<P>PROBLEM TO BE SOLVED: To provide a small and lightweight communication apparatus making it possible to use various services. <P>SOLUTION: A signaling unit 103 of a display terminal 100 establishes communication with a content server, a video communication terminal, and a PC server through a communication unit 102, and transmits/receives image data compressed by MPEG2, MPEG4, and JPEG. A media control unit 105 switches compression schemes for decoding in a media processing unit 104 on the basis of the received image data. The media processing unit 104 performs decoding processing including inverse orthogonal transformation processing and dequantization processing in accordance with the switched compression scheme. At this time, a single processing circuit performs the inverse orthogonal transformation processing and the dequantization processing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
