Beijing Television Moves To Full Electronic Field Production With Lawo

Chinese state-owned broadcaster Beijing Television (BTV) has bolstered its remote production capability for sports and music events with the help of German based maker of network, control, audio and video technology for broadcast, live performance and theatrical applications Lawo.

BTV has deployed Lawo IP equipment for Electronic Field Production (EFP). This comprises a third-generation 32-fader mc²56 production console with 288 DSP channels for the main desk, along with a 16 fader mc²36 All-in-One console as a backup, plus five A__mic8 and seven A__digital8 AoIP stageboxes. The two consoles respectively provide 512x512 (mc²36) and 8196x8196 (mc²56) routing capacity with redundant router boards. They also integrate Waves SoundGrid, as well as providing both MADI and IP Ravenna/AES67 compatible interfaces.

BTV’s move to full EFP operation comes just a few months after China Central Television (CCTV) also took a further step towards all-IP production with the instalment of three IP-based Lawo mc² consoles. As with the CCTV project, the system integration at BTV was handled by Lawo’s partner NDT, which in this case was also designed using the typical spine-leaf IP switch network involving two Cisco switches.

BTV has been using Lawo consoles since 2008, partly on the basis of their redundancy in critical environments such as live broadcasts and sports productions, as well as for sound quality. The current installation is the first IP audio mobile system within BTV and second in China, using Lawo mc² series mixing based on Ravenna standards.

CCTV has also been using Lawo mixing consoles since 2008 and its network headquarters in Beijing currently relies on four Lawo mc²66 audio mixing consoles to support its production studios and three news studios.
