Basically the UOC is equipped with RGB or YUV input from external, so it is possible to use the DVD input. Selection of these inputs can be done internally within the IC.  But in the G7 and G7A chassis input YUV signal is not used, so in the ground. RGB signal processing flow is described according to the image below : Diagram of the formation RGB signal 1. Signal Yint, uint, and Vint is derived from a series of color decoder and Y / C switch is fed into a series of YUV selector 1. 2. From YUV selector, sub-carrier signal color (U and V) is inserted into the chain matrix. In this matrix series component sub-carrier signal BY of the color (U signal) and BY component of sub-carrier signal color (V signal) in separate. Here the color difference signal in the form of the color sub carrier. GY signal generated by a combination of color difference signals RY and BY. 3. From YUV selector, luminan signal is passed to a series of black stretch. The working principle is to sharpen the series...

This deluxe solar-powered light  uses a battery and solar cells salvaged from a solar lamp with a four-cell battery (4.8 V nominal terminal  voltage). RGB Solar Lamp Circuit Diagram The circuit can operate from any  DC voltage around this value and  its current consumption, at 20 mA,  is low. This means that the battery  can give up to five days of operation. The circuit consists of an Atmel  ATtiny microcontroller which drives  a red, a green and a blue LED directly  from three port pins. Series resistors are of course included to limit  the LED current. The microcontroller  drives the LEDs in sequence to produce an  RGB running light effect. The microcontroller  is also responsible for ensuring that the light automatically switches on when it gets dark  and off when it is light. The light sensor is  made from one of the solar cells from a bro-ken solar lamp (it is more common  for the battery to fail rathe...
