DISTINGUISHING BETWEEN LIVE CONTENT AND RECORDED CONTENT

摘要

Distinguishing between live and recorded content in a network (100) comprising a rendering device (110), an access device (120), and a storage device (130). The rendering device broadcasts (302) a message (115) requesting devices in the network to respond if they diffuse a content, and sets a timer. The devices respond (310) if they diffuse the content. The rendering device then determines that the content is: live (307), if it has received a response from the access device; recorded (306), if it has received a response from the storage device, but not from the access device; and illegal (305), if it has not received a response before time-out of the timer. There is further a "still live delay" (150) after diffusion of the content during which the access device responds that it is diffusing the content, and following which it may send a content release message (117) to the storage device that may then respond to request messages.
