Patent ID: 8160134

Claim:
An encoding apparatus for encoding input video data having an active video area whose vertical and horizontal position is relative to a full pixel area, said input video data having blanking intervals, comprising: extraction means for extracting ancillary data from the blanking intervals of said input video data and for extracting location data representative of the vertical and horizontal position of the active video area with respect to the full pixel area of the input video data; counting means for counting fields in said input video data; encoding means for encoding the active video area of said input video data to generate encoded streams including a picture layer and a sequence layer; and control means for controlling said encoding means so as to insert said ancillary data and said vertical and horizontal position data into the encoded streams, wherein said control means describes said ancillary data in a user data area in the picture layer of said encoded streams, and said vertical and horizontal position data in a user data area of the sequence layer of said encoded streams, and said control means controls said encoding means to insert into said picture layer 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 encoded stream.
