The Vela Over-the-Air DVR System is designed to capture an ATSC signal and transcode that content to a proxy format for storage. The system comes with an ATSC Tuner with 8VSB input and is designed to capture the primary and up to three sub channels from within your transmitted signal. The DVR system transcodes those channels into an MP4 file format for storage. Chief Engineers, Station Managers, and Sales Staff can search, retrieve, view, trim, and download those proxy files quickly and easily using a web based interface. Search by entering a date and time or just a program name and voila! you have your clip. Scrub through the clip, set a mark-in and mark-out, and then trim and download just the segment you want. The system comes with 1 year of storage for a single channel application (3 months for 4 channel applications). Options for more storage, more channels, and different interfaces (ASI, IP, etc.) are available.
