A dynamic interface protocol supporting apparatus and method for providing an output signal with the same output terminal. [Prior Art] In modern digital systems, some chips (IC: integrated circuit, or simply chip) must provide output signals according to different interface protocols in different operation modes. For example, a chip in a digital system may directly output a DVD received from a digital versatile disc (servo) in an operating mode according to an integrated drive electronics (IDE: integrated drive electronics) protocol.

In conventional systems, due to differences in interface protocols, the wafers provide output signals at different outputs in different modes of operation. Basically, these modes of operation usually do not work at the same time, that is, the wafer is usually in a single mode of operation at any time. Since multiple outputs increase the number, complexity, and cost of the output pins of such a chip, we would like to have a device that can support multiple interfaces with the same output.

I29〇H 入端105接收視訊信號（在本實施例為動晝專家群組位元 串流no)，並且將此視訊信號傳導至視訊解碼器'1〇4。 視訊解碼器104接收此視訊信號，將其解碼為一解碼視訊 信號，然後將解碼視訊信號提供至視訊輸出介面1〇3。視 訊輸出介面103根據視訊協定將解碼視訊信號轉換為轉換 視汛k號，然後輸出轉換視訊信號。最後，開關1〇1將轉 換視訊信號傳導至輸出端106。 本實施例是由控制信號120告知開關1〇1與1〇2目前 的#作模式。得知目前的操作模式之後，開關1〇1與1〇2 就能決定輸入信號110的正確傳輸路徑。 由於裝置100無論在資料模式或視訊模式都使用相同 的輸出端106，只需要單一匯流排(bus)就能支援各種介面 協定。此外，裝置100的視訊解碼器104與視訊輸出介面 103可设疋為支援使用者自行定義的專屬視訊協定 (proprietary video protocol)以及對應的專屬視訊模式。如此 一來，裝置100就能為各種應用提供更高階的資料格式， 例如多聲道音響（multi-channel audio)、漸進視訊 (progressive video)、以及高晝質視訊（high_definiti〇n video) 〇 在本貫施例中’輸出端106的腳位(pins)是由多種操作 模式下的多種介面協定共用。圖4為裝置1〇〇在各種操作 模式下的輸出端106的腳位使用表。在本實施例中，裝置 100有一個資料模式和兩個視訊模式。在資料模式下，輸 出腳位傳遞標準IDE信號。在視訊模式2時，輸出腳位傳 1290437 15479twf.doc/g 遞標準CCIR656信號。至於視訊模式！是自行定義的專屬 模式，使用自行定義的專屬視訊協定。此專屬視訊協定的 信號由圖5說明。 視Λ褀式1的專屬協定使用y_cb_cr色域(domain) 來描述色彩，而非常見的紅綠藍色域(RGB d〇main)。其中 γ表示亮度（luminance)，而CB和CR表示色差（c〇1〇r difference)。每一個色彩的分量γ、CB、CR都量化__㈣ 為八位7L (資料位元2至9)。因為本實施例有足夠的輸 出腳位，上述的專屬視訊協定可提供完整色彩資訊。 在本實施例中，輸出端1〇6的腳位是由多種協定並 用。然而在本發明範圍中，若有足夠數量的輸出腳位，2 種介面協定可能會完全不制職。也就是說，每一個& 面協定各佔用—組輸出腳位，而且各組輸出腳位不相重疊。 如上所述，本實施例的裝置1〇〇無論在資料模^ ^個視訊模式㈣過輸出端⑽提供輸出信號 =100可用單—輸出端支援多種介面财，、 2爾種協定使用。如此裝置刚的腳位 對專的傳統裝置。以圖4的實施例為例。+氏於 =腳位’而專屬協定需要27個輸出腳位。藉::要4〇 出聊位’裝置100可將腳位數量從67降到40。= /、用輪 loo不但可降低_度與縣， 此襞置 應用彈性。 匕得、、死裝置有更高的 1290437 15479twf.doc/g 明技術領域具有通常知識者在看過上個實施例的裝置⑽ 的作之後’應能輕㈣瞭上述的動態介面駄支援方 法，在此就不多說明。 —另外，圖6為根據於本發明另一實施例的動態介面協 定支援U 600的不意圖。動態介面協定支援裝置嶋和 100的最大不同在於，裝i 100 {以單獨一組視訊輸出介 面103以及視訊解碼器1〇4支援多種視訊模式，而裝置⑹〇 包括多組視訊輸出介面603以及視訊解碼器6〇4，其中每 一組視訊輸出介面603與視訊解碼器6〇4各自支援一個不 同1視，模式。此外，裝置600是以多工器（multiplexer) 6〇 i 及解碼器（decoder) 602分別實現開關1〇1及1〇2的功能。 口在本實施例中，控制信號620 位元(bit)的數位信 ，，裝置600有2N-1個視訊模式以及一個資料模式。也就 是說，裝置600包括2N-1個視訊輸出介面6〇3以及 個視訊解碼器604。 σ動態介面協定支援裝置600的運作如下：首先，解碼 态602自輸入端605接收輸入信號61〇。解碼器6〇2會根 據控制信號620得知目前的操作模式。若裝置6〇〇目前處 於某個視訊模式，解碼器6〇2會將輸入信號61〇傳導至對 應此視訊模式的視訊解碼器6〇4。另一方面，若裝置6〇〇 目前處於資料模式，解碼器602會將輸入信號610傳導至 多工器601。同樣的，多工器601會根據控制信號62〇得 知目前的操作模式。若裝置6〇〇目前處於某個視訊模式， 多工器601會將對應此視訊模式的視訊輸出介面603的輸 I29〇m f.doc/g 出傳導至輸出端606做為輪出信號6n 式’則多工器601會將解碼器“ί 出傳V至輸出知606做為輪出信號611。 在貝IV、的貝施上’可以將公用腳位透過解碼器/多工界 來達成共享的目的。以圖4中白^ H)ED7/VDCB9/VIDEQJ>XD[9]之共賴出腳㈣言，可利 +用：4X丄Ϊ多工器’並利用一個兩位元的控制信號做資料 切換至輸出端的控職作，其他的制輸㈣亦可透過類 似=方式達摘需，料用輸人端之實施方朗可利用解 碼器來進行視訊錢與:#料錢的城。此外，本發明較 佳實施例巾的控制信號可由相關系统（例如cd_腿、 DVD Player等光電系統），依據目前的操作模式(例如視訊 模式或資料财)來發^。熟f本發明技術者#可視實際需 求對本發明杈佳貫施例進行變更，但所有等效修飾仍應包 含於本發明申請專利範圍中。 本發明可應用於任何可讀取光碟中資料的光電系 統’例如 CD-ROM 碟機(drive)、CD-RW 碟機、DVD-ROM ，機、DVD+R碟機、DVD+RW碟機、或DVD-RAM碟機 等系統之中，透過共用輸出/入端來切換作為資料信號與視 號之切換機制，但熟習本發明技術者當可依據其需 求，將本發明方法應用在其光電系統中。 ^由以上說明可知，動態介面協定支援裝置600無論在 貢料模式或任何一個視訊模式都透過輸出端606提供輸出 L 5虎。