At this time, the control unit 111 controls the first video-transfer unit 114 to use the High-Quality Digital Content Protection (HDCP) 1.4 key specification as the communication key, and controls the second video-transfer unit 115 to protect the content with high-quality digital content (HDCP). The 1.4 key specification is used as the key to communication.
此時，影像處理單元113可將影音接收單元112所接收到的影音訊號進行處理並分流，透過第一影音傳送單元114及第一影音輸出埠117輸出一屬於高畫質數位內容保護(HDCP)1.4金鑰規範之影音訊號至顯示裝置15以進行播放。並且影像處理單元113轉換接收到的影音訊號為一聲音訊號，再將此聲音訊號透過第二影音傳送單元115及第二影音輸出埠118輸出屬於高畫質數位內容保護(HDCP)1.4金鑰規範的聲音訊號至音響裝置17以進行播放。 At this time, the image processing unit 113 can process and split the video signal received by the video receiving unit 112, and output a high quality digital content protection (HDCP) through the first video transmitting unit 114 and the first video output unit 117. The video signal of the 1.4 key specification is sent to the display device 15 for playback. And the image processing unit 113 converts the received video signal into an audio signal, and then outputs the audio signal to the high-definition digital content protection (HDCP) 1.4 key specification through the second video transmission unit 115 and the second audio output unit 118. The sound signal is sent to the audio device 17 for playback.
是以，透過上述揭露書所載的技術，本創作所提出的影音訊 號分配裝置透過設置影像處理單元、第一影音傳送單元及第二影音傳送單元，達成可使用僅具有高畫質數位內容保護(HDCP)1.4金鑰規範的音響裝置播放具有高畫質數位內容保護(HDCP)2.2金鑰規範的聲音訊號，並同時播放具有高畫質數位內容保護(HDCP)2.2金鑰規範之影音訊號的目的。讓已購置高級音響裝置的使用者不需進行音響裝置的升級，即可順利播放具有高畫質數位內容保護(HDCP)2.2金鑰規範之影音訊號。 Therefore, through the technology contained in the above disclosure, the video and audio proposed by this creation By setting the image processing unit, the first video transmission unit, and the second video transmission unit, the number distribution device can realize high-definition digital content protection by using an audio device having only a high-definition digital content protection (HDCP) 1.4 key specification. (HDCP) 2.2 key specification audio signal, and simultaneously play the video signal with high quality digital content protection (HDCP) 2.2 key specification. Users who have purchased advanced audio equipment can smoothly play audio and video signals with high quality digital content protection (HDCP) 2.2 key specification without upgrading the audio equipment.
以上所述僅為本創作之較佳可行實施例，凡依本創作申請專利範圍所做之均等變化與修飾，皆應屬本創作之涵蓋範圍。 The above descriptions are only preferred embodiments of the present invention, and all changes and modifications made in accordance with the scope of the patent application of this creation should be covered by this creation.
