Embedded System for Controlling Quality Transmission of Television Programs

Abstract

This article presents the functioning and construction principles of a programmable system with a microcontroller for controlling the quality transmission of TV programs. The measuring and controlling process takes place based on a scanning program introduced in the system memory. The information concerning the TV signal level, the video, and the audio signal can be displayed on an LCD screen or stored in the system memory. The proposed system is useful in the TV cable systems and in the terrestrial television for establishing the quality of transmission and reception of the television programs.
