Patent ID: 7583708

Claim:
A data transmitting apparatus comprising: a plurality of serial/parallel converting means to which first serial digital video signals of n channels, where n is an integer of 2 or more, forming bit string data, each of which has a bit rate defined by a standard, are supplied, to obtain first word string data of n channels forming a parallel digital video signal, each of which has a line portion data structure defined by a standard; a plurality of 8 bit/10 bit converting means to which the first word string data of n channels, which is obtained from the plurality of serial/parallel converting means, is supplied, to apply 8 bit/10 bit converting processing to each of the first word string data of n channels by a first predetermined bit number at a time, and to form second word string data of n channels, each of which has a predetermined word bit number; data multiplexing means which multiplexes the second word string data of n channels which is obtained from the plurality of 8 bit/10 bit converting means, to form multiplex word string data; data length converting means for converting the formed multiplex word string data to a sequential data string having additional data utilized for speed adjustment; multiple channel data forming means which takes out the converted multiplex word string data which is obtained from the data multiplexing means, by a second predetermined bit number at a time, to form bit string data of m channels (m is an integer which is larger than n), each of which has a predetermine bit rate; data multiplexing and parallel/serial converting means which multiplexes bit string data of m channels, which is obtained from the multiple channel data forming means and also applies parallel/serial conversion thereto, to form bit string data in which a data rate is 10 Gb/s or more, as a second serial/digital video signal; and data sending away means which sends away to transmit bit string data which is obtained from the data multiplexing and parallel/serial converting means and in which a data rate is 10 Gb/s or more.
