TX interfaces includes BT1120/BT656 digital video interface, I2S audio interface and I2C conguration interface, which are all of industrial standard

design, allowing TX chip to use any standard interface for ISPs and audio chips on the market.

As for analog output, in addition to HDCVI format, the TX chip is also compatible with CVBS.

The TX chip supports 1280H@25fps/30fps/50fps/60fps and 1920H@25fps/30fps.

The RX chip supports HDCVI HD inputs and digital video outputs; I2S audio output, multiple-chip audio cascade output as well as I2C conguration

interface; it also supports exible mapping of HDCVI video input channel and digital output channel; each channel is of its own format and built-in

equalizer, supporting video parameters setup such as brightness, contrast, hue, saturation, dual-way control signal transmission.

The gure above shows the simplicity of HDCVI solution with TX chip adopted; its tiny size of the chip also makes itself quite suitable for the application

in all kinds of camera sizes.

As seen in Figure 2, RX chip has the same interface as AD chip in a conventional analog DVR, which is to say that it provides seamless integration with

conventional DVRs; and the built-in equalizer allows HDCVI DVR to receive HD video signal up to 500 meters. The TX chip supports

1280H@25fps/30fps/50fps/60fps and 1920H@25fps/30fps.

In a word, with minor changes done on conventional cameras and DVRs shall the manufacturers embrace a brand-new HDCVI solution, which levels

up image quality dramatically, but at a lower cost.
