Clear-Com a Sound Influence for Chinese Video-sharing App Douyin

Gathering a mix of celebrities, social media influencers and more than 500 guests in an event space the size of a soccer field presents a range of  communications challenges. Douyin – the Chinese video-sharing and social media app – handled them all smoothly for its annual Blooming Night ceremony, with the help of Clear-Com’s HelixNet digital network partyline and FreeSpeak II digital wireless intercom systems.

Douyin is the Chinese equivalent of TikTok, with both social apps owned by parent company ByteDance. The company’s annual Blooming Night is the biggest date on the Chinese social media company’s calendar. This year’s event was held in January at the Mission Hills H‧Brothers Feng Xiaogang Film Commune in Haikou, a 5000 square meter space.

To ensure the gala’s communications ran smoothly, Douyin engaged live events company Panda Dream Quan Cultural Development Co., Ltd (磐德泉文化发展有限公司, PDQ).

PDQ, which has extensive experience with Clear-Com technologies, configured a system combining the FreeSpeak II and HelixNet systems to streamline communications between the broadcast and live event production teams.

“We faced many challenges in building the comms system for this project,” said Ye Lynn, PDQ’s Project Leader. “The total event space was the size of a soccer field, and the stage was far from the console area. To cover this area properly, we needed to use optical fiber and transceiver splitters for reliable transmission over such a long distance.”

To ensure the stability of the comms gear PDQ deployed 12 FreeSpeak II 2.4GHZ transceivers for the director, camera operators, artists, props, stage manager and executive director, with each group receiving four FSII-BP wireless beltpacks.

The HelixNet partyline system was positioned at the console station with separate channels for audio, video, lighting, special effects, lasers and mechanical all linked by CAT6 cable. Each channel was distributed to the HXII-BP beltpacks which “talked” seamlessly and with low latency to the event directors.

The event used two OB vans, one for 4K video and for audio. Each truck’s team was connected with the on-site crews by the FreeSpeak II and HelixNet systems. FreeSpeak II base equipment installed in the 4K OB Van was linked to each group’s FSII-BP wireless beltpacks. The Audio OB van was equipped with two HKB-2X speaker stations and one HXII-BP beltpack (for audio monitoring), linked with HelixNet HMS-4X for the Main Station, Control Area and Director.

“In addition to the challenge of such a huge space, we had to plan for potential system incompatibility and transmission interference caused by other show equipment,” Lynn said. “As always, the Clear-Com technologies gave us confidence and peace of mind knowing there would be no communication issues on-site. These systems seamlessly integrate with the digital wireless equipment of other suppliers and their transmission functionality ensures freedom from interference. The Clear-Com technologies are irreplaceable at this level.”
