Claim:
A video conference system, built in an internet protocol (IP) network, comprising: a multimedia capturing unit configured to capture video and output a first video signal; a digital enhanced cordless telecommunications (DECT) telephone configured to receive sounds and output a first audio signal; and a video conference terminal apparatus, comprising: an audio processing unit configured to encode the first audio signal to a first audio stream; a video processing unit configured to encode the first video signal to a first video stream; and a network processing unit configured to convert the first audio stream and the first video stream to a first network packet, and transmit the first network packet to the IP network, wherein when the network processing unit receives a second network packet from a phone number of the IP network, the audio processing unit and the video processing unit generates a second audio signal and a second video signal according to the second network packet, respectively, wherein the audio processing unit plays the second audio signal on the DECT telephone and the video processing unit displays the second video signal on a display apparatus; an image processing unit configured to receive the second video signal, and convert the second video signal to a first image; and a first phonebook database configured to store the phone number and a phonebook image corresponding to the phone number, wherein the DECT telephone is further configured to control the image processing unit to select a target area in the first image corresponding to the second video signal, control the video processing unit to display the target area in the second video signal, and control the image processing unit to capture a first target image of the target area from the first image and update the phonebook image corresponding to the phone number in the first phonebook database.
