Analog TV Tools project

This project focuses on developing a suite of software tools for decoding analog TV signals. The current toolset includes two primary components:

• Command Line Interface (CLI) for anlog TV decoder: This command line tool enables the conversion of digitized analog CVBS SECAM signals into standard AVI video files. For using examples please see the tests at https://github.com/rukhov/analog-tv-tools/tree/main/pytests.
• AnalogTv/TvDecode GNU Radio Block: This component allows integration of the Analog TV decoder into the GNU Radio ecosystem.
