摘要:
According to the present invention, a method for receiving a broadcast service comprises the following steps: receiving service signaling data corresponding to a non-real-time service object; determining a consumption model for the non-real-time service object based on the service signaling data; if the consumption model of the non-real-time service object is determined as a trigger declarative object, receiving and storing the non-real-time service object according to a preset method; receiving a first packetized stream; extracting a trigger including a trigger action and a trigger time from a payload of the first packetized stream; and performing the trigger action for said stored non-real-time service object at the time designated by said trigger time.

A method and apparatus for receiving a broadcasting signal for a real-time broadcasting service and a non-real-time broadcasting service are disclosed. The apparatus for receiving the broadcasting signal includes a receiving unit, a storage medium, a first processor and a second processor. The receiving unit receives and displays a broadcasting service in real-time. The first processor receives and decodes non-real-time content based on reception time information and identification information included in first signaling information, and stores the decoded non-real-time content in the storage medium. The second processor reads and presents the non-real-time content from the storage medium based on presentation time information and the identification information included in second signaling information, and displays the broadcasting service in real-time.

The invention relates to a method for broadcasting structured data towards mobile terminals (10) in a territory that comprises a plurality of regions (R1, R2), wherein said method comprises the steps of assembling the structured data in transport streams (PID1, PID2), and of broadcasting each transport stream in one of the regions, the assembling step being carried out by separating, in separate transport streams (PIDO, PID1, PID2), the structured data (SSN) to be broadcasted over the entire territory and the structured data (SSR1, SSR2, SSR1 O1, SSR1 O2, SSR2O1, SSR2O2) to be broadcasted in a single region (R1, R2) of the territory.

The invention relates to a method for the temporal synchronisation of data packets of at least one media data flow (AS, VS) comprising scene data files (A-E) describing at least one scene and/or the data packets of said data files, in a unidirectional broadcast system (1). The data packets of the media data flow (AS, VS) are each provided with a first time mark relating to a first reference time (ZSl, ZS2), and the scene data files (A-E) and/or the data packets thereof are each provided with a second time mark relating to a second reference time (ZS3). At least one time mark allocation data flow (SRA, SRV, SRS) is transmitted from the transmitter (2) to the receiver (3), the first time marks of the media data flow (AS, VS) and the second time marks of the scene data files (A-E) and/or the data packets thereof being respectively associated with a third time mark relating to a third reference time (ZS*).
摘要:
A system and method for allowing viewers to acquire personalized viewer feedback data (121) from a DVB broadcast stream when running an iTV application (130) in an MHP (or OCAP) broadcast system (100, 300). In one embodiment, the system and method provides a way to address specific viewers of an MHP (or OCAP) broadcast system using a combination of a DVB broadcast channel (116) and either a direct or indirect 'return' channel (220) without the need for a dedicated backchannel.

An aspect of the invention provides an efficient transportation of ESG fragments to a receiver through the formation of containers. A container comprises at least one ESG fragment, but may contain a plurality of fragments. A fragment may be also carried by more than one container. Aspects of the present invention utilize a simple and extensible header structure apart from the fragments and independent of the type and format of the individual fragments. In an aspect of the present invention, compression is applied over the entire container, including the fragments and any headers. In an aspect of the present invention, a 3GPP metadata envelope is carried within the container without the need for unnecessary repetition of parameters, such as for example, version, validity time, and identification. In an aspect of the present invention, a simplified container system allows for the updating of previously received fragments.

A packet encapsulator includes a filter module that identifies one or more carousel packets from a plurality of received packets. These one or more carousel packets are then stored in a packet buffer. The packet encapsulator also includes a channel queue for enqueuing packets for transmission across a broadcast transmission medium. For instance, the channel queue also receives the forwarding packets from the filter module. The channel queue also receives the one or more carousel packets from the packet buffer when at least a predetermined amount of available bandwidth exists in the broadcast transmission medium. The broadcast transmission medium may be a digital broadcast network such as a DVB handheld (DVB-H) network or a DVB terrestrial (DVB-T) network. Alternatively, the broadcast transmission medium may be a cable network.

The present invention provides a method for generating a digital program having at least one interactive application, said interactive application is based of at least one data object, said method comprises: first, receiving setting on the sharing characteristic of said data object, then generating a corresponding interactive application according to said setting, finally, associating the generated interactive application with said digital program. The setting of said sharing characteristic includes "sharable" and "non-sharable". The present invention adds a sharing characteristic parameter to each data object in an interactive application at the transmitting end , so that corresponding processing could be easily performed at the receiving end according to the sharing characteristic of each data object.

Methods and systems for transmitting electronic service guide (ESG) data to a mobile terminal are described. The method for delivery of ESG data comprises steps of receiving ESG data, encapsulating metadata associated with the ESG data to generate a new ESG object, replacing a current ESG object with the new ESG object, transmitting the new ESG object in a carousel, and transmitting a notification of a change in the carousel. Another method for receiving ESG data comprises steps of receiving a notification of a change in a carousel, receiving a new ESG object in the carousel, replacing a current ESG object with the new ESG object, extracting metadata associated with ESG data from the new ESG object, storing the ESG data and metadata, and updating an ESG on a mobile terminal with the ESG data.
