US Television Station uses Artel’s SMART J2K Encoder to support HD Video-Over-IP

Artel SMART J2K Encoders enabled a Broadcaster to use existing 1-Gig Ethernet Infrastructure to compress four HD-SDI video feeds into a 150 Mb/s per-stream to transport and deliver content to its affiliate.

Synopsis

A TV station in the Eastern U.S. added HD video services, which is needed to deliver to an affiliate over an existing 1-Gigabit Ethernet station-to-affiliate link also used to deliver SDI/ASI streams.

But the station’s engineering team found that it couldn’t move the higher-resolution video over the hybrid network due to the bandwidth limitations.  Using higher-speed links would have been very difficult and an expensive hurdle to overcome.

The station approached Artel seeking alternatives that could leverage as much of this existing infrastructure as possible.



The Picture

The SMART Media Delivery Platform™ is an award-winning Software Defined four-channel auto-sense 3G/HD/SD-SDI-over-IP multi-function gateway with an integrated nonblocking Layer 2/3 switch. 

TR-01 based JPEG2000 for compressed video over IP.



The Success
  • Artel’s SMART J2K encoder was utilized to compress HD video below 1G, while at the same time freeing up additional bandwidth for other video and data transport needs.
  • The Broadcaster had already begun a migration to IP using and had already chosen Artel 1G infrastructure, which included a 70-km fiber to EDFA (optical repeater device) to 70-km fiber link that carried SD video from the station to the affiliate.
  • Rather than invest in building out further network capacity to support HD over IP, the station added Artel’s SMART J2K encoder to resolve the problem.
  • This enabled the customer to leverage the existing connections and compress four HD-SDI video feeds into a 150 Mb/s per-video-stream for transport, bringing transport requirement under 1G, while limiting network delay and dispersion.
  • COVID restrictions prevented vendors from entering the facility, so the engineers at the station configured the SMART platform themselves in less than an hour with minimal remote support from Artel.
  • This customer has evolved from analog video, SDI video, ethernet, and now J2K.
  • The SMART J2K provided an economical solution that supports delivery of HD content to an affiliate station and its viewers while also freeing up bandwidth for data transport.
  • As the station’s network continues to evolve, flexible functionality on the SMART platform will allow for seamless adaptation to new technical requirements.

The Story

When a TV station in the Eastern U.S. planned to add HD video services, the station’s engineering team found that it couldn’t move the higher-resolution video to its affiliate over its existing 1G station-to-affiliate link, an SDI/ASI over fiber and Gigabit Ethernet hybrid network built on Artel base fiber infrastructure. The team tried to solve this issue by using higher-speed links but found that dispersion was both a difficult and expensive hurdle to overcome. To keep costs manageable, the station instead sought out a way to leverage as much of this existing infrastructure as possible to improve bandwidth efficiency.

Solution

The broadcaster had already begun migration to IP using its existing Artel 1G infrastructure, a 70-km fiber to EDFA (optical repeater device) to 70-km fiber link that carried SD video from the station to the affiliate. Rather than invest in building further network capacity to support HD over IP, the station added Artel’s SMART J2K encoder, which not only compresses HD video below 1G but also frees up additional bandwidth for other video and data transport needs.

The Artel SMART J2K encoder allows the broadcaster to leverage its existing Artel 1G infrastructure to compress four HD-SDI video feeds into a 150 Mb/s per video streams for transport. Bringing transport under 1G, the broadcaster has been able to limit network delay and dispersion issuing that result from higher network speeds.

Because of COVID restrictions, which prevented outside vendors from entering the facility in person, engineers at the station configured the SMART platform themselves. In under an hour, and with minimal remote support from Artel, station engineers were able to get the new SMART Platform J2K units running and passing four compressed HD-SDI video feeds over their network.

Result

As broadcast technology has evolved from analog video, SDI video, ethernet, and now J2K, Artel has helped customers transform their networks to meet changing format and bandwidth requirements. Artel’s history with this station goes back 25 years, and over this time Artel has supported the station and its engineering team in adopting new technologies and in maintaining the station’s equipment and network for live on-air event coverage.

In this most recent deployment, Artel provided an economical solution that supports delivery of HD content to an affiliate station and its viewers while also freeing up bandwidth for data transport. Going forward, the station can add or upgrade the functionality of the SMART platform for 4K using the genlock function through simple software download. As the station’s network continues to evolve, flexible functionality on the SMART platform will allow for seamless adaptation to new technical requirements.
