[itu-sg16] WP2 rapporteur meeting
by Noah Luo 04 Aug '10

04 Aug '10

Dear WP2 experts With SG16 chair, Mr.Naito's approval, WP2 has now formally decided upon the time and place for the next WP2 rapporteur meeting. Unfortunately,due to difficulties(mainly practical reasons like meeting dates conflicts and lack of common availability of SG9 and SG16 experts in time) to secure a collocated meeting with SG9 management, this meeting will be a standalone WP2 meeting. The date will be: 29th November - 3rd December 2010. Thanks to Paul's great efforts and CISCO's generous support, our meeting will be held at RTP(Research Triangle Park ) in North Carolina,USA. Detailed information about this meeting will be provided later on. For delegates from some countries, getting a US visa will take considerable time, so we kindly suggest that experts who are interested in this meeting from these certain countries, contact Mr.Paul Jones as soon as possible if US embassy or consulate in your country requires a letter of invitation for visa application. Also, we got some good advices from our experts that the flights in the US won't be very easy to book for a few days following the thanksgiving holiday week, so it may be a wise action to book your flights as early as possible. Best Regards Noah Luo

Last Friday, the SG16 closing plenary consented draft F.S2STreqs in TD 276/PLEN and H.S2STarch in TD 277/PLEN, but it also decided to continue editorial refinements in 4 weeks time before putting them to Last Call. Your suggestions to the text improvement of these two draft Recommendations are very much welcome and appreciated. Please forward your comments to me <<mailto:chiori.hori@nict.go.jp>chiori.hori(a)nict.go.jp>, hopefully by the end of 24 August (UTC). You can find the two documents at the following place: F.S2STreqs "Functional Requirements for Network-based S2ST" <<http://www.itu.int/md/T09-SG16-100719-TD-PLEN-0276>http://www.itu.int/md/T09-SG16-100719-TD-PLEN-0276> H.S2STarch "Architecture of network-based speech-to-speech translation system" <<http://www.itu.int/md/T09-SG16-100719-TD-PLEN-0277>http://www.itu.int/md/T09-SG16-100719-TD-PLEN-0277> Thank you very much for you kind support.

Re: [itu-sg16] TR: [WP3Aud] FW: Question on G.726
by yusuke hiwasaki 28 Jul '10

28 Jul '10

Dear Mr. Yamamoto, Thank you for reporting your findings on G.726. As an Associate Rapporteur of Q10/16 and Editor of G.191 (STL), I would like to give some feedbacks on this report. Please accept my apologies for this slow response. Firstly, to give you some idea on the narrow-band codecs available in G.7xx series, those codecs usually expects band-pass filtered signal between 300 and 3400 Hz, and are characterized using speech signal (and perhaps modem signal) that lies within that frequency range. This means that extremely low frequency input signal such as 1 and 2 Hz is not expected. For the case of G.726, there is a backward adaptive predictor. I do not have your signal and might be wrong in saying this, but my assumption is that feeding a low-frquency signal puts the codec state in an extreme divergence that results in large amplitude impulses as you report. My suggestion for this would be to have either a band- or high-pass filter that eliminates signal below 300 Hz before the encoding block. An example implementation of such filter is also available in STL. I would be happy to answer any further questions, but I think it is appropriate to discuss it at WP3 audio reflector (wp3audio(a)yahoogroups.com). Best regards, yusuke -- ============ Yusuke Hiwasaki, NTT Cyber Space Labs. hiwasaki.yusuke(a)lab.ntt.co.jp Tel: +81-422-59-4815 (Fax: +81-422-60-7811) BEGIN --- 8< --- CUT HERE --- 8< --- From: itu-sg16-bounces(a)lists.packetizer.com [mailto:itu-sg16-bounces@ lists.packetizer.com] On Behalf Of Yamamoto, Tetsuya Sent: Friday, 16 July 2010 8:46 To: itu-sg16(a)lists.packetizer.com Subject: [itu-sg16] Question on G.726 Dear Q10/16 Experts, Sorry to bother you. We have found unexpected results when using G.726. When particular waveform audio data are input to G.726 encoder, the decoded data from G.726 decoder include large amplitude impulses. We can reproduce the same phenomena at any of 16, 24, 32 or 40kbps bitrate when we put sine wave signal with very low frequency such as 1Hz or 2Hz into G.726 codec. Our codec module is generated from the C source code provided by G.191 software tools as is and the all test sequences provided by G.726 Appendix II are passed with this module. It would be appreciated if anyone could give me some suggestions regarding this matter. Thanks and best regards, Tetsuya Yamamoto Sony Corporation END --- 8< --- CUT HERE --- 8< ---

Dear Mr.Schwarz, Thank you for your quick response. The reference C source code outputs encoded data without packing. I don't think this issue is caused by encapsulation procedure.
