Appl. No.:

10/791934

Inventors:

Ronald P. Cocchi - Seal Beach CA, US
Christopher P. Curren - Brentwood CA, US
Kevin T. Collier - Gardena CA, US

Assignee:

The DIRECTV Group, Inc. - El Segundo CA

International Classification:

G06F 21/02

US Classification:

726 26, 726 27, 726 29, 713194, 380200, 380210, 380231

Abstract:

A system and method of controlling access to a media program via a receiver communicably coupleable to a conditional access module is described. The apparatus comprises a first processor, a second processor, and an interface module, communicatively coupled to the first processor and the second processor, the interface module for processing all communications with the conditional access module and externally manifesting a single virtual processor to the receiver.

International Classification:

G06F 12/14

US Classification:

711164, 713189

Abstract:

A system and method of verifying a content of a non-volatile reprogrammable memory communicatively coupled to a microprocessor is disclosed. The method comprises the steps of reading at least some of the data stored in the non-volatile reprogrammable memory, computing a value related to contents of the non-volatile reprogrammable memory, and comparing the value with a stored integrity value. The apparatus comprises a microprocessor, a non-volatile reprogrammable memory communicatively coupled to the microprocessor via a first communication path, the non-volatile memory for storing microprocessor program instructions, and a logical module, communicatively coupled to the non-volatile memory via a communication path independent from the first communication path, the logical module for verifying the data stored in the non-volatile reprogrammable memory by comparison of the contents of the non-volatile reprogrammable memory with a stored integrity value.

International Classification:

US Classification:

Abstract:

A digital FM stereo decoder uses the phase characteristics of linear phase FIR filters, together with a trignometric operation, to generate a 38 kHz subcarrier signal from a 19 kHz pilot. The subcarrier signal is mixed with the input composite signal from which the pilot has been removed to shift its L-R component to baseband; the linear phase FIR filters also maintain phase coherence between the subcarrier and the composite signals. A low distortion output is obtained without the use of a phase locked loop for the regeneration of the subcarrier signal.
