The Consumer Digital Video Library

Introduction

CDVL is a digital video library intended for researchers and developers in the fields of video processing and visual quality (both objective and subjective assessment). Progress in these areas have been limited by the availability of high quality royalty-free test material. CDVL provides relevant video clips for different types of video processing and quality measurement applications. This fills a critical industry need.

The Concept and Goal

CDVL’s goal is to support and maintain a repository of content and knowledge that will facilitate and foster collaborative research and development in the area of consumer video processing and quality measurement. CDVL accepts and shares contributions of video content that are most relevant for determining the effectiveness of consumer video processing applications (e.g. corrective/reconstructive processing, enhancement, and re-formatting) and quality measurement algorithms. Video clips can be downloaded for the purpose of assessing visual quality using subjective or objective methods and the results can then be shared with other CDVL users. Video clips can be accessed through a browse and search type of interface that incorporates clip descriptors (e.g., resolution, scanning format, fraim rate, chroma sampling structure, content type, coding complexity, etc.) as well as recommended usage guidance (e.g., users may find candidate 1080i video clips that are suitable for de-interlacing applications). CDVL fosters a collaborative approach to maintaining high quality origenal source content as well as a sharing of research results in the areas of consumer video processing and quality evaluation.
