Abstract
A method and system are provided for capturing and compressing an original uncompressed video signal which enables decoding and reversible reconstruction of a decompressed version of the original video signal. The system includes an input for receiving a signal indicating a special effect operation by which a first frame of a video signal is irreversibly transformed to a special effect frame. This is achieved by combining decompressed frame pixel data of the first frame with information comprising either pixel data of a second frame or a single scaling value to be used to scale plural pixels of a frame. The information indicates a special effect operation which can be performed on decompressed pixel data of the first frame to produce a special effect frame (e.g., the information can include a separate indicator specifying a specific operation or the information by its mere presence can indicate the special effect operation). The system also includes a processor for compressing pixel data of the first frame. The processor is also for constructing a bitstream containing the compressed pixel data of the first frame and the information. The bitstream is decompressible in a first manner to reproduce a decompressed video signal including the special effect frame, produced by performing the indicated special effect operation, in place of the first frame. The bitstream is also decompressible in a second manner to produce a decompressed version of the video signal with the first frame and without the special effect frame. The system and method according to this embodiment form a novel bitstream containing the compressed video frames and the information which can be stored on a storage medium. A system is also provided with a demultiplexer, decompressor and special effects generator for presenting the video signal with or without the special effect.