因此動悲介面協定支援裝置6〇〇和上一個實施例的The I29〇H input terminal 105 receives the video signal (in this embodiment, the active expert group bit stream no), and transmits the video signal to the video decoder '1〇4. The video decoder 104 receives the video signal, decodes it into a decoded video signal, and then provides the decoded video signal to the video output interface 1〇3. The video output interface 103 converts the decoded video signal into a converted view k number according to the video protocol, and then outputs the converted video signal. Finally, switch 1〇1 conducts the converted video signal to output 106. In this embodiment, the current signal mode of the switches 1〇1 and 1〇2 is informed by the control signal 120. After learning the current mode of operation, switches 1〇1 and 1〇2 determine the correct transmission path for input signal 110. Since the device 100 uses the same output 106 in both the data mode and the video mode, only a single bus can be used to support various interface protocols. In addition, the video decoder 104 and the video output interface 103 of the device 100 can be configured to support a user-defined proprietary video protocol and a corresponding dedicated video mode. In this way, the device 100 can provide higher-order data formats for various applications, such as multi-channel audio, progressive video, and high-definition video (high_definiti〇n video). In the present embodiment, the pins of the output terminal 106 are shared by a plurality of interface protocols in a plurality of modes of operation. Figure 4 is a table of the use of the position of the output 106 of the device 1 in various modes of operation. In this embodiment, device 100 has one data mode and two video modes. In data mode, the output pin transmits the standard IDE signal. In video mode 2, the output pin transmits 1290437 15479twf.doc/g to the standard CCIR656 signal. As for the video mode! It is a self-defined proprietary mode that uses a proprietary video protocol that is defined by itself. The signal for this proprietary video protocol is illustrated in Figure 5. The exclusive protocol of view 1 uses the y_cb_cr gamut to describe colors, rather than the usual red, green, and blue fields (RGB d〇main). Where γ denotes luminance, and CB and CR denote color difference (c〇1〇r difference). The components γ, CB, and CR of each color are quantized __(four) to eight bits 7L (data bits 2 to 9). Since this embodiment has sufficient output pins, the above-mentioned proprietary video protocol can provide complete color information. In the present embodiment, the pin of the output terminal 1〇6 is used in combination with a plurality of protocols. However, within the scope of the present invention, if there are a sufficient number of output pins, the two interface agreements may be completely unworked. That is to say, each & surface agreement occupies the group output pin, and the output pin groups of each group do not overlap. As described above, the apparatus 1 of the present embodiment provides an output signal =100 in the data mode (4) over the output terminal (10). The single-output terminal supports a plurality of interfaces, and the two types of protocols are used. This device is just the right foot for the traditional device. Take the embodiment of FIG. 4 as an example. + is at = pin' and the exclusive agreement requires 27 output pins. Borrow:: 4 〇 Talks' device 100 can reduce the number of feet from 67 to 40. = /, using the wheel loo can not only reduce the _ degree and the county, this device applies flexibility.

