VIDEO ENCODING SYSTEM

A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands are organized into blocks that are provided to a block-based encoder. The encoded frequency data is packetized and transmitted to a receiving device. On the receiving device, the enc...

description A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands are organized into blocks that are provided to a block-based encoder. The encoded frequency data is packetized and transmitted to a receiving device. On the receiving device, the encoded data is decoded to recover the frequency bands. Wavelet synthesis is then performed on the frequency bands to reconstruct the pixel data for display. The system may encode parts of frames (tiles or slices) using one or more encoders and transmit the encoded parts as they are ready. A pre-filter component may perform a lens warp on the pixel data prior to the wavelet transform.
