BLACKMAGIC DESIGN ATEM TELEVISION STUDIO

摘要

If you're looking for an inexpensive option for switching HDMI and HD-SDI inputs, BlackMagic Design's ATEM Television Studio, which you can find for less than $945, could be the unit for you. In my simple test project, for example, which involved live streaming of a local concert, the unit was ideal. However, while you get a lot for the price, there's also a lot that you don't get, so you need to assess your short- and midterm requirements before buying this unit. This 1RU unit is 11.75in. tall and 19in. wide, but only about 2in. deep-most of that a much needed heat sync. The ATEM has eight AV input ports, four HDMI and four HD-SDI, though two are shared (ports 3 and 4) and software switchable, so you can only connect six total inputs: There's also AES/EBU audio input, but no analog audio. For monitoring, there are HDMI and HD-SDI multi-view displays, with output connectors for two HD-SDI program streams, an HDMI program stream, and one USB 2.0 output for an H.264 encoded version of the program stream. There are no auxiliary buses.
