新版HDMI v1.4標準將支持立體視頻信號傳輸技術(shù)

        負責為高清多媒體接口（HDMI）提供授權的代理機構HDMI Licensing近日宣布該機構將在新版HDMI v1.4標準中加入立體視頻信號支持功能。負責標準制訂的專(zhuān)家組將在下月召開(kāi)的標準會(huì )議上將向這個(gè)標準中加入暫定名為“Top/Bottom”的立體視頻信號格式。標準中將為立體視頻信號的傳輸協(xié)議進(jìn)行規定，不過(guò)HDMI Licensing組織同時(shí)表示標準中暫不會(huì )對立體視頻廣播信號格式作強制性規定，他們以后將會(huì )對這部分內容進(jìn)行補充和修改。

        除了對立體視頻信號的傳輸協(xié)議進(jìn)行規定之外，新規范同時(shí)還加入了數據傳輸功能，為HDMI接口加入了一個(gè)專(zhuān)用的100Mbps以太網(wǎng)連接通道。另外還加入了用于傳輸壓縮格式音頻信號的 Audio Return信道等等。

        據預計，支持HDMI v1.4標準的設備將于明年1月初召開(kāi)的CES展會(huì )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.
