DATA COMMUNICATION METHOD AND ELECTRONIC DEVICE, AND PROGRAM SUPPLYING MEDIUM FOR SUPPLYING DATA COMMUNICATION PROGRAM

摘要

In a communication system, asynchronous file data which does not require real time performance represented by still image data, text data, and a program file, and asynchronous file data having a low bit rate such as audio data and video data, all of which is outputted from a data source block (11) in a source device (10) is written into a memory (13), and the data is transmitted to a 1394 interface (14) by a processor (12). The 1394 interface (14) puts the asynchronous file data into an asynchronous packet and transmits the packet to a destination device (20) via a 1394 bus (30).
