摘要:
The present invention refers to an apparatus, method and system for transmission of layered encoded multimedia signals, wherein a separator (1) separates a layered encoded multimedia signal (MS) in a base layer data stream (P) and at least one enhancement layer data stream (Q, R), each data stream including a plurality of data packets (Pxy, Qxy, Rxy) having a content sequence index. A memory (2P, 2Q, 2R) buffers the data packets of the base layer stream (P) and the at least one enhancement layer data stream (Q, R), and a scheduler (3) schedules the buffered data packets (Pxy, Qxy, Rxy) into an asynchronous data stream on the basis of a first content sequence index (CSI1), wherein data packets of said at least one enhancement layer data stream (Q, R) having a content sequence index lower than said first content sequence index (CSI1) are discarded.

An IP multicast aware switched digital method and apparatus are provided in a settop unit wherein packet streams containing reference information are multicast while a select set of program information is routed to the settop units so that multicast streams can be identified and full content can be routed individually to the settop unit for decoding. Specific or preferred embodiment applications include simultaneous output and interactive communication with a television (true video on demand), computer (Internet access), videophone and telephone.

The invention relates to a method, terminal and network or entity wherein a broadcast service is used for informing a number of users on an emergency or other situation of public interest. A specific identifier is used in a paging message for activating broadcast service in the terminals. A terminal checks a received paging message with regard to the presence of the specific identifier and when detecting the specific identifier, switches to a broadcast mode for receiving broadcast content. The received broadcast emergency content is notified and/or displayed to the users of the terminals.

The invention relates to a method and a PVR server for storing and playing back TV programmes, in particular to an improved method for operating a network PVR and to an improved PVR server (102). The inventive method consists in determining the number of users storing in the personal archives thereof a determined TV programme, which is stored in the memory (108) of the PVR server (102). When the user number is less than a predefined limit value, an erasing signal occurs to them and the programme is cleared during a configurable period of time if no user selects said programme as to be preserved.
