Two significant developments within TVU Networks’ transmission technology will be a key part of the company’s CABSAT 2022 exhibition in Dubai. TVU has adapted its TVU G-Link platform to now support low-latency, 8K IP video transmission over commodity internet connections, and new to the TVU Remote Production System (RPS) family is the TVU RPS Link Encoder which allows multi-channel REMI production over cellular networks.
TVU G-Link is a powerful, point-to-point IP video transmission platform designed to provide high-quality, low-latency video over commodity internet connections. G-Link utilizes TVU’s renowned IS+ protocol, link aggregation, and HEVC VBR encoding to produce a stable transmission – even under harsh network conditions. While the TVU G-Link family already supports up to 10-bit 4k 50/60p, TVU has been able to quickly adapt the platform to support 8k 50/60p transmission.
“The flexibility of our IS+ protocol and modular design that forms the basis of TVU G-Link made it easy to adapt the platform to support 8K encoding/decoding,” says Rafael Castillo, Vice President/General Manager, EMEA and Latin America, TVU Networks. “We are starting to see increased demand for 8K acquisition over IP for sports and event broadcasts.”
The TVU G-Link platform uses the HEVC codec to encode at bit rates up to 300Mb/s with sub-second latency over the normal internet. It also features VBR encoding for transmission stability on variable bandwidth connections and can transmit an 8K signal at as low as 60Mb/s.
Another multi-camera transmission breakthrough from TVU Networks is the TVU RPS line of multi-channel REMI solutions. Being showcased at CABSAT is the TVU RPS Link Encoder. The TVU RPS Link Encoder provides multi-camera, synchronized remote production capability (up to 1080p) using IS+ aggregating up to 12 connections, including embedded 5G/LTE modems, WIFI, ethernet or satellite. Ideal for use in remote locations where reliable wired IP connections are unavailable or inadequate, the TVU RPS Link Encoder features a 2RU chassis configurable for up to six 5G modems with external, high-gain antennas. RPS Link Encoder comes in both four-channel and six-channel models with up to two channels of return video.
The TVU RPS Link Encoder is compatible with the existing TVU RPS hardware decoder as well as TVU’s complete Cloud Production ecosystem, including the TVU Producer live production platform, TVU Partyline video collaboration tool and TVU Command Center for centralized signal monitoring. All RPS transmissions in the Cloud can be controlled and monitored using its built-in encoder web interface or via the TVU Command Center.
