M276283 八、新型說明： 【新型所屬之技術領域】 本創作係關於一種影音播放裝置，尤其是有關於内建於電腦 内、不須電腦開機、直接播放電腦儲存裝置内影音資訊之裝置。 【先前技術】 由於如MP3與MPEG等數位編碼技術的進步，傳統的類比 的聲音與視訊訊號，可以很容易的被數位化而加以傳輸與儲存， 也因此有大量的影音資訊能夠透過網際網路傳輸與交換，然後以 檔案的形式儲存在電腦的儲存裝置（像是硬碟）中。電腦也從單 純的運算工具，變成能夠播放這些數位影音資訊的多媒體中心。 只是，電腦要播放這些儲存在其儲存裝置内的影音檔案，使 用者必須先打開電腦電源（亦即開機），等電腦把作業系統執行起 來，然後透過電腦的人機界面（像是螢幕、鍵盤、滑鼠等），找到 所要播放的音樂、或視訊檔案，然後啟動相關的播放程式，才能 透過電腦的喇叭、螢幕聆聽或收看這些影音資訊。這是一個相當 冗長與費時的過程。另外，當聆聽或收看完畢後，也需要類似的 冗長過程將電腦關機。因此，一種能將電腦當成家用電器一般即 開即用的需求於焉產生。 而且隨著各種新穎的電腦儲存裝置被廣泛的使用，影音資訊 可以被存放在記憶卡（例如數位攝影機所拍攝下來的照片或是 MP3格式的音樂）、雷射光碟（例如VCD、DVD影片或音樂CD)、 M276283 硬碟（從網路上下載的影音檔案）等種種儲存裝置上，若能省略 冗長的開關機程序而直接加以播放這些儲存裝置裡的影音檔案， 則不僅省時，也由於使用電腦本身的螢幕或音效裝置播出，因而 可以節省額外購買相關影音設備的支出。而且，隨著筆記型電腦 之廣受歡迎，如能使筆記型電腦具有類似的功能，則筆記型電腦 更成為行動的影音播放裝置，其效果將更為宏大。 【新型内容】 本創作之主要目的在提供一種内建於電腦内的裝置，在電腦 未開機的狀態，可以直接播放電腦的硬式磁碟機以及其他的儲存 裝置内所儲存的影音資訊。 本裝置係自電腦的電源供應器擷取所需電力，或者，如果電 腦具有電池（如筆記型電腦）而電腦的電源供應器無法提供電力 (如停電、或沒有插上電源插頭），本裝置則可以從電池擷取所需 的電力。 本裝置所設計讀取的，包括固接於電腦的儲存裝置，以及其 他非固接的，透過USB、 1394、平行埠、串列埠等界面的外部 儲存裝置（如USB Flash Drive、USB界面的外接硬碟等）。本裝 置所支援的固接的儲存裝置係指内建於電腦内的儲存裝置，而其 儲存媒介可以是固定於裝置内（如硬式磁碟）或是可抽換的（如 記憶體卡、軟式磁碟片、雷射光碟片等）。 本裝置所播放出來的影音訊號，可以透過電腦的螢幕（如筆 M276283 記型電腦的内建液晶勞幕、或是一般桌上電腦透過vga镜線所 連接的螢幕）與音效裝置（如㈣呈現出來，或是，如果電腦 有具備的話，透過電腦的視訊輸出界面（像是Wde_插孔）與 =效輪出界面（像是耳機插孔、丨ine_插孔)所連接的電視、音響 荨呈現出來。 置在電腦機身上提供數個控制按鍵，以作為本裝置的人 、工1丨Φ或者’本|置亦提供一遙控器，利用適當的空中界 面(anMmerfaee)(如紅外線、藍料協定）以從—適當距離外遙

一些通訊界面（例如網路埠等），惟這些細節並無助於本創作精神 的說明，故於此省略。 電源供應器120是提供所有電腦1上述元件的所需電力。這 個電源供應器120是接收交流的市電，轉換並供應上述元件所需 的各種大小的直流電壓。如果是筆記型電腦的話，電腦1還可以 包含一電池130，以便在停電時或是無法取得交流市電時繼續供 電給電腦1的上述元件。電源供應器120與電池130與上述各個 元件之間的電力連接並未圖示於第1圖中。 M276283 第2圖係依據本創作一較佳實施例之電腦架構示意圖（第2 圖也是以筆記型電腦為例）。和第1圖比較起來，依據本創作的電 腦2係增加了一個影音播放模組200，這個影音播放模組200也 是接續於匯流排110上。經由匯流排110，此影音播放模組200 得以存取儲存於固接或非固接式儲存裝置裡的影音檔案或是具有 特定播放格式的儲存媒介。同樣經由此匯流排110，此影音播放 模組200所解譯出來的影音訊號，得以從電腦2内建的影像顯示 裝置50與音效裝置60呈現出來，或者也可以從視訊輸出界面70 與音效輸出界面80由外部的影音設備呈現。 影音播放模組200至少包含有一處理晶片組210與一控制界 面250。處理晶片組210裡至少包含一具有影音解碼功能的微處 理器220、一唯讀記憶體230、與一隨機存取記憶體240。微處理 器220負責讀取儲存於儲存裝置裡的影音檔案或是具有特定播放 格式的儲存媒介、加以解譯、然後從影像顯示裝置50與音效裝置 60,或者也可以從視訊輸出界面70與音效輸出界面80播放出來。 唯讀記憶體230記錄的是微處理器220執行各種各種工作所需的 韌體。隨機存取記憶體240則是提供微處理器220運作過程中所 需的暫存空間。 控制界面250負責開關與控制微處理器220的各種動作。控 制界面250包含一位於電腦2機身上的控制按鍵組260，以供使 用者透過控制界面250操控微處理器220的動作。這個控制按鍵 組260包含複數個按鍵以提供下列功能：開啟或關閉影音播放模 10 M276283 組200的運作（控制是 gj... , t 處理器220)、選擇所要讀取的 固接式或非固接儲存裝置、選擇輸'

M276283 所以，在任何時刻，影音播放模組200和電腦2的其他元件是無 法同時運行的。這裡有一點需要注意的是，由於影音播放模組200 會用到電腦2的下列元件：匯流排110、固接式儲存裝置90、非 固接式儲存裝置1〇〇、視訊輸出界面70、音效輸出界面80、影像 顯示裝置50、音效裝置60，所以當供電給影音播放模組200時， 電腦2有另外的路徑從電源供應器120與電池130供電給上述這 些元件（在第2圖以虛線表示），所以這些元件還是可以繼續運 作。在影音播放模組200運作過程中如果突然打開電腦的電源開 關，則影音播放模組200會因為失去了電力的供給立刻停止動作。 這裡還需要注意的一點是，對於儲存於具有目錄結構的影音 檔案，由於不容易利用有限的控制按鍵在複雜的目錄結構中搜尋 所要播放的影音檔案，所以本創作對於存放於像是硬碟機裡的影 音檔案，這些影音檔案必須位於一特定的位置（例如根目錄），才 能予以播放。使用者然後可以使用控制按鍵（像是跳到上一個檔 案、或是跳到下一個檔案）來跳過該特定位置裡不想要播放的檔 案，直到跳到所要的檔案為止。 