After processed by the audio processor, the new audio content can be encoded to audio stream and merged to original video stream from RX port and then a complete video/audio stream can be transmitted by TX port.
新的音频内容经过音频处理器处理后，可以从RX口编码成音频流并合并到原来的视频流中，然后通过TX口传输完整的视频流/音频流。
In some application, the external audio would like to be transmitted by TX port without HDMI input signals.
在某些应用中，外部音频希望通过TX端口传输，而不需要HDMI输入信号。
An embedded pattern generator in IT66326 could be used to generate internal video stream, which is merged to the external audio stream generated by audio encoder function to form a complete HDMI output signal.
利用IT66326中的嵌入式模式发生器生成内部视频流，并与音频编码器功能生成的外部音频流合并，形成完整的HDMI输出信号。
The IT66326 TX port contains an audio receiver designed for Enhanced Audio Return Channel (eARC) and it is also backward compatible with the HDMI 1.4 Audio Return Channel (ARC).
IT66326 TX端口包含一个专为增强音频返回通道(eARC)设计的音频接收器，它也向后兼容HDMI 1.4音频返回通道(ARC)。
When operating in eARC mode, the Differential Mode Audio Channel (DMAC) bandwidth, i.e. 98.304 Mbps, is allowed to receive 8channel 192K or 8-channel 96K audio from HDMI Sink.
当在eARC模式下工作时，差分模式音频通道(DMAC)带宽，即98.304 Mbps，允许从HDMI Sink接收8通道192K或8通道96K音频。
No video stream and CEC function is required when eARC link is active.
eARC链路激活时，不需要视频流和CEC功能。
The IT66326 also builds in HDCP 1.4/2.3 hardware engines, which can be used to disable the HDCP encryption at the output port or convert HDCP 2.3 to HDCP1.4 for closed system application.
IT66326还内置HDCP 1.4/2.3硬件引擎，可用于在输出端口禁用HDCP加密或将HDCP 2.3转换为HDCP1.4用于封闭系统应用。
Each IT66326 chip comes preprogrammed with a unique HDCP key, in compliance with the HDCP 1.4/2.3 standard so as to provide secure transmission of high-definition content.
每个IT66326芯片都预先编程了一个唯一的HDCP密钥，符合HDCP 1.4/2.3标准，以提供高清内容的安全传输。
Users of the IT66326 need not purchase any HDCP keys or ROMs.
IT66326的用户不需要购买任何HDCP密钥或rom。
The IT66326 also provides a complete solution of Consumer Electronics Control (CEC) function.
