ViewCast Niagara 4100

ViewCast Niagara 4100

Slightly larger than the 2100 series, the Niagara 4100 offers many more features including the ability to ingest HD video and digital (AES) audio, which makes this appliance ideal for live sports, news­gathering, or anywhere you need HD webcasting or streaming on the go. A, B, and C buttons on the front panel can activate three different streaming profiles. Using ViewCast’s SimulStream technology, the Niagara 4100 can simultaneously stream different data rates, resolutions, and formats, including MPEG-4, Adobe Flash H.264, Windows Media, and iPhone. Niagara GoStream Surf is similar to the 4100, except it inputs analog video instead of SD-HD/SDI.

Like the 4100, the Niagara 7500 has the ability to ingest SD or HD video and digital audio, and on top of that supports switching on the fly between standard and high-definition sources without having to re-initialize the system. This 2RU appliance features the same type of simple intuitive front-panel controls as above and a small built-in video confidence monitor. Preprocessing features include closed-caption extraction and rendering, de-interlacing, inverse telecine, bitmap overlay, scaling, and cropping. Niagara SCX remote management software is included, and it is preloaded with a software development kit (SDK) that allows you to customize the software to your own workflow.

The Niagara 8224 will capture, encode, stream, and archive audio and video on eight fully independent channels at once. Using the Niagara SCX and SimulStream software, both preconfigured, you are ready to set up, control, and monitor the streaming system. You can create multiple streams in different formats in realtime and customize each with individual sizing and scaling, bitmap overlays, and closed-caption prerendering.

Two independent encoding channels allow you to capture SDI video and encode multiple full-resolution (D1) streams with the Niagara Pro II. Applications for this may be broadcasters, studios, enterprise IT departments, content delivery networks (CDNs), and network service providers. Like most of the other offerings from ViewCast, this will create multiple streams in different formats simultaneously.

ZeeVee Zv series

The last entry in the article may seem a little out of place because of its delivery method, but actually it makes perfect sense. ZeeVee uses coax wiring to distribute HD video in realtime. The ZvPro 280 ingests video resolutions up to 1920x1080 and uses MPEG-2 encoding and RF modulation to deliver the video as a QAM channel onto a display’s existing digital tuner. It even has a built-in spectrum analyzer to look for a vacant channel. Two other models, the ZvBox 170 and ZvBox 250, are less expensive versions that work the same way but offer lower resolutions or slightly different control options.
