Abstract:
1. A data receiving apparatus comprising: data receiving means which receives bit string data in which a bit rate is 10 Gb/s or more, as a first serial digital video signal; serial/parallel converting and multiple channel data forming means which applies serial/parallel conversion to bit string data which is obtained from the data receiving means and in which a bit rate is 10 Gb/s or more, to form bit string data of m channels (m is an integer of 3 or more), each of which had a predetermined bit rate; data multiplexing means which multiplexes bit string data of m channels which is obtained from the serial/parallel converting and multiple channel data forming means, to form multiplex word string data; data separating means which takes out the multiplex word string data which is obtained from the data multiplexing means, by a first predetermined bit number at a time, to obtain first word string data of n channel (n is an integer of 2 or more, which is smaller than m), each of which has a predetermined word bit number; a plurality of 10 bit/8 bit converting means to which first word string data of n channel, which is obtained from the data separating means, is supplied, to apply 10 bit/8 bit converting processing to each of the first word string data of n channels by a second predetermined bit number at a time, and to form second word string data of n channels, each of which is made as a parallel digital video signal having a line portion data structure defined by a standard; and a plurality of parallel/serial converting means to which second word string data of n channels, which is obtained from the plurality of 10 bit/8 bit converting means, is supplied, to obtain second serial digital video signals of n channels forming bit string data, each of which has a bit rate defined by a standard.
