Filed:

May 8, 2002

Appl. No.:

10/141599

Inventors:

Jeffrey Douglas Carr - San Diego CA
Mark Buer - Gilbert AZ

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G06F 1200

US Classification:

711103, 711152, 711163, 36518533, 710 14

Abstract:

Systems and methods that may program a non-volatile memory for use in configuring features of a device, such as a set top box, for example, are disclosed. One method may include the steps of beginning a programming cycle; programming mode control bits of the non-volatile memory that correspond to configurations of features of the device; if an interruption occurs during the programming cycle, then rendering the non-volatile memory invalid; and if no interruption occurs during the programming cycle, then rendering the non-volatile memory operational.

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L005/14
H04J003/16

US Classification:

370276, 370282, 370467, 370480

Abstract:

Home phone line network devices, conforming to different versions of the standards, are interconnected and interoperable on a UTP transmission medium. Higher order devices support an overlaid dual logical network structure which allows two pairs of higher order devices to communicate simultaneously using two separate frequency bands. A higher order node contains a high speed PHY, a low speed PHY, and either a high and low order MAC or an enhanced MAC capable of supporting dual frequency band transmission, thereby enhancing total system throughput to the sum of the throughputs of each logical network.

International Classification:

G06F 1/26

US Classification:

713153, 713160, 713161, 713165, 713168

Abstract:

Systems and methods that protect transport stream content are disclosed. The system may include a first module and a second module, the first module having a common interface. The second module is coupled to the first module via the common interface. In one embodiment, the first module is a set top box, and the second module is a conditional access card. In one example, the first module demodulates an incoming transport stream, copy protection encrypts the demodulated transport stream and passes the copy protection encrypted transport stream to the second module via the common interface. The second module copy protection decrypts the transport stream received from the first module, conditional access decrypts at least some of packets of the transport stream that were conditional access encrypted, copy protection encrypts the transport stream and passes the copy protection encrypted transport stream to the first module via the common interface.

International Classification:

H04K 1/00

US Classification:

713151, 713160, 713192, 380 37, 380255

Abstract:

A method and system for processing packets allows consolidation of security processing. Security processing is performed in accordance with multiple security policies. This processing is done in a single front end processing block. Different security processes can be performed in parallel. Processing overhead is reduced by eliminating the need to redundantly check packet characteristics to assess the different security requirements imposed by security policies. Further, the present invention also substantially reduces the CPU cycles required to transport data back and forth from memory to a cryptographic coprocessor.

International Classification:

H04L 9/00

US Classification:

713189, 713165, 713167

Abstract:

Systems and methods that process and protect content are provided. In one example, a system may include, for example, a first device coupled to a second device. The first device may include, for example, an integrated circuit that may include a content processing system and a security system. The security system may include, for example, a digital rights manager. The first device and the second device may be part of a network. The network receives content and control information via the first device. The content processing system processes incoming content based upon at least the control information. The integrated circuit protects the content before placing the content on the network.
