A meeting of the World Broadcasting Unions International Satellite Operations Group (WBU- ISOG) in Zagreb on 24-25 October passed a resolution honouring NHK for its work in the group.
The resolution read: “WBU- ISOG expresses its thanks and appreciation to NHK for the excellent work it does through the group in a range of important areas, and for its consistent support for broadcasting around the world.”
The group praised NHK for overseeing long-running MPEG-2 and MPEG- 4 interoperability tests among encoders from different manufacturers, which were recently completed successfully.
A series of MPEG-4 HD video encoder and decoder interoperability tests involving equipment from six vendors has recorded a 98 percent pass rate.
The tests were conducted over a five-day period in October for the World Broadcasting Unions International Satellite Operations Group, WBU- ISOG.

“It has consistently been ready to assume a leadership position in WBU-ISOG on behalf of the ABU, and it has always readily shared information about its newsgathering activities and its role in disaster early warning broadcasting,” the group said.
WBU-ISOG brings together members of the regional broadcasting unions, satellite operators and other broadcasting service providers to dis- cuss issues of common interest.
The Zagreb forum, chaired by Dick Tauber, CNN’s Vice-President, Transmis- sion Systems & New Tech- nology, attracted about 60 participants. Croatia’s national broadcaster, HRT, hosted the meeting.
A highlight was a pre- sentation by NHK on its coverage of the 11 March disaster.

Among the reasons were a lack of 3D content and

streams based on parameters set by WBU- ISOG. The transport streams were uploaded to a server and made available for downloading to all participants for internal vendor testing. Vendors then took their equipment to Telesat of Canada, which conducted formal tests.
A total of 588 video tests
were conducted on 121 MPEG-4 high definition transport streams in all four HD formats. Of these, 581 recorded an unconditional pass.
Five of the seven failures were due to a single decoder. Four of the six vendors recorded a 100- percent pass rate.

Her comment was echoed by Michel Chabron of Eutelsat, who said 3D TV was less popular now than a year ago, partly because of a lack of full 3D TV channels.
Eddy Frankland of Abu Dhabi-based satellite op- erator YahLive said that while there was some 3D TV in the Middle East, the main problems were lack of content and limited ac- cess to 3D TV sets.
Howard Fine of the Pacific Television Center said many viewers could not watch 3D TV for long without getting a headache or feeling uncomfortable.

“One of the reasons the tests turned out so well is because of the hard work the vendors did before the tests,” he told a WBU- ISOG Forum in Zagreb on 24-25 October.
A total of 112 audio interoperability tests were also conducted, in which 105 rated an unconditional pass.
