Abstract: A method for locating a device, including: at a first and second router, collecting sets of LAN communication data; based on the sets, determining location types of the routers; at the first router, receiving a wireless transmission from the device; based on the wireless transmission, determining a location of the device; and controlling a set of electronic devices based on the location and the first location type. A method for locating an device, including: at a first router: establishing a wireless connection to the device; receiving a first wireless transmission from the device; and disconnecting from the device; receiving a second wireless transmission from the device at a second router; based on the first and second wireless transmissions, determining connection metrics; based on the connection metrics, determining a location of the device; and controlling a set of electronic devices based on the location.

Abstract: Methods and systems for processing video data are disclosed herein and may comprise receiving within a single mobile multimedia processor chip integrated within a mobile device, a secure key from an off-chip device integrated within the mobile device. The secure key may be decrypted within the single mobile multimedia processor chip, utilizing an on-chip key. The decrypted secure key may be stored within the single mobile multimedia processor chip. The received encrypted data may be decrypted within the single mobile multimedia processor chip, using the stored, decrypted secure key. The on-chip key may be stored within a one-time programmable (OTP) memory in the single mobile multimedia processor chip. The stored on-chip key may be retrieved from the OTP memory for the decrypting. The stored decrypted received secure key may be encrypted utilizing the on-chip key stored within the single mobile multimedia processor chip.

Abstract: Methods and systems for processing video data are disclosed herein and may comprise receiving in a single mobile multimedia processor chip at least one indicator relating to how input multimedia data is processed. A further indicator may be generated within the single mobile multimedia processor chip, based on the at least one indicator, which identifies whether output data generated from the input multimedia data is secure. The at least one indicator may comprise a first indicator, which identifies whether an instruction cache is used to process the current instruction, a second indicator, which identifies whether an interrupt is used to process the current instruction, and a third indicator, which specifies a program counter value associated with the current instruction. A secure bit may be generated within the single mobile multimedia processor chip, based on the received first, second and third indicators, and on other internal state.
