The California State Parks PORTS® Distance Learning Program puts knowledgeable park rangers and knowledge-hungry students together in a virtual experiential environment thanks to the Roland VR-4HD
The students and their teachers may be in a classroom in Fresno or Bakersfield, but thanks to the unique Parks Online 百家乐软件 for Students and Teachers team (PORTS), they can be transported throughout the California State Parks system during a live interactive free virtual field trip. 现在PORTS是由 罗兰专业A/V’s VR-4HD全合一高清AV混音器, making it easier than ever for HD video and audio to be switched, 在PORTS视频会议程序中混合和发送.

“We use chroma key video to make our interpretive rangers in our studios in Anza-Borrego Desert State Park in Borrego Springs and the Seacliff State Park in Santa Cruz look as though they’re in any number of different environments throughout the park, 例如Año Nuevo, an island where elephant seals haul out to fight for the right to breed. 从某种意义上说，我们的护林员确实存在, because the chroma key backgrounds are coming from live video streaming from those locations,布拉德·克雷解释道, PORTS项目经理.
“The students and teachers in each classroom are seeing all of this live, and they can ask questions in real time that can be answered on the spot by our rangers. 如果他们在屏幕上看到想再看一次的东西, we can have the camera pan back live while the ranger answers the questions. We get to do this for thousands of students and teachers every year, most of whom would never get the chance to visit the California State Parks as a part of their K-12 education experience.”
The PORTS program uses any number of video conferencing platforms, 以及所有的PORTS音频, 远程色度键背景位置的视频, 演播室里的直播摄像机, 还有其他各种来源, 现在路由和混合使用罗兰VR-4HD高清AV混音器. “例如, if a teacher in a classroom asks us about a particular aspect of the show, we can pull in audio and video from our YouTube channel that can show and explain things more deeply,Krey解释道. “But what makes this so incredible is than anyone on our staff can manage the A/V. We can mix and match sources on the fly and not need to have a degree in A/V technology to do it correctly every time.”
Roland’s VR-4HD HD AV Mixer is the heart of the California Parks Online 百家乐软件 for Students and Teachers team (PORTS) interactive virtual field trip production studio
The VR-4HD is a complete HD studio in a compact and portable package that replaces several different pieces of complex A/V equipment. 设计时考虑了单人操作, the VR-4HD enables easy switching and mixing of sound and video using advanced video and audio Digital Signal Processing (DSP) along with dedicated hardware controls, 的投篮, 按钮, 触摸屏界面. 它漂亮地集成了一个数字音频混频器, 视频切换器, multi-viewer touch screen and USB video/audio streaming interface into a stand-alone device.
“当我们15年前开始这个项目时,克雷回忆道, “we were using a standard-definition system that at the time was super complicated and sometimes cumbersome, then we had mixers built into the conferencing unit with medium quality results. 今天, 用罗兰VR-4HD, 非常简单, 独立搅拌机的质量是令人难以置信的. It’s made a huge difference in what we can deliver to our students, and Roland has become a great partner in helping us bring this service to schools.”
