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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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)
