Abstract

The invention concerns a gateway comprising means for receiving the first frames of a digital video broadcasting service, characterized in that it comprises:

• • means for determining data representative of a time-slice,
  • means for encapsulating each of the first service frames in a second frame comprising said data representative of a time-slice, and
  • means for transmitting over a wireless local area network each second frame to a digital audio/video terminal.

Claims

1. Gateway comprising:

a receiver of first frames of a digital video broadcasting service,

a module determining data representative of time slicing,

an encapsulator encapsulating each of the first service frames in a second frame comprising said data representative of a time-slice, and

a transmitter transmitting over a wireless local area network each second frame to a digital audio/video terminal.

2. Gateway according to claim 1, wherein said gateway comprises an inserter inserting data representative of a time-slice in each second frame according to a session description protocol.

3. Gateway according to claim 2, wherein said session description protocol is of the SAP-SDP type.

4. Gateway according to claim 1, wherein the receiver of first frames of a digital video broadcasting service is associated with a wired network.

5. Gateway according to claim 1, wherein the means for receiving the first frames of a digital video broadcasting service are associated with a wireless network.

6. Gateway according to claim 1, wherein said wireless network is of the IEEE 802.11, Hiperlan, IEEE802.15 or IEEE802.16 type.

7. Gateway according to claim 1, wherein said gateway comprises a detector detecting a power saving mode of a terminal receiving said second frames so as to transmit each second frame when the destination terminal is in the listening mode.

8. Gateway according to claim 1, wherein said service is of the DVB-H type.

9. Gateway according to claim 1, wherein each second frame comprises a destination address corresponding to a single terminal.

10. Gateway according to claim 1, wherein each second frame comprises a destination address corresponding to several terminals.

11. Gateway according to claim 1, wherein it comprises a module determining audio/video terminals and a filter filtering the first service frames received, only the service frames intended for one of said determined terminals being encapsulated by said encapsulation means.

12. Gateway according to claim 1, wherein the receiver of first frames of a digital video broadcasting service are associated with a long-distance wireless broadcasting network.

13. Digital audio/video terminal, wherein it comprises:

a receiver of second frames comprising data representative of a time-slice, the second frames being transmitted over a wireless local area network, and

an extractor extracting first service frames from said second frames.

14. Method for broadcasting digital video services comprising a step for receiving the first frames of a digital video broadcasting service, wherein said method comprises:

a step for determining data representative of a time-slice,

a step for encapsulating each of the first service frames in a second frame comprising said data representative of a time-slice, and

a step for transmitting over a wireless local area network each second frame to a digital audio/video terminal.

15. Method for receiving digital audio/video, wherein said method comprises:

a step for receiving second frames comprising data representative of a time-slice, the second frames being transmitted over a wireless local area network, and

a step for extracting first service frames from said second frames.
