Embodiments of the invention describe a method for transcoding an input video in a first encoded format to an output video in a second encoded format, wherein the videos include a set of segments and each segment includes frames. First, the method is determining a set of downsample resilient segments in the input video and a set of full-resolution segments in the input video. Next, the method is downsampling the set of downsample resilient segments to produce a set of downsampled segments and transcoding the input video using the set of full-resolution segments and the set of downsampled segments to produce the output video including at least two segments with different resolutions.

A method and apparatus for measuring bandwidth of light emitted from a laser is disclosed which may comprise: a first and second wavelength sensitive optical bandwidth detectors providing, respectively, an output representative of a first parameter indicative of the bandwidth of the emitted light as measured respectively by the first and second bandwidth detectors, and an actual bandwidth calculation apparatus adapted to utilize these two outputs as part of a multivariable linear equation employing predetermined calibration variables specific to either the first or the second bandwidth detector, to calculate a first actual bandwidth parameter or a second actual bandwidth parameter. The first actual bandwidth parameter may be a spectrum full width at some percent of the maximum (“FWXM”), and the second actual bandwidth parameter may be a portion containing some percentage of the energy (“EX”). The first and second bandwidth detectors may an etalon and the outputs may be representative of a fringe width of a fringe of an optical output of the respective etalon at FWXM. The precomputed calibration variables may be derived from respective three dimensional plots representing, respectively, detector outputs in relation to a calibrating input light with known values of the first and second actual bandwidth parameters, which may be FWXM and EX. The first / second three dimensional plot may provide a solution: (first / second output)=(a / d*(calibrating input light known value of FWXM))+(b / e*(calibrating input light known value of EX)+c / f; and the actual bandwidth calculation apparatus may use the derived equation: (first actual bandwidth parameter)=((b*(second output))−(e*(first output))+ce−bf) / (bd−ae), or the equation: (second actual bandwidth parameter)=((a*(second output))−(d*(first output))+cd−af) / (ae−bd). FWXM may be FWHM and EX may be E95. The transfer function of the first optical bandwidth detector may be selected to be much more sensitive to FWXM than to EX and the transfer function of the second optical bandwidth detector may be selected to be much more sensitive to EX than to FWXM.

The invention provides an MEMS absolute pressure sensor and a processing method thereof. The sensor comprises a glass cover plate, a silicon pressure sensing film and a glass substrate. One side of the silicon pressure sensing film is in anodic bonding with the glass substrate to form two communicated vacuum reference cavities, the other side of the silicon pressure sensing film is in anodic bonding with the glass cover plate to form two independent open type gas pressure sensing structures, and the two communicated vacuum reference cavities correspond to the two independent open type gas pressure sensing structures up and down, and form a series mutual inductance double-capacitor structure with a silicon pressure sensing film, and a lead electrode is processed on the silicon pressure sensing film and used for leading out an air pressure detection signal. External air pressure is applied to the silicon pressure sensing film through the open type gas pressure sensing structure, pressure difference is formed between the external air pressure and the vacuum reference cavity to enable the silicon pressure sensing film to deform, then the distance between the silicon pressure sensing film and the capacitance plate of the glass substrate is changed, and the capacitance value is changed to reflect the external air pressure. The processing technology based on the sensor is few in steps, extremely high in qualified rate, good in long-term stability of products and convenient for large-scale batch production.

A FOV(field of view) dependent LOS(line of sight) scan method and apparatus for a turret aided camera system with continuous zoom optics is disclosed. According to this invention, the scan width and rate of the LOS are automatically determined as a function of the FOV selected by the user: scan width=f1(FOV, m) and scan rate=f2(FOV, te) where m is the observation range constant and te is the eye integration time. Moreover, the sensitivity to the FOV can be controlled by adjusting the relevant parameter sets (said m and te), allowing the user to select the scan condition proper to himself. This invention is quite useful for all kinds of turret aided camera system (the IR or day light TV cameras) for reconnoitering application.
