    摘要： A World Wide Web browser software is implemented in a processing system housed in a set-top box connected to a television and communicating over a wide-area network with one or more servers. The browser software allows a user to navigate using a remote control through World-Wide Web pages in which a number of hypertext anchors are displayed on the television. User inputs are entered from a remote input device using an infrared (IR) link. The processing system includes a read-only memory (ROM) and a flash memory. The mask ROM and the flash memory are assigned adjacent memory spaces in the memory map of the processing system. Browser software and configuration data are stored in the flash memory. Other software and configuration data are stored in a mask ROM. The browser is upgraded or reconfigured by downloading to the box replacement software or data transmitted from a server over the network and then writing the replacement software or data into the flash memory. A mechanism is provided to temporarily maintain power to the processing system in the event power to the box is lost during downloading. The mechanism allows the writing of a current block to be completed. An indication of the current block is maintained while power is absent so that downloading can be resumed once power is restored from the last block that was written.

    摘要翻译： 万维网浏览器软件被实现在处理系统中，该处理系统容纳在连接到电视机的机顶盒中，并且通过广域网与一个或多个服务器进行通信。 浏览器软件允许用户使用遥控器通过在电视上显示许多超文本锚的万维网页进行导航。 使用红外（IR）链接从远程输入设备输入用户输入。 处理系统包括只读存储器（ROM）和闪速存储器。 掩模ROM和闪存被分配在处理系统的存储器映射中的相邻存储器空间。 浏览器软件和配置数据存储在闪存中。 其他软件和配置数据存储在掩模ROM中。 浏览器通过下载到盒子更换软件或通过网络从服务器传输的数据，然后将替换软件或数据写入闪存来升级或重新配置。 提供一种机制，用于在下载过程中在盒子功率损失的情况下暂时维持处理系统的电源。 该机制允许完成当前块的写入。 当电源不存在时，保持当前块的指示，一旦从写入的最后一个块恢复电源，就可以恢复下载。

    摘要： An interactive television system includes “connected” receiver units capable of establishing bi-directional connections to remote information stores, such as Web servers, and “disconnected” receiver units unequipped to make such connections. The system supports the use of broadcast triggers that include connectivity values indicating whether an information resource identified by a trigger refers to “connected content” or “disconnected content.” The term “connected content” refers to information resources that require bi-directional connections to remote information stores; the term “disconnected content” refers to information resources, such as a locally stored program guide, that do not require such bi-directional connections. Disconnected receiver units identify and reject connected-content triggers by examining connectivity values broadcast as part of triggers. Thus, content providers can broadcast connected-content triggers to connected and disconnected receiver units without interrupting disconnected receiver units with links to inaccessible content. Furthermore, the ability to distinguish between connected and disconnected content allows vendors who sell or lease receiver units to offer a lower level of service to those customers who do not wish to pay for the ability to access connected content.
