a very simple text based protocol for streaming. And this simplicity is one of the main reasons for the popularity of the protocol. We propose the use of RTSP along with Real Time http://ieeexplore.ieee.org/iel5/71/22233/01036067.pdf?arnumber=1036067 Protocol (RTP) for Adaptive Forward Error Correction (AFEC) based streaming. The idea is to use the existing semantics of the protocol with minimal overloading to achieve the goal. The use of the RTP is solely to provide a mechanism for the packet sequence number, which is the main requirement to ensure reliability. Since, we will be using existing protocol semantics (overloading the existing semantics), we do not have https://www.researchgate.net/publication/4226833_Adaptive_Forward_Error_Correction_AFEC_based_Streaming_using_RTSP_and_RTP the luxury of using Negative Acknowledgements (NACKs) or information rich packet headers. However, we can add the intelligence in the client/server to interpret the overloaded data and achieve the same results.Do you want to read the rest of this conference paper?Request full-text CitationsCitations4ReferencesReferences30Fast retransmission for multicast IPTV[Show abstract] [Hide abstract] ABSTRACT: Abstract In a IPTV distribution network, broadcast television channels are distributed using multicast stream de- livery. Packet loss occuring during transport will impair the displayed video signal and thus reduces the Quality of Experience. Due to the nature of video compression,techniques a single lost packet can lead to visual impairments lasting for multiple seconds, so packet loss should be kept to a minimum.

(Discuss) Proposed since January 2015. In telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding[1] is a technique used for controlling errors in data transmission over https://en.wikipedia.org/wiki/Forward_error_correction unreliable or noisy communication channels. The central idea is the sender encodes the message in a redundant way by using an error-correcting code (ECC). The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code.[2] The redundancy allows the receiver to detect a limited number of errors that may occur anywhere in forward error the message, and often to correct these errors without retransmission. FEC gives the receiver the ability to correct errors without needing a reverse channel to request retransmission of data, but at the cost of a fixed, higher forward channel bandwidth. FEC is therefore applied in situations where retransmissions are costly or impossible, such as one-way communication links and when transmitting to multiple receivers forward error correction in multicast. FEC information is usually added to mass storage devices to enable recovery of corrupted data, and is widely used in modems. FEC processing in a receiver may be applied to a digital bit stream or in the demodulation of a digitally modulated carrier. For the latter, FEC is an integral part of the initial analog-to-digital conversion in the receiver. The Viterbi decoder implements a soft-decision algorithm to demodulate digital data from an analog signal corrupted by noise. Many FEC coders can also generate a bit-error rate (BER) signal which can be used as feedback to fine-tune the analog receiving electronics. The noisy-channel coding theorem establishes bounds on the theoretical maximum information transfer rate of a channel with some given noise level. Some advanced FEC systems come very close to the theoretical maximum. The maximum fractions of errors or of missing bits that can be corrected is determined by the design of the FEC code, so different forward error correcting codes are suitable for different conditions.
