Appear TV Provides Video Delivery Solution to Video Assisted Referee Systems (VAR)

Appear
TV, a leading provider of solutions for video contribution, distribution
and streaming, has deployed low latency contribution links for the Video Assistant
Referee (VAR) system in top football leagues in Europe and Asia, strengthening its position as a preferred vendor for this
application. During broadcasted sporting events, video footage of an
incident is reviewed by the VAR, who then advises the referee on what the video
is showing so that a more accurate, on-the-spot decision can be made. For
football, this typically ranges from scoring plays/goals, penalties, red cards
and mistaken identity, and serves as an added tool to relook at the play or
incident to ensure the correct call was made on the field.

Appear TV’s X20 contribution links are currently
deployed in OB vans, where a single X20 chassis encodes more than 20 signals
with low latency before being encapsulated to IP and sent to the video
operation room (VOR). At the reception site, the X20 system decodes the signals
for further analysis. Some of these signals are then encoded in the same
chassis and sent back to the OB vans.

“We are very proud to be delivering a solution with
unique characteristics that is re-defining video delivery in the contribution
segment,” says Sergio Renteria, Sales Director at Appear TV. “Multi-camera
video alignment, multiple codec and format support, and a rich variety of input
and output interfaces enable our clients to satisfy several requirements, such
as delivery of UHD services and transition to IP workflows, all of which have
an increasing demand in the years to come.”

The X20, part of Appear TV’s X-Series line that
includes the X10 and X20, supports “lightweight” intra-codecs (JPEG2000 &
TICO) as well as AVC and HEVC. Option modules for receiving compressed or uncompressed
video from IP or SDI (Optical and Electrical) are readily available. With
backplane latency of less than 1ms, universal applicability for virtually any
video application is ensured, as is the implementation of both current and
future IP video standards, including VSF-TR03, VSF-TR04 and SMPTE2110.

Appear TV’s X20 is ideal for VAR as it fulfills the
highly demanding requirements for this application. With its unique offering of
channel density and ability to combine encoding and decoding of multiple
contribution formats in the same chassis, the X-Series delivers excellent video
quality in a redundant architecture to ensure the highest availability. The
need for high-quality video with low latency is crucial for the referees to verify
calls made on the field. With the X-Series, content can be sent to the referee
monitors immediately following capture allowing them to make the right call,
and not hold up game play.

Appear’s X-Series line is a high-capacity,
ultra-low latency platform designed to address the latest challenges facing the
distribution and contribution market. In addition to VAR, the X-Series is an
apt platform for all live broadcasted events, especially with the increasing
deployment of ultra-high-speed IP networks within all areas of broadcasting.
