Low bandwidth transmission
First Claim
1. A method of displaying data to a user at a user station comprising:
- providing a mass storage medium to said user station that contains said data;
establishing a communication channel between said user station and a server;
sending queries relating to metadata index categories established for said data, said queries sent from said user station over said communications channel to said server;
obtaining pointers from a metadata index located at said server that indicate the location of data on said mass storage medium that corresponds to said queries;
using said pointers to access data from said mass storage medium.

Abstract
Disclosed is a system that is capable of providing high resolution video data using a low bandwidth communications channel. A local mass storage device such as an optical storage disk is sent to a user. Data may be stored on the disk in a random fashion. The user is connected to a server through a low bandwidth connection and makes queries based upon metadata index categories. Pointers are provided by the server over the low bandwidth data communications channel to the user. The user employs the pointers to access the high resolution data provided on the local mass storage device. The pointers can be provided over the low bandwidth communications channel at a rate sufficient to allow display of the data at the user'"'"'s computer. The system can be implemented for various marketing applications, pay-for-view applications, training applications, video or audio conferencing, etc. The system can be employed over the Internet, intranets, managed networks, RF networks, optical networks, etc.

5. A system for displaying data to a user at a user station comprising:
-
a communications channel;
a local mass storage device containing data to be displayed;
an input device for generating queries regarding the data that is to be displayed;
a computer coupled to said display, said input device, said local mass storage device and said communications channel that transmits said queries over said communications channel, receives pointers in response to said queries, accesses data on said local mass storage device corresponding to said pointers and displays said data on said display that has been accessed on said local mass storage device;
a server coupled to said communications channel that receives said queries, obtains pointers from a metadata index corresponding to said queries and transmits said pointers across said communications channel to said user station. - View Dependent Claims (6, 7, 8)
