Description

本発明は、コピー防止信号を含むAV信号受信機にてAV出力許可の認証結果をユーザ提示する方法と装置とを有するAV信号受信装置に関する。   The present invention relates to an AV signal receiving apparatus having a method and apparatus for presenting an authentication result of AV output permission to a user at an AV signal receiver including a copy prevention signal.

近年、いわゆるデジタル家電が急速に普及している。   In recent years, so-called digital home appliances are rapidly spreading.

デジタル家電とはDVD(Digital Versatile Disc)プレーヤーやSTB(Set Top Box)などのソース機器からLCD(液晶ディスプレイ)やPDP(プラズマディスプレイパネル)、DLPプロジェクターなどのシンク機器まで、AV信号をデジタル信号処理することが特徴とするAV機器のことである。このようなデジタル家電の特徴として高画質・高音質が挙げられる。   Digital home appliances process digital AV signals from source devices such as DVD (Digital Versatile Disc) players and STB (Set Top Box) to sink devices such as LCD (liquid crystal display), PDP (plasma display panel), and DLP projectors It is an AV device characterized by As a feature of such digital home appliances, there are high image quality and high sound quality.

しかし、デジタル機器の目覚しい普及にも関らず、ソース機器とシンク機器との間はコンポーネント接続などのアナログ接続が一般的である。アナログ接続はノイズに弱く、高画質・高音質のAV信号が劣化する可能性がある。   However, despite the remarkable spread of digital devices, analog connection such as component connection is generally used between the source device and the sink device. Analog connections are vulnerable to noise, and high-quality and high-quality AV signals may be degraded.

この問題を解決するためにHDMI(High−Definition Multimedia Interface)規格が定められた。HDMIはソース機器とシンク機器をデジタル接続することが大きな特徴である。   In order to solve this problem, a High-Definition Multimedia Interface (HDMI) standard has been defined. A major feature of HDMI is that the source device and the sink device are digitally connected.

また、デジタル接続の場合は不正コピーの懸念があるが、HDMIではコピー防止技術であるHDCP(High−bandwidth Digital Contents Protection)を採用することにより、認証に成功したソース・シンク間でのみAV信号の送受信を可能にした。   In the case of digital connection, there is a concern of unauthorized copying, but HDMI employs HDCP (High-bandwidth Digital Contents Protection), which is a copy prevention technology, so that the AV signal can be transmitted only between the source and sink that have been successfully authenticated. Enables sending and receiving.

しかし、HDCP認証がなんらかの原因により失敗した場合、ソース機器からシンク機器へのAV出力が停止されるが、ユーザはAV出力されない原因を知ることができないという問題があった。また、認証に失敗した場合にソース機器から視聴不可メッセージをシンク機器にOSD出力する技術があるが、シンク機器がディスプレイ装置を持たない場合にはユーザはメッセージを認知できないという問題もあった。
特開2004−95159号公報
However, when HDCP authentication fails for some reason, AV output from the source device to the sink device is stopped, but there is a problem that the user cannot know the cause of the AV output not being performed. In addition, there is a technique for OSD output of a non-viewable message from the source device to the sink device when authentication fails, but there is also a problem that the user cannot recognize the message if the sink device does not have a display device.
JP 2004-95159 A

解決しようとする問題点は、認証失敗した場合に、ソース機器が視聴不可メッセージをOSD出力しなかったり、シンク機器にディスプレイ装置がなかったりするとユーザが認証失敗を認知できない点である。   The problem to be solved is that when the authentication fails, the user cannot recognize the authentication failure if the source device does not output an OSD message or the sink device does not have a display device.

前述した課題を解決するために、本発明では、ソース機器とデジタル接続するためのデジタルインタフェースと、前記デジタルインタフェースを使用して出力されるAV信号の出力許可認証を行う認証装置と、前記認証装置により実行された認証結果をユーザに提示するための認証結果表示装置と、前記認証結果を受け取り前記認証結果表示装置に出力するための制御装置とを具備することにより、シンク機器側で認証の成否を判別し、その結果をユーザに認知可能な形式で提示することを最も主要な特徴とする。   In order to solve the above-described problems, in the present invention, a digital interface for digital connection with a source device, an authentication device for performing output permission authentication of an AV signal output using the digital interface, and the authentication device Authentication result display device for presenting the authentication result executed by the user to the user, and a control device for receiving the authentication result and outputting it to the authentication result display device. The main feature is that the result is discriminated and the result is presented to the user in a recognizable format.

前記デジタルインタフェースはHDMI規格に従っている場合を含む。また、前記認証装置はHDCP規格に従っている場合を含む。更に、前記認証結果表示装置はLCDやPDP、DLPプロジェクターといったディスプレイ装置を含む。また、前記認証結果表示装置はLEDやスピーカも含む。   The digital interface includes a case that conforms to the HDMI standard. In addition, the authentication apparatus includes a case that complies with the HDCP standard. Further, the authentication result display device includes a display device such as an LCD, a PDP, or a DLP projector. The authentication result display device also includes an LED and a speaker.

一方、前述した課題を解決するために、本発明では、デジタルAV信号を受信するための受信方法と、ソース機器との間でAV信号出力許可認証を行う認証方法と、前記認証方法により実行された前記認証結果を表示するための表示方法とを含むことで、シンク機器側で認証の成否を判別し、その結果をユーザに認知可能な方法で提示することも特徴である。   On the other hand, in order to solve the above-described problems, the present invention is implemented by a receiving method for receiving a digital AV signal, an authentication method for performing AV signal output permission authentication with a source device, and the authentication method. And a display method for displaying the authentication result, the success or failure of the authentication is determined on the sink device side, and the result is presented in a method recognizable to the user.

前記受信方法はHDMI規格に従っている場合を含む。また、前記認証方法はHDCP規格に従っている場合を含む。更に、前記表示方法はOSDにてLCDやPDP、DLPプロジェクターといったディスプレイ装置に出力する方法を含む。また、前記表示方法は、シンク機器に取り付けられたLEDを点灯させる方法や音声により出力する方法も含む。また、前記表示方法は、認証に失敗した場合のみ前記認証結果を表示する方法も含む。   The reception method includes a case in which the HDMI standard is followed. Further, the authentication method includes a case in which the HDCP standard is followed. Further, the display method includes a method of outputting to a display device such as an LCD, PDP, or DLP projector by OSD. The display method also includes a method of lighting an LED attached to the sink device and a method of outputting by sound. The display method also includes a method of displaying the authentication result only when authentication fails.

本発明のAV受信機は、ソース・シンク間で認証処理を行いその結果をシンク機器で判別しユーザに提示するため、ソース機器が視聴不可メッセージをOSD出力しなかったり、シンク機器にディスプレイ装置がなかったりする場合でも、ユーザは認証の成否を認知できるという利点がある。   Since the AV receiver of the present invention performs authentication processing between the source and the sink and discriminates the result at the sink device and presents it to the user, the source device does not output the view-not-viewable message to the OSD, Even if there is no, there is an advantage that the user can recognize the success or failure of the authentication.

シンク機器側で認証の成否を判別しユーザに認知可能な形式で結果を提示するという目的をもっとも単純に実現した形態を図1に示す。図1のAV信号受信装置は、デジタルインタフェース100、認証装置110、制御装置120、認証結果表示装置130を有する。   FIG. 1 shows a form in which the object of determining success or failure of authentication on the sink device side and presenting the result in a format recognizable to the user is realized most simply. The AV signal receiving apparatus in FIG. 1 includes a digital interface 100, an authentication apparatus 110, a control apparatus 120, and an authentication result display apparatus 130.
