Abstract: A Simple Network Management Protocol (SNMP) agent includes logic configured to add a first object ID to a first MIB corresponding to a first software entity responsive to a request from the first software entity, and configured to add a second object ID to a second MIB corresponding to a second software entity responsive to a request from the second software entity, and logic configured to delete the first object ID from the first MIB responsive to a request from the first software entity, and configured to delete the second object ID from the second MIB responsive to a request from the second software entity.

Abstract: A fiber-to-the-home (FTTH) system transmits forward and reverse optical signals, such as video, voice, and data signals, via optical fiber, and includes a plurality of home network units. The home network units include an optical receiver for receiving at least one of the video, voice, and data signals. Included is a plurality of gain stages that are distributed throughout the optical receiver. The gain stages include a preamplifier stage, two interstage amplifiers, and a postamplifier stage. Two gain control circuits automatically adjust the gain of the video signal based upon the input power level to the FTTH optical receiver. Additionally, a tilt network performs level compensation for externally located coaxial cable. A signal is then provided to a device located within a home via the coaxial cable at the proper RF level having low noise signals.

Abstract: The present invention is suitable for use in a communications system that transmits a transport stream, such as an MPEG stream. The present invention addresses the need of generating a valid value for a duplicated packet in the transport stream. A first embodiment of the present invention interpolates between a PCR value in the duplicated packet and the PCR value in the next PCR packet. A second embodiment of the present invention copies an original packet along with its PCR value into a duplicate packet and a PCR-bearing packet. Subsequently, the present invention interpolates a new value for the original packet based on the original value in the duplicated PCR-bearing packet and the previous value in a PCR-bearing packet.

Abstract: The present invention provides a system for providing alternative services in a television system. In one implementation, a subscriber is provided an alternative service upon attempting to access an unauthorized service, thereby providing a framework for efficient control of conditional access and enhanced services. In addition, in one implementation, user device limitations or variations are handled conveniently through the same multi-purpose system for providing alternative services.

Abstract: A conditional access device is provided. The conditional access device typically includes conditional access decryption, interface, timing and control logic. The conditional access decryption logic decrypts an incoming signal for use in a consumer electronics device in accordance with previously received entitlement management messages. The interface logic receives a control signal including an entitlement management message window from a headend control system through a receiver in the consumer electronics device. The timing logic asserts an awake signal responsive to the entitlement management message window becoming active. The control logic sends a request to the consumer electronic device to activate a receiver coupled to the headend control system in expectation of receiving an entitlement management message via the control signal in response to assertion of the awake signal. The control logic also communicates the entitlement management message to the conditional access decryption logic.

Abstract: Systems and methods are disclosed for providing encrypted downstream signals to a plurality of receiver devices 130, 135, 140, where the devices 130, 135, 140 may have different decryption devices. A receiver network (i.e., a networked multimedia system) includes a splitter/isolation module (SIM) 125, a primary set-top terminal (STT) 130, and at least one remote device 135, 140. The remote devices 135, 140 communicate with the primary STT 130 via the SIM 125 over coaxial cable. Accordingly, the remote devices 135, 140 are capable of requesting and receiving stored programs via the networked multimedia overlay system. Depending upon the decryption device included in the requesting remote STT 135, 140, the primary STT 130 sends a stored program encrypted according to that decryption device.

Abstract: Disclosed herein is a system for the variable attenuation of broadband differential signals. An exemplary system of variable attenuation of broadband differential signals includes attenuation devices arranged such that an attenuation device on the positive side of the differential signal has a corresponding attenuation device on the negative side of the differential signal with both of the corresponding attenuation devices on the same semiconductor die.

Abstract: A broadband communications system uses modulation symbol transport over communications links to replace baseband or bandpass signal transport, thereby providing longer communication distances, lower communication link bandwidth, and greater signal quality. Subsequent to transporting the modulation symbols, the symbols are modulated and further transmitted over the RF transmission network.

Abstract: A system and method for minimizing timeouts when enhanced services are requested through a digital home communications terminal (DHCT) requiring discovery of a service group identification (SGID) assigned to the DHCT. A service group map (SGM) includes a plurality of entries. Each entry includes a frequency, a tabulated transport stream identification (TSID), and a SGID associated with one another. The SGM has multiple occurrences of the same frequency. Each of the entries are prioritized relative one another such that the frequencies associated with first occurrences of each SGID have the highest priority.

Abstract: A media system provides improved availability of purchasable recordable media content downloaded from a remote server. The media system preferably includes a memory with logic and a processor configured with the logic to provide a download option to a user. The processor is further configured with the logic to update the download option proximately in time if a change in download resources changes the availability of the download option.

Abstract: A digital subscriber communication terminal includes an adaptive output interface having a device key set, which, along with a subscriber device coupled to the adaptive output interface, determines a “shared secret.” The adaptive output interface uses the “shared secret” to encrypt content and transmits the content to the subscriber device coupled to the adaptive output interface. The digital subscriber communications terminal includes a processor, a memory having an encrypted device key set and an encrypted device key set decryptor stored therein and a secure element having a key decryptor. The secure element is adapted to receive the encrypted device key set decryptor and use the key decryptor to decrypt the encrypted device key set decryptor. The device key set decryptor is provided to the processor, which decrypts the encrypted device key set using the device key set decryptor, and the device key set is loaded into the adaptive output interface.

Abstract: DVD playback over Multi-room by copying to the hard drive of a primary device in a networked multi-room system (NMS). The DVD content is saved to a hard drive and can then be retrieved by any of the remote devices in the NMS by accessing the program guide or the recorded programs list. The DVD menu can be altered to include previews, contests, products, etc.
