摘要： Provided is a system and method for integrating a cable modem with a host customer premises equipment, such as a computer or set top box. An interface is provided which receives data packets from the cable modem of any manufacturer and transmits the data packet to a media access control layer. The media access control layer determines the destination of the data packet and forwards it to that destination, which may be the cable modem or may be the host computer of the cable modem or any other customer premises equipment networked with the host computer. The interface also receives data packets from the media access control layer and transmits the data packets to the cable modem for transmission upstream. The interface abstracts the control of the cable modem to the media access control layer. The system maintains a protocol stack for the cable modem that is separate from the protocol stack associated with the operating system of the host computer. The cable modem and the host computer are separately addressable by the cable network. Furthermore, the cable modem shares the processor and resources of the host computer.

摘要： Automatic compilation of address filter information permits a cable modem to route incoming data packets to destination devices. A cable modem uses address filter information, such as for example, a list of addresses of communication devices that have previously registered with the cable modem, to identify incoming data packets that are addressed to communication devices associated with the cable modem. Incoming data packets with addresses that are not in the address filter information are filtered out. However, the cable modem may have insufficient filter information, when, for instance, a new communication device is associated with the cable modem. In order to automatically register communication devices associated with the cable modem, the cable modem inspects the source addresses of outgoing data packets. If the source address is not included in the address filter information, the source address is added.

摘要： A computer system that hosts a cable modem is described. The cable modem may be used to send and receive messages over the Internet using a cable network managed by a cable operator. Unlike external modems, the cable modem uses the same CPU and memory that are used by the computer system's operating system. However, the cable modem has a different network address than the computer system. When the cable modem receives a data packet having the network address of the cable modem, a cable modem driver forwards the packet to a protocol stack for the cable modem. When the cable modem receives a data packet having the network address of the computer system, the packet is forwarded to a different protocol stack for the computer system. Since the protocol stacks of the cable modem and computer system are different, direct communication from the computer system to the cable modem is not permitted.

摘要： Automatic compilation of address filter information that permits a cable modem to appropriately route incoming data packets to destination devices is described. Cable modems use address filter information to identify incoming data packets that are addressed to communication devices associated with the cable modem. The address filter information might be, for example, a list of addresses of communication devices that have previously registered with the cable modem. On occasion, the cable modem may have incorrect or insufficient or incomplete filter information when, for instance, a new communication device is added to a group of networked communication devices associated with the cable modem. In order to automatically recognize associated communication devices that are to be registered with the cable modem, a cable modem driver inspects the source address of outgoing data packets. If the source address is not included in the address filter information, the source address is added to the address filtering information. Subsequently, if an incoming data packet addresses the associated communication device, the cable modem driver allows the data packet to be passed through to the communication device.

摘要： Virtual display layers are associated with each process within a programmable set top box requiring access to a shared front panel display therein. An ordered set of virtual display layers is used to determine the information that is ultimately displayed on the shared display device. The shared display device includes a plurality of selectively controllable light emitting diode (LED) elements located on the front panel of the set top box. These LED elements correspond to data defined in the virtual display layers. The data includes flag data that associates certain properties with an element, mask data that identifies if the element is visible (e.g., opaque) or not visible (e.g., transparent) to the process, and context data that sets the state or status of the element (e.g., ON/OFF). A composite display layer is created using applicable data from the ordered set of virtual display layers. The resulting composite display layer provides the data that defines the information displayed via the display device.

摘要： Methods and arrangements are provided that significantly reduce or otherwise minimize the amount of NVRAM required within a given computing device. For example, a novel data structure and management scheme are provided in a manner that allows an NVRAM sector-based memory to appear as providing significantly more storage space than it physically has. This is accomplished by mapping a higher number of virtual sectors to a fewer number of physical sectors. Data written to a plurality of virtual sectors is compressed and written to physical sector(s). The information needed to associate the virtual and physical sectors can be maintained in a virtual sector table within less expensive RAM. If power is lost and the virtual sector table is no longer available in the RAM, then on power-up the virtual sector table is recreated based in information that is imbedded within the stored data structure in physical sectors of the NVRAM. The scheme promotes data integrity by carefully controlling the compression and decompression processes and providing data and operational step backup information to insure that data within the NVRAM is not lost by a sudden power loss, etc.

摘要： An interactive television system is provided with an interactive information system by which channels or services interact together. The information system provides informational messages that prompt a user to select an associated channel or service. If selected, the system transfers control to the selected channels or services. If necessary, information associated with the informational messages is provided to the selected channel or service. In a preferred embodiment the informational messages are sequentially displayed video segments. The video segments may be associated with other channels or services in the interactive viewing system. The user may use an input device, by depressing a single button, and launch another channel or service that is associated with the currently displayed video segment.
