200937949 九、發明說明： 【發明所屬之技術領域】 本發明是有關於一種多媒體系統，且特別是有關於一 種多媒體系統、信號轉換裝置及將影音控制信號轉換成電 腦控制訊號以控制一電腦之方法。 【先前技術】 近年來高解析多媒體影音介面（High Definition © Multimedia Interface，HDMI)已快速成為全球消費性電子 裝置的數位介面標準，且日常生活中更處處可見HDMI裝 置的縱跡。通常HDMI規範中所稱的來源端（Source)例如 為數位多功能光碟播放機、機上盒或擴大機，而接收端 (Sink)例如為投影機或電視。 HDMI包括最小化傳輸差動信號（Transition Minimized Differential Signaling, TMDS)通道、顯示資料 通道（Display Data Channel, DDC)、消費型電子控制 ❹（Consumer Electronics Control, CEC)通道。TMDS 通道負 責所有音訊、視訊資料的傳輸。例如AVI資訊框、音訊資 訊框等辅助資料，都是透過TMDS通道。而來源端透過 DDC通道來讀取接收端的延伸顯示辨識資料（Extended Display Identification Data, EDID)，進而得知接收端的功 能與特性。200937949 IX. Description of the Invention: [Technical Field] The present invention relates to a multimedia system, and more particularly to a multimedia system, a signal conversion device, and a method for converting a video control signal into a computer control signal to control a computer . [Prior Art] In recent years, the High Definition © Multimedia Interface (HDMI) has rapidly become the digital interface standard for consumer electronic devices in the world, and the HDMI device is visible everywhere in daily life. The source referred to in the HDMI specification is, for example, a digital versatile disc player, a set-top box, or an amplifier, and the sink (Sink) is, for example, a projector or a television. HDMI includes Transition Minimized Differential Signaling (TMDS) channels, Display Data Channel (DDC), and Consumer Electronics Control (CEC) channels. The TMDS channel is responsible for the transmission of all audio and video data. For example, AVI information frames, audio information frames and other ancillary materials are all transmitted through the TMDS channel. The source side reads the Extended Display Identification Data (EDD) of the receiving end through the DDC channel, and then knows the functions and characteristics of the receiving end.
來源端與接收端之間的CEC通道係經由CEC信號線 電性連接’CEC信號線上可電性連接多台HDMI裝置。CEC 5 200937949 仏號線提供了使用者對於HDMI裝置（或稱為CEC：裝置） 一種南階控制方式’例如單鍵播放（〇ne T〇uch play)、單鍵 錄影（One Touch Record)、系統資訊（SyStem Information)及 系統待命(System Standby)等，讓消費者對HDMI裝置能有 邏輯性層次更高的的控制方便性，這點在家庭劇院應用 上’對於機器之間的操作性助益良多。 HTPC 是 Home Theater Personal Computer 的縮寫，簡 單地說HTPC就是組建家庭劇院的電腦，可以連接投影 ®機、電視、音響、擴大機等裝置，並播放高清晰影片、聽 音樂、組建無線網路等功能。HTPC是通過電腦來替代傳 統家庭劇院中的信號源設備；同時，由於電腦靈活的配 置、強大的處理能力、優異的顯示品質、廉價的大容量存 儲、豐富的軟體等等，都是傳統的家庭劇院系統所不能比 擬的。所以越來越多家庭以HTPC做為家庭劇院的多媒體 令心。然而，當使用者欲利用HTPC瀏覽網頁或文書處理 Θ 等工作時’必需利用滑鼠及鍵盤等電腦輸入裝置來操作 HTPC ’與近年來推動「以單一電視遙控器即可控制所有 多媒體設備」之觀念相違背。 【發明内容】 本發明係有關於一種多媒體系統、信號轉換裝置及將 影音控制信號轉換成電腦控制訊號以控制一電腦之方 法。由於使用者透過電視遙控器即可操控電腦，因此，不 需額外地配置鍵盤或滑鼠等電腦輸入裝置。不僅可避免鍵 6 200937949 盤或滑鼠等電腦輪入 「以單-電視遙控器即可控制；心^達到近年來推動 根據本發明，提出—種信〇之觀念。 用以將影音控制信號轉換成電腦控制號轉換裝置

A lot. HTPC is the abbreviation of Home Theater Personal Computer. Simply put, HTPC is a computer that sets up a home theater. It can be connected to projectors, TVs, stereos, amplifiers, etc., and plays high-definition movies, listen to music, set up wireless networks and other functions. . HTPC replaces the signal source equipment in traditional home theaters with computers; at the same time, due to the flexible configuration of the computer, powerful processing capabilities, excellent display quality, inexpensive large-capacity storage, rich software, etc., it is a traditional family. The theater system is unmatched. Therefore, more and more families use HTPC as the multimedia of home theater. However, when users want to use HTPC to browse web pages or paperwork, etc., it is necessary to use a computer input device such as a mouse and keyboard to operate the HTPC. In recent years, it has promoted "all multimedia devices can be controlled with a single TV remote control". The concept is contrary. SUMMARY OF THE INVENTION The present invention is directed to a multimedia system, a signal conversion device, and a method of converting a video control signal into a computer control signal to control a computer. Since the user can control the computer through the TV remote control, there is no need to additionally configure a computer input device such as a keyboard or a mouse. Not only can the key 6 200937949 disk or mouse turn into the computer "can be controlled by a single-television remote control; the heart ^ has been promoted in recent years to promote the concept of a letterhead according to the present invention.
