摘要： Set-top terminals utilized in broadband broadcast networks are becoming increasingly intelligent (programmable). However, transmitting executable code, data and interactive audio/video materials through a selectively dedicated link requires an extensive, broadband point-to-point broadband network, which is prohibitively expensive to implement for large numbers of customers. The present invention provides for downloading application software and transmitting audio/video information through one channel of a digital broadcast network. The network also provides two-way, low-speed data communications capacity, e.g. for signaling and/or interactive text services. Signaling via data communication with a text server controls downloading of executable code from the digital broadcast channel into a programmable digital set-top terminal. Execution of the downloaded code in turn controls selective capture and presentation of audio and video segments received over one of the digital broadcast channels. Resident operating system and application software in the terminal provides all communication with nodes of the network. The downloaded code forms a non-resident application having a set of predetermined function calls for activating communication functions of the resident software.

摘要翻译： 在宽带广播网络中使用的机顶盒变得越来越智能（可编程）。 然而，通过选择性专用链路发送可执行代码，数据和交互式音频/视频材料需要广泛的宽带点对点宽带网络，对于大量客户来说，实现这一点是非常昂贵的。 本发明提供下载应用软件并通过数字广播网络的一个频道发送音频/视频信息。 该网络还提供双向，低速数据通信能力，例如 用于信令和/或交互式文本服务。 通过与文本服务器的数据通信进行信令控制将可执行代码从数字广播信道下载到可编程数字机顶终端中。 下载的代码的执行依次控制通过一个数字广播频道接收的音频和视频段的选择性捕获和呈现。 终端中的驻留操作系统和应用软件提供与网络节点的所有通信。 下载的代码形成具有用于激活驻留软件的通信功能的一组预定功能调用的非驻留应用程序。
