Dolby prepares to get personal at IBC

Making it possible for broadcasters to provide personalised audio services is a focus for Dolby at IBC this year as the company highlights the benefits of AC-4. A new audio compression format for distributing rich media content, AC-4 uses existing workflows and tool chains to make it possible for broadcasters and OTT service providers to offer a new breed of interactive audio services such as personalised sports commentary or dynamics control, multilingual support and adaptive 360- degree audio experiences on any device.

AC-4, which was published as an international standard by the European Telecommunications Standards Institute (ETSI) in April 2014, is a successor to AC-3 and offers the ability to deliver both channel-based and object-based audio.

Dolby Vision will also be on show at IBC. Dolby Vision is designed to help content creators and TV manufacturers to deliver improved brightness, colours and contrast by augmenting the fidelity of Ultra HD and HD video signals for over-the-top online streaming, broadcast and gaming applications. This is achieved by maintaining and reproducing the dynamic range and colour palette of the original content.
