IP Set Top Box

IP Set Top Box

Viewers formerly enjoyed watching video data transmitted through a broadband network on their television sets. However, the recent spread of mobile terminals allows users to also enjoy video data on their smartphones and tablets. This time, we would like to introduce our IP set-top box, which is indispensable for integrating this expanded system.

 

What is the IP Set-Top Box?

The IP set-top box is a receiving terminal for IPTV service that distributes video content to TVs through IP broadband network. Using an IP set-top box, users can enjoy general television programs, video on-demand (VOD), which allows users to select and watch various video contents when they want, and other cloud services such as community information, games and shopping.

While conventional IP set-top boxes offer a video service only to the TV connected to it as shown in the figure, we have provided IP set-top boxes with a home server function (*1) that enables video distribution to personal computers and tablets. Furthermore, we have developed a new IP set-top box that supports 4K (*2) video.

4K resolution has about 8.29 megapixels, which is about four times as many pixels as Full HD. This large number of pixels provides high-resolution, high-precision and high-quality images even on a large display. A frame rate of 60 frames per second, twice that of conventional TVs, is essential for displaying fast-moving video images such as sports broadcasting in such a high resolution.
