Abstract
A wireless receiver for receiving a multi-contents file and a method for outputting data using the same, which can receive, navigation information for providing intuitively recognizable search interfaces to a user by radio in real time, receive various types of contents files by radio in real time, and output the received information and files through an AV device. A video decoder decodes a video stream on the basis of an MPEG standard. An audio decoder decodes an audio contents file. An OSD processor processes a text file and additional information. A video output unit selectively configures decoded video data and text data on one screen and performs encoding and outputting operations based on the format of a display unit. An audio output unit outputs decoded audio data. A user interface receives a user's command. A WLAN card communicates WLAN data with a computer system. A controller requests the computer system to transmit navigation screen information, at least one contents file or additional information of the contents file edited and processed by the computer system, analyzes a data stream received by radio from the computer system responsive to the request, and performs a co…
