摘要： A method and system control a return path to a source system in an interactive television environment. At the source system, a hint is generated based on information associated with the interactive television environment; and at the source system, the hint is broadcast to a plurality of receiver systems. Each receiver system determines whether to utilize the return path based on the hint.

摘要： The present invention concerns a system and a method of choosing an item by a user out of a long list (1) of items appearing on a screen (2) displaying said list, wherein the user scrolls through said list by moving a cursor along said list, said cursor designating a focused item and moving automatically from said focused item to a following one at an auto-repeat rate defining an auto-repeat period, if an action on a next item key by the user is maintained. The auto-repeat rate is periodically slowed down on predetermined items, termed sticky items, in order to give additional time to the user to absorb visual feedback on said sticky items.

摘要： A system to enable authoring of content within an interactive television environment communicates, from a source system, television content to a receiver system, the television content to be presented to a user by the receiver system. Authoring data, associated with the television content, is also communicated from the source system to the receiver system. An authoring application is communicated from the source system to the receiver system, the authoring application being executable by the receiver system to enable the user to author content utilizing the authoring data. The authoring application may include messaging logic to enable the inclusion of the content in a message.

摘要： A chat room is broadcast in an interactive television environment for lurking 'in' a chat room, without the need for establishing a back channel connection. The present invention provides a mode of chat room broadcasting and communication that can be easily handled by a client device, typically a set top box (STB) processor, an interactive television server and its subscriber clients. The present invention broadcasts chat rooms to clients who may either connect through a back channel to participate in a chat room or simply lurk, that is, to watch the chat room content and discussion in the broadcast without participating or registering in the chat room.

摘要： A common communication language that can address all the applications running in a multitude of set top boxes (STBs) or client devices and application servers. The present invention, DATP protocol encapsulates a Meta language that provides a generic portable communication application programmer interface that requires light process or utilization and is well suited for a typical STB possessing limited processing power. DATP requires relatively few processing cycles compared to typical Internet communication protocols. DATP reduces the overhead of the communication protocol handler at the STB and makes the communication protocol handler common for all STBs applications. The preferred DATP protocol is portable for all STBs since it is written in a native language that interfaces with the underlying operating system of the STB. A SGW (SGW) performs as a DATP server. The SGW translate between DATP messages and standard communication protocols. SGW enables SP clients at STBs utilizing DATP to communicate with service applications using a variety of communication protocols. A content converter is provided to convert standard Web content into content suitable for display on a client-viewing device, e.g., a TV.
