NAB 2011: IMT’s RF Central To Roll Out microLite HD Compact COFDM Transmitter

Integrated Microwave Technologies’ (IMT) RF Central will showcase its license-free 5.8 GHz microLite HD Compact COFDM Transmitter at the 2011 NAB Show (Booth C6432).

microLite HD is a compact MPEG-4 COFDM digital transmitter designed for the next-generation of compact cameras featuring full HD/SDI capabilities and has low power consumption. The new 5.8 GHz version does not require a license, and makes this wireless transmitter attractive to independent camera crews, production companies, as well as movie and show producers.

“We are making our award-wining high-definition microLite transmitter available to a broader group of customers, who have a requirement for capturing real-time high-quality video,” says Integrated Microwave Technologies President Stephen Shpock.  “By introducing the 5.8 GHz version, we are now able to deliver a crystal clear video picture, while avoiding interference from other wireless systems.  The license-free frequency minimizes obstruction from other 2.4 GHz devices, such as 801.11 wireless LAN, Bluetooth and cordless phones.”

microLite HD can deliver 250mW from a package of less than six cubic inches and features solid H.264 HD and SD encoding capabilities and operates in the standard 2k DVB-T COFDM mode. The H.264 video encoder supports the main profile of the H.264 standard, providing a 30% bit rate reduction or video quality improvement compared to encoders that only support the H.264 baseline profile.  microLite uses Advanced Encryption Standard (AES) encryption to secure the video transmission, to protect sensitive content and to enforce copyrights.

The transmitter supports video and embedded audio transmission with selectable modulation bandwidths of 6, 7, and 8 MHz and requires little setup.  The microLite may be camera mounted via a hot-shoe or paired with Litepanels camera mounted lighting solutions. microLite has a narrow band COFDM mode that occupies just 1.25 / 2.5 MHz of bandwidth. This efficient spectrum utilization allows the camera operators to transmit the video at a reduced frame rate to significantly longer distances.
