26 AsiaSat makes key appointments Satellite operator AsiaSat has promoted Fred Ho, director of technical operations, to vice-president, technical operations, and Fred Vong, director of engineering, to vice-president, engineering. In his new role, Ho will lead the technical operations team responsible for overseeing the operations of AsiaSat’s satellite fleet, earth stations, teleport and customer network services. For Vong, he will lead AsiaSat’s engineering team in supporting customer activities, from network design to implementation, developing spacecraft programmes, managing spectrum resources of the company, and working with other departments to access and crystalise opportunities from new technologies. Globecomm provides DTH connectivity to the Middle East Globecomm has been awarded a five- year contract by the Broadcasting Board of Governors (BBG) in support of the Middle East Broadcasting Network (MBN). Globecomm will provide satellite transponder, teleport and terrestrial fibre services for transmitting MBN’s Alhurra TV HD and SD video and Radio Sawa audio content to the Middle East and North Africa. Alhurra’s and Radio Sawa’s programming content will be delivered via satellite to more than 58 million direct-to-home (DTH) users, multiple regional MBN rebroadcasting TV and radio affiliates, and BBG/MBN owned- and-operated 24/7 FM radio stations.

Shawn Liew reports. T he 2018 Commonwealth Games, the fifth Commonwealth Games hosted by Australia, was held from April 4-15 on the Gold Coast in Queensland, Australia. As the host nation romped home with the most medal wins, the XXI Commonwealth Games also provided a significant technology footnote: NEP Host Broadcast helped Seven Network, the Game’s Australian rights holder, to transport multiple live HD signals over IP connections between various venues and the International Broadcast Centre (IBC). NEP’s requirements were to send 10 HD-SDI video along with up to eight au- dio channels from multiple remote venues back to the IBC while sending HD-SDI video and audio channels back from the IBC to each of the remote locations. To achieve this, NEP chose a joint solu- tion from Caton Technology and Digistor, which the latter’s managing director, Andrew Mooney, describes to APB: “Our set-up involved the use of multiple Caton Integrated Video Processor (IVP) devices and their proprietary R2TP protocol to ensure reliable real-time delivery of HD signals from the various venues back to the IBC via an IP link.” One of the challenges faced, he iden- tifies, was the need to ensure absolute minimal latency along with a very high PANELLISTS Martin Coleman Executive Director Satellite Interference Reduction Group Amitabh Kumar Director, Corporate Zee Network Shalu Wasu Managing Director Eleven Sports Network At the 2018 Commonwealth Games held in April this year in Australia, multiple Caton Integrated Video Processor (IVP) devices and its proprietary R2TP protocol were used to ensure reliable real-time delivery of HD signals from the various venues back to the International Broadcast Centre via an IP link. In a live IP production environment, the requirements can be dynamic, and preparation is key, advises Andrew Mooney, managing director of Digistor. bitrate (60Mbps) while maintaining adequate buffers for any packet loss, jitter or delay on the IP link. “Luckily, the IVPs are configur- able and we were able to address these requirements,” Mooney relates. “The incoming feeds were being used for live interviews with return video, so latency was particularly important.” For a live broadcast event watched by millions around the world, any delay in the broadcast delivery can throw a real spanner in the works, even as Mooney acknowledges the current limitations of IP links — ‘store- and-forward’ mechanisms and packet disorder issues, which will both result in a longer delay. He continues: “Added to that User Datagram Protocol’s (UDP) nature, a ‘best-effort’ service cannot guarantee the datagram delivery is in order and correct. To minimise the buffer delay and ensure the smooth playback on the receiver end, re-transmission is also not allowed. “With all the barriers, Caton and Digistor worked together to bring signals from the remote venues to the IBC within the extremely strict delay required.” Also lauding the partnership is Gerald Wong, vice-president, Asia- Pacific and Japan, Caton Technology, who highlighted how the companies started their on-site work on the first day the IBC was op
