High-Resolution Support
The AXI4-Stream HDMI Input Peripheral is designed to accommodate high-definition video capture and processing, supporting resolutions including 720p, 1080p, and 4K. This versatility is contingent on the HDMI version as well as the system's capabilities, allowing for real-time processing of high-resolution streams.
Key features include:
- Color Formats: The peripheral supports multiple color formatsβRGB, YCbCr, and YCbCr 4:2:2βensuring that incoming data can be appropriately converted into standard formats for efficient processing.
- Audio Data Transmission: Alongside video, the HDMI Input can also handle multi-channel audio, which is crucial for applications requiring video and sound synchronization, such as video conferencing or multimedia playback.
- EDID Handling: Through EDID, the HDMI input detects the capabilities of connected displays, enabling the system to adjust video output to match display specifications.
- HDCP Support: For secure media transfer, the peripheral can support HDCP, ensuring that content protection measures meet the requirements of streaming applications.
These features collectively enhance the AXI4-Stream HDMI Input's utility in high-quality video capture scenarios, making it a vital component in multimedia, automotive, and industrial applications.

The HDMI input peripheral supports various resolutions, including 720p, 1080p, and 4K, depending on the HDMI version and the system capabilities. It can process high-resolution video streams in real-time.
Detailed Explanation
The HDMI input peripheral has the capability to handle different video resolutions. This means it can work with standard resolutions like 720p (which is 1280x720 pixels) and 1080p (which is 1920x1080 pixels), as well as higher resolutions like 4K (which is 3840x2160 pixels). The specific resolutions that can be used depend on the version of HDMI supported by the connected devices and the capabilities of the system that is processing the video. The ability to process these different types of video streams in real-time means that the peripheral can manage high data throughput without lag, ensuring smooth video output.
Examples & Analogies
Think of the HDMI input peripheral like a multi-lane highway. Just as a highway can accommodate cars traveling at different speeds and moving in different lanes, the HDMI input can work with video data coming in at different resolutions, from standard to ultra-high-definition. The wider the highway (or the more advanced the HDMI version), the more cars (or video pixels) it can accommodate at once, allowing for faster and smoother travel.
Real-Time Processing

It can process high-resolution video streams in real-time.
Detailed Explanation
Real-time processing refers to the ability of the HDMI input peripheral to handle video data as it is being captured, without any noticeable delay. This is especially important for applications like live streaming or video conferencing, where delays can interfere with communication. The ability to process high-resolution streams means that users can expect high-quality video with minimal lag. This is achieved by the efficient design of the AXI4-Stream interface that allows data to flow continuously and smoothly from the HDMI receiver through to processing units.
Examples & Analogies
Imagine a pizza delivery service. If the service can prepare and deliver the pizzas hot and fresh (just as the HDMI input processes video smoothly and quickly), customers are happy. However, if there's a long wait time (like lag in video processing), customers become frustrated. Real-time processing ensures the 'delivery' of video data is swift, keeping everything running seamlessly.
