Phabrix QxL series used in Nvidia Rivermax SDK
The QxL rasteriser series from Phabrix, including NMOS analysis tools and the extended ultra high definition (EUHD) option, are being used extensively in the Nvidia Rivermax SDK. The QxL Series has been deployed by Nvidia Rivermax during new product development to ensure compliance with all of the reference standards, including SMPTE ST2110, and to independently validate timing and tool chains.
Nvidia Rivermax makes use of two QxL features that are contained in the latest software release, V4.5, which was announced in March. As well as a suite of AMWA Networked Media Open Specification (NMOS) tools that provide flexibility when integrating with an NMOS controller and related network topology, V4.5 includes an updated NMOS receiver for QxL that offers more detailed information on the state of the NMOS API to assist with the analysis and debugging of NMOS interoperability.
In addition, Nvidia has been utilising a new EUHD option for the QxL series that provides support for analysis and generation of UHD/4K YCbCr/RGB 444 formats in the range 47.95p-60p.
Prinyar Boon, product manager at Phabrix, commented: “The Nvidia Rivermax SDK team has been using our test and measurement technology for a long time, and along the way has given us lots of valuable feedback that has informed subsequent generations of product development. QxL has unique capabilities when it comes to real-time analysis and validation, which help in the development of new tech solutions like Nvidia’s.”
Richard Hastie, senior director enterprise development at Nvidia, said: “There is no other solution on the market that can analyse and test multiple flows – red and blue, RGB 4:4:4, 12-bit uncompressed, SMPTE 2110 – in real time. Real-time analysis is the capability which really distinguishes QxL for us – and it has proven to be invaluable for our Rivermax solutions development at Nvidia.”
