Technologies are disclosed for enabling users to comprehensively determine their exposures to media and to receive services based thereon. For example, an application can be executed on a computing device associated with a user. The application can continuously monitor audio data that the computing device is exposed to and can generate digital signatures thereof. The digital signatures can be transmitted to a server that comprises a database of reference digital signatures and circuitry configured to compare and match the received digital signatures and the reference digital signatures. When a match is found, the server retrieves information associated with the matched reference digital signature and returns, to the device, the retrieved information. The server can also concatenate matches associated with data received from a plurality of computing devices and provide the concatenated data to a third party, who in turn, returns services to the users based on the received data.

An information processing apparatus causes an encryption key data generating section to generate key data stored in a semiconductor memory by using encryption key source data read from the semiconductor memory and cipher generation data stored therein, and stores the key data in a temporary storage section. The information processing apparatus transmits data encrypted by an encryption circuit by using the key data. Upon receipt of the encrypted data, the semiconductor memory executes a command decrypted by a decryption circuit similarly using the key data. This achieves data communication only between the predetermined semiconductor memory and the information processing apparatus.

A simplified initial image data is generated by thinning out an initial image data, which is obtained by shooting, at a predetermined rate. Image correction is performed to the simplified initial image data by using predetermined development parameters, and the simplified initial image data is converted into a simplified display image which is displayable in a monitor. An operator changes the development parameters while observing the simplified display image. Every time the development parameters are changed, the image correction with using changed development parameters is performed to the simplified initial image data, and the simplified display image is updated and displayed. The initial image data is subjected to the image correction with determined development parameters, and output after being converted into display image data.

Methods and apparatus of channel feedback are disclosed. In OFDM systems, the channel is acquired in the frequency domain. A generic multipath model for wireless channels, however, reveals that the time-domain parameters of the channel require much smaller data than the frequency-domain representation of the channel. Means to extracting the time-domain parameters from the frequency-domain channel samples are described for both the continuous time domain and the discrete time domain. Refinements of the time-domain parameters via minimizing a frequency-domain matching error are also described, which further improve the quality of the channel feedback and reduce the feedback overhead. Channel feedback with the time-domain parameters requires only a small fraction of the feedback overhead that is needed by existing channel feedback schemes, and maintains consistently superior performances over wireless channels of various delay spreads, short or long.
