Project will deliver highly resilient wireless transmission of video
for professional and consumer applications
Bristol, UK -- Wireless video specialists ProVision Communications
have been awarded a major grant by the DTI (the UK's Department of
Trade & Industry) towards the development of technology for the
wireless transmission of high quality video. The project will bring
together ProVision's strengths in MIMO wireless and H.264/ MPEG4
video compression to deliver systems providing highly resilient
wireless transmission of full broadcast quality video. The new
technology is being developed to meet the increasing demand for
wireless equipment that can deliver high quality video reliably in
real time, for applications ranging from broadcast TV production
down to consumer set top boxes. |

Modern wireless
standards do not interoperate efficiently with today's video
compression standards, since they have been developed largely in
isolation from each other. Wireless standards have been optimised
for asynchronous data transfer, while video standards have been
optimised for compression in a way that makes real time video very
sensitive to the sorts of errors that inevitably occur in wireless
transmission. Buffering the signal to allow for error correction can
help correct this, but leads to unacceptable delays in the resulting
video. New approaches are therefore required if applications which
require 'real time' video, such as television production, are to
integrate wireless based equipment alongside their traditional wired
systems. The team at ProVision Communications has many years of
experience in MIMO technology and video compression. The six figure
development grant from the DTI will enable ProVision to apply MIMO
to the wireless transmission of full broadcast quality video, and to
develop the next generation of wireless equipment.
"This grant is a strong endorsement of our reputation as leaders in
wireless video technology," said Professor David Bull, Director of
Video Technology at ProVision Communications, "The world is rapidly
moving over to wireless solutions for many applications - both
professional and consumer - yet delivering high quality video
reliably in real time over wireless links is still an extremely
challenging problem. Very few companies in the world have the
ability to tackle this: ProVision is one of them, and the grant by
the DTI recognises this. The technology that we are developing will
provide significant benefits across the spectrum of applications,
ranging from wireless cameras for broadcasters down to reliable
video distribution in the home."
About MIMO
MIMO stands for 'Multiple In Multiple Out' wireless antenna
technology, and makes use of multiple antenna elements at both the
transmitter and receiver. ProVision Communications has a strong
background in this field. It was among the very first companies to
produce a real-time MIMO demonstration system, back in 2003; the
system provided real-time transport of MPEG-2 video using a 2
transmit antenna 2 receive antenna configuration. ProVision's focus
on MIMO lies in the development of low complexity and robust
implementations that enhance bandwidth efficiency without the need
for greater transmit power, thus offering higher throughputs without
the need for additional bandwidth.
