Apparatus and method for delivering stream in a mobile broadcast system
First Claim
1. A method for delivering a stream in a mobile broadcast system that receives stream contents of broadcast services (BCAST) from a content creation and provides the broadcast services to at least one terminal via at least one of a broadcast distribution system (BDS) and an interaction network, the method comprising:
- delivering, by a stream application function(SA), a stream comprising an attribute from the content creation to a stream delivery function (SD);
sending, by the stream delivery function, a request for bearer assignment to a BDS service distribution in order to deliver the stream;
assigning, by the BDS service distribution, bearers used for stream delivery and sending a response comprising information on the assigned bearers to the stream delivery function; and
delivering, by the stream delivery function, a BCAST streaming service to a stream delivery client function in a mobile terminal over a broadcast channel.

Abstract
A method and system are provided for delivering a stream in a mobile broadcast system that receives stream contents of broadcast services (BCAST) from a content creation and provides the broadcast services to one terminal or one group of terminals via one of a broadcast distribution system (BDS) and an interaction network. The method involves requesting assignment of a bearer in which the stream is to be delivered, assigning a bearer in response to the bearer assignment request, adapting the stream to be appropriate for the assigned bearer, and delivering the adapted stream to the terminal in the assigned bearer.

12. A method for delivering a stream in a mobile broadcast system that receives stream contents of broadcast services (BCAST) from a content creation and provides the broadcast services to at least one terminal via at least one of a broadcast distribution system (BDS) and an interaction network, the method comprising:
-
translating, by a stream application function (SA), the stream to be compatible with the broadcast service if the stream is different from a BCAST standard stream in terms of a media type and CODEC information and delivering the stream comprising an attribute from the content creation to a stream delivery function (SD); delivering, by the stream delivery function (SD), the stream to a BDS service distribution; and delivering, by the BDS service distribution, the stream to a stream delivery client function in a mobile terminal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for sending a report on stream reception at a terminal in a mobile broadcast system that receives stream contents of broadcast services (BCAST) from a content creation and provides the broadcast services to at least one terminal via at least one of a broadcast distribution system (BDS) and an interaction network, the method comprising:
-
receiving, by a stream delivery client function in a mobile terminal, a stream comprising an attribute from a stream delivery function via bearers assigned in a BDS service distribution; receiving, by the stream delivery function, a report on stream reception comprising reception quality from the stream delivery client function via the interaction network; analyzing, by the stream delivery function, the report on the stream reception; and sending, by the stream delivery function, a report on stream reception to a BDS service distribution to improve stream reception quality. - View Dependent Claims (23, 24, 25)
