摘要： A system for encoding data blocks and methods of operating the same result in a video encoder that provides advanced intelligent encoding. The video encoder comprises DCT (discrete cosine transformer) resources configured to DCT the data blocks. Quantizing resources is coupled to the DCT resources configured to quantize the data blocks to provide quantized data blocks. Inverse quantizing resources is coupled to the quantizing resources to inverse quantize the quantized data blocks. Frame reconstruction resources is coupled to the inverse quantizing resources configured to reconstruct previous compressed frames. Motion estimation resources is coupled to the frame reconstruction resources configured to provide predicted data blocks. Subtraction resources is coupled to the DCT resources and the motion estimation resources to subtract the data blocks and the predicted data blocks. An output data buffer is coupled to the quantizing resources configured to provide a data rate signal to the quantizing resources for modifying quantizer values of the quantizing resources in order to maintain a particular target output data rate of the compressed image data.

Quantizing resources is coupled to the DCT resources to quantize the reduced data blocks to provide quantized data blocks. Inverse quantizing resources is coupled to the quantizing resources to inverse quantize the quantized data blocks. Frame reconstruction resources is coupled to the inverse quantizing resources to reconstruct previous compressed frames. Motion estimation resources is coupled to the frame reconstruction resources to provide predicted data blocks. Subtraction resources is coupled to the DCT resources and the motion estimation resources to subtract the data blocks and the predicted data blocks. An output data buffer is coupled to the quantizing resources and the inverse quantizing resources configured to provide previous compressed image data in response to an update request while maintaining a particular target data rate to the decoder.

摘要： Methods for pre-processing video sequences prior to compression to provide data reduction of the video sequence. Also, after compression of the pre-processed video sequence, the bit rate of the pre-processed and compressed video sequence will be lower than the bit rate of the video sequence after compression but without pre-processing. Pre-processing may include spatial anisotropic diffusion filtering such as Perona-Malik filtering, Fallah-Ford filtering, or omni-directional filtering that extends Perona-Malik filtering to perform filtering in at least one diagonal direction. Pre-processing may also include performing filtering differently on a foreground region than on a background region of a video frame. This method includes identifying pixel locations having pixel values matching characteristics of human skin and determining a bounding shape for each contiguous grouping of matching pixel locations. The foreground region is comprised of pixel locations contained in a bounding shape and the background region is comprised of all other pixel locations.

摘要： A method, apparatus, system, and signal-bearing medium that in an embodiment detect that a first packet is not received, add a place holder for the first packet in a buffer, request retransmission of the first packet, and create an estimated packet based on a combination of a second packet previous to the first packet, a third packet following the first packet, and a fourth packet from a previous frame that is spatially corresponding to the first packet. In another embodiment, a method, apparatus, system, and signal-bearing medium are provided that send a encoded packet to a receiver, save the encoded packet in a bitstream, determine whether the encoded packet is lost, and when the encoded packet is lost, decode the bitstream with the lost packet omitted and insert a reconstructed frame associated with the lost packet into a reference frame storage. In another embodiment, when the encoded packet is lost, a decoder is run on a reference frame chosen as the last uncorrupted frame. In another embodiment, when the encoded packet is lost, the decoder is run on a frame chosen from a set of previously stored reference frames.

摘要： Improved method and apparatus for vector quantization (VQ) to build a codebook for the compression of data. The codebook or "tree" is initialized by establishing N initial nodes and creating the remainder of the codebook as a binary codebook. Children entries are split upon determination of various attributes, such as maximum distortion, population, etc. Vectors obtained from the data are associated with the children nodes, and then representative children entries are recalculated. This splitting/reassociation continues iteratively until a difference in error associated with the previous children and current children becomes less than a threshold. This splitting and reassociating process continues until the maximum number of terminal nodes is created in the tree, a total error or distortion threshold has been reached or some other criterion. The data may then be transmitted as a compressed bitstream comprising a codebook and indices referencing the codebook.

In addition, after compression of the pre-processed video sequence, the bit rate of the pre-processed and compressed video sequence will be lower than the bit rate of the video sequence after compression but without pre-processing. A temporal filtering method is provided for pre-processing of video frames of a video sequence. In the method, pixel values of successive frames are filtered when the difference in the pixel values between the successive frames are within high and low threshold values. The high and low threshold values are determined adaptively depending on the illumination level of a video frame to provide variability of filtering strength depending on the illumination levels of a video frame.
