MSG Networks has tipped off streaming coverage of New York Knicks NBA telecasts.

Authenticated Cablevision subscribers to MSG Network can now watch Knicks games and related fare on computers, tablets and smartphones via the MSG GO platform at no additional cost.

The service, currently only available to verified Optimum customers, tipped off on Dec. 20 with the Knicks-Phoenix Suns game. Cablevision’s Optimum subscribers can watch the RSN action inside and outside of their residences, as well as if they leave the club’s TV territory.

MSGN subscribers with a supported smartphone or tablet can download the free MSG GO app by visiting the App Store or the Google Play store.  On computers, customers may visit MSGGo.com.

A spokesman said RSN executives are in talks with other distributors to expand its MSG GO roster. 

Whereas Time Warner Cable SportsNet and Time Warner Cable Deportes, the RSN homes of  the Los Angeles Lakers, has been offering in-market simulcast since its rookie campaign in 2012-13, the current season has marked a major move by the NBA and its teams to allow for the practice.

MSG Network has joined 17 Fox Sports regionals – a handful tested the process last season -- and six under the Comcast SportsNet banner in offering the TV Everywhere experience around regional NBA games.

Altitude Sports & Entertainment, the RSN home to the Denver Nuggets, also expects to enter this arena in 2015.
