摘要： Uplink signaling for controlling a plurality of decoders at a remote site. An uplink has a control server for controlling a storage system of the decoders at the remote site. The control server of the uplink controls the storage system by injecting at least one global control stream multiplexed with a transport stream. The transport multiplexed with the global control stream is formed at the uplink for controlling the decoders simultaneously.

摘要： A system and method for retrieval and transfer of encrypted content from a failed set-top box. When content is recorded to the storage device of a set-top box, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of the set-top box and a duplicate of the content instance key is encrypted by another public key other than the public key of the set-top. In the event the set-top fails, the encrypted content on the storage device may be retrieved from the storage device by decrypting the duplicate content instance key with the private key that corresponds with the public key that encrypted the duplicate of the content instance key.

摘要： An apparatus in a digital network receives digital packets, such as MPEG packets, included in at least one input transport stream and outputs a plurality of modulated output transport streams. The apparatus determines whether the input transport streams include packets that are for multicasting from a plurality of the modulators included within the apparatus. The apparatus also determines whether the input transport streams include unicast packets that are transmitted from only one of the output modulators of the apparatus. The apparatus identifies the unicast and multicast packets of the input transport streams and associates a modulator for each unicast packet. The associated modulator of a unicast packet is the particular modulator from which the packet is modulated and transmitted. The apparatus also associates a plurality of modulators with each multicast packet, wherein the associated plurality of modulators are the modulators from which the multicast packet is transmitted.

摘要： A system and method for encrypting and recording content to removable storage media for use by multiple set-tops. When content is recorded to the storage media, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of one set-top box and a duplicate of the content instance key is encrypted with the public key of another set-top box. Either set-top box may decrypt the content instance key with the private key that corresponds with its public key so that the encrypted content from the removable storage media may be made available in the clear.

摘要： The present invention provides methods and systems for accessing services in a television system. In one embodiment, a DHCT presents a subscriber an EPG presentation containing a plurality of selectable bi-directional services that are purchasable for a period of time and rendered to a buying subscriber on an individualized basis as offered by the cable television system. The subscriber navigates an EPG menu presentation with an input device such as a remote control device and selects a purchasable service by choosing the visual representation that corresponds to the desired service. The DHCT receives the user input, translates the selected command into an executable program call that queries service availability and, if the service is available, initiates the selected bi-directional audiovisual service on a personalized session.
