Description

Audio / video system and its control method {A AV system and A control method of the AV system}

The present invention relates to an AV system and a method of controlling the same. More particularly, by outputting video information received from a mobile communication device to a display panel of an AV system, it is possible to enjoy a video on a larger screen, The present invention relates to an AV system capable of outputting sound input from a mobile communication device through a speaker of an AV system and a control method thereof.

In general, a mobile communication device is a device that enables communication using airwaves transmitted through a repeater of a base station regardless of a place such as indoors, outdoors, or in a car, and examples thereof include a mobile phone, a PCS, and a PDA.

These mobile communication devices appeared in Korea with the introduction of mobile phones in the mid-1980s, and were initially used only for making and receiving calls. However, with the development of mobile communication technology, mobile communication devices have not only functions as simple phones but also have various functions such as remote PC control, location tracking, transportation fee payment, and electronic commerce using wireless internet.

The evolution of mobile communication can be categorized into generations of analog, first generation, second generation of PCS and cellular service CDMA, and third generation, meaning IMT-2000.

In the first generation, a mobile communication service was provided by an Advanced Mobile Phone Systems (AMPS) method. The AMPS peaked at 2,658 in 1984 and 2.9 million in 1996. However, in January 2000, AMPS was discontinued due to the limitation of frequency utilization and the inability to support various additional services.

In the second generation, CDMA services began in 1996, after which a second mobile telecommunications provider was created, followed by three PCS operators in October 1997, and the expansion of CDMA services began in earnest.

In the second generation, the world's first commercialized CDMA2000 1X, a signal bullet for IMT-2000 service, became the world's first in the world in October 2000. You can get high-speed data service. In this generation, mobile communication devices can transmit not only voice but also video and color images.

The synchronous and asynchronous IMT2000 service for the third generation is a global multimedia mobile communication service with a wired / wireless integrated concept that can transmit and receive voice, data, and video at high speed in a wired / wireless environment with a single terminal. IMT2000 enables global roaming using global standardization and the same frequency, and breaks the voice-oriented service, enabling high-speed, high-quality voice, internet, and video multimedia at 384 Kbps.

With the development of mobile communication services, the functions of mobile communication devices, which were limited to making and receiving phone calls in the early days, are not only games, but also computer control, location tracking, transportation fee payment, Credit card services, mobile security, e-commerce, traffic information, fax functions, sending mail with attachments, finding employment information, lottery services, and watching videos were expanded.

As the functions of the mobile communication devices expanded, the mobile communication devices also developed. Especially in the case of the LCD window of a mobile phone, in the early days, only a phone number was displayed as a black and white two-line LCD, and now it is 65000 colors and 13 line LCD, and the LCD which supports high-definition color of TFT shows up to watch a video and TV. This became possible.

However, while the LCD quality of the mobile communication device is improved, the weight of the mobile communication device is lighter and the size of the mobile communication device becomes smaller due to the convenience of carrying and moving, which is another feature of the mobile communication device. There is a problem that inevitably lead to inconvenience in watching video or watching TV, or playing games.

In addition, since the speaker that is inappropriate to implement a good quality sound is embedded in the mobile phone itself, there is a problem in that it is difficult to enjoy watching a video object, watching TV, or playing games with sound.

On the other hand, as a technology for solving such a problem, Korean Patent Application No. 10-2001-0017324 (name of the invention: cellular phone having an extended display panel, hereinafter referred to as the first cited technology), Korean Patent Application No. 10-2003 -0004116 (name of the invention: a mobile phone auxiliary device using Bluetooth, hereinafter referred to as a second cited technology) has been developed.

However, in the first cited technology, since the extended display panel itself is provided in the cellular phone itself, the size of the extended display panel is inevitably limited in consideration of the portability of the cellular phone, and the weight and size of the cellular phone itself. Increasing the back and the like only adds to the inconvenience of carrying, and therefore, there is a difficulty in actual commercialization.

In addition, the second cited technology is characterized in that it comprises a separate portable cell phone auxiliary device that can receive and output video and audio wirelessly from the mobile phone, but the mobile phone auxiliary device provided separately, considering the portability, Since the size of the display panel is inevitably limited, and there is an inconvenience of carrying another portable device separately from the mobile phone, there is also a difficulty in actual commercialization.

To solve this problem, when using a mobile communication device indoors or in a car, an AV device installed indoors or in a vehicle and having a display panel and a speaker, for example, a TV, a computer, a video, a DVD, an audio, etc. Using the same indoor AV system, audio system installed in a vehicle, GPS system such as GPS, TV, etc., the video displayed on the LCD of the mobile communication device is displayed, and a method for outputting sound to the outside can be found. There is a need.
