Abstract

A media device and controlling method thereof are disclosed, by which consumer electronics control (CEC) support information is provided. The present invention includes a storage unit for storing E-EDID including information indicating whether the media sink device supports CEC, an interface unit corresponding to a data transceiving path between the media source device and the media sink device, and a control unit connected to the media source device to send the E-EDID including the CEC support information to the connected media source device via the interface unit.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0116425 filed on November 23, 2006, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a media device and a control method thereof, more particularly to a media sink device, a media source device and their control method. Although the present invention is suitable for a wide range of applications, it is particularly suitable for providing consumer electronic control (hereinafter abbreviated as CEC) support information. Background technique [0003] Usually, a media source device (such as a set-top box (STB) for regenerating and processing prescribed media data) and a media source device for outputting media provided by the media source device are connected through a prescribed media interface. Data media sink devices (for example, digital television (DTV) for short hereinafter) are connected together. In this case, the ...
