Abstract:
1. A method for outputting A/V streams onto a screen in response to a user's request by a home network which includes a server for outputting audio/video streams and plural renderers connected to the server through a home network, comprising: a step in which a renderer connected to a server requests A/V streams; a step in which the server judges whether A/V streams can be outputted in response to the request from the renderer; and a step in which the server provides the A/V streams to the renderer sequentially or simultaneously if the A/V stream can be outputted, or outputting a server unavailableness message to the renderer if the server judges that the A/V streams cannot be outputted, wherein, in the step of judging whether A/V streams can be outputted, the server compares transmission time of entire A/V streams and A/V stream transmission time according to a defined reproduction capability of the server required for reproducing A/V streams, and then judges whether the A/V streams can be outputted, and wherein the A/V stream transmission time signifies total amount of time obtained by adding the a seek time taken for a header to move to an address where the A/V stream is positioned, a head activation time taken for the header to select a track in which the A/V stream is stored, a rotation latency time taken for the header to be positioned at a desired sector, and a time taken for the A/V stream read through the header to be transferred to the memory.
