SMPTE 2022-6 alternative gains support

Evertz is touting an increase in support for ASPEN, the open non-proprietary protocol that it believes is better suited to IP-based production than the SMPTE 2022-6 standard. Submitted to for publication as a Registered Disclosure Document (RDD 37), ASPEN is used for sending uncompressed Ultra HD/3G/HD/SD over MPEG-2 transport streams (TS).

When combined with SMPTE 302M (Audio over TS) and SMPTE 2038M (Ancillary data over TS), it allows broadcasters to switch uncompressed video and audio over an IP network. Among the new ASPEN supporters is Ross Video. At IBC the two companies have announced they are developing 10GE IP interfaces with ASPEN support for the Acuity production switchers, allowing connection to Evertz’s Software Defined Video Networking (SDVN) high capacity switching cores, the 3080IPX and EXE-VSR.

This interface removes the need for external gateway modules and is said to simplify the installation and signal management in the production environment.

Other ASPEN supporters named by Evertz include: Abekas, ChryonHego, Discovery Communications, Game Creek Video, Hitachi Kokusai Electric Limited, NEP Group, PacketStorm, Ross Video, Sony, Tektronics, Time Warner Cable SportsNet and Vizrt.

According to Evertz director of product marketing Mo Goyal, 2022-6 “has limitations” and “doesn’t provide the flexibility” required in production. 3.C20
