This paper describes how File Delivery over Unidirectional Transport (FLUTE) and Dynamic Adaptive Streaming over HTTP (DASH) can be used together to provide mobile video streaming services over broadcast wireless networks. FLUTE is a multicast protocol for multimedia file download; in this proposal, it is adapted to provide video streaming in crowded environments so that video is delivered in a single connection to all viewers, reducing network traffic. FLUTE incorporates an application-layer forward error correction (AL-FEC) mechanism to improve the reliability of broadcast communication. For streaming applications, AL-FEC improves the relationship between peak signal-to-noise ratio (PSNR) of received video and the bandwidth allocated to the connection. The proposal applies simple unequal error protection schemes to favour the download of key frames. Furthermore, since the proposal is based on the same video segmentation as DASH, clients can connect to a DASH repository to repair errors in segments. This paper shows that FLUTE and DASH can be seamlessly integrated into a hybrid broadcast/unicast streaming technology, providing flexibility to trade off PSNR and bandwidth depending on network conditions.
