Early proposals included a Roland production switcher to fix the problem of high latency when switching video sources. However, to reduce cost and increase flexibility, CES is exploring the possibility of building a switching PC with a four-channel video capture card. This would require AdTech to run four video outputs from the DM switcher to the back wall.&lt;/div&gt;</summary>
