Telestream Releases a PRISM Waveform Monitor Software Update


Telestream, the Nevada City, Calif.-based company known for its broadcast media workflow automation, media processing, quality monitoring, and test and measurement products for the production and distribution of video, has brought to market its latest addition to the PRISM family of hybrid IP/SDI waveform monitors.

Version 3.3 adds significant new video format support for post production applications beyond broadcast television, faster switching of IP inputs, Dolby ED2 metadata support, and more to an already extensive collection of IP and SDI measurement tools, the company boasts.

Designed to be used in video engineering, operations, live acquisition, event production, and post production, PRISM offers faster switching of IP inputs, at around ½ second, camera shading operators can make comparisons quickly and efficiently regardless of whether they are working in an IP, SDI, or hybrid facility.

Version 3.3 now supports DCI 4K post production resolutions up to 4096×2160 and refresh rates from 23.98 to 60p for everything from cinematic to broadcast workflows.

The latest version also offers Dolby ED2 metadata decoding which is used for Dolby Atmos and guard band measurement for comprehensive audio monitoring.

Telestream notes that PRISM is a software-defined instrument family. “This unique capability enables users to add new features and capabilities with a simple software upgrade,” the company says. “In general, there is no special hardware needed to enable new features, which allows PRISM units to be easily updated in the field.”

According to a company spokesperson, broadcast television industry executives may be particularly interested in the updates, as the Waveform Monitor and Vectorscope are widely used as test equipment by broadcast engineers to ensure a quality signal is getting from point A to B.

Furthermore, the new PRISM waveform monitors handle the new HDR formats for better color and dynamic range to ensure that stations can maximize the use of the format as they upgrade their signals for ATSC 3.0 and 4K HDR. And, when it comes to IP-video, the audio also travels down the network cable, so these new devices also check that audio, whether it’s Dolby E (stereo or surround), etc. is correctly laid out and present in the feed.

Additional new features:

  • AV Delay Measurement for SDI, ST2022-6 and ST2110-20/30/31 using the AV delay test signal from Telestream Sync Pulse Generator products.
  • Safe Area display with AFD graticule​ allows users to ensure that text, graphics, and important information like weather, headline, and school closure crawls are visible on consumer’s displays irrespective of aspect ratio and production aperture size.
  • Colorized RGB Parade Waveform / Stop display​ for ease of use and quick operation.
  • Larger floating timecode display​ allows timecode to be easily visible no matter how the tiles are configured.
