Haivision helps ESS to offer multi-lingual commentary

MUMBAI: ESPN Star Sports has adopted Haivision‘s Barracuda H.264 encoder and Makito decoder at its Singapore and Taiwan facilities to support live sports commentary in multiple languages.


The extremely low latency of the Haivision encoder and decoder enables ESS to adopt an exceptionally fast and cost-effective model for delivering quality HD content in which commentary is closely synchronised with the video.


"The remarkably low latency of Haivision‘s Makito and Barracuda systems is critical to our live multilingual commentary model," said ESPN Star Sports vice president of operations and technology Colin Sherriff.


In providing sub-second round-trip latency, the Haivision systems enable us to improve the quality of commentary by using local voiceover talent. We‘ve also been able to eliminate our reliance on costly ISDN links and therefore realize a very quick return on our investment."


Within ESS‘s new video workflow, live HD programming coming into the ESS Singapore facility is down converted to SD and using the Makito/Barracuda systems‘ lowest latency settings, it is sent across an IP link to the Taiwan office.


A commentator in Taiwan then provides a Mandarin voiceover for the live video, which is delivered back to Singapore across the IP link using an audio IP codec.


In Singapore, the voice is inserted into the incoming signal, adding Mandarin commentary prior to routing the video to studios and transmission suites. The latency of the Haivision systems is so low that ESS doesn‘t need to delay the main incoming HD video feed to ensure that the commentary is synchronised with the video.


ESS is expanding its utilisation in Taiwan with a second channel for additional commentary and is in the process of investigating deployments in other countries and regions in the Asia/Pacific region. The Barracuda and Makito high-performance encoder and decoder were delivered by local systems integrator Techtel.
