Japan's TV Asahi installs dual-streaming solution
JAPAN: Having built a dedicated studio for streaming programmes, Japanese broadcaster TV Asahi has begun using Blackmagic Design Atem 2 M/E Production Studio 4Ks and Studio Camera HDs.
Based in Roppongi, Tokyo, TV Asahi provides news, sports, music, drama and variety show programming to its audience. Its new web streaming studio has been installed with two Atem 2 M/E Production Studio 4Ks, Atem 1 M/E Broadcast Panel, Blackmagic Studio Camera HD, HyperDeck Studio, UltraStudio Express, SDI to HDMI Mini Converters and SmartScope Duo.
‘This studio is for Internet programmes, which means we have very limited budget and space, and only had a short time to build our system for the studio. Therefore, we needed something high quality, compact and affordable – Blackmagic has it all,’ explained Yosuke Kimura, manager, technical department, TV Asahi. ‘We need to provide a different service to paid subscribers and non-paid subscribers, so we use dual switchers for the two different streams. The Atem 1 M/E Broadcast Panel or the Software Control panel can be connected to either switcher so that we can swap depending on the situation and continue our service. For example, we use the first Atem switcher for main switching and use the second one to “cover” what non paid audiences cannot see.
‘The programme out and Aux out from the switcher are sent to four UltraStudio Express devices for capturing, allowing full streaming video for paid subscribers, free version of the streaming video for non paid subscriber and backup for both can be streamed via four computers,’ offered Mr Kimura. ‘We also use the SmartScope Duo for monitoring full streaming video and free version.’
There are five cameras used in the studio, including a Blackmagic Studio Camera HD. Three HyperDeck Studios are used as players for video clips shown during programmes and as recorders. ‘Recorded data will be saved in an archive,’ he continued. ‘We sometimes stream those after live streaming as an on-demand service. Since it’s recorded onto SSD, it allows us to edit and archive the footage more efficiently.
‘We designed the three walls of the studio differently so that we could use this studio with different set designs when we move our equipment. However, the studio itself is very small, so we needed a very wide lens. Blackmagic Studio Camera HD is compatible with the wide lens we wanted use. The camera itself is compact, so it is suitable for use for such small space,’ concluded Mr Kimura. ‘Also, it is not only affordable and compact, but also has great colour correction tool for the camera.’
