JPEG XS, Unlocking the Full Potential of Low Latency Wireless Video
Introduction:
As video resolutions climb higher, the demand for seamless high-quality video content is exploding. 4K has become the new standard, and 8K is on the horizon, offering a more immersive viewing experience than ever before. However, streaming or transmitting these high resolutions poses significant challenges for wireless networks. Even advanced networks like WiFi 6, WiFi 7, and WiHD/WHDI struggle to meet the bandwidth demands for uncompressed video streams at these resolutions.
This is where JPEG XS steps in. With its ultra-low-latency compression technology, JPEG XS enables wireless networks to handle high-resolution video transmissions while maintaining excellent visual quality and minimal latency. In this article, we’ll explore how WiFi 6, WiFi 7, and other wireless technologies can benefit from JPEG XS for smooth, high-resolution video streaming and transmission.
1. The Bandwidth Challenge of Higher Resolutions
As video resolutions increase, so does the required bandwidth to transmit them. For example, jumping from HD (1920x1080) to 4K (3840x2160) results in four times the number of pixels, which demands four times the bandwidth. Even the latest wireless technologies like WiFi 6 and WiFi 7 face limitations when handling the massive data loads of uncompressed 4K and 8K video streams.
Bandwidth Requirements vs Wireless Capabilities:
- WiFi 6/7: While WiFi 6 can theoretically offers up to 9.6 Gbps and WiFi 7 promises even greater throughput, these speeds are still insufficient for uncompressed True 4K or 8K video streams.
- WiHD/WHDI: These wireless HDMI standards provide up to 10 Gbps, but they too struggle to accommodate uncompressed high-resolution content.
| Resolution & Bit Rate Examples | Uncompressed Bitrate | WiFi-6 /7 (9.6 Gbps*) * max theoretical bitrate | WHDI & WiHD (6Gbps) |
| HD @ 60 fps, 4:2:2, 10 bi t | 2.24 Gbps |  | |
| 4K @ 60 fps, 4:4:4, 10 bit | 14.93 Gbps |  | |
| 8K @60 fps, 4:2:0, 10 bit | 29.86 Gbps | | |
Without a form of compression, even the most advanced wireless networks cannot manage uncompressed 4K or 8K video due to the exponential bandwidth demands. A smart compression solution like JPEG XS is necessary to make these higher resolutions feasible for wireless transmission without sacrificing quality or adding noticeable latency.

To address these bandwidth challenges while maintaining video quality, lightweight compression is essential. JPEG XS offers an ideal solution, providing ultra-low-latency compression that is specifically designed for high-resolution video transmission in real-time applications.
What JPEG XS Brings:
- Less than 1 ms latency: Perfect for real-time applications like gaming, live streaming, or virtual reality.
- Visually lossless quality: Indistinguishable from uncompressed video, both for human and machine vision.
- Low power consumption: Essential for battery-powered devices and efficient wireless communication.
- Cross-platform compatibility: JPEG XS supports a range of devices, including FPGA, ASIC, CPU, and GPU.
JPEG XS enables wireless technologies like WiFi 6, WiFi7 and WiHD/WHDI to overcome bandwidth limitations, allowing them to stream high-resolution content without delays or quality compromises.
| Resolutions & Bit Rate Examples | Uncompressed Bitrates | JPEG XS Bitrate | WiFi 6 / 7 (9.6 Gbps*) * max theoretical bitrate | WHDI & WiHD (10 Gbps) |
| HD @ 60 fps, 4:2:2, 10 bi t | 2.24 Gbps | 125 Mbps - 300 Mbps | | |
| 4K @ 60 fps, 4:4:4, 10 bit | 14.93 Gbps | 500 Mbps - 1.6 Gbps | | |
| 8K @ 60 fps, 4:2:0, 10 bit | 29.86 Gbps | 1.5 Gbps - 2 Gbps | | |
By using JPEG XS compression (with ratios ranging from 4:1 to 20:1), WiFi 6, Wifi 7, WiHD, and future wireless technologies can seamlessly deliver True 4K and 8K video streams with minimal latency and no perceptible loss in video quality.

WiFi 6, WiFi 7, WiHD, and WHDI technologies boast extraordinary throughput and low latency, making them suitable for carrying higher-resolution content. However, without compression, the exponential growth in bandwidth requirements makes streaming uncompressed 4K and 8K impractical. TicoXS, a lightweight implementation of the JPEG XS standard, addresses this by dramatically reducing the bandwidth required for video transmission while preserving near-lossless video quality and maintaining ultra-low latency.
By incorporating TicoXS, wireless technologies can unlock their full potential, offering the best of both worlds: high-resolution video transmission with seamless user experiences, all over constrained bandwidth.
4. Future-Proofing Wireless Video Transmission with TicoXS FIP
TicoXS also brings a new feature called the Flawless Imaging Profile (FIP), which pairs JPEG XS compression with error concealment techniques to ensure reliable wireless AV transmission, even over unpredictable networks like WiFi. This advanced profile allows seamless distribution of 4K and 8K content over both WiFi 6/7 and existing Cat5e Ethernet cables without additional infrastructure costs.
Benefits of TicoXS FIP:
- Cost-efficiency: Transmit 4K and 8K over existing 1 Gbps Ethernet networks (Cat5e cables), eliminating the need for expensive upgrades.
- Error control: Error concealment capabilities make it ideal for wireless transmission in unpredictable environments like WiFi, ensuring a stable and high-quality video experience.
- Sustainability: By compressing video streams, TicoXS enables lower power consumption and reduces the need for bandwidth-heavy infrastructure.
Conclusion:
As 4K and 8K content becomes the norm, wireless networks like WiFi 6, WiFi 7, and WiHD need efficient compression solutions to meet the growing bandwidth demands without sacrificing video quality.
JPEG XS, and particularly our TicoXS and TicoXS FIP Codecs, provide the perfect solution for ultra-low-latency, visually lossless compression, enabling these networks to transmit high-resolution content smoothly and efficiently.
By embracing these new IP cores, manufacturers and service providers can offer flawless video and display transmission experiences over WiFi 6, WiFi 7, and existing Ethernet infrastructure, ensuring seamless performance for high-resolution content with minimal latency.
