Abstract
Decompressing compressed video information using relatively less temporary storage is disclosed. A compressed bit stream of video information including a compressed portion is received. A reverse combination in the transform domain is performed on the compressed portion to produce two corresponding portions of video information, where the two portions represent the compressed portion in a less compressed form. The two portions of video information are temporarily stored as a reverse combination is being performed. One of said two portions of video information is transformed, decoded, and decompressed to produce a decompressed portion of video information. The decompressed portion of video information is output.
