Representing the most http://www.satcomresources.com/solutions/Advanced-Forward-Error-Correction powerful inbound coding option available to the industry, iDirect is the first satellite technology provider to integrate 2D 16-State into its satellite communications platform. 2D 16-State dramatically enhances inbound link performance. Coupled with the introduction of demodulator improvements that also comes with iDX 2.0, 2D 16-State delivers improved efficiencies over Turbo Product Coding (TPC) http://docslide.us/technology/2-d-16-state-forward-error-correction-coding.html and provides existing customers a 10-20% increase in their inbound IP throughput without sacrificing link availability. Service Providers can benefit from increased flexibility and efficiency in network design resulting in better link margins, improved IP throughput and faster acquisition. Better Link Margin 2D 16-State can operate at a lower threshold and utilizes an algorithm superior to TPC, particularly for code rates of 2/3 and lower. This results in additional link margins that can be exploited in several ways: Increases link availability in rain fade conditions⢠Enables cost reductions by allowing smaller block up converters or ⢠antennas to be used Enables higher inbound throughput since the remote can operate ⢠at a higher carrier size Improved IP Throughput Three TDMA payload block sizes are supported with the 2D 16-State codes compared to two for TPC. Previously customers had to choose between 1kbit and 4kbit and typically chose 1kbit to avoid the latency of larger blocks. Because of the fixed TDM
for Generic Forward Error Correction Status of This Memo This document specifies an Internet standards track protocol for https://tools.ietf.org/html/rfc5109 the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This document specifies a payload format for generic Forward error correction Error Correction (FEC) for media data encapsulated in RTP. It is based on the exclusive-or (parity) operation. The payload format described in this document allows end systems to apply protection using various protection lengths and levels, in addition to using various protection group sizes to adapt to different media and forward error correction channel characteristics. It enables complete recovery of the protected packets or partial recovery of the critical parts of the payload depending on the packet loss situation. This scheme is completely compatible with non-FEC-capable hosts, so the receivers in a multicast group that do not implement FEC can still work by simply ignoring the protection data. This specification obsoletes RFC 2733 and RFC 3009. The FEC specified in this document is not backward compatible with RFC 2733 and RFC 3009.
