Technical Committee Meeting in Tokyo


HDTV and NGBS:


HDTV in the Mainstream


This year the HDTV Advisory Group report specially noted that HDTV had now gone mainstream, with almost all digital implementations carrying HDTV services. In addition it also noted that those in the process of moving to digital have strong plans to include HDTV services within their networks. This strong take up is due to reduced prices of MPEG4 encoding and decoding equipment and developments in standards like DVB-T2 which can now provide sufficient bandwidth to include multiple HD services. The main issue broadcasters now face is the lack of mainstream HDTV content, which requires facility upgrades and investment on new equipment and training. Many are moving towards fully fledged HDTV production facilities and should reach the required output in a few years time.


The newly formed NGBS (Next Generation Broadcasting Systems) Advisory Group looked at recent developments in the ‘NHK On-Demand’ service implementation, which has now over 400,000 active members. The platform offers catch-up as well as archive content on pay-per-view and subscription


bases. The report also looked at the updates to Super Hi- Vision including the development of the full resolution SHV camera using Dual-Green technology for image capture and recording. The development of integral 3DTV for viewing 3D without special glasses was also touched upon. The report further looked at recent 3DTV trials by KBS and the WebTV portal deployed by KBS.


TC Studies


Technical Committee carries out large number of studies on cutting edge technologies and technical issues of interest to the members of the ABU. Currently the studies are carried out in more than 45 projects covering broad areas of production, transmission, training and services, and spectrum issues. In addition, the Committee is assisted by the Digital Radio Forum, HD Advisory Group and the Next Generation Broadcasting Services Advisory Group in respect of digital radio developments, HD technology and new types of services expected to mature in the next few years.


In the Tokyo meeting, the results of the studies and the reports prepared by the respective project managers were


summarized and discussed. The reports ranged from subjects such as archiving, to file based production systems; mobile multimedia broadcasting to delivery on networks; online training methods to low cost infrastructure; and on spectrum issues of WRC-12 to spectrum issues specific to the ABU region. These reports form a substantial part of the work of the Committee and have been circulated among all the ABU members and


Out of these studies several important actions emerged including a TC Decision to send contributions to the upcoming ITU-CPM meeting, Recommendations on content protection measures and implementation of Emergency Warning Broadcasting Services.
