...seamless content transfer via real-time IP links that showcase the powerful new IP-based, real-time interfaces for the company's Kahuna 360 production switcher, IQ Modular range, and Sirius 800 Advanced Hybrid Processing router.
Typical applications for real-time IP transfer of content are professional broadcast contribution (content supplied for onward editing or other processing), studio-to-studio media exchange, in-house signal distribution and routing (material sent for further editing or placed on the final path to the end consumer), and live event coverage. At the 2013 NAB Show, Snell's demo will show how IP links can be used to transfer content in real time over an MPEG-2 transport stream, such as those in widespread use for real-time multimedia content communication. Originating as a 1080 59p feed from the Kahuna 360 multi-format production switcher, the content is encoded into a 200 Mbps video stream using the AVC-Intra 100 video codec. The signal is then passed via a Snell IQGBE80 Ethernet switch to Snell IQ modules that provide IP-to-SDI decoding, down-conversion to 1080 59i to feed a video monitor, an IQ module for logo insertion, and encoding back to SDI for transfer to the Sirius 800 router.
