Digital broadcasting transmitter-receiver for portable computer

Abstract

A digital broadcasting transceiver for a portable computer is provided to view digital broadcasting programs using the portable computer and transmit / receive broadcasting signals by using antennas with high transmitting / receiving sensitivity. A digital broadcasting transceiver of a portable computer includes a case(30), a main board(34), a first antenna(50), and a second antenna(50'). The case has a shape fitted in a bay formed at one side of the main body of the portable computer. The main board is set inside the case and includes a chip for receiving digital broadcasting signals mounted thereon. The first antenna includes an antenna body and transmits / receives broadcasting signals. At least a part of the antenna body is placed inside the case and the first antenna is extended to the outside according to a user's operation. The second antenna is located inside the case and transmits / receives the broadcasting signals. The first and second antennas have high signal transmitting / receiving sensitivity.

Description

technical field [0001] The present invention relates to a notebook computer, in particular to a digital relay receiving and sending device for a notebook computer capable of receiving digital broadcasts by using the notebook computer. Background technique [0002] The so-called digital rebroadcasting does not refer to analog signal forms such as sound, but rebroadcasting services provided by compressing digital signal forms. Existing analog broadcasts can only load one image in one radio wave. Sound also needs to be transmitted using other waves. In contrast, digital broadcasting can not only transmit multiple images or sounds in one radio wave, but also compress information without reducing the quality. At the same time, it is more convenient to use a computer to adjust the information, and it can also transmit the information content ordered by the audience, and the two-way communication is stronger. [0003] While this kind of digital relay service is being visualized,...

Problems solved by technology

[0005] However, notebook computers are required to be made smaller, lighter, and thinner in order to improve portability. Therefore, it is very difficult to design the interior of the components for receiving and transmitting digital broadcasts.

[0006] At the same time, on the motherboard of the notebook computer, in order to build a chip for receiving and transmitting digital broadcasts, etc., the motherboard must be redesigned, so it will bring about problems such as increased manufacturing costs of the notebook computer.
