During March 2026, work focused on enhancing the iptv-org/iptv repository by introducing Cubavision HD streaming with an SD fallback, expanding viewing options for users. The approach involved adding the official HD stream to the cu.m3u playlist, sourced from tv.picta.cu servers, while retaining the existing SD link to ensure backward compatibility and minimize disruption. This update demonstrated skills in media management and streaming, with careful M3U playlist handling and server-based content integration. The changes were delivered through clear, traceable commits, laying the groundwork for broader HD adoption while maintaining reliability for users who rely on standard-definition streams.
