Crystal Showing VidTime Technology at 2018 NAB Show

New Crystal technology makes distributed playout possible so broadcasters can easily personalize graphics and replace ads on any video channel distributed via cable, satellite or Over-The-Top.

Crystal will demonstrate its VidTime synchronizing technology in its booth at the 2018 NAB show. The demonstration will take a live linear TV channel streamed over a consumer subscription service that contains no ad break signaling, and redecorate it with accurate SCTE 104/35 ad break markers. Those markers will then be used to replace the original ads with different ads of the same length.

This real-world scenario demonstrates several components of Crystal’s product line. Firstly, Crystal Connect will be used to communicate with the origin playout automation system to extract program information and timing. Schedule event data will be matched to VidTime temporal fingerprints taken at the origin. The fingerprints and event data will be sent out-of-band to the Crystal Metadata Cloud and then delivered to the company's s booth at NAB where it will be used to identify specific video frame synchronization and reestablish timing. Once the timing is reestablished, event data will be used to recreate the payload of the original SCTE markers. Using its own SCTE 104 inserter, the company will put the SCTE messages back into the OTT-sourced HDMI. With complete SCTE markers in place third-party tools will be used to replace ads and display custom graphics.

Accurate countdown times will be displayed to show ad breaks and other video metadata that is only known at the video origination point. All of this information will be available to broadcasters for their own platforms, or to be accessed by broadcaster partners via the Metadata Cloud.

By using out of band messaging, the original ad break messages are faithfully retained, which assures the broadcaster ad replacements, blackouts and rights enforcement can be executed correctly by affiliates.

Beyond ad replacement and personalized graphics, the same VidTime technology can be applied to signal monitoring where it can detect delays, or discrepancies between monitoring points both local and remote. It can also be used to detect and correct lip sync errors, synchronize disaster recovery playout, drive customized workflows and 3rd party applications.
