Harmonic said its encoders are used to transmit more than 2,300 SD and HD channels worldwide, which Harmonic claims is almost twice as many IPTV channels as its two top competitors combined.

Harmonic’s tally includes approximately 1,050 channels in Europe (almost 50 percent of all channels in the region), more than 300 in Asia (20 percent market share) and nearly 1,000 in North, Central and South America. The results were published by Multimedia Research Group in its report “IPTV Market Leader Report.”

IPTV providers using Harmonic encoders include Aliant (Canada), CanalSatellite (France), NTT Plala (Japan), SaskTel (Canada), SOFTBANK Yahoo! BB (Japan) and Video Networks (U.K.).
