Abstract: A method and system for a digital home network trace and debug tool is described. The system includes a network filter driver to capture packets from a network, a network sniffer manager to manage the network filter driver, a state engine to manage states of the received packets, a packet parser to determine a transport protocol type and a format type for a received packet, one or more packet type parsers to parse the received packets according to the determined format type, and a GUI to display information associated with the received packets. The method includes receiving a packet at a network device, determining whether a source IP address matches a device IP address in a GUI, determining whether a destination IP address matches a device IP address in the GUI, and determining a transport protocol type, and parsing the packet according to the determined transport protocol type. Network packets may be linked or split up as necessary to make logical protocol specific commands.

Abstract: A processor-based system may be controlled using a digital camera. The digital camera can provide luminance and motion information which may be analyzed to determine whether to alter one or more of the power consumption state, the operation of system utilities, or the operation of a screen saver.
