The media block is an important part of any digital cinema system. The media block decrypts and decodes the feature-film (Hollywood) content and delivers it to the projector in a useable format. Media blocks also manage the Key Delivery Messages (KDMs) – the decryption keys used to unlock the feature-film content at show time.
What makes a great media block?
Here are the features to look for in a media block:
Future-proofed – There will be more
High Frame Rate (HFR) and 4K content produced in the future. You want a media block that can handle the bandwidth requirements of these new formats.
Reliability – A media block – especially an integrated media block – should work seamlessly with the digital cinema projector. You need to consider the reliability of your total digital cinema system, not only the projector or media block’s reliability.
DCI compliance – Your media block should be DCI compliant for all content formats and resolutions.
Backed by the right company – Choose a media block vendor that is committed to supporting digital cinema now, and in the future, even after all the digital conversions are done.
