video - How to extract SCTE104 packet from VANC stream -


my task extract scte104 packets out of sdi. of readings i've done, packets should in vanc stream, provided blackmagic sdi card. during run-time, can spot afd + cea708 packets, no scte-104 seen nowhere.

i tried reading scte-104's manual including smpte 2010 - see did + sdid values should for, didn't find either.

thanks help!

smpte 2010 sdid=0x7 did=0x41

"the anc data packet containing ansi/scte 104 data shall located in active line portion of lines in vertical ancillary space. data may located in lines in area second line after line specified switching, defined in smpte rp 168, last line before active video, inclusive."

also smpte 2010 anc in luma (y) channel.

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
