HBO's Go service streams HBO movies, specials, and series to "authenticated" HBO subscribers

Time Warner Cable began testing its HBO and Cinemax Go “TV Everywhere” online video services Wednesday, starting with a private beta test for their super-premium Signature Home customers who pay $199+ for cable, broadband, and phone service.

Signature Home customers signed up for HBO and/or Cinemax will receive e-mail from the company that includes login instructions for the authenticated video service, which will be included in the cost for both premium channels.  Customers must subscribe to one or both premium channels for access.  Time Warner Cable’s Jeff Simmermon says other Time Warner Cable premium channel subscribers will get access as soon as next week.

For now, Time Warner’s implementation of the online video services will support Mac and PC computers.  Tablet and smartphone owners will have to wait for respective apps coming at a later date.

The cable company’s gradual rollout of the streaming video service is designed to prevent subscribers from overloading the company’s servers, which happened with the introduction of its iPad online viewing app.

“Rather than spend time aggregating a large list of volunteers across our footprint, vetting them against various eligibility requirements, and making sure that each of our markets is equally represented to arrive at a final approved master list, we’re going with all SignatureHome customers,” Simmermon said. “This will allow us to take a representative sampling from across all markets — which have varied tech infrastructures — without overloading our systems.”

Time Warner is one of the last major cable operators to unveil the premium movie channel streaming service.

More than 1,400 movies, specials and series are available for streaming from HBO Go.  Cinemax’s counterpart is more limited — just over 400 movies and soft core adult entertainment from its Max After Dark series.