本創作的影音播放模組200會自動依據影音資訊的格式（例 如MP3音樂、MPEG電影等）自動選擇適當的播放模式，完全不 需要使用者的選擇。 本創作的一基本播放流程說明如下：首先，電腦的電源開關 必須是關閉的，這時影音播放模組200會有電力的供給，然後用 機身的控制按鍵或是遙控器進一步開啟對微處理器220的供電， 12 M276283 這時影音播放模組200處於待命的狀態，將所要播放的光碟片放 入光碟中、或是插入記憶體卡片等（若是播放硬碟的影音檔案則 不需要這個步驟），繼續用機身的控制按鍵組260或是遙控器290 選擇所要讀取的儲存裝置以及所要播放的檔案，接著選擇影音訊 號所要輸出的裝置，然後按下控制按鍵組260的播放按鍵即可。 其他操作流程如切換播放其他固接或非固接式儲存裝置内的影音 資訊或是結束播放，可以很直接的理解出來，於此不再贅述。 藉由以上較佳具體實施例之詳述，係希望能更加清楚描述本 創作之特徵與精神，而並非以上述所揭露的較佳具體實施例來對 本創作之範疇加以限制。相反地，其目的是希望能涵蓋各種改變 及具相等性的安排於本創作所欲申請之專利範圍的範疇内。

Description of the new type: [Technical field to which the new type belongs] This creation is about an audio and video playback device, especially a device that is built in a computer and does not require the computer to boot, and directly plays the audio and video information in the computer storage device. [Previous technology] Due to the advancement of digital coding technologies such as MP3 and MPEG, traditional analog sound and video signals can be easily digitized for transmission and storage, and therefore a large amount of audiovisual information can be transmitted through the Internet Transfer and exchange, and then store it as a file in the storage device of the computer (such as a hard disk). The computer has also changed from a simple computing tool to a multimedia center capable of playing these digital video and audio information. However, in order for a computer to play these video and audio files stored in its storage device, the user must first turn on the computer (that is, turn it on), wait for the computer to run the operating system, and then use the computer's human-machine interface (such as the screen and keyboard) , Mouse, etc.), find the music or video file you want to play, and then start the relevant player to listen or watch the audio and video information through the computer's speakers and screen. This is a fairly lengthy and time-consuming process. In addition, after listening or watching, a similar lengthy process is required to shut down the computer. Therefore, a demand for computers that can be used as home appliances is generally out of the box. And with the widespread use of various novel computer storage devices, audiovisual information can be stored on memory cards (such as photos taken by digital cameras or music in MP3 format), laser discs (such as VCD, DVD movies, or music) CD), M276283 hard disk (video files downloaded from the Internet) and other storage devices, if you can omit the lengthy startup process and play the video files in these storage devices directly, it will not only save time, but also use a computer Broadcast on your own screen or audio device, so you can save extra money on related audio and video equipment. Moreover, with the popularity of notebook