Tokai TV begins IP migration

The Japanese broadcaster centralised its network operations centre with Media Link’s video-over-IP technology

Tokai Television Broadcasting has chosen Media Link’s IP media switching solution for IP infrastructure upgrades to the Tokai TV network operations centre (NOC).

After the successful installation and migration of the new IP broadcast system, Tokai TV delivered its first live transmission covering the Nagoya International Women’s Marathon held earlier this month.

Supporting numerous video applications for Tokai TV, Media Links’ IP switching solution is designed to transport and switch 4K/Ultra HD (UHD) 12G/Quad SDI, 3G/HD/SD-SDI and DVB-ASI signals over IP, compliant with SMPTE 2022-1, 2, 5, 6 and 7 standards. These are used in the studio master control, sub-control and video tape recorder (VTR) rooms, as well as for live broadcasts that include media from outside sources.

At the heart of the IP media switching solution lies the combined technology of the Media Links MD 8600 IP video gateway/low-latency SDI to IP media converter and high-density MDX Series IP video switcher/router supporting hundreds of inputs/outputs.

Media Links’ PNT (Perfect Non-Blocking Technology) is provided to “guarantee zero packet loss” within the system. This IP transport and switching solution creates a Layer-2 network infrastructure for compressed and uncompressed broadcast IP content delivery within the NOC of Tokai TV. Fully redundant L2 switching for conventional IT traffic such as file transfers is also built into the same physical network.

John Dale, chairman of Media Links, said: “The promise of IP is an actual reality here at Tokai as we are providing a ‘soft’ migration to a single multi-media service platform, accommodating both conventional and higher video resolutions, along with more efficient media production workflows.

“The result is an overall cost reduction as more media services are consolidated onto a single IP-centric platform while still retaining the look, feel and operation of traditional broadcast environments.”
