Technical Review | January-March 2013
between the ITU Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG).
ITU-T H.265/HEVC has been designed to provide a flexible, reliable and robust solution, future-proofed to support the next decade of video, taking into account advancing screen resolutions. The standard is expected to be phased in as high-end products and services outgrow the limits of current network and display technology.
The ITU/ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC) will also continue to work on a range of extensions to HEVC, including support for 12-bit video as well as 4:2:2 and 4:4:4 chroma formats.
Further to that, another important element of this work will be the progression of HEVC towards scalable video coding. The three bodies will also work within the JCT on 3D-Video (JCT-3V), on the extension of HEVC towards stereoscopic and 3D video coding.
(APB) ATSC Begins Work On Next-GenTV
Advanced Television Standards Committee (ATSC) released its call for proposals for ATSC 3.0, the next-generation of broadcast television; a request that calls on broadcasters, consumer manufacturers and professional manufacturers to give their input on a new delivery method of real-time and non-real time television content and data to fixed and mobile devices. A document posted on the ATSC website includes an assessment of technical requirements, possible applications and a list of complete specification for fixed and mobile services using new broadcast signals. Interested parties need to send intent to respond to the CFP by Aug. 23 and submit their official response by Sept. 27. “The ATSC 3.0 Technology Group will develop voluntary technical standards and recommended practices for the next- generation digital terrestrial television broadcast system,” according to an excerpt from the document. “ATSC 3.0 is likely to be incompatible with current broadcast systems and therefore must provide improvements in performance, functionality and efficiency significant enough to warrant implementation of a non-backwards-compatible system. Interoperability with production systems and non-broadcast distribution systems should be considered.” (TV News Check)
The Philippines
The Philippines National Telecommunications Commission (NTC) has reportedly backed the adoption of the Japanese DTV standard to replace the analogue system in the country by 2015. According to the Commission, the NTC endorsed and recommended the adoption of Japan’s Integrated Service Digital Broadcasting-Terrestrial, or ISDB-T standard to the Department of Science and Technology (DOST) last December.
The DOST, which is in charge of big projects involving technology in the country, will make a final recommendation to Malacanang (Office of the President). If approved, the move would put the Philippines at odds with members of
the ASEAN grouping who have largely committed themselves to deploying DVB-T2 for the digital switchover.
ASEAN has agreed a timeframe of no later than 2020 to complete the switchover from analogue to digital broadcasting. Countries like Singapore, Malaysia and Thailand have already officially announced the ‘adoption of DVB-T2 as the DTV standard of choice.
In a joint media statement issued at last year’s ASEAN Ministers Responsible for Information and Second Conference of ASEAN Plus Three Ministers Responsible for Information conference, ASEAN ministers noted that “Digital Video Broadcasting – Terrestrial Second Generation (DVB-T2) is a more advanced technology compared to DVB-T and acknowledges the benefits of migrating directly to DVB-T2”.

Turkey Turkey Begins DVB-T2
Turkey has finally begun its migration from analogue to digital terrestrial TV with the publication of licensing guidelines by the broadcasting regulator, the Radio and Television Supreme Council (RTUK), the guidelines were published in December. The RTUK will evaluate all applications and will issue an ‘Eligibility Certificate’ only to those organisations that fulfill all criteria.
According to a previous announcement by the government, the country’s digital switchover process will be completed by June 2015. With most of Europe having already completed the transition to digital, its own policy has already made progress since being launched in 2006, with only a pilot project in Istanbul and Ankara having taken off.
The country is 800,000 square kilometres in area and most of this land is comprised of mountainous terrain, therefore 6,000 transmitter sites will be used to cover 90 per cent of the population. There will be eight multiplexes in total: one will be assigned to Turkish Radio and Television (TRT), one to local and regional broadcasters and six to the major national commercial broadcasters.
(Screendigest) Vietnam Vietnam to go to digital by 2020
Vietnam will completely switch from analogue to digital broadcasting by 2020 with five major cities – Hanoi, Ho Chi Minh City, Hai Phong, Da Nung and Can Tho – turning off all analogue signals by 2015. The remaining provinces are expected to complete the switchover by the end of 2020, as part of a nationwide scheme on digitising the transmission of TV signals. The government has specified that by 2015, 80 percent of households with TV sets should be able to view digital TV, with digital terrestrial TV serving up to 60 percent of the population.
