Abstract: Systems and methods for transmitting source video (305) over a bandwidth-limited network (350). First, high frequency spectral content of the video is encoded into layer-1 data files (330). In parallel, frames of the video are downsampled (342) and compressed (333) using a lossy CODEC, to define layer-2 data files (335a, 335b) with high-frequency spectral content removed therefrom. The layer-1 and layer-2 data files are interleaved (345a, 345b) and transmitted over the network and are smaller than conventional lossy CODEC compressed files. After receipt, the layer-1 and layer-2 data files are deinterleaved. The layer-2 data is decompressed (353) and upsampled (362) to create a preliminary reconstructed video.

Abstract: Methods, systems, devices, and implementing technologies for up-scaling an original source video from a lower, first resolution to a desired output video having a higher, second resolution, using fractal zooming techniques to replace individual source pixels in each respective image frame of the original source video with a plurality of proposed replacement pixels in the vertical and horizontal dimensions having similar characteristics as the individual source pixel, reducing noise associated with each respective frame of the desired output video, re-sizing, as necessary, each respective replacement frame to the second resolution, and outputting each zoomed replacement frame to generate the desired output video, which is an up-scaled version of the original source video. The quality of the up-scaled output video is improved by using artifact filtering and linear smoothing techniques after the initial search and replace steps of the fractal zooming process.

Abstract: A codec, systems, and methods for compressing video data includes selecting a current video frame of the video data, dividing the current video frame into multiple blocks, wherein each block has M×N pixels, approximating the blocks of the current frame based on motion vectors associated with corresponding blocks from the previous frame, further refining the blocks of the current frame by determining optimal motion vectors for the blocks of the current frame based on the motion vectors provided (i) by the corresponding blocks from the previous frame, (ii) by the surrounding blocks in the current frame, and (iii) from successively smaller blocks within the current frame, wherein the optimal motion vectors for the blocks of the current frame are optimized to balance distortion and rate and wherein the optimal motion vectors are represented by codewords generated from Huffman tables.
