Encryption Of Streaming Control Protocols And Their Headers

View page
US Patent:
7237108, Jun 26, 2007
Filed:
Jun 25, 2002
Appl. No.:
10/183130
Inventors:
Alexander Medvinsky - San Diego CA, US
Petr Peterka - San Diego CA, US
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04L 9/00
H04N 7/167
US Classification:
713160, 380200
Abstract:
A method for securely streaming real-time content from a caching server to an authorized client. The method includes the steps of encrypting an RTSP (real-time streaming protocol) message having a header and a payload, the RTSP message being encrypted in its entirety; and providing a first clear header for the encrypted RTSP message. Further, the method includes the steps of encrypting an RTCP (real-time control protocol) message having a header and a payload, the RTCP message being encrypted in its entirety; and providing a second clear header for the encrypted RTCP message. Thereafter, the encrypted RTSP message and the first clear header are transmitted, and the encrypted RTCP message and the second clear header are transmitted in order to securely stream the real-time content from the caching server to the authorized client.

Key Management Protocol And Authentication System For Secure Internet Protocol Rights Management Architecture

View page
US Patent:
7243366, Jul 10, 2007
Filed:
Mar 4, 2002
Appl. No.:
10/092347
Inventors:
Alexander Medvinsky - San Diego CA, US
Petr Peterka - San Diego CA, US
Paul Moroney - Olivehain CA, US
Eric Sprunk - Carlsbad CA, US
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
G06F 17/30
G06F 7/04
G06K 9/00
H04L 9/32
H04L 9/00
US Classification:
726 2, 726 10, 705 65, 709226
Abstract:
A digital rights management architecture for securely delivering content to authorized consumers. The architecture includes a content provider and a consumer system for requesting content from the content provider. The content provider generates a session rights object having purchase options selected by the consumer. A KDC thereafter provides authorization data to the consumer system. Also, a caching server is provided for comparing the purchase options with the authorization data. The caching server forwards the requested content to the consumer system if the purchase options match the authorization data. Note that the caching server employs real time streaming for securely forwarding the encrypted content, and the requested content is encrypted for forwarding to the consumer system. Further, the caching server and the consumer system exchange encrypted control messages (and authenticated) for supporting transfer of the requested content. In this manner, all interfaces between components are protected by encryption and/authenticated.

System For Secure Decryption Of Streaming Media Using Selective Decryption Of Header Information And Decryption Of Reassembled Content

View page
US Patent:
7251328, Jul 31, 2007
Filed:
Jan 14, 2003
Appl. No.:
10/342539
Inventors:
Joseph Diamand - San Diego CA, US
Petr Peterka - San Diego CA, US
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04N 5/937
H04N 5/935
H04N 1/393
US Classification:
380205, 380239, 380240
Abstract:
A system provides improved security in a streaming media decoder includes decryption of encoded media information at the media layer, within a decoder component of a playback device. A content source, such as an MPEG-4 media stream from a network, or a file on a local storage device, etc. that contain packetized content, and supplies encrypted and encoded media information. For example, digital sound and image information can be conveyed for presentation. A reassembler component is used to initiate decryption of a nominal amount of information needed to perform further processing at the QuickTime player. Encrypted access units are sent from the reassembler to the decoder, where the decoder causes decryption of the access unit information. This approach prevents decrypted, encoded information from being transferred from the reassembler to the decoder. Such decrypted and encoded information is especially susceptible to copying.

Scalable Pay-By-Time Technique For Secure Multicast Distribution Of Streaming Content

View page
US Patent:
7310809, Dec 18, 2007
Filed:
Mar 9, 2001
Appl. No.:
09/802421
Inventors:
Petr Peterka - San Diego CA, US
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04N 7/16
H04N 7/173
US Classification:
725 87, 725 1, 725 93, 725 97, 725100
Abstract:
A method for receiving information content from an information distribution system, wherein the information content is divided into a plurality of content portions, the method comprising: subscribing to a multicast group representing at least one content portion; and determining, at the end of a content portion, whether to subscribe to another multicast group.

Association Of Security Parameters For A Collection Of Related Streaming Protocols

View page
US Patent:
7356687, Apr 8, 2008
Filed:
May 21, 2002
Appl. No.:
10/153445
Inventors:
Alexander Medvinsky - San Diego CA, US
Petr Peterka - San Diego CA, US
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04L 9/00
G06F 9/00
US Classification:
713151, 713160, 726 14
Abstract:
In a client-server system employing protocols such as RTP (real-time protocol), RTCP (real-time control protocol) and RTSP (real-time streaming protocol) for communicating real-time data stream, a method for using the same security parameters to secure by encryption and/or authentication, communication of the real-time data stream. The method includes establishing two or more security parameters for securing communications during the streaming session; establishing a session identifier associated with the security parameters; transmitting, from client to server, an RTSP message for requesting the real-time data stream, the RTSP message being secured with the security parameters; establishing a streaming session for streaming an RTP message containing the real-time data, the RTP message being secured with the security parameters; transmitting, from client to server, an RTCP protocol message containing statistics relating to the streaming session, the RTCP message being secured with the security parameters, and exchanging any one or more additional RTSP, RTP and RTCP messages in any order, each message being secured with the security parameters which are identifiable with the session identifier.

Application Programming Interface (Api) For Accessing And Managing Resources In Digital Television Receiver

View page
US Patent:
7487534, Feb 3, 2009
Filed:
Oct 7, 1999
Appl. No.:
09/830754
Inventors:
Petr Peterka - San Diego CA, US
Branislav N. Meandzija - La Jolla CA, US
Geetha Mangalore - San Diego CA, US
Kurt Zaiser - San Diego CA, US
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H04N 7/173
H04N 7/16
US Classification:
725131, 725132, 725133, 725141
Abstract:
An application programming interface (API) for managing resources in a Digital Television (DTV) Receiver/Terminal. The API provides a uniform mechanism for gaining/controlling access to resources, managing multiple resources of the same type, and accessing the individual resource's management state and status. The resources may include, for example, a tuner, a modem, a database, a plug-in module, a cable, a software module, a network interface card, or a conditional access module. The resources are monitored and controlled either locally at the terminal, or remotely, e. g. , from a head-end or an uplink. The API provides a resource package () for registering the available resources at the terminal, a resource state management package () for managing states of the resources, and a registry package () for storing objects that represent the resources. Resources of the same type are managed as a group.
