چکیده
We propose a scalable extension of the H.264/AVC video coding standard. To achieve an efficient scalable bit-stream representation of a video sequence, the temporal dependencies between pictures are exploited by using an open-loop subband approach. The related temporal analysis-synthesis filter bank structure is generalized to facilitate an adaptive block-based choice between the motion-compensated lifting representations of the Haar filter (uni-directional prediction) and the 5/3 filter (biprediction), both coupled with multiple-reference frame capabilities. Furthermore, an intra mode can be chosen on a block basis to efficiently represent blocks that cannot be reasonably predicted using motion compensation. As a remarkable feature of our approach, most components of H.264/AVC are used as specified in the standard, while only a few have been adjusted to the motion-compensated temporal filtering structure.

This document was written based on “very first draft” of MPEG-7 PPD (document N1923), and on some of the discussions in Fribourg and in the AHG. However, it is a personal contribution. For time reasons, we did not include the modifications to N1923 presented by Ibrahim Sezan, which synchronize it to other input documents. Modifications vs. N1923 are indicated through the Word versioning mechani...

The Moving Picture’s Experts Group (MPEG) has recently started work on a new standardization effort called the "Multimedia Content Description Interface," also known as MPEG-7. The goal of MPEG-7 is to enable fast and efficient searching and filtering of audio-visual material. The effort is being driven by specific requirements gleaned from a large number of applications related to image, video...
