| Abstract: |
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.

First Claim:

What is claimed is:
1. In a networked system including a plurality of client systems logically connected to a plurality of server systems, and wherein at least some of the client systems are comprised of a conventional television set coupled to a control box that includes a CPU programmed to enable the television set to be used to browse and display content downloaded from one or more of the server systems, a method for protecting transmission of data in the event of a power interruption which occurs while the data is being downloaded to a client system, comprising the steps of:
- connecting a client system to one of the server systems and initiating the process of downloading data blocks to a non-volatile memory of the control box of the client system:
- automatically and without user intervention at the client system, as each data block begins to be downloaded, checking for any power interruption at the client system and updating a record of all data blocks downloaded so far;
- if a power interruption is detected, automatically and without user intervention at the client system, said CPU activating a sustaining device to enable completion of downloading and storage in the non-volatile memory of the control box of the data block that was begun at the time the power interruption was detected, and updating the record of all data blocks downloaded to that point; and
- once the power interruption is over, resuming connection of the client system to the server system and resuming downloading of the data blocks, beginning only with those data blocks not yet downloaded.
