Cablevision Systems has launched an Optimum App for iPhone and iPod touch to deliver the full cable video lineup to those devices in the home, extending the functionality of the iPad app that debuted in April. Cablevision customers can now receive more than 300 channels of live TV and thousands of titles of VOD on all three devices, in addition to DVR management, interactive guide information and search. For the first time, customers can use the app on all three devices as a virtual remote control for conventional TVs in the home.The Optimum App is available free in the Apple App Store. Customers who have already downloaded a previous version of the Optimum App for iPhone and iPod touch, which did not include access to live TV, VOD content or remote control functionality, can update to the new and full-featured version. Since its launch in April, the Optimum App for iPad had been downloaded more than 200,000 times.
