IP has succeeded in abstracting away the media essence from the underlying transport stream, and in doing so is providing scalable and dynamic solutions that are facilitated through cloud technologies and software.
The global high dynamic range (HDR) market is expected to surpass $126 million by 2030, according to Allied Market Research. The projection shouldn’t come as a shock to media and entertainment (M&E) professionals who have been delivering HDR content for platforms like Netflix, Hulu, Disney+, and others for years. Meanwhile, HDR-capable displays have become standard in most production and post environments and across consumer displays. With these developments, HDR has emerged as the preferred production standard, and with just cause; HDR enhances imagery in ways resolution alone can’t while making for a more dynamic audience experience.
IP is an enabling technology that facilitates the use of data centers and cloud technology to power media workflows. The speed with which COTS (Commercial Off The Shelf) hardware can now process data means video and audio signals can be transcoded, edited, and transferred with speeds that are fast enough for real-time live and file-based workflows.
Compression is almost taken for granted despite its incredible complexity. But it’s worth remembering how compression has developed so we can progress further.
At NAB-2022, Hitachi Kokusai Electric Comark (COMARK) introduced the latest E-Compact “BB3” third generation of air-cooled, solid-state UHF high efficiency DTV transmitter product line. Air-cooled transmitters used exclusively for LPTV and Class A digital stations, but also are gaining in popularity for Single Frequency Network (SFN) applications.
Distributing error free IP media streams is only half the battle when building reliable broadcast infrastructures. SDP files must match their associated IP media essence or downstream equipment will not be able to decode it. In this article we dig deeper into SDP files and media IP streams to understand how to keep broadcast infrastructures dependable.
Founded in 2008 in Boston Mass, Zixi began as a company that targets broadcasters, enterprises, over-the-top video providers, and service providers around the world with a content- and network-aware protocol that dynamically adjusts to varying network conditions and employs error-correction techniques for error-free video streaming over IP networks. The intention is to make it easier and more economical to source, manage and distribute live events and live linear channels securely and at scale.
