The global demand for video content, highlighted Aws in presenting new instances, has increased rapidly and now counts the largest audiences in Internet traffic and mobile network.

The cases are in the eyes of everyone, daily, as they teach the problems that are having over the top in erotic streaming services.

Over-the-top streaming services like Twitch, explains Aws, continue to record a boom of content creators looking for a live delivery with high image quality.

At the same time, live event broadcasters are increasingly trying to embrace agile cloud infrastructure to reduce costs without sacrificing reliability, and scale efficiently with demand.

This is the context in which Aws’ announcement of the general availability of Amazon EC2 VT1 instances arrives.

These new instances are designed to provide the best performance in relation to the cost of multi-stream video transcoding with resolutions up to 4K UHD.

The VT1 instances, Aws explained, are equipped with Xilinx Alveo U30 multimedia transcoding acceleration cards with H.264/AVC and H.265/HVC accelerated codecs.

Being optimized for this task, Aws points out that these instances provide a low cost transcoding for live video streaming, with a 30% better price for stream than the latest GPU-based EC2 instances and up to 60% for stream than the latest

Customers with their own live broadcast and video streaming pipeline can use VT1 instances to transcode video streams with resolutions up to 4K UHD.

VT1 instances have network interfaces of up to 25 Gbps that can handle multiple IP video streams with low latency and low jitter.

This capacity allows customers who have these needs to rely on a scalable, economical and resilient infrastructure.

EC2 VT1 instances are available in three sizes and the H.264/AVC and H.265/HEVC accelerated codes are integrated into the SoC Xilinx Zynq ZU7EV. Each Xilinx Alveo U30 multimedia transcoding accelerator card contains two SoC Zynqs, Aws explained.

VT1 instances are suitable for transcoding multiple streams per instance. Streams can be processed independently in parallel or mixed mode (picture-in-picture, side-by-side, transitions).

The vCPU cores help implement image processing and audio processing and multiplexing. The Xilinx Alveo U30 card supports simultaneous output of multiple streams at different resolutions (1080p, 720p, 480p and 360p) and in H.264 and H.265.

Each VT1 instance can be configured to produce parallel encoding with different settings, resolutions and bit rates (ABR scale).

For example, a 4K UHD stream can be encoded to 60 frames per second with H.265 for high resolution display. More lower resolutions can be encoded with H.264 for delivery to standard displays.

Amazon EC2 VT1 instances are now available in the AWS US East (N. Virginia), US West (Oregon), Europe (Ireland), Asia Pacific (Tokyo).
