Output systems (e.g., television controllers, audio output devices, display devices) for accessing digital content from a service provided by one or more servers over the Internet are herein disclosed and enabled. To receive and play the digital content, the output system may obtain authentication information for accessing the service, receive a list of digital content that are available from the service for selection at the output system, receive output data from the service related to the selected digital content, and then play either audio data or video data, which is related to the received output data, at an output device coupled to the output system. The output system may further implement a discovery operation for a client device (e.g., smart phone or information pad), which is in the same network as the output system, to wirelessly discover the output system for providing output service to the client device.
