Patent number: 8800059Abstract: 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.Type: GrantFiled: August 27, 2012Date of Patent: August 5, 2014Assignee: Broadcom CorporationInventor: Jeffrey Douglas Carr

Patent number: 8191166Abstract: Systems and methods that securely handle control information are provided. In one example, a system may include an application specific integrated circuit (ASIC). The ASIC may include, for example, a content processing block and a control processing block. The content processing block may be coupled to the control processing block. The content received by the ASIC may be associated with the control information received by the ASIC. The control processing block may be adapted to validate the control information received by the ASIC. The content processing block may be adapted to process the content received by the ASIC in accordance with the validated control information.Type: GrantFiled: December 4, 2002Date of Patent: May 29, 2012Assignee: Broadcom CorporationInventor: Jeffrey Douglas Carr

Patent number: 7810152Abstract: Systems and methods that may securely control access to device functions are disclosed. A request is received to enable a feature of the device. In one embodiment, the device may be a set top box, for example. The device determines whether the feature is disabled, whether the feature can be enabled with authorization and whether a requester is authorized to enable the feature of the device. If the feature is disabled, if the feature can be enabled with authorization and if the requester is authorized to enable the feature of the device, then the feature of the device is enabled.Type: GrantFiled: May 8, 2002Date of Patent: October 5, 2010Assignee: Broadcom CorporationInventor: Jeffrey Douglas Carr

Patent number: 7797550Abstract: Systems and methods that securely buffer content are provided. In one embodiment, a system may include, for example, a processor and a memory. The memory may be coupled to the processor. Before content leaves the processor for the memory, the processor may secure the content. After the secured content enters the processor from the memory, the processor may recover the content from the secured content.Type: GrantFiled: December 4, 2002Date of Patent: September 14, 2010Assignee: Broadcom CorporationInventor: Jeffrey Douglas Carr

Patent number: 7689760Abstract: 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.Type: GrantFiled: July 20, 2004Date of Patent: March 30, 2010Assignee: Broadcom CorporationInventors: Jeffrey Douglas Carr, Mark Buer

Patent number: 7681043Abstract: Systems and methods that may configure features or functions of a device, such as a set top box, for example, using a chip are provided. The chip may include a processor and a memory array. The memory array may include a non-volatile memory and may be in communications with the processor. The non-volatile memory may include a set of mode control bits, each mode control bit being one-time programmable. The device features may be securely programmed via the set of mode control bits of the non-volatile memory that may be programmed during a programming cycle and may not be modified further after the completion of the programming cycle.Type: GrantFiled: May 8, 2002Date of Patent: March 16, 2010Assignee: Broadcom CorporationInventor: Jeffrey Douglas Carr

Patent number: 7594110Abstract: 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.Type: GrantFiled: April 26, 2006Date of Patent: September 22, 2009Assignee: Broadcom CorporationInventor: Jeffrey Douglas Carr
