    摘要: A method and system for performing multicast broadcast handover in a wireless data network are disclosed. Each cell broadcasts administrative announcements over a logical channel to mobile terminals. The announcements indicate which multicast broadcasts are available in specified cells, as well as connection information for each cell. The mobile terminals may tune to a multicast broadcast as defined by the administrative announcements. While tuned to the multicast, the mobile terminal continues to receive administrative announcements. As the broadcast fades out or is otherwise interrupted, the mobile terminal can retune to the same multicast broadcast in another cell, based on the cell connection information included in the previously received administrative announcements.

    摘要: Methods and systems for providing zapping data for one or more programs transmitted using timeslicing are disclosed herein. Zapping data may be provided by a zapping data provider or server, or may be created at the mobile terminal based on received program information. Zapping data may be provided to mobile terminals via a wireless multicast network, such as a DVB-H network, using a variety of timeslicing techniques, including providing a separate zapping data stream, providing zapping data as part of the source stream, or allowing mobile terminals to derive zapping data from the source content's broadcast stream. Zapping images may be selected from I-frames of video transmissions. An IP encapsulator may synchronize broadcast streams such that I-frames are transmitted concurrently, and at the beginning of timeslice bursts.

    摘要: Systems and methods for processing and distributing legal text information allow content providers to distribute legal text to terminals receiving broadcast content. The legal text may include terms and conditions associated with content that a user may want to purchase or subscribe. Upon receiving a content selection that a user wishes to purchase, a terminal may determine whether the content is associated with legal text information. If so, the legal text may be obtained and rendered for the user. The terminal may further determine whether user consent is required and if so, prompt the user with a consent agreement. Legal text information may be obtained in a variety of manners including from a service provisioning system, from a local cache in the terminal and/or from a file delivery server. Communication of legal text information may further be conducted using messages storing legal text attributes and elements.

    摘要: A method of transmitting a service to several subscribers in a packet data network capable of individual and group transmissions. The method includes collecting requests for the service from the several subscribers, evaluating the popularity of the service, forming a group of the subscribers that have requested the service, and transmitting the service over a group transmission if the popularity of the service at least equals or is likely to equal a predetermined threshold level. The mobile node subscribers may be reached via several different access networks, in which case an optimal access network can be selected. The method is preferably implemented by a group forming unit which can be integrated or co-located with a gateway which connects the service provider's network with the Internet.

    摘要: Provided are apparatuses and methods in a digital broadcast transmission system for deducing the contents or topology of an ESG fragment, transport object, container or session. In one example, descriptors may be transmitted on a first channel that may correspond to ESG fragments transmitted on a second channel. The first and second channel can be received at a subscriber terminal. The subscriber terminal may thus be apprised of the topology of the ESG fragments to minimize the amount of information the subscriber terminal needs to receive. This provides an optimized overall retrieval of the ESG fragments.

    摘要: An electronic service guide (ESG) is provided by transmitting announcements describing multimedia sessions, such as video streams. Sessions are organised into a session directory (28) which is split into two parts: a full session directory (291) and an updated session directory (292). A first kind of announcement describes all sessions in the full session directory. A second kind of announcement describes sessions in the updated session directory. Once a client has received a description of the full session directory, it need only listen to announcements of the second type so as to learn of any updates to sessions.

    摘要: The invention provides an efficient transportation of ESG fragments to a mobile device through the formation of containers. In this sense, a container comprises at least one ESG fragment, but may contain a plurality of fragments. A fragment may be also carried in more than one container. Aspects of the present invention utilize a simple and extensible header structure apart from the fragments independent of the type and format of the individual fragments. In further embodiments, compression is applied over the entire container, including the fragments and any headers. In yet further embodiments, 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 further embodiments, a simplified container system allowing for the updating of previously received fragments is disclosed.
