Abstract: A broadcasting system for AV program selection comprising a network, an AV signal providing system, a user device and a digital AV signal processing device is proposed. The network, the AV signal providing system, the user device and the digital AV signal processing device are in communication with each other via the network. A broadcasting method is applied to the AV signal providing system. The broadcasting method comprises steps of: providing a plurality of AV programs for selection; and transmitting an AV signal corresponding to a selected one of the plurality of AV programs to the digital AV signal processing device in response to a user's selecting operation on an AV program menu revealed by way of the digital AV signal processing device, wherein the AV program menu contains information of only partial the plurality of AV programs, and is created by way of the user device.

Abstract: A setting and modifying method of a user operating interface is used between a user device and a digital audio/video signal receiving and processing device through a network. The setting and modifying method includes the following steps. Firstly, the user device acquires a first user operating interface setting information from the digital audio/video signal receiving and processing device. Then, the contents of the first user operating interface setting information are modified to generate a second user operating interface setting information. Afterwards, the second user operating interface setting information is transmitted from the user device to the digital audio/video signal receiving and processing device through the network for setting the user operating interface.
