Almost Live with 流媒体: Roland Systems VR-50HD All-in-One A/V Mixer

[Note: This sponsored interview was recorded at NAB 2014.]

Roland Systems describes its VR-50HD as an "all-in-one" mixer, and with good reason: not only can it switch and mix four channels of audio and video feeds via 12 on-board inputs, it can mix video feeds in multiple formats, from a range of sources--both digital and analog--and also scale the sources, 添加画中画, 然后输入键, 它还有USB 3功能.0 out for streaming to a range of platorms, and an HD multiview monitor. It allows a single operator to composite four layers of inputs using faders, 按钮, 还有一个相当大的触摸屏.

流媒体 Producer contributing editor 肖恩林 caught up with Roland Systems Sales Engineer Doug Schouten at NAB 2014 for a close-up look at the VR-50HD and a walk-though of its key features for live-switched/mixed production and streaming. Among the elements Schouten highlighted were the unit's flexibility and versatility with different types of inputs, 它易于设置和使用, and the wealth of monitoring and capture-to-switch-to-stream mobile production capabilities it puts in its operator's hands.

“尤其是在企业界,Schouten评论道, "you can get hit with all different kinds of formats, all different kinds of computers and sources, and this takes care of pretty much anything you can hit it with."

尚伟: It’s 肖恩林 here for 流媒体 Producer. 和我一起的是Roland的Doug Schouten, and we’ll be talking about the Roland VR-50HD video switcher. 你能告诉我们些什么吗?

道格: The VR-50HD is the newest product in our VR line. And some of the traits of the VR line are they’re all-in-one, 音频和视频混合, and they also incorporate a USB output for streaming. The USB is really open-ended because you can stream and you can capture to multiple different streaming services.

Some of the main points here are that you have an audio section and a video section. The basic idea is that you're going to take in XLR type or line-level inputs and then you can also mix HDMI and SDI sources that might have audio as well. You have a four-channel video mixer and you actually have four layers of composition. So you can 添加画中画, another picture-in-picture, and a still key. There’s a great big touchscreen built 正确的 in, so you can switch your sources 正确的 on board.

With the USB output, we followed the class-compliant device of USB standard. Without a driver I can use a really wide variety of different services. 我可以用流媒体播放. I can use Skype or GoToMeeting or something like that. And I can even actually capture even to as simple as QuickTime or to software that we offer for free from our website. Mac or PC, it doesn't matter--there's no driver needed. It’s really simple to get up running and have a very mobile production.

尚伟: 从视频切换到网络直播, this is an all-in-one unit that handles the audio and the video as well. It pushes out a USB class-compliant stream for Ustream, 转播画面, Wirecast, 以及这些类型的服务, 正确的?

道格: 是的. 它是开放式的.
