Abstract: A system and method for providing feedback formats and transport protocol extensions to support interactivity between a rich media client and a rich media server. The present invention provides for feedback formats and protocol extensions for protocols such as SMS, MMS, HTTP and RTSP. These feedback formats and protocol extensions may be used for dynamic menus, rich media players, user voting situations, video/audio selection services, remote user interfaces, and other applications.

Abstract: An extension to the ISO Base Media File Format to support ALC as a broadcast protocol. The present invention also provides for the extension of the ESG to include metadata specific to the transport of SVG over mobile broadcast/multicast networks. A “BMFDP hint track” is introduced in the container file format, with the required file metadata being in these hint tracks. The present invention can be used in applications such as the preview of long cartoon animations, interactive Mobile TV services, live enterprise data feeds, live chat services, and karaoke programs.

Abstract: In a RTP stream having a plurality of FEC frames containing source blocks of media packets, random access points are inserted in front of the source blocks so as to allow a media decoder to decode the media packets as soon as FEC decoding is finished. In particular, the media packets contain forward error correction (FEC) source blocks for a multimedia broadcast/multicast-based streaming service content. As the multimedia broadcast/multicast streaming service includes dynamic interactive multimedia scene content where the source RTP packets of different media along with the FEC RTP packets are transmitted as separate RTP streams, the inclusion of the random access point facilitates immediate rendering of the dynamic interactive multimedia scene content after FEC decoding, thus reducing the tune-in latency.

Abstract translation: 在具有包含媒体分组的源块的多个FEC帧的RTP流中，随机接入点插入在源块前面，以便在FEC解码完成时允许媒体解码器解码媒体分组。 特别地，媒体分组包含用于基于多媒体广播/基于组播的流服务内容的前向纠错（FEC）源块。 由于多媒体广播/多播流服务包括动态交互式多媒体场景内容，其中不同媒体的源RTP分组连同FEC RTP分组作为单独的RTP流传输，所以包含随机接入点有助于立即呈现动态交互多媒体 FEC解码后的场景内容，从而降低了调入延迟。

Abstract: A system and method for partitioning XML-based content into fragments, where transport packets are generated for encapsulating the fragments and streaming the encapsulated fragments to a receiver, such as a mobile device. Fragmentation of the XML-based content can be performed either with or without regard for any underlying XML syntax or structure. In either case, certain relevant fragmentation information is encapsulated with the fragmented XML-based content in the transport packets that allow for various reconstruction, error concealment, and retransmission schemes for presenting the streamed XML-based content on/to the receiver.

Abstract translation: 一种用于将基于XML的内容分割成片段的系统和方法，其中生成用于封装片段的传输分组并将封装的片段流式传输到诸如移动设备的接收器。 可以使用或不考虑任何底层XML语法或结构来执行基于XML的内容的分段。 在这两种情况下，某些相关的分段信息被封装在传输分组中的基于片段的基于XML的内容，这些内容允许各种重建，错误隐藏和重传方案，用于在接收器上呈现流式的基于XML的内容。

Abstract: An approach is provided for providing perspective-based content placement. A content placement platform processes and/or facilitates a processing of one or more models of one or more objects associated with a geographical area to cause, at least in part, a decomposition of the one or more models into one or more simplified surfaces. The content placement platform further causes, at least in part, a selection of one or more portions of the one or more simplified surfaces as one or more content placement layers based, at least in part, on one or more viewpoints, with the one or more content placement layers supporting a perspective-based rendering of one or more content items associated with the one or more objects.
