Real-Time Ultra HD(8K/144FPS) Full-Chain Solution

Tencent MPS - Product Team

What is Ultra HD?

UHD, short for Ultra-High Definition, is a video resolution standard. UHD typically includes two specifications: 4K UHD and 8K UHD.

4K UHD: It has a resolution of 3840x2160 pixels, which is four times that of Full HD (1080P, with a resolution of 1920x1080 pixels). 4K UHD is commonly found in televisions, computer monitors, projectors, and some high-end smartphones.

8K UHD: It has a resolution of 7680x4320 pixels, which is four times that of 4K UHD and sixteen times that of Full HD. 8K UHD is primarily used in high-end televisions and professional-grade display devices.

The main advantage of UHD is that it provides extremely high picture clarity and detail, especially when viewed on large-screen devices, offering an outstanding visual experience. However, 4K/8K ultra-high-definition videos greatly enhance resolution and clarity, but also come with extremely high bitrates that present significant challenges to the transmission, processing, and playback of the entire chain.

Introduction to the Solution

Tencent MPS has launched a real-time ultra-high-definition full-chain solution to cater to the real-time processing and distribution needs of users for ultra-high-definition content. The solution is based on Tencent's Top Speed Codec transcoding, ultra-high-definition cross-domain transmission capabilities, and a wealth of global resource nodes.

This solution supports access protocols like SRT, QUIC, and RTP, and can achieve real-time processing and distribution of up to 8K/144FPS ultra-high-definition videos. It also supports real-time processing capabilities such as transcoding, media processing, video AI, time shifting, live video caster, and advertisement insertion. Furthermore, the solution can be flexibly deployed in a hybrid cloud model, combining public and private cloud, to cover a wider range of business scenarios. With its ultra-high-definition low-latency cross-domain transmission and real-time processing capabilities, this solution is an ideal fit for users seeking to process and distribute ultra-high-definition content in real-time.

Advantages of the Solution

1. Ultra HD Transmission and Global Distribution Acceleration

The real-time ultra-high-definition full-link solution supports cross-domain transmission of ultra-high-definition source streams such as SRT/QUIC/RTP protocols, combined with Tencent MPS's global audio and video acceleration distribution node group, quickly covering the world with ultra-high-definition content. The cross-regional audio and video transmission capability provided by the solution has advantages such as high packet loss resistance, low latency, and convenient access. The delay of 100Mbps audio and video data transmission under rtt=100ms can be stably controlled within 400ms.

2. Lower Bitrate and Superior Image Quality

Whether it's H.264, H.265, AV1, or H.266, Tencent has independently developed corresponding encoding cores internally. Compared with the widely used x264/x265/libaom in the industry, there are significant improvements in compression performance, encoding speed, bitrate control, and subjective vision. Encoding formats such as H.265 and AV1, paired with Top Speed Codec transcoding, offer superior bitrate and better image quality at the same resolution. By saving 50% of bandwidth, they enhance subjective image quality and enable real-time processing services for ultra-high-definition videos.

3. Real-time Processing and Seamless Integration

The real-time ultra-high-definition full-link solution can achieve real-time processing of 8K/144FPS video through slice transcoding technology. It supports ultra-high-definition content recording, image quality enhancement, and other media processing capabilities. It can seamlessly integrate with video AI, ad insertion, time shifting, live video caster, and other Cloud Streaming Services's functions.

4. Supports Hybrid Cloud and More Flexible Deployment

The system supports a hybrid deployment model of public cloud transcoding + private cloud distribution. Transcoding resources can be expanded as needed, and private distribution nodes can be set up on the internal network to reduce public network bandwidth. This approach is flexible, stable, and reliable.
