Abstract: A method and system for compressing and decompressing video image data in real time employs thresholding and facsimile-based encoding to eliminate the need for computationally intensive two-dimensional transform-based compression techniques. The method operates first by forming a difference frame which contains only information pertaining to the difference between a current video image frame and a computed approximation of the video image frame. The difference frame is fed to a thresholder which categorizes each pixel in the frame as being either in a first set having intensities above or at a preset threshold, or a second set having intensities below a preset threshold. A facsimile-based compression algorithm is then employed to encode the first set of above or at threshold pixel locations. To compress the intensity data for each above or at threshold pixel, a quantizer and lossless encoder are preferably employed, with the quantizer serving to categorize the intensities by groups, and the lossless encoder using conventional coding, such as Huffman coding, to compress the intensity data further. Various techniques may be employed with the embodiments of the invention to adjust the actual amount of compressed data generated by the method and system to accommodate communication lines with different data rate capabilities.

Abstract: An embodiment improves the operation of a H.264 and Joint Scalable Video Codec (e.g., JSVC/H.264 Amendment 3) video decoder by managing neighboring block data during the decoding process. An embodiment pre-computes neighboring block tables to efficiently locate the neighboring block data required to decode a current macroblock. In particular, the pre-computed most probable joint neighboring block tables disclosed herein handle both macroblock adaptive frame field (MBAFF) coding and non-MBAFF coding. An embodiment is further capable of managing variable block sizes. Other embodiments are described and claimed.

Abstract: A method can include selecting a block of pixels. It may be determined whether the block of pixels contains an edge pixel. If the block of pixels contains an edge pixel, a first pixel may be selected among the block of pixels. If it is determined that the first pixel is a ringing noise pixel, a ringing filter may be applied. An edge-preserved filter may be applied if the first pixel is not a ringing noise pixel.
