Wireless receiver for receiving multi-contents file and method for outputting data using the same
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 control operation so that a result of the analysis is inputted into the decoder or OSD processor. A memory stores the stream and control program data.
1. A wireless receiver for receiving a multi-contents file, the wireless receiver, comprising:
a video decoder for decoding a video stream;
an audio decoder for decoding an audio contents file;
an on-screen display (OSD) processor for processing a text file and additional information;
a video output unit for selectively configuring decoded video data and text data on one screen and performing encoding and outputting operations on the basis of a format of a display unit;
an audio output unit for outputting decoded audio data;
a user interface for receiving a user's command;
a controller;
a wireless local area network (WLAN) device for transmitting data between a computer system and the controller; and
a memory coupled to the controller for storing the transmitted data and a control program data,
wherein the computer system comprises data, the data comprising a navigation screen, a contents file, and additional information of the contents file edited and processed by the computer system;
wherein the contents file comprises at least one of an audio contents file, a video contents file, an image contents file, and a text contents file;
wherein the controller is configured to request transmission of the data via the WLAN device from the computer system in response to the user's command, is further configured to analyze the transmitted data, and is further configured to input the analyzed data into at least one of the audio decoder, the video decoder, and the OSD processor; and
wherein the additional information of the contents file comprises at least one of a representative image corresponding to each contents file and annotation information describing each contents file.
2. The wireless receiver of claim 1 , wherein the user interface comprises a remote control signal receiver for receiving a signal from a remote control.
3. The wireless receiver of claim 1 , wherein the data is encoded and transmitted in a MPEG2 I-frame format and decoded by at least one of the audio decoder, the video decoder, and the OSD processor.
4. A method for communicating a multi-contents file, comprising the steps of:
transmitting a user request for data from a controller to a computer system via a wireless local area network (WLAN), wherein the data comprises a navigation screen, at least one contents file, and additional information of the contents file edited and processed by the computer system;
wherein the contents file comprises at least one of an audio contents file, a video contents file, an image contents file, and a text contents file;
wherein the additional information of the contents file comprises at least one of a representative image corresponding to each contents file and annotation information describing each contents file;
receiving the transmitted data from the computer system via the WLAN;
decoding the transmitted data;
outputting the decoded data to an audio/visual system;
transmitting a subsequent user request for subsequent data from the controller to the computer system via the WLAN, wherein the subsequent data comprises at least one of a navigation screen, at least one contents file, a file of list information corresponding to each title configure the navigation screen, and additional information for the at least one contents file edited and processed by the computer system;
performing a decoding or on-screen display (OSD) processing operation for the transmitted subsequent data; and
outputting the decoded or processed data to the audio/visual system.
5. The method of claim 4 , further comprising the steps of:
encoding and transmitting the data in a MPEG2 I-frame format; and
decoding the data with at least one of the audio decoder, the video decoder, and the OSD processor.
