Abstract

A content distribution system is described in which indicia defining a level of copyright control are encapsulated together with content to which it relates in a datagram for a delivery over a network. Depending on the level of copyright control defined by the indicia, a terminal receiving the content is restricted in the operations it can carry out on the content including saving, reading and forwarding the content.

Claims

1. A method of receiving content including indicia representative of allowable operations in respect of said content, comprises receiving said content into a first memory, generating a list of allowable operations in relation to said content from said indicia and displaying said list to a user.

2. A method as claimed in claim 1, wherein transfer of said content to a second memory is included in said list of allowable operations.

3. A method as claimed in claim 1, wherein said first and second memories are respectively volatile and non-volatile.

4. A computer readable medium having stored thereon computer executable code for execution when loaded on a computer, wherein the computer is operable in accordance with said code for receiving content including indicia representative of allowable operations in respect of said content via performing steps comprising:

receiving said content into a first memory;

generating a list of allowable operations in relation to said content from said indicia; and

displaying said list to a user.

5. The computer readable medium according to claim 4, wherein transfer of said content to a second memory is included in said list of allowable operations.

6. The computer readable medium according to claim 4, wherein said first and second memories are respectively volatile and non-volatile.
