Description

多切换显示控制装置、矩阵式显示控制装置及其控制方法 Multi switching display control means, the control matrix display apparatus and a control method

技术领域 FIELD

[0001] 本发明是有关于一种影音来源切换装置及其控制方法,特别是有关于一种高带宽数字内容保护(HDCP)的多切换、矩阵式显示控制装置及其控制方法。 [0001] The present invention relates to apparatus and method for controlling video and audio source switch, particularly to a high-bandwidth digital content protection (HDCP) multiple switching matrix display device and its control method.

背景技术 Background technique

[0002] 随着使用需求及操作环境的考虑,越来越多使用者在播放影音信号时,常搭配多影音来源切换系统来提供给使用者更多的使用需求。 [0002] With the use of considering the needs and operating environment, more and more users when playing audio and video signals, often with multi-source audio and video switching system to provide the user with additional needs. 在多影音来源切换系统的架构上,大致是包含多个输入端、切换电路与多个输出端。 Multiple audio sources in the framework of the switching system, generally comprising a plurality of input terminals, a plurality of output terminals of the switching circuit. 各输入端连接有一个影音播放装置,而各输出端则是连接一个显示装置(如屏幕、投影机等),通过切换电路选择影音播放装置提供影音来源至显示装置,以使显示装置显示欲观赏的影音内容。 Each input terminal is connected to a video playback device, and each output terminal is connected to a device (such as a screen, a projector, etc.) displayed by the switching circuit selects the video playback device to provide video and audio source to the display device, so that the display means displays to be viewed audio and video content.

[0003] 另一方面,随着影音信号格式的发展,目前使用者已可以拥有数字化高清晰度(High Definit1n)影片所带来的视觉享受。 [0003] On the other hand, with the development of audio and video signal formats, the current user can already have a visual digital high definition (High Definit1n) brought the movie to enjoy. 而目前用来储存高清晰度影音信号的储存媒体,有蓝光规格(Blu-ray Disc)及高清晰度光盘规格(HD DVD)的光盘。 The current storage media for storing high-definition video and audio signals, Blu-ray specifications (Blu-ray Disc) and high-definition optical disc format (HD DVD) disc. 此外,为了确保数字化的影音信号在传输时不至于遭到非法拷贝,目前也制定了高带宽数字内容保护(High-bandwidth Digital Content Protect1n,HDCP)的保护机制。 In addition, in order to ensure that the digital audio and video signal transmission would not have been illegal copies, it is also developed a high-bandwidth digital content protection (High-bandwidth Digital Content Protect1n, HDCP) protection mechanisms. 换句话说,影音输入装置及影音输出装置两者都必须要有HDCP认证(内建有HDCP密钥芯片)才能顺利地进行传递有HDCP保护的影音信号。 In other words, both the video and the audio output device an input device must have the HDCP authentication (chip built HDCP key) has to be passed smoothly HDCP protected video signal. 若任何一个不配备此密钥芯片的话,则所输出的影像画素有可能降低,甚至不能播放等。 If any of this key is not equipped with a chip, then the output image pixel is likely to reduce, or even playback. 附带一提的是,在HDCP保护机制的技术上是设计约2秒就会进行验证一次,因此影音输入装置及影音输出装置之间必须持续维持联机且保持开机状态才能使验证工作顺利完成,而让播放作业完整进行。 Incidentally is technically in HDCP protection mechanisms are designed for about two seconds will be validated once, it is necessary to continue to maintain the connection between the audio and video input devices and audio output device and leave it on in order to verify the successful completion of the work, and let play carry out a complete job.

[0004] 综上所述,如果使用者欲将多个受HDCP保护的影音来源于一个显示装置上进行切换显示时,则将可能发生以下问题。 [0004] In summary, if the user wants more media HDCP protected from a switching display on the display device, then the following problem may occur. 由于目前的多影音切换系统的设计是直接将影音播放装置的密钥信息传递给显示装置来进行验证。 Since the current design is a multi-audio switching system key information directly to the video playback device is transmitted to the display device for verification. 如此一来,当由目前提供影音来源至显示装置的影音播放装置切换为另一个影音播放装置时,因为后切换的影音播放装置必须与当前的显示装置重新进行验证,而导致后切换的影音播放装置会重新播放影音内容。 Thus, when the current provided by the video source audio playback means is switched to another video playback device to display, after the handover because the video playback device must be re-verification means and the current display, resulting in switching the audio and video playback the device will replay the audio and video content.

[0005] 因此,针对多影音来源切换系统来讲,要如何维持有HDCP的验证保护机制,并且让多个影音播放装置能够于所选择的显示装置上进行播放,且于进行切换时不中断影音播放装置当前所播放的影音内容,成为研究人员待解决的问题之一。 [0005] Therefore, for multi-source audio and video switching system is concerned, to verify how to maintain an HDCP protection mechanisms, and allow multiple audio and video playback devices can be played in the selected display device, without interrupting the video and when to switch player currently playing audio and video content, and become one of the researchers to be solved.
