Abstract

A network system includes a transmitting apparatus; a transmission path; a relaying apparatus that receives real time information transmitted through the transmission path; a wireless network; and a receiving apparatus that receives data transmitted through the wireless network. The relaying apparatus has a reference time generating part that generates a reference time independently of the transmitting apparatus; and a network transmitting part that transmits both the real time information received from the transmitting apparatus and the reference time via the wireless network. The receiving apparatus has a network receiving part that receives the real time information and reference time transmitted through the wireless network; an internal time management part that generates an internal time from the reference time received by the wireless network receiving part; and a real time information processing part that decodes the real time information received by the wireless network receiving part to reproduce the content data and that then outputs the content data, based on the internal time generated by the internal time management part. This network system allows the receiving apparatus to synchronize and output video and audio, regardless of singularity or plurality of the receiving apparatus.
