隨著電腦科技與網路資訊的進步，人們對於影像畫質的要求越來越高，HDTV（高畫質電視）、DVD（數位多功能光碟）、Videoconference（視訊會議）等數位影像技術便應運而生，這些技術皆須處理龐大的圖形及影像，而MPEG即是為了處理這些問題所製定的壓縮標準。 Along with the progress of computer technology, the demand of thequality of image is getting higher and higher. Some digital videotechnologies, like HDTV (High Definition Television), DVD ( DigitalVersatile Disc) and Videoconference are adopted to achieve thisrequirement to process large amount of pictures and video images. TheMPEG is the compression standards to solve the problem during theprocess. Both HDTV (High Definition Television) and DVD (DigitalVersatile Disc) need a MPEG-2 Decoder which include three major parts:the MPEG-2 System Decoder, the MPEG-2 Video Decoder and the MPEG-2Audio Decoder. And the MPEG-2 Bit Streams include three major parts:the data signals, the video signals and the audio signals. The videoSignals is sent to MPEG-2 Video Decoder and the audio signals is sentto MPEG-2 Audio Decoder. The different of the HDTV (High DefinitionTelevision) and the DVD (Digital Versatile Disc) is at the systemdecoder. The program streams are decoded by the system decoder of theDVD (Digital Versatile Disc). And the transport streams are decoded bythe system decoder of the HDTV (High Definition Television). The noiserejection of the transport streams is better than the noise rejectionof the program streams. In the thesis, the program stream and thetransport stream will be decoded by the system decoder. We can watchHDTV and DVD at the same box. We use the VHDL language to implementthe circuit of the MPEG-2 System which include of the program streamsand the transport streams. We use the tool of the MaxPlusII to writethe VHDL code to the demo board (10K20RC240-3) of the ALTERA company.
