Filed:

Aug 28, 2001

Appl. No.:

09/942260

Inventors:

Pierre Costa - Austin TX, US
Ahmad Ansari - Austin TX, US
John Robert Erickson - Austin TX, US

Assignee:

SBC Technology Resources, Inc. - Austin TX

International Classification:

H04B001/66

US Classification:

37524024, 37524023, 37524026, 37524025, 37524001, 375246, 382235, 382246, 382233

Abstract:

A method comprises determining a plurality of time intervals Tp and Tn within a variable bit rate (VBR) representation of an image sequence. The time intervals Tp are those in which a number of blocks of information per unit time is greater than a baseline value. The time intervals Tn are those in which a number of blocks of information per unit time is less than the baseline value. A second representation of the image sequence is created in which some blocks of information Bp are removed from the time intervals Tp and interlaced with blocks of information Bn in the time intervals Tn to reduce a variation in a number of blocks of information per unit time between the time intervals Tp and Tn.

Ahmad Ansari - Austin TX, US

Assignee:

SBC Technology Resources, Inc. - Austin TX

International Classification:

H04L 12/56
H04L 12/28
H04J 3/16

US Classification:

37039561, 370467

Abstract:

Society of Motion Picture and Television Engineers (SMPTE) video data is separated into first data and second data. A first signal is formed based on the first data. A second signal is formed based on the second data. The first signal is transported via a first Optical Carrier 3 (OC-3) channel. The second signal is transported via a second OC-3 channel.

International Classification:

H04N 7/12
H04N 11/02

US Classification:

3752402

Abstract:

A single compression engine determines a plurality of discrete cosine transform (DCT) coefficients based on a discrete cosine transform of a plurality of blocks of data. The single compression engine provides first and second DCT-encoded signals. The first DCT-encoded signal uses at most t coefficient bits to represent each of the DCT coefficients. The second DCT-encoded signal uses at most u coefficient bits, where u is less than t, to represent each of the DCT coefficients.
