01The Challenge

Extending a proven HD workflow into 4K

As Chile’s exclusive free-to-air rights holder for FIFA World Cup 2026, Chilevisión wanted to offer audiences a premium Ultra HD experience — one of the most demanding live production environments in the world.
The challenge was to reach 4K without rebuilding existing infrastructure: transform a live 1080i HD broadcast signal into a dedicated 4K UHD channel, bridging traditional broadcast and cloud environments without compromising on quality, resilience or latency.

What the workflow had to handle

A live 1080i HD-SDI feed from Chilevisión’s facilities
HEVC encoding and secure ground-to-cloud transport
Real-time 4K enhancement by Pixop in AWS cloud infrastructure
Cloud-to-ground delivery to ClaroVTR subscribers

02The Solution

Three capabilities that made it possible

Appear’s X20 anchored a hybrid ground-to-cloud contribution chain, working alongside Pixop and AWS to turn a live HD World Cup feed into a premium 4K channel.

01

Hardware-accelerated SRT transport

The X20 moved video reliably between ground and cloud with low latency, using Appear’s industry-leading hardware-accelerated Secure Reliable Transport into and out of AWS.

Robust ground-to-cloud transport

02

High-density HEVC encoding

Chilevisión’s live 1080i HD-SDI feed was encoded in HEVC for efficient, high-quality contribution — the foundation for a premium 4K experience downstream.

Efficient, high-quality contribution

03

Open hybrid ecosystem

An open approach let the X Platform work seamlessly with Pixop’s cloud AI enhancement and AWS — adding 4K without rebuilding existing broadcast infrastructure.

03 · Delivery

ClaroVTR subscribers

Dedicated 4K UHD channel across Chile

Where Appear sits: two X20 units bookend the cloud — one encodes Chilevisión’s HD feed and carries it to AWS over SRT, the other decodes the enhanced 4K feed back to ground for delivery to ClaroVTR subscribers.

A hybrid ground-to-cloud deployment

At the heart of the contribution chain, Appear deployed its X20 to provide reliable, low-latency transport between ground and cloud. Chilevisión’s live 1080i HD-SDI feed was encoded in HEVC and carried over SRT into AWS, where Pixop’s AI platform performed real-time deinterlacing, restoration and super-resolution upscaling to 4K.
A second X20 then received the enhanced feed cloud-to-ground and decoded it for downstream delivery to ClaroVTR subscribers — extending a proven broadcast workflow into 4K UHD without rebuilding existing infrastructure.
