Trick mode using a dummy predictive picture of interlaced

摘要

This invention in method regards 200 in order to execute trick mode in the video signal which includes the plural field pictures and system 100. This method the step using one estimate scheme at least in 212 which receives the command of trick mode, and field based estimate and frame based estimate, includes the step 216 which at least inserts the estimate picture of one dummy selectively in the video signal of the said trick mode. With one constitution, as for the step which description above and selectively is inserted, using field based estimate, using step, and the frame based estimate which at least insert the first dummy estimate picture selectively in the said video signal, it includes the step which after that inserts the dummy estimate picture selectively in the video signal of the said trick mode.
