Abstract

A method and apparatus for transmitting and receiving graphical data are provided. The apparatus for transmitting includes a graphical data generating unit that generates graphical data; an encoder that converts the graphical data into a JPEG 2000 code stream; and a transmitting unit that transmits video streams and the code stream. The apparatus for receiving includes a receiving unit that extracts an JPEG 2000 code stream; a decoder that decodes the code stream; and a display unit that displays a video stream included in the received stream and the decoded code stream. The method for transmitting the graphical data includes generating graphical data; converting the data into a JPEG 2000 code stream; and transmitting video streams and the JPEG 2000 code stream. The method for receiving the graphical data includes extracting a JPEG 2000 code stream; decoding the code stream; and displaying the decoded code stream and a video stream.

Claims

exact text as granted — not AI-modified
1 . An apparatus for transmitting graphical data, the apparatus comprising:
 a graphical data generating unit that generates graphical data;   an encoder that converts the graphical data into a JPEG 2000 code stream; and   a transmitting unit that transmits video streams and the JPEG 2000 code stream.   
     
     
         2 . The apparatus of  claim 1 , wherein the transmitting unit converts and transmits the JPEG 2000 code stream in at least one of a case where the graphical data cannot be generated as an HTML-based page, or a case where an application generates and controls the graphical data itself. 
     
     
         3 . The apparatus of  claim 1 , wherein the transmitting unit inserts the JPEG 2000 code stream into an isochronal packet, and transmits the isochronal packet as an isochronal stream. 
     
     
         4 . The apparatus of  claim 1 , wherein the apparatus is part of an expandable Home Theater (XHT) network. 
     
     
         5 . An apparatus for receiving graphical data, the apparatus comprising:
 a receiving unit that extracts an JPEG 2000 code stream from a received stream;   a decoder that decodes the JPEG 2000 code stream; and   a display unit that displays a video stream included in the received stream and the decoded JPEG 2000 code stream.   
     
     
         6 . The apparatus of  claim 5 , wherein the receiving unit comprises an isochronal stream extracting unit that removes a header of the received stream and extracting the JPEG 2000 code stream. 
     
     
         7 . The apparatus of  claim 5 , further comprising a synthesizing unit for synthesizing the decoded JPEG 2000 code stream and the video stream. 
     
     
         8 . A method of transmitting graphical data, the method comprising:
 generating graphical data;   converting the graphical data into a JPEG 2000 code stream; and   transmitting video streams and the JPEG 2000 code stream.   
     
     
         9 . The method of  claim 8 , wherein converting the graphical data is performed by converting the graphical data into the JPEG 2000 code stream in at least one of a case where the graphical data cannot be generated as an HTML-based page, or a case where an application generates and controls the graphical data. 
     
     
         10 . The method of  claim 8 , wherein transmitting the video streams and the JPEG 2000 code stream is performed by inserting the converted JPEG 2000 code stream into an isochronal packet, and transmitting to the isochronal packet as an isochronal stream. 
     
     
         11 . A method of receiving graphical data, the method comprising:
 extracting a JPEG 2000 code stream from a received stream;   decoding the JPEG 2000 code stream; and   displaying the decoded JPEG 2000 code stream and a video stream included in the received stream.   
     
     
         12 . The method of  claim 11 , wherein extracting the JPEG 2000 code stream is performed by removing a header of the received stream and extracting the JPEG 2000 code stream. 
     
     
         13 . The method of  claim 11 , further comprising synthesizing the decoded JPEG 2000 code stream and the video stream.
