AJA: HDMI to HDBaseT
AJA’s HDBaseT line of Mini-Converters offer an easy solution for extending video signals up to 100 meters over CAT5 (or better) cable, utilizing the industry standard HDBaseT protocol. Bi-directional IR and RS- 232 for device control is also supported, making these Mini-Converters ideal in a variety of scenarios including: fixed installation AV, digital signage, live events, post production/network/studio environments and on set.
HDBaseT Compatibility
By conforming to the HDBaseT standard, AJA devices can be integrated with existing devices from other HDBaseT-compliant manufacturers which you might already have in use. This compatibility ensures you don't have to buy additional hardware just to integrate AJA devices.
Mix and Match
The HDBaseT signal is a unified standard, allowing not only conversion to and from HDBaseT but also between HDMI and SDI.
For example, an HB-T-SDI can be used to convert an SDI signal to HDBaseT. At the receiving end, an HB-R-HDMI can be used to turn the HDBaseT signal into HDMI, effectively performing an SDI-to-HDMI conversion without the need for any additional hardware.
AJA Quality - Guaranteed
All AJA Mini-Converters are covered by a 5-year warranty and AJA's advanced replacement policy. If a replacement is necessary, AJA will ship a new unit immediately without the need to send the original unit back first, ensuring you are up and running again as quickly as possible.
