He added that an online service could appeal to "millennial cord cutters," basically young people who do not want to buy a monthly cable or satellite subscription.
DirecTV explored buying online TV service Hulu earlier this year, but now believes a homegrown service is the way to go.
"There's not much out there to buy beyond Netflix and Hulu," White said during a question and answer session with investors.
Latam growth cut
DirecTV said on Thursday it expects compound annual growth of more than 15 percent in earnings per share by 2016, while also flagging slower-than-expected revenue growth in the important Latin American region.
DirecTV said strong subscriber additions would help it reach earnings per share of $8 by 2016, slightly ahead of Wall Street forecasts.
The company's projections exclude results from Venezuela due to the country's huge currency devaluation.

At the same time, the DirecTV acknowledged that Latin America, long seen as a big potential growth area, would remain troubled, depressed by currency weakness in Brazil and Argentina as well as Venezuela, as well as costs related to the soccer World Cup and capacity expansion.
Revenue for the region is now seen at $8 billion to $9 billion, down from a prior forecast of $10 billion.
At the same time DirecTV expects significant improvement in cash flow starting in 2014 and an acceleration in those improvements through 2016.
Earnings per share for 2016 is seen at $7.62, according to the Thomson Reuters I/B/E/S consensus, while fully reported EPS is seen at $7.34.
DirecTV's shares closed 10 cents higher at $67.02. (Click here for the latest quote.)
NFL, DirecTV agree to framework for Sunday Ticket deal
Separately, Directv and The National Football League have agreed on a framework for negotiations to renew the satellite TV operator's contract to offer the popular NFL Sunday Ticket football package the company uses to attract subscribers, according to two sources with knowledge of the talks.
The two sides "are still in material negotiations," but extended their exclusive negotiating period to work through the remaining issues, according to one of the people. The talks might still not result in an agreement.

A contract that renews DirecTV's exclusive deal would give the satellite operator a key marketing advantage over cable operators. Cable companies sought a deal in 2009, but DirecTV ended up renewing its agreement with the NFL for four years.
