	Video decompression operates on already RNC-unpacked videodata. Each frame is encoded using 4x4 blocks. Encoded stream starts with block type tags array. Each tag has 2 bits, first tag in bits 7-6 of byte, then 5-4 and so on. Remainder carries actual pixel values.		Video decompression operates on already RNC-unpacked videodata.
