Abstract:
1. A device, comprising: two channel selectors, wherein each of the channel selectors is configured to select a channel from multiple channels of television signals and to output the television signal of the selected channel to either or both of two output devices for presentation to a user; picture-in-picture (PIP) display circuitry configured to combine the television signals from the two channel selectors and to output the combined television signal as a PIP display signal to either or both of the two output devices; and control circuitry configured to cause a first of the channel selectors to output a first television signal, to cause a second of the channel selectors to output a second television signal, and to cause the PIP display circuitry to combine and output the first and second television signals as a PIP display signal to a first of the output devices in a first mode of operation; wherein the control circuitry is configured to switch from the first mode to a second mode of operation in response to a command, wherein, in switching to the second mode, the control circuitry is configured to cause the PIP display circuitry to cease outputting of the first and second television signals as a PIP display signal, transfer the first television signal from the first of the channel selectors to the first of the output devices as a non-PIP display signal, and select a third television signal indicated by the command using the second of the channel selectors.
