According to a report from IHS research, the information produced by all the video surveillance cameras (1080p @30fps) installed worldwide in 2013 alone was equal to 413 Petabytes (PB), which is enough to fill 92.1 million single-sided, single layer DVDs. With shipments of such surveillance cameras continuing to rise, analysts expect that the daily data dump is expected to more than double that in just four years, expanding to around 859 PB in 2017. The researchers predict that the overwhelming quantity of information will promote the use of technologies that are designed to handle and process big data in the surveillance market.

“Fulfilling this requirement generates huge volumes of image pixels continuously, for transmission and storage, thus creating demand for a very broad bandwidth and tremendous memory space resources,” states H.Y. Lin, President of ITE Tech."Recognising these trends and issues in advance, we, ITE, have launched the ccHDtv technology and formed the Alliance in January 2015 with nine allied partners."

To deal with the enormous volume of video signal transmission, ITE's ccHDtv technology is believed to be a world first technique to carry video signals from multiple channels and transmit them concurrently, whilst typical IP systems on the market are transmitting video signals in sequence.

The multi-channel video signal transmission is the specification of ccHDtv, developed by ITE.  By utilising the Frequency Division multiplexing techniques based on DTV broadcasting transmission techniques, which are compliant with EN300 744 DVB-T modulation and demodulation standards used worldwide by digital television broadcasters, ccHDtv transmission will efficiently carry single and/or multiple 1080p @60fps digital video signals over a single 5C2V/RG6 coaxial cable for a distance of up to 1000 metres. During a live field test conducted by ITE and at the sites of its allied partners, the results showed no interference problems in HD video transmission (even up to 4K resolution) and no signal amplifier or booster was required within the above specified distance.

“It’s fairly clear that the ccHDtv solutions perform with higher efficiency and at a quicker response rate in comparison with the other market options.” Emphasised by Stanley Wang, VP of ITE Tech Inc. and the Head of the ccHDtv Alliance, "With the ccHDtv Alliance, ITE will support our allied companies in showcasing the latest DTV solutions on a dedicated stand at IFSEC International 2015 on June 16-18 in London, UK."

ITE Tech invites more Surveillance industrial manufacturers and vendors to visit and join the ccHDtv Alliance. The full story about ccHDtv technology is revealed in the curent issue of Detektor International which will be availble at the Ifsec exhibition in London next month.
