ABSTRACT:
In a transmitting apparatus, information signal frame position information is supplied from a transmission line frame control unit in a frame constructing unit to an information signal frame control unit provided within a frame constructing unit. In a reception apparatus, information signal frame position information is supplied from transmission line frame control unit provided within a frame analyzing unit to an information signal frame synchronization detection protecting unit provided within a frame analyzing unit. n information signal frames having a length which results from dividing the data area of the transmission line frame by n are located at an arbitrary position within the data area of the transmission line frame and a stuff control is effected on every information signal frame. Also, a value of n which yields a stuff ratio in which a residual jitter can be prevented from being increased is selected by transmitting a single information signal by using n information signal frames.
