System operation

After the transmitter, the receiver, and their connected devices are powered up, the system is fully operational. If any problems are encountered, ensure all cables are routed and connected properly.

NEnsure that the video source and display selected for the DDC are properly connected to the transmitter/receiver pair, and that the transmitter, the receiver, and the display have power applied before power is applied to the video source. If all other devices are not turned on before the video source, the image may not appear.

Technical Points for Digital Video and Content Protection Encryption

Digital Visual Interface (DVI) is a digital video format that was created by the computer industry in 1999.

High Definition Multimedia Interface (HDMI) is a multimedia format that was created by the consumer video industry in 2003.

The HDMI format is built onto the DVI format, adding digital audio and control while reducing the size of the connector.

The HDMI format is likely to replace the DVI format in the near future.

With passive adapters, the HDMI format is backward compatible with the DVI format.

With Extron adapters and/or cables, the HDMI 201 fully supports either format, regardless of the connector type on the video source and display. See appendix A, "Reference Information," for part numbers.

High-bandwidth Digital Content Protection (HDCP) is an encryption method that protects copyrighted digital entertainment material that uses DVI video.

HDCP is generated by video player hardware, enabled by the video content.

The HDCP key is transmitted with the Display Data Channel (DDC).

The DDC signal line was designed for the DDC’s low data rate; the HDCP key rate is much higher.

Without active buffering, an HDCP key signal can travel only a short distance. The display may properly receive the digital video signal, but not the HDCP key. Without the key, the display cannot decrypt the video signal. Symptoms of undecrypted video may include a flashing black or blue screen or “snow”.

With active buffering, an HDCP key signal can travel as far as other signals to ensure proper decryption.

The HDMI 201 actively buffers the HDCP key.

HDMI 201 Rx specifications

The Extron Electronics HDMI 201 Rx is a versatile and high-performing HDMI receiver designed for professional AV installations. This device is engineered to extend HDMI signals up to 230 feet (70 meters) using a single Cat 6a or better cable, ensuring that high-definition video and audio can be transmitted over long distances without compromising quality.

One of the standout features of the HDMI 201 Rx is its ability to support resolutions up to 4K at 30Hz, along with 1080p video at 60Hz. This makes it an excellent choice for environments where crisp, high-resolution visuals are critical, such as classrooms, conference rooms, and auditoriums. The receiver also supports various audio formats, including LPCM, Dolby Digital, and DTS, ensuring that users receive a comprehensive audio experience.

Another key technology employed in the HDMI 201 Rx is EDID (Extended Display Identification Data) management, which allows the receiver to communicate with connected displays to ensure optimal performance. This feature helps prevent compatibility issues and guarantees that the video output is tailored to the capabilities of the display device.

The HDMI 201 Rx also incorporates a unique feature known as HDBaseT technology, which enables the transfer of HDMI signals, Ethernet, and power over the same cable. This simplifies overall installation, reducing cable clutter and minimizing the number of required components. Additionally, the receiver includes built-in support for Power over Ethernet (PoE), allowing it to be powered through the same cable that carries the data signal, which can be a game-changer for ease of installation.

Integrators will appreciate the compact design and low-profile form factor of the HDMI 201 Rx, which allows for discreet integration into various environments. The unit is equipped with a set of LED indicators that provide real-time feedback on power, link status, and signal presence, helping installers monitor performance and troubleshoot effectively.

In conclusion, the Extron HDMI 201 Rx is a robust solution for extending HDMI signals over long distances while maintaining high-quality video and audio performance. With its support for 4K resolution, EDID management, HDBaseT technology, and PoE capabilities, it meets the demands of modern AV installations, making it a reliable choice for professionals in the industry.
