73rd Study Group Meeting on Quality Evaluation Method for Broadcasting
The 73rd Study Group Meeting on Quality Evaluation Method for Broadcasting was heldon 3 March 2016. Dr. Nishida, Chairman of this Study Group, reported that this SG
would be the end of the activity at the end of March 2016.
This Study Group was established in 1996 for researching the quality evaluation methodof program production and video and sound quality of transmission. In those days, westood at the dawn of the digital broadcasting and the dissemination of flat panel display
and larger screen size were advanced, so that establish of quality evaluation systems forthe display such as evaluation method, measurement methods and viewing environment
were desired.
Results of this SG were as follows.
(1) Reports
・Evaluation method of digital video program・Study of concrete evaluation examples for the subjective quality evaluation methodof IP/mobile service
・Research of monitoring and quality evaluation system for digital broadcasting・Experiment of SAMVIQ method
・Research and experiment result of the quality of flat display(2) Technical Reports
・Metadata to Monitor Errors of Video and Audio Signals on a Broadcasting Chain(ARIB TR-B29)
・Guidelines on quality control in real-time video transmission over IP networks for
program production and news gathering (ARIB TR-B34)(3) Test charts
・Reference evaluation images for High-vision system
・Ultra-high definition/wide-color-gamut standard test still images
・Ultra-high definition/wide-color-gamut standard test video images
Standard images are distributed from the Institute of Image Information and Television
Engineers, and are inflected widely in production companies, broadcasting companies andresearch organizations.
This SG contributed to creation of contribution draft of such ITU-R recommendation andreport in the activity of the International standardization activities.
Since then, bigger result would be expected by being active with the R&D Group of
Program Production Systems, so the SG of Quality Evaluation Method for Broadcasting,studying for 20 years, was decided to be the end of the activity.

(1) Video Program Production Systems
Survey results of the signal level of telop in HDR -TV broadcasting were reported to
the video coding technology working group.
Contribution of the color system conversion was drafted.
(2) Sound Program Production Systems
In response to the result of ITU-R SG6 held on July 2015, contributions of following 3
items were drafted.
・Channel allocation of the transmission system for sound program contribution
・Audio distribution and playback adapted to the listening environment
・Modification of the specification of channel base of advanced sound system
For the subjective sound quality evaluation method of the advanced sound system, it
was decided to cooperate with the creation of contribution.

Regarding the conversion of stereo program to monaural program, it was decided toconsider by adding to the TR-B30 (The Technology Guideline of Production for
Surround Broadcast Program).
(3) Interface between Program Production Equipment
The time code format of Interface between UHDTV studio equipment was confirmed.
Operation of the validity flag was the equivalent of SMPTE ST12-2, and chapter
configuration was revised as a final draft.
On the basis of summarizing of the mechanical specification of mount and electricalinterfaces, Technical Report of the Interconnection for UHDTV Camera and Lens was
discussed, and submitted to the 99th standard Assembly.
(4) Digital Closed caption Production
New ARIB standard of the exchange format of the digital closed caption file including
the conversion from digital subtitles to ARIB-TTML subtitles (recommended) was
discussed, and submitted to the 99th standard Assembly.
Base on the research result of each broadcasting station, program and page
management information were selected and drafted, then liaison was sent to the Next
Generation Television & Broadcasting Promotion Forum (NexTV-F), discussing theoperational guideline of advanced BS digital broadcasting.
Reflecting the results of liaison, program and page management information were
defined.
3 Transmission of Television Program Contribution(1) SNG Transmission System
To the provisions based on the experimental results, experiment conditions andexperimental items were studied with a view to revision of adding a DVB-S2X
standard to ARIB STD-B26 (HDTV digital SNG transmission systems).
For the indoor experiments, test items, test equipments and test place should bedetermined and plan to experiment in May 2016. The satellite communication
experiments are planning to study, including the possibility.
