Buyers should prioritize servers that support H.265 (HEVC) compression, which ensures high-quality video streaming even at lower bandwidths. Ensure the server offers 4K and Full HD (1080p) resolution stability with a 99.9% uptime guarantee. Key features should include an Electronic Program Guide (EPG), Video on Demand (VOD) libraries with localized Arabic content, and Time-shift/Catch-up functions. Compatibility with multiple protocols like M3U, Xtream Codes API, and MAG portals is essential for hardware versatility.
