Various embodiments of a video conference system and method are disclosed.

Video conference system and method

Systems, methods, and devices for transmitting video streams are described herein. One method of transmitting video streams includes coordinating transmission of intra-frames in a first video stream with transmission of intra-frames in a second video stream. The method further includes transmitting I-frames in the first and second video streams such that the I-frames do not overlap in the first and second video streams.

Methods of using control data to control a display of an image by a display device include encoding the control data as a line of video data, including the line of encoded control data in a video signal having a number of lines of image video data, transmitting the video signal to the display device, and using the control data to process the video signal and display the image.

Methods and systems for using control data to control a display of an image by a display device

A modulator is controlled in accordance with each sub-frame of a frame of image data. An aiming mechanism is physically adjusted to differently aim each sub-frame. Acoustical noise in physically adjusting the aiming mechanism is reduced.

A burner for combusting particulate fuels comprises a combustion chamber fitted with a plurality of grates stacked in stairstep fashion, each having a downwardly sloping surface over which the fuel flows continuously as it burns. The grates may be horizontally adjustable to change the downward slope of the flowing fuel. Each grate rests upon supports projecting from opposite side walls of the burner. The supports extend beyond the downwardly sloping surfaces of the grates and beyond the forward edge of the fuel bed so that the flow of fuel is diverted by the supports away from the side walls of the firebox, creating air passages which allow air to flow directly to the flame. The burner is fitted with a hopper for receiving and containing the fuel with a baffle plate depending from it shaped to distribute the fuel across the width of the grate in a manner which promotes the flow of the fuel. Tubular channels are positioned below the lowermost grate so that air is supplied to any unburned fuel accumulating at the bottom of the incinerator.
