Video content can be provided to an end user by transmitting video data as a sequence of Internet Protocol (IP) packets over the network. When the network contains a wireless link, packet erasures occur because of occasional deep fades. In order to maintain a sufficient video quality at the end user, video packets must be protected against erasures by means of a suitable form of error control. In this contribution, the authors investigate two types of application layer error control : Forward Error Correction (FEC), and the use of an Automatic Repeat reQuest (ARQ) protocol.
