BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to an in-wall video/audio signal adapter device and more particularly to an in-wall video/audio signal adapter device including a first adapter and a second adapter. The first and second adapters are mounted in a first cavity and a second cavity previously formed on a wall. CAT5/CAT6 Internet signal transmission cables are previously laid in the wall for connecting the first adapter with the second adapter. Accordingly, the CAT5/CAT6 Internet signal transmission cables are hidden in the wall without being exposed to an indoor environment.
2. Description of the Prior Art
The existent video/audio signal transmission cable applied to video/audio multimedia products has a transmission distance limited to about 10 meters. However, in indoor layouts, a video/audio multimedia output equipment (such as a DVD player) is often spaced from a video/audio multimedia receiving equipment (such as a display) by a distance farther than the effective transmission distance of the video/audio signal transmission cable. In this case, the video/audio multimedia receiving equipment will be unable to receive the video/audio signals output from the video/audio multimedia output equipment.
A video/audio signal adapter has been developed to solve the above problem. The video/audio signal adapter includes a transmitter unit and a receiver unit. The transmitter unit includes a video/audio signal input connector and two RJ45 output connectors. The receiver unit including a video/audio signal output connector and two RJ45 input connectors. The video/audio signal input connector of the transmitter unit is connected to an output equipment (such as a DVD player) via a video/audio signal transmission cable. CAT5/CAT6 Internet signal transmission cables are connected between the RJ45 output connectors of the transmitter unit and the RJ45 input connectors of the receiver unit. The video/audio signal output connector of the receiver unit is connected to a receiving equipment (such as a display) via a video/audio signal transmission cable. Accordingly, the allowable mounting distance between the output equipment and the receiving equipment can be effectively elongated.
However, according to the above arrangement, the CAT5/CAT6 Internet signal transmission cables connected between the transmitter unit and the receiver unit are exposed to an indoor environment. The CAT5/CAT6 Internet signal transmission cables have very long lengths. This leads to poor appearance of the indoor environment. Moreover, people may be tripped by the CAT5/CAT6 Internet signal transmission cables. In addition, the transmitter unit and receiver unit are not fixed on a stationary article. The transmitter unit and receiver unit are often randomly placed on the ground or on a desktop. Under such circumstance, the transmitter unit and receiver unit will occupy much room. Also, the transmitter unit and receiver unit are likely to displace due to external force. As a result, the signal transmission cables connected with the transmitter unit and receiver unit by way of plugging are apt to unplug and detach from the transmitter unit and receiver unit.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an in-wall video/audio signal adapter device. The in-wall video/audio signal adapter device includes a first adapter and a second adapter. The first adapter includes a transmitter unit including a video/audio signal input connector, an equalizer, two RJ45 output connectors and a power input terminal. The transmitter unit is fixed on a mount. The mount can be locked in a first cavity previously formed on a wall. The second adapter includes a receiver unit including a video/audio signal output connector, an equalizer and two RJ45 input connectors. The receiver unit is fixed on a mount. The mount can be locked in a second cavity previously formed on the wall. CAT5/CAT6 Internet signal transmission cables are previously laid in the wall. The first adapter is connected to an output equipment via the video/audio signal input connector. The CAT5/CAT6 Internet signal transmission cables are connected between the RJ45 output connectors of the first adapter and the RJ45 input connectors of the second adapter. The second adapter is connected to a receiving equipment via the video/audio signal output connector. Accordingly, the allowable mounting distance between the output equipment and the receiving equipment can be effectively elongated. The CAT5/CAT6 Internet signal transmission cables connected between the first and second adapters are hidden in the wall without being exposed to an indoor environment.
The present invention can be best understood through the following description and accompanying drawings wherein:
