TBS HD will become the 41st high-definition programming service available to Cablevision's iO TV customers at no additional cost.
"This is great news for local baseball fans, and for our growing base of more than 800,000 HD customers," said John Trierweiler, Cablevision's senior vice president of product management.
Last year, Turner Broadcasting System won the exclusive rights to the divisional play-offs. TBS has also reached a seven-year agreement with Major League Baseball to broadcast the National League Championship Series and American League Championship Series in alternating years from 2007 to 2013.
Cablevision serves three million cable households in the New York Metropolitan area.
