Jia haosheng: hd-tvi of analog HD solution

JoeQiu, sales director of TVT digital technologies, said in an interview with media that about 100m coaxial cables have been deployed around the world to connect analog cameras. They will all be replaced by high-definition cameras in the next three to five years. However, some users are also starting to worry that they will have to rewire, install, and add additional network equipment, and they would prefer to upgrade to hd with an economical and easy-to-install solution rather than using IP cameras directly. In this context, hd-sdi and TVI technologies came into being.

Hd-tvi is the coaxial HD video transmission standard, which is a coaxial cable based HD video transmission specification. As a new analog HD solution, whether it can make up for the current defects of analog HD in the market, follow the small series to see.

Technical advantages of hd-tvi

In the current analog HD solutions, transmission distance, compatibility and cost have been the problems that have troubled many manufacturers and users. In this context, many insiders are also paying attention to the new hd-tvi technology to solve the limitations of previous analog HD solutions.

Recently, TVT has introduced a new hd-over-coaxial solution. The company claims that its technology has successfully addressed the limitations of hd-sdi, providing a more economical and easy to install and use solution.

TVI, which converts digital signals into analogies, will extend transmission distances, reduce total costs and require less storage. Its transmission distance through coaxial cable can reach 300~500 meters. In addition, TVI can transmit CVBS75 ohm analog signals, as well as 30fps 1,080p and 720P transmission, which are difficult to do with other hd coaxial solutions. Users can even replace their analog cameras and DVRS with TVI cameras and DVRS and get a new 1080P system without any additional knowledge or extra labor costs.

Regarding the compatibility and usability of new technologies, Qiu, sales director of TVT, illustrates the overall advantages that TVI can bring:

First, TVI comes from an American company that supplies chipsets to many manufacturers around the world, so all future customers will be free to choose the manufacturer they want in the supply chain TVI covers around the world. This also means that TVI is likely to become an industry standard in the future, rather than just a proprietary technology or solution.

As an open solution, TVI is a future-oriented technology with high compatibility and interoperability with other products. For example, TVIDVR is compatible with 720P and 1080P cameras from several other brands. This will provide TVT customers with many advantages, particularly in reducing inventory. TVT will provide cost-effective solutions for the low - and mid-end markets using coaxial cables; By contrast, hd-sdi is targeting the high end of the market.

TVT believes Asia will be the first market to adopt the technology. In Asia, volatile bandwidth is still a headache for integrators trying to build reliable IP systems. On the other hand, there are still many people who lack sufficient IP knowledge. These two factors have hindered the spread of IP systems in Asia. As a result, Qiu believes that about 50 per cent of installers in Asia are more interested in finding solutions that are as easy to use as TVI. Because TVI has great commercial potential, TVT is committed to developing a more complete TVI product range. The company has developed 4/8 and 16-channel DVRS and cameras for high-ball and box-type cameras at prices ranging from high, mid-range to entry-level, with 1080P and 720P resolution.

Whether customers may need a whole new system, or only need to retrofit part of a project, it is almost impossible for them to completely abandon the existing simulation system or coaxial cable. Therefore, "as a total solution provider, our goal is to provide customers with a variety of products and methods to move to full IP, including integrating IP/ hd-sdi and TVI products to provide more practical and cost-effective solutions," he stressed. TVT has also set up a centre for smart home products aimed at SOHO, small and medium-sized enterprises and residential users, with the first product expected in the second half of this year.
