KNME-TV uses Snell & Wilcox MEMPHIS to re-encode

Snell & Wilcox has announced that Albuquerque, NM, -based KNME-TV is the first PBS station to use the company's MEMPHIS HD encoder to enable 24-hour HD broadcasting alongside a new datacasting service. The Snell & Wilcox MEMPHIS system allows KNME-TV to re-encode the 18MB/s HD feed from PBS to a 15.5MB/s signal. This bit rate reduction frees the bandwidth necessary for delivering both HD broadcasts and IP datacasting services over a 19.39MB/s ATSC bit stream.

KNME-TV has installed the MEMPHIS system in its TV studios at the University of New Mexico. The station transmits HD signals to a 120mi radius around Albuquerque, as well as to southern Colorado and Taos, NM. With the ability to re-encode HD signals at a high quality level and lower bit rate, KNME-TV has been able to launch commercial datacasting services such as delivery of DVD-quality movies to members of a subscription service. The Snell & Wilcox MEMPHIS is also used for ingest, DVD authoring, satellite uplink and long-haul transmission to other studios on fiber.

MEMPHIS is an SD/HD MPEG-2 encoder that combines PREFIX compression preprocessing and Ph.C motion estimation technology. MEMPHIS accepts inputs in both SD/HD 1080/720 formats; uncompressed PCM, MP1L2, Dolby E and AC-3 audio; and encoding material at any MPEG-2 profile.

WMUR-TV Says FAA Drone Rules Preclude ENG
The FAA’s current rules and proposed ban on flight over people, requirement of visual line of sight and restriction on nighttime flying, effectively prohibit broadcasters from using UAS for newsgathering. ~ WMUR-TV General Manager Jeff Bartlett
