This will likely be used for the packet stage, Because the encapsulated video bitstream is usually only made to tolerate minimal levels of bit or burst faults, as opposed to the loss of entire packets.

For live video, a re-despatched packet would get there properly following the arrival of the next body of video.
In just the safety goods market, IP-primarily based Shut Circuit Television (CCTV) has made gains about the analog industry. Important components of IP-centered CCTV continue to be in line with analog systems: picture seize, with a mix of IP-based cameras or analog cameras applying IP-based mostly encoders; image transmission; Storage and Retrieval, which works by using technologies for instance RAID arrays and iSCSI for recorded and indexed video; and video management, which affords Website browser-enabled administration and control of IP-based CCTV programs.
