Abstract

A web television includes a monitor, a communication bus, an internet module, a tuner, and a television controller. The internet module is coupled to the communication bus, and is arranged to provide internet video for display on the monitor. The internet video is derived from internet communications between the internet module and internet content providers. The tuner is arranged to select television video for display by the monitor. The television controller is coupled to the communication bus, the television controller is arranged to switch the monitor between the internet video and the television video, the television controller receives character data from a remote control device, and the television controller transmits the received character data over the communication bus to the internet module in a message containing a last received character datum and a current received character datum.
