HKJC races ahead with Bolero wireless intercom system
The Hong Kong Jockey Club ( HKJC ) has integrated Riedel Communications ’ Bolero wireless intercom system with its existing Artist digital matrix intercom system to provide communications across two separate HKJC race courses and in the HKJC studio located in Sha Tin .
The Hong Kong Jockey Club ( HKJC ), a sports organisation and Hong Kong ’ s premier horse racing operator , has chosen Riedel Communications ’ Bolero wireless intercom system to streamline communications for its video productions .
Bolero is integrated with Riedel ’ s Artist digital matrix intercom system to provide communications across two separate HKJC race courses and in the HKJC studio located in Sha Tin . Reliable wireless communications are essential for HKJC ’ s live TV productions of horse races , according to Yeung Shui Kin , senior broadcasting services manager at HKJC .
He continued : “ Our production crews located all around the race courses have to able to count on clear , stable and uninterrupted comms from the TV studio . After just two weeks of operation , the performance of Bolero has
Panasonic and Atomos create optimal conditions for low light shooting
Panasonic has released the new GH5S mirrorless camera , which users can combine with the Atomos Ninja Inferno 4K / Ultra HD ( UHD ) monitor / recorder . The Ninja Inferno records up to DCI 4Kp60 10-bit 4:2:2 over HDMI 2.0 directly into production-ready Apple ProRes or Avid DNxHR on SSD drives .
According to the companies , users can now enjoy saturated colours and capture “ sparkling shots ” even when shooting in V-Log format in the dimmest conditions . “ Colours are rich and deep even in super low light and reds are really red . Huge amounts of colour information are retained with 10-bit ,” the companies added .
Using the GH5S with Ninja Inferno also allows users to shoot in the hybrid log-gamma ( HLG ) high dynamic range ( HDR ) standard at DCI 4Kp50 and 60 . The correct metadata tags are added to be displayed on YouTube and HDR screens , while the AtomHDR mode on the Ninja Inferno allows for quick and easy setting of exposure when shooting log or HLG images for HDR or regular Rec . 709 ( an ITU-R Recommendation for HDTV ) shooting .
For demonstration purposes , Atomos has released a video shot using a pre-production GH5S near a London landmark . Shot late at night and only in available light , the video was captured in Panasonic V-Log , with the London buses rendered a deep red , and detail otherwise invisible to the naked eye clearly seen on the statue of Admiral Nelson , according to Atomos .
The crew shot in DCI 4Kp50 with the camera ’ s ISO set at either 3200 or 6400 ISO . Lenses used were a Voigtlander 10.5mm f0.95 , 25mm f0.95 and a Canon 70-200mm f2.8 zoom with a Metabones Speedbooster . These combinations allowed a shutter speed at 100th of a second to be achieved with good exposure at all times .

more than met our expectations by delivering outstanding sound quality from any point on our race courses . Also , Bolero ’ s integration with our Artist frame is a huge plus .”
Founded in 1884 , HKJC provides horse racing , sporting and betting on horse racing and overseas football events . HKJC has initially purchased 12 Bolero backpacks , with plans to add more this year , for communications links between its TV studio in the Sha Tin district and its Happy Valley and Sha Tin race courses .
The Bolero systems first went into service for international races in early December .
Introduced last year , Bolero is an expandable , DECT-based wireless intercom system in the licence-free 1.9GHz frequency range . Riedel ’ s exclusive Advanced DECT Receiver ( ADR ) technology improves RF robustness by reduc- ing sensitivity to multipath RF reflections , enabling HKJC crew members to roam efficiently at either race course without losing audio quality .
Cameron O ’ Neil , director , APAC , Riedel Communications , said : “ HKJC is not only an outstanding provider of global entertainment for horse racing enthusiasts , but also the largest community benefactor in Hong Kong — making significant donations every year to support the community and contribute to the betterment of local people .
“ It gives us great pleasure to provide Bolero , our groundbreaking wireless intercom , for HKJC ’ s race tracks at Sha Tin and Happy Valley , in addition to their TV studio . We are confident that Bolero will provide not just the best possible coverage , but also a great benefit to users through its intuitive and advanced features .”
To provide the most optimal conditions for low light shooting , Panasonic encourages the use of the new GH5S mirrorless camera in combination with the Atomos Ninja Inferno 4K / Ultra HD monitor / recorder .

TSL Products releases new audio monitor
TSL Products ’ MPA1 Mix SDI audio monitor is now available . Part of the company ’ s MPA ( Monitor Plus Audio ) range , the MPA1 Mix SDI is equipped with an audio monitoring tool that enables quick and easy creation of audio monitor mixes comprising of embedded SDI audio , AES and analogue audio sources .
At only 1RU high and 100mm deep , TSL Products recommends the MPA1 Mix SDI for use in confined environments , such as outside broadcast vehicles and lightweight flight packs . Equipped with two 3G / HD / SD-SDI inputs , as well as AES and analogue audio inputs , the MPA1 Mix SDI allows users to simultaneously monitor as many as 16 audio channels of their choosing . Mixes can be created using any of the available audio sources , whether embedded in SDI or presented as AES , analogue or any combination thereof .
Stephen Brownsill , audio product manager at TSL Products , described : “ Up to 16 separate audio mixes can be remotely created and then recalled directly on the front panel of the unit using the MPA1 Mix SDI Web page and even using simple network management protocol ( SNMP ). This allows our customers to address differing applications and achieve more efficient workflows .”
All system parameters can be controlled remotely over an Ethernet network using a built-in Web server , while audio signals , signal status and formats can also be viewed remotely via the Web graphical user interface ( GUI ).

Brownsill continued : “ As with the MPA1 Solo SDI , the MPA1 Mix SDI displays audio level meters and mix configurations on its front-panel display , as well as 3G / HD / SD-SDI video sources .”
An HDMI output provides convenient confidence monitoring of any chosen 3G / HD / SD-SDI video source on any external HDMI monitor , the output of which is also stored as part of the 16 mix states .
