US Patent 7583708 Data transmitting apparatus and data receiving apparatus

A data transmitting apparatus and a data receiving apparatus, which multiplexes and transmits HD-SDI signals, and receives the multiplexed and transmitted HD-SDI signals, respectively. The data transmitting apparatus includes a parallel data forming section that forms word string data based on HD-SDI signals having n channels. A data multiplexing section obtains multiplex word string data based on the formed word string data. A multiple channel data forming section forms bit string data of m channels from the multiplex word string data. A data multiplexing and P/S converting section forms bit string data based on the formed bit string data, whereby a bit rate is set to 10 Gb/s or more. An electric photo converting section transmits the formed bit string data.
