Appl. No.:

09/528580

Inventors:

Michael R. Colligan - Sunnyvale CA
Yong Ho Son - Palo Alto CA
Christopher Goode - Menlo Park CA

Assignee:

Diva Systems Corporation - Redwood City CA

International Classification:

H04N 7167

US Classification:

380200, 713160

Abstract:

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.

725107, 348192, 348180, 714712, 714 48, 714 6, 714 2, 370216, 370225

Abstract:

An interactive information distribution system according to the present invention includes a session control manager having a defective channel detection module, a channel re-allocation module, and a replacement-signaling module. The session control manager is coupled to receive signals from the plurality of set top boxes, and coupled to control the digital video modulators and the assignment of communication channels to nodes. The defective channel detection module receives signals from the plurality of set top boxes, and based on the error rate and other factors determines if any of the communication channels used by the digital video modulators are defective. Upon determining that a particular communication channel is defective, the defective channel detection module signals the channel re-allocation module. The channel re-allocation module re-allocates the streams being transmitted over the defective communication channel so that they are transmitted over the other unaffected and non-defective communication channels. The replacement signaling module also identifies the defective digital video modulator and transmits this information to the network management system which in response follows a pre-defined procedure such as paging service personnel to replace the defective digital video modulator.

International Classification:

H04L 900

US Classification:

713150, 380200, 725 31

Abstract:

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.

International Classification:

H04N 5445

US Classification:

725 61, 725 40, 725 5, 725 87

Abstract:

A method and apparatus for providing subscription-on-demand (SOD) services for a interactive information distribution system, where a consumer may subscribe to packages of on-demand programs for a single price and view the programs in the subscribed package at any time for no additional cost. The apparatus and method are embodied in a combination of software, which provides a so called navigator, and hardware, including a subscriber terminal that provides certain functionality for the navigator and service provider equipment that supports the functionality of the terminal. As such, graphical user interface functionality is distributed between the service provider equipment and subscriber equipment (subscriber terminal). Such distribution provides an enjoyable, real time interactive process for accessing SOD services that allows the subscriber to rapidly identify and access a subscription service. In addition, a non-subscriber of a particular service is quickly identified and provided the opportunity to, through the use of a graphical user interface, subscribe to the programming provided by the system.

DIVA Systems Corporation - Redwood City CA

International Classification:

H04N 7173

US Classification:

725 95, 725116, 725126

Abstract:

An information delivery system provides programming, such as video programming, by dynamically allocating the programming to channel slots, based on the availability of the channel slots. Programming with high viewership statistics is transmitted substantially continuously and programming with lower viewership statistics is transmitted âon-demandâ in response to requests by users by way of a subscriber station. The subscriber stations maintain a map, provided by a corresponding session control manager, of currently available and currently transmitted channels. The information delivery system, in a preferred embodiment, takes the form of a Hybrid Fiber Coaxial (HFC) system.

US Classification:

725 88, 725 91, 386 68

Abstract:

A demand television system comprising a broadcast encoder and a storage encoder. The broadcast encoder encodes a real-time video frame sequence to form a broadcast bitstream and broadcasts the broadcast bitstream to a plurality of subscriber equipment, while simultaneously the storage encoder encodes the real-time video frame sequence to form a storage bitstream that is stored in an information server. The subscriber equipment decodes the broadcast bitstream to display the broadcast program. At any time, the subscriber equipment may request to review the information previously displayed in the broadcast bitstream. As such, the storage bitstream is transmitted to the subscriber equipment. The storage bitstream facilitates standard play of the previously broadcast information as well as trick play such as fast forward and fast reverse functions.

Abstract:

A method and apparatus for providing an interactive menu structure within an interactive information distribution system. The menu structure is embodied in a combination of software, which provides a so-called navigator and a set top terminal that provides certain functionality for the navigator and a video session manager which provides support functionality for the set top terminal. The menu structure has each menu (e. g. , menu instructions, graphics and video) contained in downloadable applets which are sent upon request from the service provider equipment to the set top terminal for display. As such, the navigator functions are actually distributed between the service provider equipment and the subscriber's equipment. Such distribution provides an enjoyable, real-time interactive session that allows the user to rapidly navigate through a plethora of menus to find particular information, which they desire to view.

Abstract:

An interactive information distribution system includes service provider equipment for generating an information stream that is coupled to an information channel and transmitted to subscriber equipment. The service provider also generates a command signal that is coupled to a command channel and transmitted to the subscriber equipment. The service provider also receives information manipulation requests from the subscriber via a back channel. A communication network supporting the information channel, command channel and back channel is coupled between the service provider equipment and the subscriber equipment.
