Abstract

A new URL scheme, "vemmi" is defined. It allows VEMMI client software and VEMMI terminals to connect to multimedia interactive services compliant to the VEMMI standard (Enhanced Man-Machine Interface for Videotex and Multimedia/Hypermedia Information Retrieval Services), sometimes abbreviated as "VErsatile MultiMedia Interface".

VEMMI URL Specification

Status of this Memo

This document specifies an Internet standards track protocol for the

Internet community, and requests discussion and suggestions for

improvements. Please refer to the current edition of the "Internet

Official Protocol Standards" (STD 1) for the standardization state

and status of this protocol. Distribution of this memo is unlimited.

1) Abstract

A new URL scheme, "vemmi" is defined. It allows VEMMI client software

and VEMMI terminals to connect to multimedia interactive services

compliant to the VEMMI standard (Enhanced Man-Machine Interface for

Videotex and Multimedia/Hypermedia Information Retrieval Services),

sometimes abbreviated as "VErsatile MultiMedia Interface".

VEMMI is a new international standard for on-line multimedia

services, that is both an ITU-T (International Telecommunications

Union, ex. CCITT) International Standard (T.107) [2] and an

European Standard (ETSI European Telecommunications Standard

Institute) standard (ETS 300 382 [3], obsoleted by ETS 300 709 [1]).

VEMMI could be described as an on-line multimedia protocol describing

both the man-machine interface and the client/server exchange

protocol. VEMMI operates usually on a single continuous session

between a client and a host and supports an object-oriented, event-

driven, client/server oriented and platform independent multimedia

interface. The well-known tcp port number 575 has been assigned by

IANA to the VEMMI protocol [13].

A description of the VEMMI standard along with its last approved

version is publicly available on the Web: see the URL

http://www.etsi.fr/ecs/projects/vemmi/vemmi.htm). A presentation of

VEMMI can be found on http://www.mctel.fr/VEMMI/vemmien_intro.html

2) VEMMI URL scheme utility and operability:

- VEMMI service selection: A VEMMI multimedia server will listen on

its VEMMI well-known port for incoming connections. The server

could of course be engaged in many simultaneous connections, and

after a connection is established, the terminal must be able to

select the desired VEMMI application, as a same system may host

different VEMMI applications.

The best mechanism to fully describe the VEMMI service to activate

is the URL mechanism.

- Reporting user action to a remote server: The VEMMI protocol

establishes a continuous TCP/IP link between the terminal and the

server during the whole user session. During a ...
