Enhanced Performance Video Coding
EPVC

Request for video test sequences for Enhanced Performance Video Coding work

(Approved by WP 3/16 on 10 July 2009 for immediate release)

Starting at the ITU-T SG16 meeting in Geneva of 28 January – 6 February 2009, it was concluded that Question 6/16 (Visual Coding) will increase its level of activity toward standardizing a next generation video coding technology and will move ahead toward issuing a request for proposals on the subject. The current Q6/16 working title of this project is "Enhanced Performance Video Coding" (EPVC).

Toward this goal, Q6/16 is currently developing an improved set of video test sequences for use in preparatory experiments, the evaluation of the responses to the request for proposals, and in the subsequent standardization work. This document is a request for submissions of such material to aid in the work.

The next generation of video coding technology is expected to address the application areas and requirements that are identified in the draft requirements document that is appended below.

Video test sequences suitable for testing and evaluating compression technology for the above application areas and requirements are being sought. These test sequences should exemplify typical video content found in the following scenarios

  1. HD Broadcast

    This scenario covers a wide variety of high quality content including news presentation, movies, and sports, and includes text / graphics mixed with natural video. The format should cover 720p and 1080p resolutions at commonly used frame rates from 23.976 to 60 frames per second. High frame rates are particularly desirable for sports material.

  2. HD Video Conferencing

    This scenario covers video conferencing with resolutions of 720p and higher at commonly used frame rates from 25 to 60 frames per second.

  3. Mobile Entertainment

    This scenario covers high quality video entertainment at resolutions suitable for mobile application with VGA (640x480) resolution at commonly used frame rates starting from 23.976 to 60 frames per second and/or QVGA resolutions at frame rates from 23.976 to 60 frames per second.

  4. Consumer Video Capture

    This scenario covers video captured with hand-held equipment and consumer-grade lenses and sensors at VGA (640x480) to 720p or 1080p resolution at commonly used frame rates from 23.976 to 60 frames per second.

  5. Ultra HD

    This scenario covers ultra high resolution content at resolutions of 3840x2160, 4096x2048, and higher at commonly used frame rates starting from 23.976 to 60 frames per second.

  6. Surveillance

    This scenario covers VGA, progressive SD (480p and 576p), and HD (720p and 1080p) at commonly used frame rates up to 60 frames per second.

The video test sequences should use progressive scan with at least 4:2:0 colour sampling and 8 bits per sample. Higher quality (4:4:4) colour sampling and greater bit depth (10 or 12 bits per sample) is desirable.

High quality video with low camera noise, high spatial frequency content and no "mezzanine" compression is highly desirable. The content of the video test sequences should preferably be challenging or difficult to encode.

An example of a usage rights statement suitable for Q6/16 purposes is as follows: "These sequences and all intellectual property rights therein remain the property of the XYZ Corporation. These sequences may be used and distributed for technology research, development, demonstration, and testing purposes. XYZ Corporation makes no warranties with respect to the sequences and expressly disclaims any warranties regarding their fitness for any purpose."

If desired, contributors may limit usage to be for purposes of developing, testing and promulgating technology standards.

Prospective contributors of test sequences should contact the following persons:

  • T.K. Tan, Q6/16 Test Set Coordinator (tktan.p@rd.nttdocomo.co.jp)
  • G.J. Sullivan, Q6/16 Rapporteur (gary.sullivan@ties.itu.int)
  • T. Wiegand, Q6/16 Associated Rapporteur (wiegand@hhi.de)
