The disclosed method may include (1) receiving an input datum to be processed using a non-linear function to produce an output datum, (2) comparing the input datum to a plurality of indexes of a lookup table, where the indexes designate input endpoints of a plurality of piecewise-linear sections approximating the non-linear functions, and where the lookup table further includes, for each of the indexes (a) a slope of the piecewise-linear section corresponding to the index, and (b) an axis intercept of the piecewise-linear section corresponding to the index (2) selecting, based on comparing the input datum to the plurality of indexes, an index that designates the piecewise-linear section associated with the input datum, and (4) calculating, using the slope and the axis intercept corresponding to the selected index, the output data corresponding to the input datum. Video processing systems employing such a method are also disclosed.

An apparatus may include a control unit to determine whether a display state notification indicating a dimensional display process exists. The control unit may set an output form of display data to be displayed on image data to an output form corresponding to a display state indicated by the display state notification.

A high definition surveillance video storage optimization system executes purging directives according to policy and retention meta data. Segments of video are purged from storage when thresholds of retention metrics are applied and when policy permits. Retention metrics are determined from acoustic sound energy, radiation energy, access control events, and movement. Policies reflect calendars and elapsed time, percentage of available storage, statutory and judicial mandates, and utility of the stored segments. Extrinsic sensor data and operations are recorded into non-transitory retention meta data stores. Metrics are transformed into retention flags at either time of recordation or time of purgation. Security file storage includes metadata about the environment acquired by sensors include doors, audio noise, object identification and tracking and inputs which influence retention or purging. A circuit filters for motion and stores metadata per segment. Meta data enables content based purging of least consequential files.

The present invention relates to a video signal transmission device and the like that can support a variety of system specifications. The device includes a packer unit, an encoder unit, and a serializer. The packer unit generates, from a video signal of one or more pixels, a plurality of block signals having a packet configuration of size corresponding to the number of pixels and the number of tone bits of a color signal constituting a video signal. At this time, a control signal including a pulse having a width corresponding to the number of pixels and the number of tone bits is also generated. The encoder unit applies encoding processing having encoding efficiencies that are different between a first period and a second period of a control signal that are distinguished depending on existence or non-existence of a pulse to the block signals.
