Abstract

A video or audio play-back apparatus has a variable random play option to control a degree of randomnees of the selections made from a play list.

Claims

1. An information processing system for making content information available to a user and for allowing the user to determine a degree of random selection from among the content information, said system comprising:

a database for providing access to a plurality of content information;

a player for selecting from said database and rendering various of said content information; and

a controller for enabling a user to control a selection of content information from said database to be selected and rendered by said player, said controller comprising;

a inventory listing the content information available on said database;

a track selector for generating a playlist of various of said content information from said inventory for application of said playlist to said player;

a random generator coupled to said track selector for selectively causing said track selector to generate said playlist by randomly selecting content information from said inventory; and

a user interface for enabling a user to control said track selector, said user interface having a variable random control for controlling an amount of randomness of randomly selected content information in forming said playlist, said variable random control having a first position in which the track selector selects the content information from the inventory to form the playlist in the order in which the list of content information is stored in the inventory, a last position in which the track selector selects the content information from the inventory to form the playlist in a random order under control of the random generator, and at least one intermediate position in which the track selector selects the content information from the inventory to form the playlist partly according to the random generator and partly in the order in which said list is stored.

2. The information processing system as claimed in claim 1, wherein:

the controller, through the user interface, allows the user to indicate a plurality of sections from the content; and

the variable randomness control controls the randomness with respect to the indicated selections.

3. The information processing system as claimed in claim 1, wherein said information processing system comprises an audio jukebox.

4. The information processing system of claim 1, wherein said information processing system is implemented in a client-server architecture, wherein preparing the selection is performed on a remote server under control of the user interacting with the client.

5. The information processing system as claimed in claim 1, wherein said information processing system is implemented in a client-server architecture, wherein preparing the selection is performed on the content information downloaded from a remote server onto a user'"'"'s client.

6. A method of enabling to supply content information to a user, wherein the method allows the user to vary a degree of random selection from among the content information, said method comprising the steps of:

providing access to a plurality of content information;

selecting from said database and rendering various of said content information; and

enabling a user to control a selection of content information from said database to be selected and rendered by said player, wherein said enabling step comprises the sub-steps;

generating a listing of the plurality of content information;

generating a playlist of various of said content information from said listing, said generating being performed randomly; and

controlling an amount of randomness of said playlist generating step, said controlling having predetermined range in which at a first end of said range, said playlist generating step generates the playlist from the listing in the order in which the listing is formed, at a last end of said range, said playlist generating step generates the playlist from the listing in a random order, and at at least one intermediate position in the range, said playlist generating step generates the playlist partly in a random order and partly in the order in which said listing is formed.

7. A software program for installing on an information processing system, said software program enabling the information processing system to select content information from a database and allow a user to vary a degree of random selection from among the content information, wherein said software program causes the information processing system to perform the steps:

selecting from said database and rendering various of said content information; and

enabling a user to control a selection of content information from said database to be selected and rendered by said player, wherein said enabling step comprises the sub-steps;

generating a listing of the plurality of content information;

generating a playlist of various of said content information from said listing, said generating being performed randomly; and

controlling an amount of randomness of said playlist generating step, said controlling having predetermined range in which at a first end of said range, said playlist generating step generates the playlist from the listing in the order in which the listing is formed, at a last end of said range, said playlist generating step generates the playlist from the listing in a random order, and at at least one intermediate position in the range, said playlist generating step generates the playlist partly in a random order and partly in the order in which said listing is formed.
