Abstract:
A device for converting a data transfer rate to provide communication of at least one of digital audio and video data between a first digital device and a second digital device, comprising:a transmitter providing a stream of source packets from the first digital device to the second digital device according to a transmission specification in an isochronous mode; andan alignment device determining insert positions of empty packets to convert transmission timing of an inner bus in the first digital device into a fixed timing according to the transmission specification wherein said alignment device comprises;a timing simulator receiving data signals and a mode signal and generating transmission basis signals; anda transmission timing controller receiving the transmission basis signals from said timing simulator and transmitting packets at every one of a plurality of cycle syncs of the transmission specification which occurs after a fixed length of time, wherein transmission of said packets is performed according to fixed rules;wherein the data signals occur after delaying a first signal, corresponding to the beginning of the transmission of first data in a frame of the inner bus in the first digital device, for a delay interval.
