Previously a basic record/play system using a hard drive was considered. This relied on a table linking time codes in the recording with physical addresses so that the drive would access audio data blocks in the right sequence slightly ahead of when they were needed. In that way a time base corrector could present the samples in an unbroken sequence at the correct sampling rate to a DAC. The mechanical timescale of a legacy medium such as tape or film has been replaced by a logical timescale.
Building optimized systems that scale to meet peak demand delivers broadcast facilities that are orders of magnitude more efficient than their static predecessors. In part 2 of this series, we investigate how this can be achieved.
When composing and lighting scenes, DOP’s usually seek to maximize texture and perspective. The rationale is simple: We live in a world that is unmistakably three-dimensional, so DOPs seeking to faithfully represent the natural world exploit a range of ways to promote the three-dimensional illusion.
Aside from being the first Summer Olympics to be delayed a year due to a pandemic—shifting technical plans and causing strict work-arounds to comply with health restrictions—this year’s live coverage by NBCUniversal (NBCU) is noteworthy for its move to all-IP operations within the International Broadcast Center (IBC) onsite in Tokyo and for its use of the network’s extensive and disparately located resources to make the Games a success.
For many years broadcasters have been working with static systems that are difficult to change and upgrade. This two part series explores the unfolding of a more elastic future based on COTS hardware and flexible licensing.
The launch of new low orbit satellites for global network coverage will have a significant impact on remote live streaming for broadcasters and webcasters. With the likes of Elon Musk’s SpaceX, Amazon’s Kuiper, or one of the other vendors such as Oneweb vying for vertical space, the outlook for remote communications has never looked more open for change.
For all of those audiophiles out there, Comcast (parent to NBCUniversal) will offer the Tokyo Summer Olympic Games in both Dolby Vision HDR and Dolby Atmos immersive audio. Subscribers to the cable giant’s Xfinity TV service—including its X1, Flex and Xfinity Stream app—will have access to the multichannel audio formats while watching NBC Sports’ nightly primetime show, the Opening and Closing ceremonies, and numerous individual sports. Viewers will also be able to customize their viewing experience for the first time via the Comcast Flex aggregation interface.
