A method for outputting multimedia files and broadcast contents of a selected television (TV) channels on the DPF in a picture-in-picture (PIP) output mode is provided. The method includes: starting the PIP output mode when the DPF plays multimedia files under a DPF mode; defining a PIP region on the DPF; receiving broadcasts of a selected TV channel; and outputting the multimedia files and the broadcast contents of the selected TV channel in the PIP output mode. A related DPF is also provided.

A digital photo frame (DPF) includes a power source, a display panel, a light detector, a motion detector, a processing unit, and a power management unit. The light detector is configured to detect the ambient brightness. The motion detection unit is configured to detect whether anyone is around. The processing unit is connected to the light detector and the motion detector. If the motion detector detects someone is around the DPF and the light detector detects the ambient brightness is below a predetermined value, the processing unit controls the power management unit to provide power to the display panel.

A displaying device includes an input unit, a region defining unit, a content allocating unit, an obtaining unit, a display controlling unit and a display unit. The region defining unit defines regions by incorporating one or more unit regions in each of the regions according to users' selections and generates region defining information. The content allocating unit allocates contents for the regions according to the users' selections and generates content allocating information. The obtaining unit obtains the region defining information, the content allocating information, and contents according to the content allocating information, and then transmits the information and contents to the display controlling unit. The display controlling unit splits a display area of the display unit into the regions defined by the region defining unit and displays the contents in the regions correspondingly according to the content allocating information. Related methods are also provided.
摘要:
A method used in a digital photo frame (DPF) with television (TV) tuning function is provided. The method includes: receiving search parameters input by users during a DPF mode of the DPF; searching in a pre-stored TV program schedule to find TV programs matched the search parameters; determining whether any of the TV programs matched the search parameters is on or about to start at the current time; displaying a program list showing information at least on the “currently on” or “about to start” TV programs among the matched TV programs; switching the DPF from the DPF mode to a TV mode if a “currently on” or “about to start” TV program is selected to play; and receiving and playing the selected TV program. A related DPF is provided.