computers, if the notebook computers can be made to have similar functions, the notebook computer will become a mobile audio and video playback device, and the effect will be even greater. [New content] The main purpose of this creation is to provide a device built into the computer. When the computer is not turned on, it can directly play the video and audio information stored in the computer's hard disk drive and other storage devices. This device extracts the required power from the computer's power supply, or if the computer has a battery (such as a laptop) and the computer's power supply cannot provide power (such as a power outage or the power plug is not plugged in), the device You can get the power you need from the battery. The design and read of this device include storage devices fixed to the computer, and other non-fixed external storage devices (such as USB Flash Drive, USB interface, etc.) through USB, 1394, parallel port, serial port and other interfaces. External hard drive, etc.). The fixed storage device supported by this device refers to the storage device built in the computer, and its storage medium can be fixed in the device (such as a hard disk) or removable (such as a memory card, a soft disk) Magnetic disks, laser discs, etc.). The audio and video signals played by this device can be displayed on the computer screen (such as the built-in LCD screen of the pen M276283 notebook computer, or the screen connected to a general desktop computer through a vga mirror cable) and sound effects devices (such as ㈣ Out, or, if the computer has it, the TV and audio connected to the computer ’s video output interface (such as the Wde_ jack) and = effect wheel out interface (such as the headphone jack, 丨 ine_ jack). The Xun appears. There are several control buttons provided on the computer body to serve as the person, worker 1 or Φ of this device. This device also provides a remote control, using an appropriate air interface (anMmerfaee) (such as infrared, blue Material agreement) to remotely from the appropriate distance & the clothing set. The remote control and the computer body can be further-included-a small display device (such as LED, or LCD display) to provide the operation of the device Information for users 0 The advantages and spirit of this creation can be further understood through the following series of detailed descriptions and the attached drawings. [Embodiment] Figure 1 is a schematic diagram of a known computer architecture. As shown in Figure 1 As shown in the figure, the conventional computer 1 contains at least-the processor is responsible for processing the main computing masterpiece, and the read-only memory 20 includes the computer!

