About HD Remote Control on an iOS Device
Remote Control from a Phone or Tablet
High-definition (HD) quality provides a premium remote control experience. With HD remote control you can seamlessly watch videos and stream music from a Windows or Mac computer to your iOS device.
HD quality requires higher network bandwidth and computer performance than other options. In general, most recently purchased computers can provide the required performance. Network bandwidth depends on your service provider.
