Aware that several French distributors had pulled out of this year's SIEL & SATIS, I chunnelled to Paris on day two of the October 20-22 show with minimal expectations. The small size of the Guide de Visite (20 pages A5) added to my misgivings but the event itself proved respectably large, crowded and buzzing. Nearly 280 companies occupied stands i...

Converting for displays


Behind every great display there’s a great converter. Ever since television started to go digital in studios and post production, the number of digital formats has grown. For a while the television standards bodies got a grip and succeeded in pulling nearly everyone along the ‘SDI’ track; now itself expanded to HD-SDI and 3G-SDI – carrying a multit...

Why choose a broadcast or professional monitor
