The exhibit concentrated on the capabilities of the RSCC orbital constellation. Visitors were particularly interested in coverage zones of RSCC’s Express-AM satellites, scheduled to be orbited next year at 14 deg. W, 40 deg. E, and 53 deg. E orbital slots.
The capacity of these satellites may be used to develop telecommunications networks and implement project in radio and telecasting, including HD TV, in Africa, Middle East, Europe, Latin America, and India.
A novelty item at IBC 2013 was the solutions based on Ultra HD technology.
The main technology trends on display were as follows:
The appearance of 4K (or Ultra HD) demonstrates the next phase of HD TV progress.
Full-frame 4K (4096 x 3112) outrivals a regular HD nearly four-fold at each side of the frame. Manufacturers of TV sets and cameras and related equipment have vigorously supported the development of 4К standard, while the emergence of HEVC compression standard helps resolve the issues of optimizing the use of communications channels.
Developed by ITU, HEVC is a new compression standard, using more efficient compression algorithms than was the case with H.264/MPEG-4 AVC. The macro-blocks used in H.264 are replaced in HEVC by blocks having tree-like encoding structure.
The advantage of a HEVC coder is in the use of large-size blocks.
Tests have proved that such blocks are more effective when encoding HD video, i.e. the use of a HEVC coder is efficient for encoding HD (and even more 4K). According to a number of assessments, HEVC encoding, on average, is up to 60% more efficient than MPEG-4. In other words, and encoded HD will need only 4Mbs versus 10 Mbs. The technology goes a long way towards cutting broadcasters’ costs, as well as those of TV channel producers and DTH operators using leased capacity.
Ultra HD gives TV viewers a chance to receive more high-detail visual information. The technology also gives an effect of volume to the picture.
Operator market participants are optimistic. They are counting on a growing demand for Ultra HD on the part of broadcasters in the nearest future.
