`
`Abstract of KR1G0253230 (BT)
`
`PURPOSE: A unix network sub-system for continuous meciurn stream transfer is
`provided to minimize a radiation movement of a data by clients by directly transmitting
`a continuous medium stream data received from a ile system through a buffer through
`a network when a siream control command is received from a server manacer.
`CONSTIPUTION: A plurality of operating modules(C OM} transmit a continuous medium
`stream data received fram a buffer through @ pre-set connection, anc is dynamically
`generated or terminated. A management module(CAM) dynamically manages the
`operating mocdule(COM) for every stream according fo a stream control command
`received from a server manager. The management module(CAM) incluces a manager
`agent for interpreting the received stream contral cormmand and performing a
`command, an operation module manager for generating, controlling and managing the
`operation module(COM}), a connection managerfor setting up and reigasing a
`connection, a QoS repeater for converting a QoS{Quality of Service) of a user received
`from the buffer fo a QoS of a network and maintaining a commection by means of the
`connection manager, an address repeater for converting a session ID received tram the
`buffer to an address of a client and outputting it, an admission checker for checking the
`amount of a network resource for a new session request by the buffer and checking
`whether the request can be admitted: and a system tuner far changing a tuning
`parameter value of a continuous medium network sub-system. The operation
`module(COM) includes a command receiver for receiving a management command
`from the management module(CAM) and processing it, a discarder for discarding a
`frame remaining in the buffer after releasing the connection, an error controller for re-
`transmitting a date lost during transmission for accurate transmission, a frame stamper
`for informing a transmission state of a frame being transmitted, a frarne divider for
`dividing the received frame suitably to each cent, and a flow controller for controlling a
`transfer rate.

`
`SYSTEM & METHOD FOR DISTRIBUTING MULTI-MEDIA
`
`PRESENTATIONS IN A COMPUTER NETWORK
`
`FIELD OF THE INVENTION
`
`The present invention relates to a method and system for distributing
`
`video, audio graphic and textual information on a computer network.
`
`BACKGROUND OF THE INVENTION
`
`Computer networks,
`
`in particular the INTERNET network, allow users
`
`19
`
`operating user operated displays (UOD) connected to the network, to receive and
`
`display multi-media presentations. Usually, multimedia presentations are stored as
`
`files which are downloaded from sites of the network in which they are stored and
`
`to which they were fed from any source.
`
`in the prior art, each multi-media file stored in a network site contains all
`
`15
`
`the data of a presentation, i.e. if the multi-media presentation is a video clip of a
`
`song, the file stored in the network site includes the video, audio, graphic and
`
`textual data of the particular video clip and therefore, when retrieved by a network
`
`user, a relatively tong delay exists before the user can display the presentation on
`
`his computer since the volume of data that needs to be transferred from the
`
`20
`
`network site fo the user is very large.
`
`For example, if the multi-media presentation is a G60 Kbyte file, it will be
`
`transferred via a 14.4K modem in about 12 minutes. An example of such 660 Kbyte
`
`file is a 1 minute audio file at 17 Ksamp/sec.

`
`SUMMARY OF THE INVENTION
`
`An object of the present invention is to provide an improved method and
`system for distributing multi-media presentations to users of a computer network,
`
`Another object of the present invention is to provide substantially in real
`time multi-media presentationsto at least one user operating a UOD connected to
`the network.
`
`A further object of the present invention is to enable a user operating a
`UOD to selectively display portions of or the entire multi-media presentation. The
`user operating the UOD may display the presentation with a desired delay, to re-
`display portions of the presentation or to dispiay portions of the presentation out of
`order.
`
`it will be appreciated that the terrn multi-media refers herein to video,
`audio, graphic, textual, music instrument deviceinterface (midi) or any otherdigital
`data, each taken alone or in any combination therebetween. The term display refers
`herein to the display of any data included in the multi media presentation.
`
`According to an aspect of the presentinvention, the system enabling the
`Selective display includes a feeding unit which feeds the multimedia presentation,
`& forming and distribution unit which feeds the multimedia presentation as data files
`including segrnents of the presentation and a UOD, all connected in any suitable
`computer network. Preferably, the data files include consecutive segments of the
`presentation.
`
`According to a preferred embodiment of the present invention,
`computer network is the INTERNET network.
`
`the
`
`According to a further aspect of the present invention, for the INTERNET
`network, the forming and distribution unit reside in World Wide Web (WWW)sites.
`The forming unit and the distribution unit may be either in the same WWW site or
`in a different WWWsite.

`
`According to yet another aspect of the present invention, the forming unit
`may be part of the feeding unit wherein the distribution unit is a HyperText Transter
`
`Protocal (HTTP) server in a WWW site.
`
`According to yet another aspect of the present invention, additional
`distribution units located in additional sites of the WWW mayretrieve the data files
`
`including the segments of the multi-media presentation from the distribution unit and
`
`distribuis them to additional users employing UODs communicating with these
`
`additional sites.
`
`One advantage of the present invention is that the communication
`protocol employed for connecting the UOD, the HTTP WWW server and the multi-
`media presentations feeding computer is a communication protocol presently used
`in the INTERNET, preferably a reliable TCP/IP communication protocol. TCP/IP is
`compatible with HTTP WWW and browsing applications used for browsing the
`
`WWW.
`
`According to a second preferred embodiment of the present invention,
`the communication protocolis any sultable communication protocol, such as a non-
`
`reliable UDP communication protocol.
`
`There is thus provided, according to a preferred embodiment of the
`invention, a method for distributing a multi-media presentation in a
`| present
`computer network which includes the following steps:
`A,
`feeding at least one site of the computer network with a stream of data
`
`of ihe presentation;
`B.
`forming, in each site a plurality of data files, each data file including a
`
`segment of the multi-media presentation;
`C.
`distributing the plurality of data files to at least one display; and
`
`D.
`
`displaying the distributed data files.
`
`in accordance with a preferred embodiment of the present invention, the
`feeding includes providing at least one parameter characterizing the segment anc
`the forming includes forming consecutive data files, each including the segmentin
`
`30
`
`accordance with the al least one parameter.

`interactive display application operating to receive the distributed datafiles and to
`display them in a user selected sequence. Preferably, the user selected sequence
`is selected from the group which includes displaying a most currentfile, displaying
`a formerly formedfile, displaying a formerly distributedfile, re-displaying displayed
`files and displaying the files out of order. The most currentfile refers herein to the
`file most recently formed by the forming unit.
`
`Further, according to a preferred embodiment of the present invention,
`the method may include the step of selecting a time lag between the steps of
`feeding and forming and the steps of distributing and displaying, the time lag
`determined whether the display is substantially a real time display or a delayed
`display.
`
`Still further, according to yet another preferred embodiment of the
`present invention, the step of distributing may also include the step of distributing
`the data files to additional distribution units operating to distribute the data files to
`additional displays.
