International Classification:

H04N 712

US Classification:

37524013, 37524016, 348699

Abstract:

In accordance with one embodiment of the present invention, a method for encoding data is presented comprising receiving a stream of data to be encoded comprising a plurality of frames, selecting a frame-type for each of the plurality of frame, and grouping subsets of the plurality of frames based, at least in part, on the selected frame type to facilitate optimal, random access to select groups of frames, and to facilitate motion estimation.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04B 166

US Classification:

37524018

Abstract:

A method for encoding a frame of data is disclosed comprising receiving one or more data frames, low-pass filtering each of the received frames, horizontally subsampling each of the filtered frames by a scaling factor, and modifying the subsampled frames to resemble full frames.

Appl. No.:

09/120646

Inventors:

George K. Chen - Portland OR
Atul Gupta - Portland OR
Michael Keith - Salem OR
Jeffrey S. McVeigh - Portland OR
Stephen V. Wood - Hillsboro OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04N 593

US Classification:

386 52, 386 55

Abstract:

Digital video (DV) formatted image streams may be converted into an intermediate format having a lower resolution than the original image streams. A user may then edit the intermediate formatted image streams to generate a sequence of edit commands. The edit commands may then be processed to generate an output image stream based on the original image streams. The output image stream may be in any desired format, including DV format. The sequence of edit commands may also be processed to generate a preview image stream in the intermediate format.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04B 166

US Classification:

3752402

Abstract:

A method and apparatus for transcoding a digital video signal is described. A first set of bits encoded in a first encoding format are received. The first set of bits are decoded to discrete cosine transform (DCT) coefficients. The DCT coefficients are transformed into an intermediate exchange format. The transformed DCT coefficients are encoded using a second encoding format.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06K 936

US Classification:

382251, 382233, 382239, 382238

Abstract:

A method and apparatus for encoding a digital image is disclosed. A difference is calculated between a first sample from a current scan line and a corresponding second sample from a previous scan line. A quantization table level is selected from a quantization table that includes at least one level, and information identifying the selected level is placed into an information stream. A quantizer is selected from the quantization table level based on the calculated difference and information corresponding to the selected quantizer is place into the information stream.

Appl. No.:

09/209828

Inventors:

Michael Keith - Salem OR, US

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06K009/36

US Classification:

382238, 382236, 382239

Abstract:

In a video coding method, it is determined to code input video data according a technique selected from the group of: (a) intra-coding, (b) inter-coding without a residual and (c) inter-coding with a residual, wherein inter-coding codes the input video data with reference to coded video data at another time. When it is determined to code the input video data according to type (c) decoded video data of another frame is decoded and the the input data is coded according to the selected technique.

International Classification:

G06K009/36

US Classification:

382239

Abstract:

A method and apparatus for video conferencing is disclosed. According to one embodiment, a Universal Serial Bus (USB) enabled digital video camera may output an encoded information stream. The USB-enabled digital video camera including an encoder may compress image data received by the USB-enabled digital video camera during a real-time video conference to produce the encoded information stream in which no frame of the encoded information stream may depend on a previous frame by performing intra frame encoding. A computer system coupled to the USB-enabled digital video camera via a USB may be used to decode the encoded information stream and to transmit the image data to one or more other computer systems as part of a video conferencing data stream.