M276283 This can be a built-in LCD screen (if the computer 1 is a laptop) or connected via a VGA cable. LCD screen, CRT screen, or projector, etc. (not shown). The sound effect device 60 is a built-in computer 9 or other speaker device. Figure 1 shows a notebook computer as an example. Video output interface 70 is to send the video signal of computer 1 to external video devices through this interface. This video output interface includes (but is not limited to) the video out terminal, S terminal, RGB terminal, DVI interface, or a second VGA Interfaces, etc. These interfaces can be used to connect (but not limited to) televisions, video recorders, projectors, etc. The sound output interface 80 is used to transmit the sound signal of computer 1 through this interface to external sound effects devices. This The sound output interface includes (but is not limited to) line out terminals, headphone jacks, etc. These interfaces can be used to connect (but not limited to) audio, recorders, etc. The fixed storage device 90 refers to a fixed installation on a computer 1 Internal storage device, this device can be further divided into two types, one is that its storage medium cannot be exchanged, and the conventional hard disk drive belongs to this non-replaceable fixed storage device. The other is storage The media can be swapped, including, for example, a floppy disk drive built into the computer 1, a read-only laser drive (such as a CD-ROM, DVD-ROM disc), or a read-write Laser disc drive (such as CD-RW, DVD-RW, DVD + RW, etc.), other similar computer built-in, read-write memory cards (such as MS card, SD card Etc.) card readers also fall into this category Fixed storage device. In addition, other storage devices include a non-fixed storage device 100. These M276283 non-fixed storage devices are external storage devices (such as USB Flash Drive, external hard disk with USB interface, etc.) connected to computer 1 through interfaces such as USB, 1394, parallel port, and serial port. The above-mentioned fixed and non-fixed storage devices are supported by this device. In these storage devices, some of the stored data is arranged in a hierarchical directory structure (such as a hard disk). Audiovisual information is stored in this directory structure in the form of files. For example, the file format of music or sound can be (But not limited to) MP3, WAV, MIDI file formats, file formats for still images can be (but not limited to) JPEG, TIFF, etc., and file formats for video can be (but not limited to) Motion JPEG, MPEG, etc. There are also some storage devices whose storage media have a specific format, such as the playback format of DVDs and VCDs. Each component of the computer 1 described above is connected to a bus 110 to transmit or exchange various data with each other. Please note that Figure 1 has omitted many details in the actual computer, such as the chipset of the North-South Bridge, various I / O controllers, and some communication interfaces (such as network ports), but these details are not helpful The description of the creative spirit is omitted here. The power supply 120 is required to supply all the above-mentioned components of the computer 1. This power supply 120 receives AC mains power, converts and supplies DC voltages of various magnitudes required by the aforementioned components. In the case of a notebook computer, the computer 1 may further include a battery 130 to continue supplying power to the above-mentioned components of the computer 1 during a power outage or when AC mains power is not available. The power connections between the power supply 120 and the battery 130 and the above components are not shown in the first figure. M276283 The second picture is a schematic diagram of the computer architecture according to a preferred embodiment of the present invention (the second picture also uses a notebook computer as an example). Compared with Fig. 1, the computer 2 series based on this creation adds an audio and video playback module 200, and this audio and video playback module 200 is also connected to the bus 110. Via the bus 110, the audio and video playback module 200 can access the audio and video files stored in the fixed or non-solid storage device or a storage medium with a specific playback format. Similarly, through the bus 110, the audio and video signals interpreted by the audio and video playback module 200 can be displayed from the video display device 50 and the audio effect device 60 built in the computer 2, or they can be output from the video output interface 70 and audio effect output. The interface 80 is presented by an external audio and video device. The audio-visual playback module 200 includes at least a processing chipset 210 and a control interface 250. The processing chipset 210 includes at least a microprocessor 220 having a video decoding function, a read-only memory 230, and a random access memory 240. The microprocessor 220 is responsible for reading the audio and video files stored in the storage device or a storage medium with a specific playback format, interpreting them, and then from the image display device 50 and the sound effect device 60, or from the video output interface 70 and sound effects The output interface 80 is played. The read-only memory 230 records the firmware required by the microprocessor 220 to perform various tasks. The random access memory 240 is used to provide temporary storage space required by the microprocessor 220 during operation. The control interface 250 is responsible for switching and controlling various actions of the microprocessor 220. The control