TL;DR: In this article, a method for enhancing the picture quality of a video signal is proposed, which comprises the steps of receiving an encoded video signal having a plurality of headers, maintaining a plurality codebooks based upon the differences between a standard definition picture and a high definition picture, and providing a pointer to a particular codebook of the plurality of codebooks when decoding a frame of the video signal.

TL;DR: In this article, an algorithm based on motion compensation uses a temporal support of five fields of video to produce a progressive frame, where the moving average of the motion compensated field lines temporally adjacent to the field to be de-interlaced are used, after a non-linear filtering, as the missing lines to complete the progressive video frame.

TL;DR: In this article, a method of enhancing picture quality of a video signal is proposed, which comprises the steps of receiving base layer images of standard definition pictures from a base layer decoder, defining image areas of the SDP pictures, classifying image areas into image types by assigning a class number, and generating enhanced pictures based upon the standard definition picture and the classification of the image areas.

TL;DR: In this article, a method of enhancing picture quality of a video signal is described, comprising steps of receiving base images for pictrues having a first definition from a base layer decoder, coding the differences between the base images of pictures and pictures having a second definition using vector quantization, creating a database of codebooks based upon the differences, and generating enhanced images based upon base images and enhancement stream data.
