Abstract: A wireless transmission method for electronic apparatuses to transmit audio and visual signals to a television and device thereof include steps as follows. First, audio and visual signals that electronic apparatuses desire to play are modulated. Then the modulated audio and visual signals are transformed to television carrier signals via a low-power television signals wireless transmitter. The television carrier signals are sent to a television by setting the electronic apparatuses near the television. With a very short distance between the electronic apparatuses and the television, the transmitted carrier signals can go through the television to a tuner inside the television, then the tuner can direct receive the television carrier signals. In this way, the transmission method of the present invention does not need signal transmission lines between the electronic apparatuses and the television.

Abstract: A digital photo frame having auto-adjusting capability to match a picture and a display panel includes a frame body, an input and output interface, a control unit, an image processing unit, and a display panel and a control panel. The control unit determines whether a picture matches with the display panel according to a digital image format of the picture. If the picture matches with the display panel, the picture is direct displayed on the display panel. If the picture mismatches with the display panel, the control unit rotates the picture and then to display the picture on the display panel. Therefore, the picture can be auto-adjusted to match with the display panel.