interface 250 includes a control button group 260 located on the body of the computer 2 for the user to control the actions of the microprocessor 220 through the control interface 250. This control button group 260 contains a number of buttons to provide the following functions: open or close the operation of the video playback mode 10 M276283 group 200 (control is gj ..., t processor 220), select the fixed type or non-read to read Fixed storage device, choose to enter 'pause / resume, skip to the previous-a mark-, set or, 1 & put stop, H, "丨 η-wood or month 丨]-paragraph, skip to the next file Or next ... ㈣ the first 4 cases or the first paragraph, etc. Nu Luo, skip to the next file or the next control interface 250 can also enter a dry cry 2 V package know 2 provides a small flat state 270 on the body (For example, a LCD that can be fixed at 26 or X). It is equipped with control buttons and 260 grids. It is used as a process towel in the control interface. It provides relevant operations to the user, such as a playback file or疋 Error message, etc. Control interface 250 28〇 ^ Step by step-Provide a wireless remote control receiving interface on the body of computer 2, using infrared or Bluetooth communication methods, use _remote control to control the video playback module 200. Remote Cry 2 () Λ and a work on the soil provided In addition to the same control button group as the control button group 260, it can also be provided with a small display to provide operating information. 彳 ϋ Important point of operation 疋 When the computer 2 is not turned on, it can also play audio and video information. Therefore, there is a specially designed switch 300 on the road between the power supply ⑽ and the battery 13G. This switch fan is linked with the power switch (not shown) of computer 2. When the power switch of computer 2 is turned on, The switch 300 connects the power of the power supply 12G and the battery m to each component of the computer 2, but cuts off the power supply to the video playback module. Therefore, #the video playback module cannot be operated when the computer is running. However, when the power of computer 2 is turned off, the switch 300 is to connect «Supply H 电 and TV 3G with electricity to the county material playback module 200 (indicated by dashed lines in Figure 2), but cut off the other components of computer 2 Power supply. M276283 Therefore, at any time, other components of the audio and video playback module 200 and computer 2 cannot run at the same time. One thing to note here is that because the audio and video playback module 200 will be used under the computer 2 Components: bus 110, fixed storage device 90, non-fixed storage device 100, video output interface 70, audio output interface 80, video display device 50, audio device 60, so when power is supplied to the audio and video playback module At 200 hours, the computer 2 has another path to power these components from the power supply 120 and battery 130 (indicated by dashed lines in Figure 2), so these components can continue to operate. During the operation of the audio and video playback module 200, if Suddenly turning on the power switch of the computer, the audio and video playback module 200 will stop immediately because of the loss of power supply. Another thing to note here is that for the audio and video files stored in the directory structure, it is not easy to use limited control buttons. Search for the audio and video files to be played in the complicated directory structure. Therefore, for the audio and video files stored in the hard disk drive in this creation, these audio and video files must be located in a specific location (such as the root directory) before they can be played. The user can then use the control buttons (such as skip to the previous file or skip to the next file) to skip the files that are not to be played in that particular location until the desired file is skipped. The created audio and video playback module 200 automatically selects an appropriate playback mode according to the format of the audio and video information (such as MP3 music, MPEG movie, etc.), without the need for user selection. A basic playback process of this creation is explained as follows: First, the power switch of the computer must be turned off. At this time, the audio and video playback module 200 will be powered, and then use the control buttons on the body or the remote control to further turn on the microprocessor. The power supply of 220, 12 M276283 At this time, the audio and video playback module 200 is in a standby state, put the disc to be played into the disc, or insert a memory card, etc. (this step is not necessary for playing audio and video files on the hard disk), Continue to use the control button group 260 or remote control 290 of the body to select the storage device to be read and the file to be played, then select the device to output the audio and video signals, and then press the play button of the control button group 260. Other operating procedures, such as switching playback of video and audio information in other fixed or non-fixed storage devices, or ending playback, can be understood directly, and will not be repeated here. With the detailed description of the above preferred embodiments, it is hoped that the characteristics and spirit of this creation can be described more clearly, and the scope of this creation is not limited by the preferred embodiments disclosed above. On the contrary, the intention is to cover various changes and equitable arrangements within the scope of the patent for which this creation is intended.
