An example electronic device (100) includes: an audio and video (AV) processor (101), a computer subsystem (102), a control mechanism (104), and a media playing device (103). The AV processor (101) includes an AV input port (111) to receive external AV signals from an external media source. The computer subsystem (102) is to provide internal AV signals to the AV processor (101). The control mechanism (104) is to control the AV processor (101) to select between the external AV signals and the internal AV signals, and enable the AV processor (101) to transmit selected AV signals to the media playing device (103). The media playing device (103) is to play the selected AV signals.
