Patent number: 5870435Abstract: Disclosed is a quantization/inverse quantization circuit including a differential pulse code modulator (DPCM). Video CODEC standards (i.e., JPEG, H.261, H.263, MPEG-1, and MPEG-2) include various functions for an image compression and an image reconstruction. The conventional quantization/inverse quantization circuit has been designed to be fit for only one desired standard, so that the quantization/inverse quantization circuit used for one standard cannot be directly used for another standard. Accordingly, in relation to a difference between standards and required function therebetween in order to use the present invention in all video CODEC standards, the present invention discloses a quantization/inverse quantization circuit which can support all modes (i.e., a quantization mode in coding, an inverse quantization mode in decoding, and a reconstruction mode) by employing one quantization circuit as a quantization/inverse quantization circuit which can be used in all video CODEC standards.Type: GrantFiled: April 25, 1997Date of Patent: February 9, 1999Assignee: Electronics and Telecommunications Research InstituteInventors: Jang-Sik Choi, Byoung-Ki Min, Sang-Beom Kim, Seung-Ku Hwang
