Summary of REMOTE DIGITAL VIDEO SELECTOR WITH PIC16F628 CCS C
This article describes a DIY three-way video selector using the PIC16F628 microcontroller to manage component video and fiber-optic digital inputs. The project addresses home theater connectivity issues by allowing users to switch between multiple sources like DVD, Xbox, and PS2 via an infrared remote and LCD status display. It highlights the use of EL4332 for component video switching and 74HC series chips for handling high-speed fiber-optic signals, aiming to solve limitations in existing AV equipment.
Parts used in the Remote Digital Video Selector:
- PIC16F628 Microcontroller
- EL4332 Component Video Switcher
- 74HC Series High-Speed TTL Chips
- Fiber Optic Transceivers
- Infrared Remote Control Circuit
- LCD Status Display Module
- Coaxial Output Components
- Component Video Input/Output Ports
- S-Video and Composite Video Interfaces

PIC16F628 CCS C VIDEO SELECTOR.
Fiber optic transceivers do not have any elected, I in the electronic market is not easy to find a sale.
Infrared remote control circuitry not previously played, nor how tested, for the first circuit, after repeat procedures. LCD SCM and LCD control part for me is nimble.
Now the home, need to connect the equipment to the TV more and more to my family as an example, the need to at least DVD, XBOX, PS2, set-top boxes and video cameras connected to my plasma screen. /S-Video,,VGA, Unfortunately, I only way the plasma composite video / S-Video input, component video input only way, VGA But there are two input Unfortunately, I do not need that much. YAMAHA,AV,: I have a YAMAHA amp, bought relatively early, although the number Road AV input, but it has two drawbacks:
S-Video,S-Video Composite video and S-Video input and output is completely independent, that is, coming from the composite video signal from the composite video output only on out, S-Video is a virtue No multi-component input and output
S-Video,, As my TV tuner only ordinary composite video output, if you want to use of other S-Video equipment, we will have to temporary interpolation line, trouble dead. (S-Video,,,S-Video) (I plasma composite video input and S-Video is the common way, with or without signals, as long as the plug, S-Video always priority)
To address this frustration, I find out about the Internet, I found that in order to meet the requirements of the products do not, and prices are very expensive.Video Selector After preparation, I have decided to produce their own a Video Selector.
