新版HDMI v1.4标准将支持立体视频信号传输技术

        负责为高清多媒体接口（HDMI）提供授权的代理机构HDMI Licensing近日宣布该机构将在新版HDMI v1.4标准中加入立体视频信号支持功能。负责标准制订的专家组将在下月召开的标准会议上将向这个标准中加入暂定名为“Top/Bottom”的立体视频信号格式。标准中将为立体视频信号的传输协议进行规定，不过HDMI Licensing组织同时表示标准中暂不会对立体视频广播信号格式作强制性规定，他们以后将会对这部分内容进行补充和修改。

        除了对立体视频信号的传输协议进行规定之外，新规范同时还加入了数据传输功能，为HDMI接口加入了一个专用的100Mbps以太网连接通道。另外还加入了用于传输压缩格式音频信号的 Audio Return信道等等。

        据预计，支持HDMI v1.4标准的设备将于明年1月初召开的CES展会上推出。

原文：HDMI Licensing, the group behind the media interface specification, has announced plans to support 3D content with the upcoming HDMI spec v1.4. The consortium will meet in January to add the "Top/Bottom" 3D format. The group acknowledges the lack of a mandatory 3D broadcast format, leaving the standard open for further additions or modifications.

    HDMI 1.4 establishes protocols for several 3D display technologies including frame, line, or field alternative methods; side by side display, and 2D plus depth methods.

    The new specification also features data as an essential feature, with a dedicated pipe for 100Mbps Ethernet connections. An Audio Return Channel is designed to send compressed sound through intermediary devices, while a proposed micro HDMI connector will support 1080p video for small devices.

    HDMI 1.4-equipped devices are expected to be launched early in January at the 2010 Consumer Electronics Show in Las Vegas.
