Patent ID: 7551672

Claim:
An encoding system for encoding input video data, comprising: input means for providing input video data exhibiting a particular frame frequency converted from a second frame frequency; counting means for counting fields in the input video data of said particular frame frequency to produce a count; converting means for converting the input video data having said particular frame frequency into video data with said second frame frequency; encoding means for encoding the converted video data to generate an elementary stream and including, in said elementary stream, picture order information about a picture order of said elementary stream; said encoding means generating said picture order information based on the fields counted in said counting means; said picture order information including a presentation time stamp count corresponding to the count of said counting means and a decoding time stamp count representing decoding times for the pictures of said elementary stream; a packetizer for packetizing said elementary stream with said presentation and decoding time stamp counts; extracting means for extracting from said input video data information representing number of lines corresponding to a vertical start position of an active video area and number of samples corresponding to a horizontal start position of said active video area; and supply means for supplying the extracted information to a controller thereby supplying unique information pertaining to V-phase and H-phase positioning of said active video area.