In addition, FIG. 6 is a schematic diagram of the dynamic interface agreement support U 600 according to another embodiment of the present invention. The biggest difference between the dynamic interface protocol support device and the 100 is that the i 100 {supports multiple video modes with a single set of video output interfaces 103 and video decoders 1 and 4, and the device (6) includes multiple sets of video output interfaces 603 and video. The decoder 6〇4, wherein each set of video output interface 603 and video decoder 6〇4 respectively support a different one view mode. Further, the device 600 functions as a multiplexer 6 〇 i and a decoder 602 to implement switches 1 〇 1 and 1 〇 2, respectively. In this embodiment, the control signal 620 is a bit-bit digital signal, and the device 600 has 2N-1 video modes and a data mode. That is, the device 600 includes 2N-1 video output interfaces 6〇3 and video decoders 604. The operation of the sigma dynamic interface agreement support device 600 is as follows: First, the decode state 602 receives the input signal 61 from the input terminal 605. The decoder 〇2 will know the current mode of operation based on the control signal 620. If the device 6 is currently in a certain video mode, the decoder 6〇2 will transmit the input signal 61〇 to the video decoder 6〇4 corresponding to the video mode. On the other hand, if device 6 is currently in data mode, decoder 602 will pass input signal 610 to multiplexer 601. Similarly, multiplexer 601 will know the current mode of operation based on control signal 62. If the device 6 is currently in a certain video mode, the multiplexer 601 will transmit the output I29〇m f.doc/g corresponding to the video output interface 603 of the video mode to the output terminal 606 as the round signal 6n. 'The multiplexer 601 will send the decoder "ί V to the output 606 as the round signal 611. On the Bay IV, the Besch can use the common pin to achieve sharing through the decoder / multi-work The purpose is to use the white ^ H) ED7 / VDCB9 / VIDEQJ > XD [9] in Figure 4 (4), the use of: 4X 丄Ϊ multiplexer ' and use a two-digit control signal The data is switched to the output of the control job, and other systems (4) can also be picked up by the similar method. The implementer of the input terminal can use the decoder to carry out the video money and the city. In addition, the control signal of the preferred embodiment of the present invention can be sent by the relevant system (for example, cd_leg, DVD Player, etc.) according to the current operation mode (for example, video mode or data wealth).者#The actual invention needs to be changed for the preferred embodiment of the invention, but all equivalent modifications should still be included. The invention is applicable to any photoelectric system capable of reading data in an optical disc, such as a CD-ROM drive, a CD-RW drive, a DVD-ROM, a machine, a DVD+R disc. In a system such as a machine, a DVD+RW drive, or a DVD-RAM drive, the switching mechanism of the data signal and the visual number is switched through the shared output/input, but those skilled in the art can according to their needs. The method of the present invention is applied to its optoelectronic system. ^ As can be seen from the above description, the dynamic interface protocol support device 600 provides an output L 5 through the output terminal 606 in either the tribute mode or any of the video modes. 6〇〇 and the previous embodiment
