The present disclosure provides an image sensor semiconductor device. When the digital audio data is not output depending on the reception state of the digital audio data, the commercial digital audio data is automatically output. The network-monitoring unit is operable to monitor and analyze network transmission quality for the server and client device, and the image-processing unit is operable to adjust the resolutions of a region-of-interest and a region-of-non-interest in an image based on the network transmission quality, such that the client device can receive the image via the network.
