PBS has released an update to its iPad app adding support for AirPlay video streaming on iOS 4.3 devices. Originally released last fall, the PBS app allows users to view current programs and content from the PBS archives streamed to their iPad on-demand, with access to classic PBS shows and new content created specifically for the iPad. Version 1.2 adds the ability to stream video to an Apple TV using AirPlay and now supports multitasking allowing users to quickly resume where they left off in a program after switching between apps. The update also fixes issues with audio playback when using the Mute switch on the iPad and adds several performance enhancements and network-related improvements. PBS for iPad is available from the U.S. App Store as a free download.
