System and method for preserving external storage device control while in picture-outside-picture (POP) or picture-in-picture (PIP) modes
View Patent ↗A system and method permits time-shifting or recording for any tuner input, regardless of whether the tuner input is being used for POP (or PIP) or main viewing window. This allows POP (or PIP) video modes and recording to an external recording device to be carried out simultaneously. In one example system and method, a switch is controlled in accordance with a control program of the television to dynamically select which inputs are routed to the main and sub viewing windows.
1. A television connectable to an external storage device, the television comprising:
a video processor including an analog input to an analog processing operation thereof and a digital input to a digital processing operation thereof;
an MPEG encoder including an output connected to the digital input of the video processor;
a switch supplied with a plurality of analog input signals;
an interface supplied with an output of the MPEG encoder and connected, in use, to an external recording device;
a control section for controlling the switch to selectively supply one or more of the analog input signals to the MPEG encoder and the analog input of the video processor.
2. The television according to claim 1 , wherein the control section controls the switch in a full-screen viewing mode to supply a first analog input signal to the analog input of the video processor for full-screen display and to the MPEG encoder for output to the external recording device via the interface and in a picture-in-picture or a picture-outside-picture mode to supply the first analog input signal to the MPEG encoder for main window display and for output to the external recording device via the interface and a second analog input to the analog input of the video processor for sub-window display.
3. The television according to claim 1 , wherein the video processor further includes:
one or more additional digital inputs; and
a switch for selecting a digital input signal supplied to the digital input or to the one or more additional digital inputs.
