计算，而不会对视频序列的视觉质量产生负面影响。
