摘要： In accordance with a first aspect, a remote server receives video programming in a first encrypted form and stores the video programming. After the remote server receives a request from a subscriber station for transmission of the video programming, the remote server decrypts the video programming, re-encrypts the video programming into a second encrypted form, and then transmits the video programming to the subscriber station. In accordance with a second aspect, a remote server receives video programming in a first encrypted form, decrypts the video programming, re-encrypts the video programming into a second encrypted form, and then stores the video programming. After the remote server receives a request from a subscriber station, the remote server simply transmits the video programming. In accordance with a third aspect, a remote server receives video programming in a first encrypted form and stores the video programming. After the remote server receives a request from a subscriber station, the remote server passes through the video content by transmitting the video programming. In accordance with a fourth aspect, a remote server receives pre-encrypted video programming and stores it. After the remote server receives a request from a subscriber station, the remote server completes encryption of the video programming and then transmits the video programming.

摘要： Selective encryption is provided in a process which includes: determining whether a predetermined criterion is satisfied; setting a selective encryption status field if the predetermined criterion is satisfied; and encrypting an unencrypted payload to generate an encrypted payload, and constructing a packet with the encrypted payload, if the predetermined criterion is satisfied. The predetermined criterion may be one of several criteria, each of which reduce the required amount of encryption and decryption while maintaining a high level of security. Renewable encryption is provided in a process which includes: copying a first encrypted digital video program from a remote server to a video source; decrypting the first encrypted digital video program using a first key to generate an unencrypted digital video program; encrypting the unencrypted digital video program using a second key to generate a second encrypted digital video program; transmitting the second encrypted digital video program from the video source to the remote server; and deleting the first encrypted digital video program from the remote server.

摘要： An interactive information distribution system for providing secure distribution of video-on-demand content. The interactive information distribution system includes at least one programming source for storing at least one partially encrypted video program, and a distribution center including a remote server. The remote server stores the at least one partially encrypted video program received from the at least one programming source. The remote server also processes the partially encrypted video program corresponding to a subscriber requested video program to produce a fully encrypted video program. A subscriber-side distribution network, coupled to the distribution center, causes transmission of the fully encrypted video program to the requesting subscriber.

摘要： Techniques to remotely monitor and control operations performed by one or more head-ends (or servers) in an information distribution system. In one implementation, a monitor and control unit communicates with various elements (e.g., an IPG service manager and a session manager) within each head-end to receive information relating to the operations of the head-end. This information may include status and/or indications of possible error conditions relating to (1) various operations (e.g., encoding, multiplexing, and so on) performed by the head-end, and (2) the transport streams being transmitted from the head-end. The received information may then be forwarded to one or more remote devices (e.g., pagers, cellular phones, PDAs) designated to receive the information. Response messages may also be received from the remote devices and forwarded to the appropriate head-end, which may adjust its operation as indicated by commands included in the messages.

摘要： A method and apparatus for allowing a personal computer to receive data from a computer network such as the Internet via a broadcast channel of a cable or satellite television network, while transmitting data upstream to the computer network via a telephone line. A packet processing relay agent (PPRA) forwards data at the data link layer between a one-way network adapter, such as a cable modem that receives Internet data via a cable network, and a two-way return path adapter, such as a telephone modem that communicates with Internet servers and other users via a telephone network. The system provides compatibility with TCP/IP routing/addressing conventions by forwarding upstream IP packets with a cable modem source address over the telephone modem. The PPRA can enhance functionality by incorporating higher layer functions at the data link layer.
