US 2006/0222073 A1 · Authoring running marks in compressed data

Abstract

Authoring at least one Running Mark in a compressed data stream is taught. The compressed data stream is preprocessed to decompress frames. The decompressed frames may be decoded and stored in a memory. In addition, one or more encoding parameters for each decoded frame may be stored in the memory. The decoded frames may be processed for Running Mark insertion. From among these frames, at least one candidate frame is determined and selected for Running Mark insertion. For each selected, at least one candidate macroblock is determined and selected. One or more Running Marks may be inserted into the selected candidate macroblocks for creating a Running Mark macroblock. At least one link connected to at least one of the Running Mark macroblocks may be modified. The modification may generate modified frames, which in turn, may be reconstructed for display.

Dependent claims

A method of authoring at least one Running Mark in a compressed data stream comprising:

a. preprocessing said compressed data stream, said preprocessing comprising:
i. generating decompressed frames by decompressing frames in said compressed data stream;
ii. generating decoded frames by decoding said decompressed frames;
iii. storing said decoded frames in a memory;
and
iv. storing at least one encoding parameter for each of said decoded frames in said memory;
b. processing said decoded frames for Running Mark insertion, said processing comprising:
i. determining at least one candidate frame from among said decoded frames;
ii. selecting at least one of said “at least one candidate frame”;
iii. determining at least one candidate macroblock for each of said candidate frame that is selected;
and
iv. selecting said at least one candidate macroblock to be a Running Mark macroblock for inserting at least one Running Mark;
c. generating modified frames by modifying at least one link connected to at least one of said Running Mark macroblock;
and
d. reconstructing said modified frames.
