Abstract

The invention relates to an arrangement (100) comprising a mobile device (110) and an auxiliary rendering device (120). The mobile device (110) receives content from a content server (101) via a transcoding proxy (104) and can render it by itself, or relay it to the auxiliary rendering device (120). The mobile device (110) adapts the primary communication session to the capabilities of the auxiliary rendering device (120). Preferably the mobile device (110) receives an assistance message comprising information on the capabilities of the auxiliary rendering device (120), and relays this to the transcoding proxy (104) so that the content can be transcoded to a format suitable for the auxiliary rendering device (120). The mobile device (110) can perform a handover to a second auxiliary rendering device (121) if necessary.

FIG. 3

Claims

1. A mobile device (110) comprising primary communication means (201) for establishing a primary communication session via a transcoding proxy (104) with a content server (101), and auxiliary communication means (202) for establishing an auxiliary communication session with an auxiliary rendering device (120), characterized by means for adapting the primary communication session to the capabilities of the auxiliary rendering device (120).

2. A mobile device (110) as claimed in claim 1, characterized by rendering means (203) for rendering content received in the primary communication session, and rendering control means (205) for examining the content and redirecting the content to one of the rendering means (203) and the auxiliary communication means (202) in dependence on the examination, whereby the auxiliary communication means (202) are arranged for transmitting the content via the auxiliary communication session for rendering by the auxiliary rendering device (120).

3. A mobile device (110) as claimed in claim 1, characterized in that the auxiliary communication means (202) are arranged for receiving an assistance message from the auxiliary rendering device (120), the assistance message comprising information on the capabilities of the auxiliary rendering device (120), and for establishing the auxiliary communication session in response to the assistance message, and the primary communication means (201) are arranged for transmitting said information on the capabilities to the transcoding proxy (104).

4. A mobile device (110) as claimed in claim 3, characterized in that the auxiliary communication means (202) are arranged for transmitting an assistance request to at least one auxiliary rendering device (120).

5. A mobile device (110) as claimed in claim 4, characterized in that the primary communication means (201) are arranged for receiving a communication request for establishing the primary communication session, and the auxiliary communication means (202) are arranged for transmitting the assistance request in response to receiving the communication request.

6. A mobile device (110) as claimed in claim 4, characterized in that the auxiliary communication means (202) are arranged for transmitting the assistance request when a level for the quality of a previously established auxiliary communication session drops below a predetermined value.

7. A mobile device (110) as claimed in claim 3, characterized in that the auxiliary communication means (202) are arranged for ending the auxiliary communication session and establishing a further auxiliary communication session in response to receiving a further assistance message from a further auxiliary rendering device (121), said further assistance message comprising information on the capabilities of the further auxiliary rendering device (121), and in that the primary communication means (201) are arranged for transmitting said information on the capabilities to the transcoding proxy (104) in response to receiving the further assistance message.

10. An arrangement (100) comprising a mobile device (110) as claimed in any of the claims 1-7, and an auxiliary rendering device (120) as claimed in claim 8 or 9.

8. An auxiliary rendering device (120) comprising mobile device communication means (210) for establishing an auxiliary communication session with a mobile device (110), and rendering means (211) for rendering content received in the auxiliary communication session, characterized in that mobile device communication means (210) are arranged for transmitting an assistance message comprising information on the capabilities of the auxiliary rendering device (120) to the mobile device (110).

9. An auxiliary rendering device (120) as claimed in claim 8, characterized in that the mobile device communication means (201) are arranged for transmitting the assistance message in response to receiving an assistance request from the mobile device (110).
