Moving to IP is allowing broadcasters to explore new working practices and mindsets. Esports has grown from IT disciplines and is moving to broadcast and has the potential to show new methods of working.
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 The mechanical timescale of a legacy medium such as tape or film has been replaced by a logical timescale.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.
IP is delivering unprecedented flexibility and scalability for broadcasters. But there is a price to pay for these benefits, namely, the complexity of the system increases significantly as we add more video and audio over IP.
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.
NDI Version 5 is loaded with highly anticipated new features and unseen capabilities, because it was announced a month ago and hasn’t been released yet.
The DVB (Digital Video Broadcasting) Project has selected three candidate codecs for inclusion in its standards and is conducting tests on each for technical compliance before developing draft specifications.
