What is HD-TVI?

HD-TVI means High Definition Transport Video Interface, It is a DSP-TVI technology developed by Techpoint(2012), and the Chipset was sold to Intersil , Chinese manufacture, such as Hikvision, HanBang, put this technology into their new product.

Hanbang successfully developed the TVI solution, solved HD-SDI's previous problems. TVI can convert the digital signals to analog ones, it extends the transmission distance, reduces the total cost, and takes less storage capacity, HD-TVI is also based on coaxial cable, support HD video signal (1080P/720P), Audio signal, digital signal transmission.

Why HD-TVI?

TVI comes from a US-based company that does not supply to only one manufacture, the chipset is open, not sealed, you can DIY your HD-TVI system with different brand. while HD-CVI, no matter camera or DVR, should be bought from original company or authorized company.
Customers like to match their DVR&Camera with different brand, because wide choice may mean more cost saving.
And the TVI price is close to 960H, people will like this kind of product.

HD-TVI vs HD-SDI

So in conclusion, the advantage of HD-TVI compared with HD-SDI is
● Longer transmission distance(without boost)
● Affordable Price
● Better Anti-interference and Reliability

HD-TVI vs IP Cam

So compared with IPC, the advantage of HD-TVI is
● No compression, so no video quality loss.
● Real-time video display, without any transmission signal delay.
● Low requirement for network bandwidth.

HD-TVI vs HD-CVI

Obviously, HD-TVI and HD-CVI have very similar features, both of them can provide analog high definition solutions. HD-TVI derives from American based company that does not supply to only one manufacturer. Therefore we are expecting many analog camera manufacturers will release wide range of HD-TVI based cameras to market. Therefore, HD-TVI is more likely to become an industry standard, not a proprietary technology/solution.
