Why did you add a high-speed bidirectional communication function to the AV interface?

Yum: It is to construct a home network among appliances connected to one another with DIVA cables. In the past, to construct a home network, we had to connect home appliances by using Ethernet cables or wireless LAN in addition to HDMI cables. With the DIVA, all we have to do is to connect appliances with cables.

For example, by using a TV set as a hub and connecting it to an STB, recorder, game console, PC and so forth with DIVA cables, it is possible to enable them to mutually communicate with, send AV data to and operate one another. Also, it will be easier to get connected to the Internet, and DLNA can be used on the DIVA network.

The HDMI is already seen as the industry's de facto standard. What kind of strategies do you have to compete with the HDMI?

Yum: Our aim is not to compete directly against any particular standard. Our aim is to create a new home audio/video networking standard. We are in cooperation with major consumer-electronics makers in China. In digital equipment in China, analog interfaces are still used to transmit HDTV videos. So, the HDMI has not become widely used yet. In addition, China is trying to establish its own specification. So, we aim to have the DIVA selected as China's own specification for a start.

We like to finalize the specification by the end of 2008 and ship transmitter and receiver chip sets in 2009 or 2010. Also, we have a plan to develop a bridge LSI that can interconvert DIVA signals and HDMI signals.

Correction Notice: We changed the title of the article and part of the second-to-last paragraph because they turned out to be misleading.
