Abstract
A digital data delivery system that delivers video data of a content and audio data of the same content respectively to a first receiver and a second receiver, which are independent of each other, to reproduce the video data and the audio data at the first and second receivers in such a manner as to secure synchronous reproductions between the two data. The digital data delivery system includes a transmission server which delivers a video data packet and a video synchronization signal packet to the first receiver and an audio data packet and an audio synchronization signal packet which indicates a time on the same reference time axis as that of the video synchronization signal packet to the second receiver, the first receiver which adjusts a clock signal based on the video synchronization signal packet and reproduces the video data packet based on this clock signal, and the second receiver which adjusts a clock signal based on the audio synchronization signal packet and reproduces the audio data packet based on this clock signal.
