HDMI Alternative Mode标准

HDMI Alternative Mode标准


       HDMI Licensing日前推出了一个全新的HDMI Alternative Mode标准,可让USB-C转HDMI线无需任何额外装置/转换器便可工作,并允许兼容设备将视频信号从USB-C接口直接输出到HDMI显示器当中。这也就是说,配备USB-C接口的智能手机、平板电脑、笔记本电脑、或是其他任意类型的设备都可仅凭一根线缆将视频内容直接输入到HDMI显示器/电视当中。

      Alternative Mode标准允许非USB信号通过USB-C线缆被传输,而除了HDMI之外,其他的Alternative Mode标准还能支持DisplayPort、MHL和Thunderbolt接口。只要使用正确的USB-C线缆,这些标准就能让视频信号与常规USB数据同时被传输。
      除了增加使用上的便携性之外,这项标准的重要意义在体现在另一个方面。虽然大多数人对于HDMI线缆都非常熟悉,但这种线缆目前其实分为3种不同的类型:HDMI Type A是我们最熟悉的全尺寸HDMI接口;HDMI Type C又被叫做mini HDMI,是为小型便携设备设计的小尺寸接口;HDMI Type D又被叫做micro HDMI,它常见于智能手机和数码相机当中,是3种接口中体积最小的。在此之前,从mini或micro HDMI设备连接至大尺寸显示器需要借助于适配器的帮助,但Alternative Mode则会彻底解决这个问题。

MHL3.0支持4K分辨率

索尼新旗舰演示MHL 3.0:轻松搞定4K

You may have already followed the announcement of Sony's Xperia Z2 and Xperia Z2 Tablet, but did you know that they are also the first mobile devices to feature MHL 3.0? For those who haven't caught up, this standard allows 4K video output -- over a bandwidth of 6 Gbps -- from a micro-USB port, while giving back up to 10W of power to keep your phone or tablet juiced up. Better yet, you also get a dedicated 75 Mbps channel for data transfer, as opposed to just 1 Mbps in earlier versions, which is only enough for HID input (like keyboard, touch screen, mouse and even gesture control). It's still snail pace compared to the likes of USB 3.0 and Thunderbolt, but at least you can now transfer files to and from your mobile device over the same cable. Besides, it's possible to achieve a higher transfer rate of up to 600 Mbps using special connectors, such as USB 3.0's 10-pin configuration.

At MWC, Silicon Image demoed MHL 3.0 -- powered by its SiI8620 transmitter chip -- working between an Xperia Z2 and a Sony 4K TV, with the bonus capability of navigating through the phone using the TV's remote. The company also showed off file transfer between a USB drive and a Snapdragon 800 development board over MHL 3.0, though products (likely monitors, set-top boxes and docks) that support this feature won't be out until later this year.

索尼发布了新款旗舰手机Xperia Z2和新款轻薄平板Xperia Z2 Tablet,但你可能不知道的是,它们还是首款支持MHL 3.0标准的移动设备。


MHL 3.0接口标准已经发布半年了,为了在移动设备上抵抗HDMI而做了大幅改进,包括支持2160p/30fps 4K超高清输出、最高10W功率充电、增强的7.1声道环绕音效、改进远程控制协议(RCP)支持键盘/鼠标/触摸屏等外设、接口简化等等。事实上,MHL 3.0并不需要专门的接口,可以和流行的microUSB、USB共存,特别是如果使用USB 3.0 10针特殊接口可以最高达到600Mbps,传输4K毫无压力。MHL 3.0还分配了75Mbps的专用数据传输通道,而不像旧版规范哪样仅仅1Mbps。

Silicon Image日前就首次展示了MHL 3.0的实际工作效果,使用了索尼的Xperia Z2手机和一台4K电视,顺利传输超高清内容的同时,还可以使用遥控器在手机上导航。同时展示的还有在U盘和骁龙800开发平台之间通过MHL 3.0传输文件,不过这个功能要到今年晚些时候才会有产品支持。
