The OTT service is defined as services provided via Internet, and video service is one of the most popular OTT services. To avoid being exploiting network resources and try to share the OTT service revenue, telecom operators or telcos, with the advantages of running CDN and IDC services, may choose to jump into OTT market by launching telco-OTT services.
Chunghwa Telecom, being the largest telcos in Taiwan with experience of running MOD, the IPTV service, also launched its OTT service, CHT Video, to share the OTT revenue. Based on the broadcasting of Rio Olympic Games, CHT Video showed that young generation aged from 18 to 34 years old are the major customers to consume video OTT service, and sport events are one of the most popular attractions that differentiate OTT service from traditional TV offerings. This research conclude that content is still the key to develop OTT service, and Chunghwa Telecom is of advantage to running the telco-OTT service by strentghing content and service model to re-define media on the Internet.
