Tektronix Prism bridges the gap between SDI and IP with its unique ability to correlate SDI and IP media signals.
At the 2016 NAB Show, Tektronix made a number of significant video test equipment business and product announcements relevant to broadcasters and the upcoming Rio Olympics.
Tektronix unveiled Prism, an industry-first hybrid SDI/IP media analysis platform designed to enable a smooth transition from a SDI-based to an IP-based infrastructure.
Prism offers input signals identification that can quickly identify the IP streams in the Ethernet link and the content in each of the streams. Various intuitive displays help shorten the learning curve of users.
It provides packet interval histogram and trend graphs that help determine the root cause of packet loss. Graphical displays coupled with historical data help solve intermittent problems quickly. Its timing display helps engineers quickly adjust the timing of the signal within a hybrid environment using PTP or black burst / tri-level sync as the reference source.
As a software-defined platform, Prism can accommodate a wide range of application needs and will be continuously updated as new technologies and standards emerge.
Tektronix announced several enhancements to its Sentry video quality monitors. The enhancements to Sentry help Broadcasters remain competitive while reducing operational costs. These include full TR 101 290 monitoring and alarming, new RF interfaces and end-to-end closed caption checks to ensure the output meets the latest FCC regulations.
A new adaptive bit rate (ABR) decryption for Sentry ABR delivers real-time QoS, QoE and Perceptual Video Quality (PVQ) monitoring for multiscreen services.
Often known as TV Everywhere or over-the-top (OTT), multiscreen video services use ABR to break content into small fragments of compressed content for transmission to viewing devices. With the increased amount of content delivered via ABR, service providers need the ablity to pinpoint errors in the network quickly to reduce operational expenses related to trouble calls and mean time to detect (MTTD) and repair (MTTR) issues.
With the addition of decryption and decode functionality, Sentry ABR gives users the breadth and depth of monitoring they are used to with linear services. After transcoding in a typical ABR workflow, a video stream is fragmented into fixed time duration fragments, encrypted and Digital Rights Management (DRM) applied. Sentry ABR is now capable of viewing this encrypted content to evaluate the actual viewing experience, or QoE as well as determining PVQ.
New 4K diagnostics
The company announced the industry's first end-to-end HEVC test solutions that provide deep insights into 4K workflows. The MTS4000 provides comprehensive transport streams analysis and interoperability testing. Its deep analysis of the transport streams, PES, and elementary streams helps track down sources of picture anomalies and identify transport streams with syntax errors.
The new extensions to the MTS4000 and MTS4SAV3 test platforms, including comprehensive HEVC analysis tools and a closed caption analyzer for ensuring FCC compliance, allow operators to transition to 4K at their convenience with minimal impact to workflow, infrastructure, staff and budget.
MTS4SAV3 includes a closed-caption analysis-only version of the more comprehensive MTS4EAV7 software and provides a more cost-effective solution for broadcasters primarily interested in verifying FCC compliance.
Rio Olympic support
NBC Olympics, a division of the NBC Sports Group, announced its selection of Tektronix to provide audio and video test and quality monitoring equipment for its production of the upcoming Rio Olympic Games.
Tektronix waveform monitors and rasterizers will be used for quality monitoring and compliance checking during content distribution and broadcast transmission, and for quality control in content production and post-production. The units will also be used for equipment qualification and troubleshooting during installation and maintenance of the facilities at the Games.
The Sentry Video Quality Monitors will provide NBC real-time Quality of Experience monitoring of its coverage of the Games, and to ensure the quality of the video transport back to the United States.
The Tektronix SPG8000A Master Sync and Master Clock Reference Generators will be used by NBC Olympics to ensure stable and reliable timing at the Games.
