code. I'm working on a problem where I would need an error correcting code of length at least 5616 bits (and preferably not much longer) that could achieve correct decoding even if 40% error detection and correction of the received word is erroneous. I have looked into some basic coding theory error detection and correction in computer networks textbooks, but I have not found anything that would suit my purpose. Does such a code exist? If it does, what

kind of code is it and can it be efficiently realized? If it doesn't, why not? Any insight to the problem will be much appreciated. Topics Information Theory × 165 Questions 4,021 Followers Follow

If errors are crc error detection not random, that is a different story, but in that case we need a model for the channel (like a bursty channel), as other people are pointing out. Oct 25, 2012 All Answers (12) Stefano Cioni · European Space Agency Dear Kimmo, I would suggest you to look at some Turbo-code families. In particular, the 3GPP2 Turbo code has an input block-length which varies continuously from hundreds of bits up to thousands. (see http://www.stanford.edu/class/ee379b/class_reader/3G_turbocode_interleaver.pdf ) Moreover, there is also the LTE turbo code, which allows several block lengths, and for instance the closest for you is 5632 bits. For some public free software for simulating the Turbo codes, you may have a look into this website: http://www.csee.wvu.edu/~mvalenti/turbo.html . Have fun! Oct 25, 2012 Kimmo Halunen · VTT Technical Research Centre of Finland Thank you for your answer, Stefano. I will look into those turbo codes. I am looking for a code that has the length of the codewords at least 5616 bits and the data or the block length can be much shorter (256 bits or so). Sorry for being ambiguous in the original posting. I am not very familiar with coding theory terminology. Oct 25, 2012 Klaus Huber · Ruhr-Universität Bochum Hi Kimmo Halunen, th

April 27, 2009 1:13 PM Subscribe What mainstream DVD player has the best error correction? I'm totally frustrated that I often cannot play scratched rental DVD's on my existing DVD player (an eight-year old Sony player that cost a fortune at the time). I want to get an affordable new player that can play scratched discs well. I don't need any fancy HD/progressive scan/1080/whatever new features. I'm in South Africa so unfortunately I don't have access to any smaller, more 'boutique' brand players, just mainstream brands. I've scoured Google on this topic, and so far have just come up with a few anecdotal recommendations for Panasonic, Pioneer and JVC. I was really hoping to find a site that rated players on this issue, but no joy after nearly an hour of searching. (Incidentally, a similar question WAS asked here on Metafilter before - but nearly five years ago. Only a few recommendations and of course VERY out of date). posted by worldshift to Technology (8 answers total) 2 users marked this as a favorite The Oppo players are excellent, not sure how mainstream they are by you though.posted by zeoslap at 1:20 PM on April 27, 2009 Looks like these guys have them http://www.audiotweak.co.za/ Review from them http://www.oppodigital.com/press/download/Oppo_981HD_AVSA2008Review.pdfposted by zeoslap at 1:22 PM on April 27, 2009 An editor at Ars Technica claims that the Playstation 3 has a high tolerance for scratched discs. I use a PS3 as my main DVD player (after having used a fairly expensive Philips player for seven years) and I've yet to have a disc skip in it. It's even handled a DVD that skipped in my Mac desktop. I'm not sure whether you consider that affordable, though, and it does have features you say you don't need. But it's probably the case that a player that has features you don't need will also be the best with regard to the features you do need.posted by Prospero at 3:05 PM on April 27, 2009 The best (cheapest) solution might be to rip the DVDs ahead of time with a computer that can do error correction on the rip.
