Thomas Edwards from FOX Networks is explaining his P4 program that was first shown at the the European Broadcasting Union (EBU) Network Technology Seminar (NTS) 2018, June 19-20, 2018. 

In a testament to the agility of P4-programmable forwarding planes, the live demonstration builds upon what was shown last year showcasing FOX Networks’ use of a Barefoot Tofino-powered switch from STORDIS. Specifically, this year’s demo will highlight how P4 and Tofino enable the forwarding plane to perform packet processing functions to parse SMPTE ST 2110-20 headers and dynamically compose video from output that is switched using Real-time Transport Protocol (RTP) timestamp and video row number. The open-source P4 program implementing this forwarding plane logic is developed by FOX Networks, and the STORDIS BF6064X is a 64-port 100GB bare-metal switch powered by a 6.5Tb/s capacity Tofino ASIC.
