Abstract:
A serial digital data transmitting apparatus comprising:digital packet generating means for generating a first digital packet conforming to the format for a second digital packet, said first digital packet comprising:a payload portion into which digital data is inserted;a first start synchronization code storage portion positioned at a preceding portion of said payload portion into which a start synchronization code is inserted, said start synchronization code indicating a start of said digital data inserted into said payload portion;a first end synchronization code storage portion into which an end synchronization code is inserted, said end synchronization code indicating an end of said digital data inserted into said payload portion; andan ancillary data storage portion positioned between said first end synchronization code storage portion and said first start synchronization code storage portion, and into which an ancillary data including line number is inserted;wherein said second digital packet comprises:an active video portion corresponding to said payload portion into which video data is inserted;a second start synchronization code storage portion corresponding to said first start synchronization code storage portion positioned at a preceding portion of said active video portion into which said start synchronization code is inserted, said start synchronization code indicating a start of said video data inserted into said active video portion;a second end synchronization code storage portion corresponding to said first end synchronization code storage portion into which said end synchronization code is inserted, said end synchronization code indicating an end of said video data inserted into said active video portion; andan auxiliary data storage portion corresponding to said ancillary data storage portion positioned between said second end synchronization code storage portion and said second start synchronization code storage portion, and into which auxiliary data is inserted;said line number being inserted in a line number storage portion of said ancillary data storage portion positioned in proximity to said first end synchronization code storage portion in said ancillary data storage portion, said line number being indicative of the line number of a video frame; andserial digital transmitting means for translating said first digital packet into said serial digital data and transmitting said serial digital data.
