Описание: MPEG-2 vs MPEG-4 FOR STB (SET TOP BOX)

MPEG-2
Older standard (1994), widely used for DVB-T/S/C broadcasts (SD channels, digital TV).
Compression efficiency – Lower (needs more bandwidth for same quality).
Usage in STBs – Older SD channels, legacy broadcasts (some regions still use it).
Devices – Older STBs, DVD players.

MPEG-4 (H.264/AVC)
Newer, efficient standard (2003), widely adopted for HD broadcasts (DVB-T2, satellite, cable).
Compression – 2x better than MPEG-2 → streams use less bandwidth for same quality.
Usage in STBs – HD channels, IPTV, streaming (YouTube, Netflix use H.264 too).
Devices – Modern STBs, smartphones, Blu-ray players, smart TVs.

EXAMPLE
SD channels (e.g., SD1, SD2) → often MPEG-2.
HD channels (e.g., HD1, sports) → MPEG-4.
