What's HD-TVI?

HD-TVI means High Definition Transport Video Interface, It is a DSP-TVI technology developed by Techpoint, and the Chipset was sold to Intersil , Chinese manufacture, such as Hikvision, HanBang, put this technology into their new product.

Security camera companies Dahua, Hikvision in the transfer of HD-image through a coaxial cable takes an interesting turn. HDCVI - in house technology of Dahua, however, Hikvision, as it turned out, gets HDTVI standard chips on the side.

Real developer standard of HDTVI is California company Techpoint. The company was established three years ago by the former top management of a major producer of electronic components Techwell after selling the last concern Intersil. According Techpoint, transmission standard for digital video coax HD-SDI was developed by experts it was her, but later found a number of technical and commercial obstacles to its implementation. In parallel, HD-SDI engineers developed a solution for analog and HD-video transmission. Noting the past two years, a growing interest in high-definition analog TV guide Techpoint decided to start promoting the new standard HD-TVI (High Definition Transport Video Interface).

That company produces Techpoint transmitting and receiving units for broadcasting video over coax standard HD-TVI. The parameters of the transmitted signal - resolution up to Full HD 1080p, frame rate up to 30fps, transmission distance up to 500 meters of coaxial cable type 75-ohm 3C-2V. There's also a two-way transmission of control signals. Chipset HD-TVI, as reported on the website of the manufacturer supplied more than one hundred companies, including Hikvision, TVT, AVTech, IDIS "And many others." Perhaps the "others" is simply cautious without being fully confident that the new standard has a reasonable market prospects.
