Abstract
A data communications system and a data communications method enable disappearance of digital AV data arranged into data packet to be prevented. An initialized state detector monitors the state of a transmission line whether or not an initialization protocol of a transmission line occurs. A packet controller arranges the digital AV data into data packet. When the transmission line is under the bus reset condition, it causes output of the digital AV data arranged into data packet to be interrupted due to control of a timing controller. While when the transmission line is not under the bus reset condition, it causes the digital AV data arranged into the data packet to be sent to the transmission line. A reception equipment connected to the transmission line receives the digital AV data arranged into the data packet sent from the transmission equipment before linking. Consequently, even though communication among the equipments is interrupted temporarily caused by the bus reset and so forth, it is capable of transmitting the whole data packets without omission, thus it becomes possible to transmit the picture and/or the sound without interruption.
