ARIB data-broadcasting browser

Mitsubishi Electric Corp.

Not decided yet (but, under positive consideration)

With the extension we have made, DirectFB well supports AVG requirements of the ARIB data-broadcasting, such as composition of multiple graphics planes and video plane.

Because DirectFB itself already supports MHP, this extended window system is globally applicable to CE devices like DTV/STB/DVD as their software platform.

A prototype of ARIB data-broadcasting browser is built on DirectFB with extension. It presents reproduced images of data-broadcast multimedia contents,

composed of a video, still pictures, texts and graphics.

Demo: x86 (Pentium) possibly any hardware
