The document discusses the challenges of integrating audio and video in productions and describes how the Arkona Audio/Video Integration unit addresses these challenges by providing synchronized audio and video processing, format conversion, embedding and de-embedding across 8 SDI and 2 MADI I/O with frame synchronization and delay capabilities. Examples of applications of the unit in broadcast centers, multi-camera productions, and signal quality monitoring are also presented.

Expertise
• most companies have either Video or Audio know-
how, not always both
• people say:
„We always have done it that way.“
However
• Productions must become more efficient
despite growing demands

Audio/Video Integration – Challenges 2
October 11th 2012
Practical Challenges
• Keep Video and Audio in Sync
• Video and (embedded) Audio on one cable but
nearly no equipment can process both
-> heaps of „modular“ Embedders and De-
Embedders needed
• Different Video Formats used in productions
• Monitoring Quality and Alerts
