Abstract: Techniques for high dynamic range image processing are presented. Base layer data, first checksum parameter, and residual ratio data for a high dynamic range (HDR) image are each received. A second checksum parameter is computed for the base layer data based upon the first SOF after the last APP11 marker segment and includes all following bytes up to and including the EOI marker. The first and second checksum parameters are compared to determine if base layer has been altered.

Abstract: JPEG-2000 data is formatted into RTP packets for transmission through the Internet. A priority field is provided in the format, and a value indicating the importance of a code stream included in a packet is stored therein. A type field indicates a payload type of a JPEG-2000 code stream. An mh_id field is provided as an identifier of a main header of the JPEG-2000 code stream and indicates a change in the main header. An mh_length field indicates the length of the main header and a fragment offset field stores the number of offset bytes from the start of an image of the packet.
