Abstract

A device for controlling the communication in a system comprises a transmitter, a receiver and a chip module. The transmitter and the receiver are communicatively connected. The chip module is communicatively connected to the receiver and is inserted in the same. The device includes a generator for generating a communication object. The communication object comprises a parameter block in which at least one instruction is defined which defines how the communication between the receiver and the module is to be performed. The communication object further comprises a payload data block in which data is defined causing a communication between the receiver and the chip module. The device further includes a means for transferring the communication object from the transmitter to the receiver.

Claims

1. A method for controlling the communication in a system comprising a transmitter, a receiver and a chip module, wherein the transmitter and the receiver are communicatively connected and wherein the chip module is communicatively connected to the receiver and inserted in the same, comprising the following steps:

transmitting a communication object from the transmitter to the receiver, wherein the communication object comprises a parameter block in which at least one instruction is defined which defines how communication between the receiver and the chip module are to be performed, and a payload data block, in which data is defined which causes a communication between the receiver and a chip module;

interpreting the instruction within the parameter block by the receiver in order to control a communication protocol of the receiver for communicating with the chip module; and

processing the data defined within the payload data block according to the communication protocol of the receiver by the receiver, whereby the communication between the receiver and the chip module caused by the data defined in the payload data block is performed according to the communication protocol of the receiver.

2. The method according to claim 1, wherein the parameter block comprises a plurality of parameter fields, containing a plurality of parameters containing at least one of the following pieces of information:

p1 a statement of the type of communication protocol which is specific for the chip module, which is to be used for a communication between the receiver and the chip module;

an instruction of how the payload data block is to be interpreted by the receiver;

an instruction for requesting the chip module to answer to an already transferred payload data block; and

an instruction of how the receiver is to interpret the answer of the chip module.

3. The method according to claim 1, wherein the chip module is exchangeable.

4. The method according to claim 1, wherein the transmitter is a central transmitter of a conditional access system or an access control system, the receiver is a terminal device of the system and the chip module is a single chip module.

5. A device for controlling the communication in a system comprising a transmitter, a receiver and a chip module, wherein the transmitter and the receiver are communicatively connected and the chip module is communicatively connected to the receiver and inserted into the same, the device comprising:

a generator within the transmitting means for generating a communication object, wherein the communication object comprises a parameter block in which at least one instruction is defined defining how the communication between the receiver and the chip module is to be performed, and a payload data block in which data is defined causing a communication between the receiver and the chip module; and

a means for transferring the communication object from the transmitter to the receiver.

6. The device according to claim 5, wherein the parameter block comprises a plurality of parameter fields containing a plurality of parameters, containing at least one of the following pieces of information:

a statement of the type of communication protocol which is specific for the chip module which is to be used for a communication between the receiver and the chip module;

an instruction of how the payload data block is to be interpreted by the receiver;

an instruction for requesting the chip module to answer to an already transferred payload data block; and

an instruction about how the receiver is to interpret the answer of the chip module.

7. The device according to claim 5, wherein the chip module is exchangeable.

8. The device according to claim 5, wherein the transmitter is a central transmitter of a conditional access system or an access control system, the receiver is a terminal device of the system and the chip module is a single chip module.

9. Signal for transferring from a transmitter to a receiver, for controlling the communication within a system comprising the transmitter, the receiver and a chip module, wherein the transmitter and the receiver are communicatively connected and wherein the chip module is communicatively connected to the receiver and inserted into the same, wherein the signal comprises a payload data block and a parameter block, wherein data is defined in the payload data block causing a communication between the receiver and the chip module, and wherein instructions are defined within the parameter block, defining how the communication between the receiver and the chip module is to be performed.
