A processing system includes a transport stream aggregator that receives a plurality of transport streams in a transport stream format and that generates an aggregated transport stream in response. The transport stream aggregator processes transport stream packets of the plurality of transport streams and replaces a packet synchronization field with a customized synchronization field. A processing device is configured to generate a processed video signal from the aggregated transport stream.

A processing system includes a memory module that includes a register space for storing a plurality of register data in a plurality of registers and secure access data corresponding to the register space. A register arbitration module operates to receive a request to access one of the registers from a client module; retrieve secure access data corresponding to the client to determine if the client is trusted; and to grant the request to access the register if the client is trusted. If the client is not trusted, the register arbitration module retrieves secure access data to determine if the register is non-secured for the client. The register arbitration module grants the request to access the register when the register is non-secured for the client.

A content access device includes an interface module that receives a transport stream and outputs a processed transport stream. An input buffer buffers the received transport stream. A polling processor processes the transport stream based on the at least one key to generate the processed transport stream, wherein the polling processor operates to descramble individual packets of the transport stream in a plurality of polling slots of a polling loop. An output buffer buffers the processed transport stream for output by the interface module.

A video processing device includes a substrate. A plurality of ring oscillators generate a corresponding plurality of ring oscillator outputs. A control circuit generates power adjustment signals for adjusting at least one power supply voltage of the video processing device, based on the plurality of oscillator outputs.

A device includes a key store memory, a rule set memory, a plurality of cryptographic clients, and a key store arbitration module. The key store memory stores a plurality of cryptographic keys and the rule set memory stores a set of rules for accessing the cryptographic keys. A cryptographic client is operable to issue a request to access a cryptographic key(s) and, when access to the cryptographic key is granted, execute a cryptographic function regarding at least a portion of the cryptographic key to produce a cryptographic result. The key store arbitration module is operable to determine whether the request to access the cryptographic key is valid; when the request is valid, interpret the request to produce an interpreted request; access the rule set memory based on the interpreted request to retrieve a rule of the set of rules; and grant access to the cryptographic key in accordance with the rule.
