Worked on enhancing the iptv-org/iptv repository by delivering HD streaming options within M3U playlists, specifically updating az.m3u to include high-definition entries for İctimai TV, CBC Sport, and Azstar TV. Focused on improving playlist management and streaming media quality, the approach involved precise updates to M3U files to ensure accurate metadata and consistent user experience. Leveraged skills in M3U playlist structuring and Git-based collaboration to align with project standards, emphasizing maintainability and reliability. No critical bugs were reported during this period, as efforts centered on feature delivery and reducing manual maintenance for improved usability across the streaming platform.
