The first question we would like to answer is: what do we mean nowadays for video processing In the past, more or less till the end of the 80`s there where two distinct worlds: an analog TV world and a digital computer world. All TV processing from the camera to the receiver was based on analog processing, analog modulation and analog recording.

With the progress of digital technology, a part of the analog processing could be implemented by digital circuits with consistent advantages in terms of reproducibility of the circuits leading to cost and stability advantages, and noise sensitivity leading to quality advantages. At the end of the 80`s completely new video processing possibilities became feasible by digital circuits. Today, image compression and decompression is the dominant digital video processing in term of importance and complexity of the all TV chain. In the near future digital processing will be used to pass from standard resolution TV to HDTV for which compression and decompression is a must, considering the bandwidth that it would require for transmission. Other applications will be found at the level of the camera to increase the image quality by increasing the number of bit from 8 to 10 or 12 for each pixel, or by using appropriate processing aiming at compensating the sensors limitations (image enhancement by non-linear filtering and processing). Digital processing will also enter into the studio for digital recording, editing and 50/60 Hz standard conversions. Today the high communications bandwidth required by uncompressed digital video necessary for editing and recording operations, between the studio devices limits the use of full digital video and digital video processing at studio level. Why video compression has become the dominant video...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
