Dejero Hybrid Encoding Technology for low-latency, live video scenarios

/in /by

Dejero Hybrid Encoding Technology is a highly specialized hybrid architecture designed for low-latency, live video contribution scenarios.

Dejero_HybridEncodingTechnology_workflow_TEVIOS

By utilizing a hybrid approach, Dejero provides the speed and efficiency of hardware as well as the flexibility, adaptability and upgradeability of software. The hardware itself is a fast and efficient encoder with field-upgradeable software. Together, this maximizes video quality by dynamically adapting encoding in real time.

Hybrid Encoding Technology works in tandem with Dejero Smart Blending Technology. They form an integrated system that adapts to real-time feedback about the blended connection’s throughput capacity and latency.

Specific features include:

  • Hardware-based encoder: ensures ultra-low latency, power-efficient encoding
  • Auto-scaler: maximizes resolution to reliably encode & transport
  • Resolution optimizer: incorporates complexity & connection feedback to determine max. resolution (spatial & temporal)
  • I-frame request: reduces required transmission bandwidth by only requesting I-frames when needed
  • Complexity analyzer: offers real-time feedback from the hardware encoder
  • Connection analyzer: offers real-time feedback about the blended connection’s throughput capacity & latency

TAG Announces Support for NDI 5 & SRT

/in /by

TAG Video Systems recently added support for NDI 5, the latest version of Network Device Interface, and SRT, Secure Reliable Transport. These two protocols increase connectivity and signal transport options while opening the door to further collaboration and creativity!

NDI 5

Network Device Interface (NDI) is a realtime low latency IP video network technology that allows users to build IP-based video networks and benefit from uncompressed video IP networks. With NDI 5, connect to a wide range of NDI sources such as cameras, switchers, PCs, phones, and video conferencing applications (i.e. Skype). Also capture the output from PCs in order to add websites, PC UIs and video conference participants as tiles on a TAG mosaic. Additionally, enable NDI as an output format. This creates an inexpensive, low-latency and high-quality connection to display devices.

SRT

Secure Reliable Transport (SRT) is an open-source transport protocol. It allows for robust transmission of high-quality high-bandwidth video signals over public internet, unmanaged networks, and WANs without loss or impairments. SRT assures transport of signals across networks with no loss of quality and minimal latency while providing encryption, protecting content during transit. Thanks to SRT support, acquire signals from distant viewers such as remote workers. SRT is often used in cloud workflows and ground to cloud/cloud to ground links to build live linear cloud workflows.

Finally, when current TAG customers upgrade to the latest version of TAG software, they can enable NDI and SRT at no additional cost.

SAPEC Integrates SRT Protocol to Optimize Streaming Performance

/in /by

The LAGUNA Media Processor (LMP) by SAPEC now includes SRT (Secure Reliable Transport) protocol, optimizing streaming performance over unpredictable networks. Thanks to this SRT open-source protocol, the LAGUNA solutions can now carry out secure, high-quality and low latency video over public IP networks (internet).

SRT is an ideal solution for video transport over public IP networks, reducing the costs from UDP and FEC. Applied at the endpoints of the video link as part of the stream flow, SRT protocol delivers the highest quality and lowest latency video. It adapts to network conditions in real time, compensating for jitter and bandwidth fluctuations due to existing network congestion. Thanks to the SRT’s error recovery mechanism, packet loss is minimized and end-to-end AES security encryption is supported.

With this new feature, the LAGUNA Media Processor offers broadcasters even more possibilities. For example, transport up to 8 HD video signals multiplexed (MPTS) or independently (STPS) with one device (1U) over the public internet in low latency. Plus, store different layouts with the 8 signals configured independently as either encoder or decoder.
