Abstract

A device and a method for transmitting notification messages (165) and a corresponding device and method for receiving notification messages. A transmitting device (100) receives a filter definition (135) defining a filter type for use in filtering of the notification messages. The filter definition is transmitted to a terminal (160) via a broadcast installation (150). The terminal configures a filter based upon the filter definition. When a 5 notification is to be sent notification input data (145) is received and filter elements (175) are determined. The filter elements correspond to parameters derived from the filter definition. The value of the parameters correspond to the notification input data. The notification messages comprising the filter elements are generated and sent to the terminal. The terminal filters the notification messages using the filter, where the filtering is based upon the filter 10 elements.

Claims

1. A device (100) for transmitting notification messages (165) to a terminal (160), the device comprising:

a first input (130) for receiving a filter definition (135), the filter definition defining a filter type for use in filtering of the notification messages;

a second input (140) for receiving notification input data (145); and

a processor (110)

for transmitting the filter definition to the terminal;

for determining filter elements (175), the filter elements corresponding to parameters derived from the filter definition, the value of the parameters corresponding to the notification input data, the filter elements to be used during a filtering action performed on the notification messages in the terminal;

for generating the notification messages, the notification messages comprising the filter elements; and

for transmitting the notification messages to the terminal.

2. The device of claim 1 wherein the filter type defines syntax and semantics of a filter to be defined and the processor transmits the syntax and semantics of the filter to be defined to the terminal by means of the filter definition.

3. The device of claim 1 wherein the filter definition comprises a filter type identifier (600) for identifying a particular filter type and the processor transmits the filter type identifier to the terminal by means of the filter definition.

4. The device of claim 3 wherein the filter elements comprise a further filter type identifier corresponding to the filter type identifier and the processor transmits the further filter type identifier to the terminal by means of the filter elements.

5. The device of claim 1 further comprising a third input (120) for receiving configuration input data (125) and wherein the processor transmits the configuration input data in combination with the filter definition as configuration data (155).

6. The device of claim 1 wherein the processor is configured to transmit the notification messages using a protocol corresponding to Internet Protocol Datacast over DVB-H.

7. A device (160) for receiving notification messages (165), the device comprising:

a communication module (220) having a first input (210) for receiving the notification messages and for receiving a filter definition (135), the filter definition defining a filter type for use in filtering of the notification messages;

a processor (240) communicatively coupled to the communication module for configuring a filter (260) in the device based upon the filter definition;

wherein the filter is configured for receiving the notification messages in the device, the notification messages comprising filter elements (175), the filter elements corresponding to parameters derived from the filter definition, the filter elements to be used during a filtering action performed on the notification messages in the device; and

for

filtering the notification messages in the device, the filtering being based upon the filter elements.

8. The device of claim 7 wherein the communication module comprises the filter.

9. The device of claim 7 further comprising a co-processor (310) and wherein the co-processor comprises the filter.

10. The device of claim 7 wherein the filter definition comprises a filter type identifier (600) for identifying a particular filter type and the processor is configured to configure the filter to filter the notification messages based upon the filter type identifier.

11. The device of claim 10 wherein the filter elements comprise a further filter type identifier corresponding to the filter type identifier and the filter is configured to pass filtered notification messages (400) when the further filter type identifier corresponds to the filter type identifier.

12. The device of claim 10 wherein the filter elements comprises a filter element value (920) and the processor is configured to configure the filter to further filter the notification messages based upon the filter element value.

13. The device of claim 7 wherein the communication module further comprises a processor control signal (410) for controlling the operation of the processor based upon filtering of the notification messages in the device.

14. The device of claim 7 wherein the communication module is configured to receive the notification messages using a protocol corresponding to Internet Protocol Datacast over DVB-H.

15. The device of claim 7 realized as at least one of the group consisting of:

a digital video recording device;

a network-enabled device;

a conditional access system;

a portable audio player;

a portable video player;

a mobile phone;

a DVD player;

a CD player;

a hard disk based media player;

an Internet radio device;

a computer;

a television;

a public entertainment device; and

an MP3 player.

16. A method for transmitting notification messages (165) to a terminal (160), the method comprising:

receiving (1100) a filter definition (135), the filter definition defining a filter type for use in filtering of the notification messages;

transmitting (1110) the filter definition to the terminal;

receiving notification input data (145);

determining (1120) filter elements (175), the filter elements corresponding to parameters derived from the filter definition, the value of the parameters corresponding to the notification input data, the filter elements to be used during a filtering action performed on the notification messages in the terminal;

generating (1130) the notification messages, the notification messages comprising the filter elements; and

transmitting (1140) the notification messages to the terminal.

17. A method for receiving notification messages (165) in a terminal (160), the method comprising:

receiving (1200) a filter definition (135), the filter definition defining a filter type for use in filtering of the notification messages;

configuring (1210) a filter (260) in the terminal based upon the filter definition;

receiving (1220) the notification messages in the terminal, the notification messages comprising filter elements (175), the filter elements corresponding to parameters derived from the filter definition, the filter elements to be used during a filtering action performed on the notification messages in the terminal; and

filtering (1230) the notification messages in the terminal using the filter, the filtering being based upon the filter elements.
