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 standard, said first digital packet standard comprising: a payload portion into which digital data is inserted; a first start synchronization code storage portion positioned at a preceding position 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; and an 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 an error detection code for detecting an error in header data 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; and an 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 error detection code is inserted in said first digital packet at an error detection code storage portion positioned in said ancillary data storage portion, and is constructed of a line number, source address, destination address, and block type; and serial digital data transmitting means for converting said first digital packet into serial digital data, and for transmitting said serial digital data.
