`Description
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates to an apparatus for
`transmitting and receiving image data, voice data, and
`other supplementary data over a network, and more
`particularly to a communications system capable of
`maintaining the real time requirement of such data.
`
`2. Description of the Related Art
`
`In recent years, with increasing performance of
`microcomputers and the advent of OSs equipped with
`networking capabilities, coupled with increasing speeds
`of peripheral interfaces and increasing performance of
`computers, dramatic changes have been occurring in
`the field of computers, particularly personal computers
`and workstations, these changesentailing changesin
`information that computers handle. Earlier, information
`handled by computers was character code, such as
`ASCII and JIS, but gradually expandedto include graph-
`ics and the like in the field of CAD, and nowadays, han-
`dling of multimedia information such as moving images
`and voiceis increasing in importance. The most notable
`feature of multimedia information is that information
`
`occurs continuously in real time (hereinafter referred to
`as the real time requirement). On the other hand, with
`the spread of high-speed wide area networks, networks
`are being commercially implemented that store and
`manage such multimedia data and that have fast data
`transfer rates that enable such data to be launched into
`the networks. What characterizes such networksis that
`
`whentransmitting signals having the real time require-
`ment over the network, the transmitting end must send
`out data notlater than the time expectedat the receiving
`end.
`
`One example of a network suitable for multimedia
`communications is the ATM (Asynchronous Transfer
`Mode) network. With ATM, transmission systems capa-
`ble of 156 Mbit/s, for example, have been commercially
`implemented. ATM specifications are being discussed
`and standardized by the ITU-T (International Telecom-
`munications Union-Telecommunication Standardization
`Sector), the ATM Forum, etc., and manyrelated books
`have been published. Besides ATM,
`there are other
`techniques, such as 100-Mbps Ethernet (100BASE-T)
`and Fiber Distributed Data interface (FDDI), that can
`provide fast transmission capabilities of 100 Mbit/s or
`higher and can achieve multimedia information commu-
`nications. With slower versions of Ethernet (IEEE 802.2,
`IEEE 802.3) also, since switching hubs are now readily
`available, each terminal connected to the switching hub
`is capable of a transmission rate of about 10 Mbit/s and
`is therefore able to transmit real time signals that do not
`require data rates higher than that. In the Internet also,
`
`signals having real time requirements, such as video-
`conferencing and Internet telephone signals, are being
`transmitted.
`
`Prior art examples of communications systemsfor
`real time signals are disclosed, for example,
`in Japa-
`nese Patent Unexamined Publication Nos. 7-170502, 7-
`170503, 7-170290, 7-170291, 7-170504, and 7-170292.
`Japanese Patent Unexamined Publication No. 7-
`170502 discloses a system in which, when the amount
`of video or voice data in a buffer memoryat the receiv-
`ing end exceeds an upperlimit value or drops below a
`lowerlimit value, the buffer memoryis controlled in such
`a manner as to discard portions of the video or voice
`data other thancritical portions thereof.
`Japanese Patent Unexamined Publication No. 7-
`170503 concerns a system in which, when the amount
`of videoor voice
