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.

- #15: Image Magnification (IMAG, Vidi-walls)In this scenario a number of video signals are shown on large displays or projected onto screens. The signals may be generated by live cameras, be played from video players or even can be transmissions from someplace else via satellite or internet.For best audience perception the signals need tobe in-sync with each othermatch in color be in the displays native resolutionhave audio in sync with video (displays and projectors can have noticeable video processing delays. The V__pro8 provides -frame syncing-RGB and YUV color correction-Format conversion (e.g. for the satellite feed)Audio delayV__pro8 settings may be controlled via the web-browser interface from any computer or from an mc2 mixing console.
