Even during one of the worst global recessions in the history, technologies and markets for the wireless HD video distribution (HDVD ) inside of a home continue to attract attention of R&D and the industry. There are several factors for this:
It is a very lucrative area, with a potential customers size in many hundred of millions
The majority of cable, satellite and telephone companies offer HD video
Wired connections are becoming more and more complicated and inefficient due to proliferation home theaters with multiple HD-ready devices, such as TV sets, video projectors, various players and other
Progress in the IC, packaging and other technologies allows constructing relatively inexpensive high-quality HDVD radios.
This report addresses multiple radio technologies that are developing to serve the HD video distribution market for short-range wireless transmission. It also compares these technologies features and market properties. The main goal is to show the dynamics of the marketplace and properties of various technologies that support this very active market.
The report, in particular, addresses following markets and technologies:
WirelessHD: 60 GHz technology developed by SiBeam, now with many partners. Standard produced by the WirelessHD Alliance.
WPAN-IEEE 802.15.3c
WHDI (Wireless Home Digital Interface): 5 GHz technology developed by Amimon. Standard produced by WHDI Special Interest Group (SIG), which consist of several leading companies in the CE and communications industries.
A UWB-based technology developed by Sigma Designs
WiGig- a recently established group, which was founded by leading manufacturers in CE and communications.
IEEE 802.11n
ECMA-387
Very High Throughput Group-IEEE 802.11ad.
Most of these technologies were designed to carry uncompressed video signals. The most developed technology is IEEE802.11n with already established industry and price efficiency; though this technology was not designed for multi-gigabits transmission required for uncompressed HD video distribution. Authors believes that the number of competing technologies may increase, with 802.11n prevailing before uncompressed wireless HD video distribution technologies mature. International efforts (ECMA and ISO) may lead to the establishing an international standard.
