International Classification:

H04N 7/12

US Classification:

37524002, 375E07076

Abstract:

A policy enforcement device performs a method for adjusting video compression parameters for encoding source video based on a viewer's environment. The method includes: receiving, from a video receiving device, a video stream identifier indicating a video stream and a source of the video stream, wherein the video receiving device is remote from the source of the video stream; receiving an indication of environmental conditions of a viewer of the video stream using the video receiving device; determining a set of video compression parameters based on the indication of environmental conditions of the viewer; sending the set of video compression parameters to the identified source of the video stream to enable encoding of the video stream to a different compression level.

Abstract:

An improved power supply for one or more electric discharge lamps includes a high frequency oscillator-inverter circuit coupled to the output of a full-wave rectifier circuit via a transformer primary winding (25). The rectifier circuit is energized from a low frequency source of AC voltage. The oscillator-inverter circuit supplies high frequency oscillations to the lamp via a frequency-dependent ballast coupling circuit. A regenerative power supply is coupled to the transformer primary winding by means of a secondary winding (62) of the transformer thereby to charge a capacitor (49) operative as a switchable auxiliary supply voltage for the oscillator-inverter circuit. Improved start-up operation is achieved by winding the transformer (25, 62) so as to provide a polarity inversion for the supply of electric energy to the regenerative power supply.
