Abstract
After more than 20 years, several video coding standards and technologies have been delivered. Less consideration is taken on their commonalities and interoperations. Specification and reference code of case by case is time consuming. The MPEG reconfigurable video coding (RVC) framework is a new standard under development by MPEG. It aims to provide a unified high‐level specification of current MPEG video coding technologies. In this framework, the decoder is built as a configuration of video coding tools taken from MPEG toolbox library. Up to now, MPEG‐4 simple profile and China audio video coding standard (AVS) decoders have been successfully modeled with RVC framework. In this paper, we examine another video standard, that is, DV/DVCPRO, and model it with RVC‐CAL. The flexibility and ease of RVC‐CAL is demonstrated as well as the validation of RVC modeling.
Highlights
Video coding solutions based on a predefined video coding standard have certain limitations when new standards are being added
We model the other video coding standard, Digital video (DV)/DVCPRO, using the reconfigurable video coding (RVC) framework
The experimental result illustrates the advantages of using MPEG RVC as a new video coding standard
Summary
Video coding solutions based on a predefined video coding standard have certain limitations when new standards are being added. It is preferred to develop a framework to operate at a higher level of abstraction and simplify top-down system development and design To deal with this issue, MPEG organization launched a new standard called reconfigurable video coding (RVC) in 2006 [1]. We model the other video coding standard, DV/DVCPRO, using the RVC framework. Two standards [7, 8] define the data structure for the interface of DV-based digital audio, subcode data, and compressed video at different bit rates: the DV standard includes both 525/60 and 625/50 systems, in which the numeric values “525” and “625” refer to the number of the horizontal sync lines while the numeric values “60” and “50” indicate the field rate. In the 1080-line system, video data, audio data, and subcode data in one video frame are processed
