Abstract:
A signal transmitting apparatus for transmitting high-speed video signals, said video signals being obtained by picking up an image of an object by an image pickup means at a speed which is predetermined times faster than that of a first video signal, comprising;a converting means for converting the output of said image pickup means into digital signals, a signal dividing means for forming digital video signals having the speed of said first video signal from the high-speed video signals outputted from paid converting means at every unit, dividing said digital video signals into a plurality of channels and outputting said digital video signals, a first signal processing means for performing a predetermined camera signal process to each of the output signals of said signal dividing means, converting said output of said signal dividing means into digital signals of said plurality of channels in the predetermined transmission format and outputting said digital signals, wherein said signal dividing means generating an indication signal when high-speed video digital signals having a multiple number smaller than the number of channels of said signal dividing means are inputted from said converting means, the indication signal indicating the period in which no digital video signal having the speed of said first video signal exists on divided channel, and outputting said indication signal to said first signal processing means, said first signal processing means outputting the digital signals of a predetermined transmission format, the period in which no digital video signal having the speed of said first video signal exists, and said indication signal, a transmission path for transmitting the output of said first signal processing means, a second signal processing means for converting said digital signals of said predetermined transmission format which have been transmitted through said transmission path into said digital video signals having a plurality of channels, an output means for converting the output of said second signal processing means into digital signals in the predetermined format and for outputting said digital signals, and a memory means for writing each of said digital video signals of said plurality of channels outputted from said second signal processing means, and reading said digital video signals of said plurality of channels outputted from said transmission path and arranged at every unit time with additional data period which is added in responsive to said indication signal and outputting said digital signals of said plurality of channels with each additional data period which have been read by said memory means to said output means, wherein said output means selects and outputs said digital video signals of said plurality of channels with additional data period which have been read by said memory means.
