AI Technical Summary

Benefits of technology

[0012]Preferably the managing means provide program data for information retrieval to the end device, so that an end device will be downloaded with such program data from the system. This feature provides the additional advantage that the end device only needs to include very little software for starting up purposes etc.
[0021]To prevent time delay even in less agile memory means of the storage medium unit, preferably video and / or audio data is divided in a predetermined number of data groups arranged in a sequence different from the original sequence.

Problems solved by technology

In this known system it is however virtually impossible to upscale the system after it has been established e.g. by a distribution company.

Embodiment Construction

[0040]The following description in which reference is made to the figures, describes a combination of hardware and software; it should be understood that some hardware components may be combined into a single hardware component such as a CPU where functions are time multiplexed. It should also be understood that connections between logic (software) units can be more complex than is shown schematically in the figures.

[0041]FIG. 1 shows an entire configuration of a preferred embodiment of an interactive communication system according to the present invention, comprising: an ATM switch 1 (as example only: ForeRunner™ ASX-200 of Fore Systems Inc., Warrendale, Pa., USA); storage medium units 20 (SMU); end devices 40; a system manager 60 and navigation devices 30. ATM switch 1 connects the storage medium units 20, the end devices 40, the system manager 60 and the navigation devices 30 to each other, selectively, by using virtual channel connections and data is transferred to and from thes...

Abstract

The present invention provides a system for serving information data such as video data to one or more users, comprising: one or more storage medium units for storing data of said information data; one or more end devices for receipt of said information data by the user; managing means for managing distribution of said data to said end device, the managing means being capable of receiving demand data form said user and related to data selected by the user in the end device, and which managing means output distribution control data including channel information of the selected information data and routs information from the end device; and least one ATM switch for connecting the storage medium unit, the end device and the managing means, and for routing the data from the storage medium unit and the distribution control data from the managing means.

Description

BACKGROUND OF THE INVENTION[0001]Conventional cable tv systems deliver video data from a distribution company through a cable to monitors of a number of viewers. Although nowadays many programs are distributed through many channels by each cable tv company, the user or viewer has to wait until the desired program is started and transmitted through a selected channel.[0002]Recently, also interactive video systems have been proposed. In such interactive video system a viewer can chose a desired movie to be displayed on the monitor of said viewer. In such video-on-demand system a direct connection to the monitor or end device of a user is established, whereafter a demanded movie can be viewed by the end user.[0003]In this known system it is however virtually impossible to upscale the system after it has been established e.g. by a distribution company. When the number of members for such a system increases and the number of demanded videos is increased, a new interactive video system ha...
