NAB 2019: Teradek Unveils the Industry’s First Zero-Delay 4K Wireless Video-Transmission System

Teradek (Booth C5725) has announced the Bolt 4K, defining a whole new category of wireless video systems. The groundbreaking technology, found exclusively inside Bolt 4K, offers 8X the reliability of previous HD models, 1.5X more range, and superior image quality.

Bolt 4K is the first 4K HDR wireless video system providing uncompressed, zero-latency (<1 ms) transmission. Unique to Bolt 4K is interoperability, allowing any model range to transmit and receive from the other (for example, a Bolt 4K 750 is compatible with a Bolt 4K 1500).

Teradek Bolt 4K wireless video system provides interoperability as well as uncompressed, zero-latency transmission of 4K HDR.

Bolt 4K transmits 10-bit, 4:2:2 HDR video at a range of up to 1,500 ft. line-of-sight over the unlicensed 5 GHz band and can multicast to 6 receivers simultaneously. For HDR workflows, Bolt 4K supports the HDR-10, PQ, and HLG standards and can transport extended camera metadata, timecode, and record triggers over the wireless link.

Like Teradek’s existing Bolt devices, Bolt 4K offers the industry’s best protection against prying eyes with AES 256 encryption and RSA 1024 key pairing. Combined, these two technologies ensure nobody can decrypt your wireless feed or connect another receiver to your system without explicit authorization.

To further simplify the use of wireless video on set, Teradek launched a free iOS application to manage and monitor every parameter of Bolt 4K in real time, from the convenience of a smartphone. Simply connect to Bolt 4K via Bluetooth to manage transmitter/receiver pairing, wireless channel selection, and the application of 3D LUTs. The app also offers a real-time quality and range analyzer to determine the best transmission distance for a given area as well as the popular 5GHz spectrum analyzer to detect congestion on specific channels.

Bolt 4K will begin shipping in June priced at $3,990 (Bolt 4K 750) and $7,990 (Bolt 4K 1500). For more information, visit 4k.teradek.com.
