Abstract:
1. A method for repositioning images in a video data stream, said method comprising: storing encoded video data in a first buffer, said data including the representation of a first image at a first position in a displayed image; determining whether repositioning of the first image to a second position in the displayed image would result in a change of bit positions of the encoded first image data, said bit positions being determined with respect to a first number of bits; reading said video data from said first buffer; modifying said video data to reposition said first image; modifying said video data by generating one or more stuffing bits configured to restore said encoded first image data to said bit positions, in response to determining said repositioning would result in said change of bits positions; coding said stuffing bits such that upon decode said stuffing bits will not materially affect said displayed image; and storing said modified video data in a second buffer.
