Video data in an encoded frame is reduced by adjusting orthogonal transform coefficients in the encoded frame during trick play operation such as fast forward or fast reverse. The orthogonal transform coefficients are adjusted by selecting essential orthogonal transform coefficients with high energy and non-essential orthogonal transform coefficients with low energy, maintaining or strengthening the essential orthogonal transform coefficients and attenuating or removing the non-essential orthogonal transform coefficients. In an MPEG bit stream, the encoded frame is an I-frame and the orthogonal transform coefficients are discrete cosine transform (DCT) coefficients.

Embodiments of the present invention may be directed to an electronic connector. More specifically, the electronic connector may include a single connector body and a mounting end operable to couple the single connector body with an electronic board of an electronics unit. The electronic connector may also include a lower jack portion disposed in the single connector body and include multiple lower pin receptacles, where the lower jack portion is disposed adjacent to the mounting end and is operable to receive a first connector end of a first cable. The electronic connector may further include an upper jack portion disposed in the single connector body and include multiple upper pin receptacles, where the upper jack portion is disposed above the lower jack portion and is operable to receive a second connector end of a second cable.

A fiber optic voltage conditioner, and method therefor, generally relate to voltage conditioning. In such a fiber optic voltage conditioner, there is a laser, and an optical circulator is coupled to receive a light signal from the laser. A controller is coupled to the laser and is configured to generate first control information for wavelength-drift control of the laser. A data acquisition module is coupled to the controller and is configured to generate second control information for the controller for adjustment of the first control information. A photodetector is coupled to the optical circulator to receive a returned optical signal and is coupled to the data acquisition module to provide an analog output signal thereto. The photodetector is configured to generate the analog output signal responsive to the returned optical signal. The data acquisition module is configured to generate the second control information using the analog output signal.
