Analog TV Tools project

This project focuses on developing a suite of software tools for realtime 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 usual AVI video files. For usage examples please see the tests at https://github.com/rukhov/atv-tools/tree/main/pytests.
• ATV/TvDecoder GNU Radio Block: This component allows integration of the Analog TV decoder into the GNU Radio ecosystem.
