Abstract: A pair of cameras having an overlapping field of view is aligned based on images captured by image sensors of the pair of cameras. A pixel shift is identified between the images. Based on the identified pixel shift, a calibration is applied to one or both of the pair of cameras. To determine the pixel shift, the camera applies correlation methods including edge matching. Calibrating the pair of cameras may include adjusting a read window on an image sensor. The pixel shift can also be used to determine a time lag, which can be used to synchronize subsequent image captures.

Abstract: Embodiments described herein enable a switching device to automatically select AV port(s) coupled to electronic device(s) that a user would like to use to watch and/or listen to content. The AV port(s) may be automatically selected based on receiving a command, determining that a particular remote control device is being used, and/or determining that a particular piece of content has been selected. Upon detection of such events, a source device for providing content is identified from among a plurality of source devices. Thereafter, an AV port from among a plurality of AV ports to which the identified source device is connected is identified. The identified AV port is then selected so that the identified source device becomes connected to an AV port to which a sink device is connected. In this way, the switching device can provide content from the identified source device to the sink device for presentation thereby.

Abstract: There are provided a television set and a desktop display apparatus. The television set comprises a major structure configured to realize a display function, and further comprises: a power supply conversion means configured to convert AC mains into a DC voltage; a power supply allocation means disposed in the major structure and configured to convert the DC voltage output from the power supply conversion means into a DC operating voltage required by respective circuits in the major structure, wherein the power supply allocation means and the power supply conversion means are connected mutually and disposed separately. Since the major structure configured to realize the display function and the power supply conversion means configured to convert the AC mains into the DC voltage are disposed separately, electrical isolation of the DC voltage from the AC mains is realized, so that danger of electric shock of human body is avoided.
Abstract: Laser 3D imaging techniques include splitting a laser temporally-modulated waveform of bandwidth B and duration D from a laser source into a reference beam and a target beam and directing the target beam onto a target. First data is collected, which indicates amplitude and phase of light relative to the reference beam received at each of a plurality of different times during a duration D at each optical detector of an array of one or more optical detectors perpendicular to the target beam. Steps are repeated for multiple sampling conditions, and the first data for the multiple sampling conditions are synthesized to form one or more synthesized sets. A 3D Fourier transform of each synthesized set forms a digital model of the target for each synthesized set with a down-range resolution based on the bandwidth B.

Abstract: Novel tools and techniques are provided for implementing video qualification, which might include implementing video quality measurements at a subscriber premises and qualification of the subscriber premises for particular levels of video data transmission. In some cases, one or more customer premises equipment might comprise video quality chips that might perform measurements of the telecommunications links, and might send the results to a server associated with the service provider. The server might determine available video services, based on the results of the measurements, and might send the subscriber notifications indicating that the subscribers qualify for particular video services. In some cases, implementing video qualification might include the server determining that video service levels provided to a customer premises has been decreased or otherwise negatively affected.

Abstract: Embodiments of the present disclosures provide a method, system and apparatus for transmitting intelligent information. When one frame of video data x is to be transmitted, a SDI sending terminal determines whether there is intelligent information satisfying a transmission condition; the transmission condition comprising that intelligent information is not transmitted and transmission of a frame of video data corresponding to the intelligent information is finished. If there is the intelligent information satisfying the transmission condition, the SDI sending terminal adds intelligent information y being one item of the intelligent information satisfying the transmission condition into a preset position of the video data x; and transmits the video data x having the intelligent information y. By using the solutions of the present disclosures, implementation costs are reduced and security is improved.
