Sapec demonstrates at Vidtrans 24 (California) full LAGUNA interoperability with RIST protocol

  • The Vidtrans24 conference and exhibition held in Marina del Rey (California, USA) demonstrates SAPEC’s commitment to the RIST (Reliable Internet Stream Transport) standard.
  • The multichannel UHD/HD/SD LAGUNA platform sent a feed from Madrid (Spain) to California demonstrating seamless performance using Public Internet.
  • RIST, as an open and accessible standard, will be incorporated into the Internet transmission protocols supported by SAPEC platforms.

Madrid, March 22, 2024 SAPEC has demonstrated its expertise in the video contribution and distribution area for broadcast by participating in a demanding interoperability test using the RIST protocol. The test took place at the prestigious Vidtrans24 Annual Conference and Exhibition, a global meeting held in Marina del Rey (California, USA).
Vidtrans, the annual conference of the Video Services Forum (VSF), annually brings together service providers, users and manufacturers dedicated to fields such as interoperability and training around network technologies. The 2024 edition featured an extensive program of activities in which topics of special interest for the development of the broadcast industry, such as cloud-based production, the implementation of protocols such as IPMX or RIST, network monitoring or technology applied to the production of live sports, were discussed.
SAPEC, as a company with decades of experience and a growing number of audiovisual content transport platforms deployed worldwide, was invited to be part of this event to demonstrate its ability to manage audiovisual content transported with RIST through a technical demonstration.
Created by the Video Services Forum itself, this protocol designed to transport content over the public Internet has important advantages. First, it is an open and standardized protocol with no proprietary company involved. It also has maximum security encryption systems such as PSK (Pre-Shared Key) or DTLS (Datagram Transport Layer Security) and additional strengths such as bonding capabilities, multicast support and packet correction in case of loss which can reach 45% of the content.
LAGUNA, SAPEC’s first RIST-compliant platform
The solution featured in SAPEC’s interoperability tests was the high-performance UHD/HD/SD multichannel platform LAGUNA, which supports HEVC, H.264 and MPEG-2 standards. Supporting Ultra High Definition workflows, LAGUNA has recently received a wave of new features such as thumbnail display for DUAL, QUAD and OCTAL models; analysis and monitoring functions with the ETR 290 specification; the possibility of using the equipment as gateways, or its compatibility with the MPEG-H immersive audio standard developed by the Fraunhofer Institute.
As part of Vidtrans, a LAGUNA model was used to send a 1080i25 HD signal with H.264 encoding from Madrid (Spain) to California during all the event days. It did so uninterruptedly and without service outages at any time, demonstrating the resilience and adaptability of SAPEC’s solution.
The success of these interoperability tests anticipates the arrival of RIST to LAGUNA, coexisting with other widely demanded protocols such as SRT. Juan José Anaya Luengo, CTO of SAPEC, highly values the Vidtrans experience and anticipates the launch of RIST in LAGUNA: “With the imminent arrival of RIST, SAPEC will expand the range of public IP transport protocols supported by LAGUNA. In this way, SAPEC demonstrates that it is prepared to be completely flexible and adaptable to the current and future needs of its customers and partners.”
SAPEC will be exhibiting at the upcoming NAB Show 2024 in Las Vegas (April 13 – 17), where it will showcase important enhancements to existing products, such as the RIST protocol signal transport over LAGUNA, which has already proven its reliability in highly challenging applications.
