IMAGE SIGNAL TRANSMITTER AND RECEIVER

摘要

PROBLEM TO BE SOLVED: To obtain an inexpensive image transmitter and receiver by converting a format of the second parallel digital image signal into the first parallel digital image signal and multiplexing the second parallel digital image signal format- converted during a digital blanking period of the first parallel digital image signal. SOLUTION: For a total of 30 bits of a HDTV digital YPbPr signal outputted from a digital HDTVYPbPr signal source 100, a HDGTV digital Pb signal 10 bits and a Pr signal 10 bits applies a two-time division multiplexing and is converted in to a signal of HDTV digital YPbPr signal total of 20 bits in a PbPr time division multiplexing means 101. An input of a format conversion means 103 is an NTSC digital signal of 14.3 MHz 10-bit parallel nonperiodically and outputs an HDTV digital signal of parallel of 20-bit unit of 74.25/1.001 MHz.
