Patent number: 6882686Abstract: The object-oriented coder discriminates resource allocation between objects and non-objects for video messaging applications over wireless networks. The object-oriented coder executes a rate control algorithm, an unequal error protection algorithm, and an error concealment algorithm. In the rate control algorithm, an iterative feedback rate control scheme is used in which quantization values of object and non-object data are held constant. In the unequal error protection algorithm, the bit stream is partitioned by object macroblocks and non-object macroblocks. In the error concealment algorithm, five bits of QUANT values of each GOB are used for representing location and motion vectors of the object in the next frame, since the quantization value is constant. The five bits are not used for quantization value. The five bits are used for error concealment to avoid bit rate overhead. The object-oriented coder increases encoding delay, but this increase is acceptable in messaging.Type: GrantFiled: June 6, 2001Date of Patent: April 19, 2005Assignee: Georgia Tech Research CorporationInventors: Nikil Jayant, Seong-Hwan Jang

Patent number: 6028896Abstract: A method for controlling the data bit rate of a differential pulse code modulation/discrete cosine transform (DPCM/DCT) video encoder, which is adapted to achieve a bit rate control in accordance with a video signal band compression scheme using a differential pulse code modulation (DPCM) and a discrete cosine transform (DCT), thereby obtaining a supreme picture quality while preventing a buffer overflow or underflow phenomenon from occurring in the encoder. The method includes the steps of determining an initial bit allocation amount for every group of pictures (GOP) of an input video, allocating bits for every picture of each GOP, allocating bits for every macroblock of each picture, determining a quantizer step parameter based on the bit allocation amount, and determining a quantizer step size proportional to the determined quantizer step parameter.Type: GrantFiled: October 10, 1997Date of Patent: February 22, 2000Assignee: Korea Telecommunication AuthorityInventors: Seong Hwan Jang, Soon Hwa Jang
