Serving data
First Claim
1. A data transmission system comprising:
- a data distribution unit for distributing items of data to data terminals; and
a plurality of data terminals capable of requesting items of data from the data distribution unit;
a point-to-point communication system whereby each data terminal can transmit point-to-point messages from itself to the data distribution unit; and
a broadcast communication system whereby the data distribution unit can broadcast data to all the terminals;
the data terminals being arranged to transmit requests for items of data to the data distribution unit via the point-to-point communication system, and the data distribution unit being arranged to, in response to receiving such a request, retrieve the requested item of data and transmit it via the broadcast communication system.

Abstract
A data transmission system comprising: a data distribution unit for distributing items of data to data terminals; and a plurality of data terminals capable of requesting items of data from the data distribution unit; a point-to-point communication system whereby each data terminal can transmit point-to-point messages from itself to the data distribution unit; and a broadcast communication system whereby the data distribution unit can broadcast data to all the terminals; the data terminals being arranged to transmit requests for items of data to the data distribution unit via the point-to-point communication system, and the data distribution unit being arranged to, in response to receiving such a request, retrieve the requested item of data and transmit it via the broadcast communication system. The serving device can detect frequently asked resources and initiate broadcast of such resources through the broadcasting device, eliminating all bandwidth usage for future requests of such resources.

10. A method for distributing data in data transmission system comprising a data distribution unit for distributing items of data to data terminals;
- a plurality of data terminals capable of requesting items of data from the data distribution unit;
a point-to-point communication system whereby each data terminal can transmit point-to-point messages from itself to the data distribution unit; and
a broadcast communication system whereby the data distribution unit can broadcast data to all the terminals;
the method comprising the steps of;
transmitting from a data terminal to the data distribution unit via the point-to-point communication system a request for an item of data;
