1. A method for rendering at least one of audio, video and computer graphics content, said content being delivered by a serving device and being comprised in a plurality of streams relating to different perspectives of the content, said method comprising: receiving, on an input-output device configured to receive user input and render video content, a user request for the content, the user request specifying a new perspective to be rendered on the input-output device that is different from a current perspective rendered on the input-output device; allocating, in response to said user request, a portion of at least one of processing and memorizing resources of said input-output device for rendering of the requested content, wherein the allocated portion is chosen such that remaining resources of said input-output device are sufficient for maintaining at least the input-output device's capability to receive a subsequent user request and to react thereon with a predetermined response time; determining that an amount of resources required for rendering the requested content within a predetermined rendering quality and/or within a predetermined rendering time exceeds the allocated resources, and determining a degree of pre-rendering required for meeting at least one of said predetermined rendering quality and said predetermined rendering time, wherein the pre-rendering comprises at least parts of a blending process for creating a transition sequence between said current perspective and said new perspective; pre-rendering the content on the serving device according to the determined degree of required pre-rendering only when the required resources exceed the allocated resources at the input-output device by the determined amount of resources required, and delivering the pre-rendered content from the serving device to the input-output device, and using the allocated resources for finalizing the rendering of the content on the input-output device, wherein the finalized rendered content comprises a portion according to the current perspective, a portion according to the transition sequence, and a portion according to the new perspective.

2. The method of claim 1 , wherein determination that the amount of resources required for rendering the requested content within said predetermined rendering time exceeds the allocated resources and determination of the degree of pre-rendering are performed on the serving device, said method further comprising delivering an indication of the allocated resources from the input-output device to the serving device.

3. The method of claim 1 , wherein determination that the amount of resources required for rendering the requested content within said predetermined rendering time exceeds the allocated resources and determination of the degree of pre-rendering are performed on the input-output device, said method further comprising delivering an indication of the degree of required pre-rendering to the serving device.

4. The method of claim 1 , wherein the serving device delivers the content un-rendered in case the amount of resources required for rendering the requested content with said predetermined rendering quality and within said predetermined rendering time does not exceed the allocated resources.

5. The method of claim 1 , further comprising, prior to receiving said user request for content: receiving, at the input-output device, a user request for a service having a maintained quality of service, said quality of service guaranteeing displaying of rendered content of said predetermined quality within said predetermined rendering time; sending a subscribe request corresponding the requested service from the input-output device to the serving device; setting up the requested service at the serving device; receiving, at the input-output device, a further user request for content, sending a first content request from the input-output device to the serving device, providing the content requested by the first content request from the serving device to the input-output device; and rendering and outputting the content requested by the first content request on the input-output device, the content being said content according to the current perspective.

6. The method of claim 1 , wherein the input-output device receives content according to said current perspective and content according to said new perspective in separate broadcast streams.

7. The method of claim 1 , wherein said new perspective is a refined portion of the current perspective of the content.

8. An input-output device for outputting at least one of rendered audio, rendered video and rendered computer graphics content, said content being delivered by a serving device and being comprised in a plurality of streams relating to different perspectives of the content, said input-output device comprising: a user interface for receiving a user request for the content, the user request specifying a new perspective different from a current perspective, processing and memorizing resources; an allocation module for allocation of a portion of at least one of the processing and the memorizing resources wherein said allocation module is adapted for choosing the allocated portion such that remaining resources of said input-output device are at least sufficient for maintaining the input-output device's capability to receive user inputs and react thereon with a predetermined response time; a transmitter delivering an indication of the allocated resources to the serving device; a receiver for receiving the content from the servicing device, wherein the content is received pre-rendered only when an amount of resources required for rendering the requested content within a predetermined rendering time and/or with a predetermined rendering quality exceeds the allocated resources, and wherein the pre-rendering comprises at least parts of a blending process for creating a transition sequence between said current perspective and said new perspective; and a rendering module for finalization of rendering of the received content, wherein the finalized rendered content comprises a portion according to the current perspective, a portion according to the transition sequence, and a portion according to the new perspective.

9. The input-output device of claim 8 , wherein the receiver for receiving the content from the servicing device receives content according to said current perspective and content according to said new perspective in separate broadcast streams.

10. The input-output device according to claim 8 , wherein the content is pre-rendered such that the rendering module maintains a predetermined quality of service, said quality of service guaranteeing displaying of rendered content with said predetermined quality and within said predetermined rendering time.

11. A servicing device for delivering at least one of pre-rendered audio, pre-rendered video and pre-rendered computer graphics content to an input-output device for finalization of the pre-rendered content, said servicing device comprising: a receiver for receiving, from the input-output device, an indication of resources allocated in the input-output device for output; a processing device adapted for determining an amount of resources required for rendering the requested content within a predetermined rendering time and/or with a predetermined rendering quality; said processing device being further adapted for using the allocated resources and the determined amount of required resources for determining a degree of required pre-rendering; a rendering module for pre-rendering the content according to the determined degree of required pre-rendering only when the allocated resources are exceeded at the input-output device, wherein the pre-rendering comprises at least parts of a blending process for creating a transition sequence between a first perspective and a different second perspective of the content according to a user request received at the input-output device configured to receive user input and render video content, and wherein the pre-rendered content comprises a portion according to the first perspective, a portion according to the transition sequence, and a portion according to the second perspective; and a transmitter for delivering the content to the input-output device, wherein the content is delivered pre-rendered according to the determined degree of required pre-rendering in case the amount of resources required for rendering the requested content within said predetermined rendering time exceeds the allocated resources.

12. The servicing device according to claim 11 , wherein the degree of required pre-rendering is determined such that a predetermined quality of service is maintained, said quality of service guaranteeing displaying of rendered content with said predetermined quality and within said predetermined rendering time.
