Two-Pass Encoding Method Of Digital Motion Video Sequences For Constant-Or Variable Bit Rate

View page
US Patent:
6614935, Sep 2, 2003
Filed:
Sep 20, 2000
Appl. No.:
09/666667
Inventors:
Rajesh Rajagopalan - Bedminster NJ
Peter Westerink - Ossining NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06K 936
US Classification:
382232, 382234, 3752401
Abstract:
Systems and methods are provided for for encoding units of digital information such as pictures, whereby all the data is first analyzed by running a compression pass over all the data, using the in the encoder embedded rate control mechanism. Picture attributes, such as quantization scale setting and bits produced will be extracted from the resulting bitstream, and analyzing this, indiviudal unit (picture) quantization scale and bit allocation settings are prepared for a next pass for either a constant- or variable bit rate, whereby buffer boundaries are observed. In a second compression pass through the same data, a constant- or variable bit rate compressed bitstream is produced, but this time bypassing the embedded rate control mechanism, and using the prepared picture bit allocation and quantization scale settings instead. Additionally, a mechanism will supervise the total bit production accuracy.

US Patent:
7286571, Oct 23, 2007
Filed:
Jul 19, 2002
Appl. No.:
10/199236
Inventors:
John Norman Mailhot - Bridgewater NJ, US
R. Scott McCaskill - Newton NJ, US
Rajesh Rajagopalan - Fremont CA, US
Robert A. Resuta - Bridgewater NJ, US
Michael J. Scheutzow - Parsippany NJ, US
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H04J 3/02
US Classification:
370537, 370487
Abstract:
The present invention provides systems and methods for providing on-demand datacasting. A system according to an exemplary embodiment of the present invention comprises a rate generator for controlling the rate at which data signals are combined with audio/video signals. The system may also include a system controller for controlling the rate of the rate generator. The system controller may also monitor the complexity of the audio/video signals, calculate an average complexity of the audio/video signals, calculate an average complexity of the audio/video signals and determine whether the average complexity is greater than the typical complexity of audio/video signals. The system controller may adjust the rate of the rate generator based on the determination of whether the average complexity of the audio/video signals is greater than the typical complexity of audio/video signals.

Single Pass Target Allocation For Video Encoding

US Patent:
61817422, Jan 30, 2001
Filed:
Jan 26, 1998
Appl. No.:
9/013148
Inventors:
Rajesh Rajagopalan - Bedminster NJ
Thomas McCarthy - Cortlandt Manor NY
Cesar Gonzales - Katonah NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04N 712
US Classification:
375240
Abstract:
Systems and methods are provided for allocating bits to pictures in accordance with the bit allocation constraints for operation at both constant and variable bit rates. A statistical complexity measure which is an estimate of the average encoding complexity of the entire data is updated after encoding each picture. This set of parameters, along with an estimate of the encoding complexity of the current picture and the desired average coding rate is used to allocate target bits for encoding the current picture. One method of allocating bits to a picture is to used the statistical complexity measure to vary the instantaneous rate of encoding and allocate bits for this picture so as to generate encoded data at this rate. Another method is to modulate the target generated by a conventional encoder using the current level of the Virtual Buffer Verifier and the deviation of the estimated encoding complexity of the current picture from the statistical complexity measures.
