Talk:1seg

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Was just looking at the English site for the Association for the Promotion of Digital Broadcasting, and they refer to it as "One-Seg" instead of "1seg." What's the opinion on this one?

Tricky one - the katakana name is written in romaji as wan-segu, where wan is pronounced like one. Also the NHK papers on the subject all refer to one-seg in English. However the logo is clearly written as the number 1Seg. It seems they are both being used - although such ambiguity is not great from a marketing perspective! --Tom

Hi, Tom. The Association for the Promotion of Digital Broadcasting (Dpa in short) has changed URL from http://www.d-pa.org/ to http://www.dpa.or.jp/ at the chance of reorganization with DTTv and BS DTv Promotion Asso. within Japan on April 1, 2007, and 1seg section shows 1SEG logo and Katakana ワンセグ as you see http://www.dpa.or.jp/1seg/index2.html . Currently "one Seg" redirect to 1seg seems correct direction in Englisg language edition here. You arose the question on Oct., 26, 2006, I haven't seen URL site on that time, Jan. 3, 2008, now with newly URL no English language site found somehow. Anyway one segment DTT is Japanese proprietary system as of now and Dpa officially showing Logo 1SEG and pronounce "One Seg" for sound only but with written Katakana ワンセグ. If some other country start/implement 1seg system, naming of "One Seg." may or may not common or international naming, and who shall define English naming is a question. As of now Dpa does not define English naming, may be official naming "One seg" of English was withdrawn., they only define Japanese language naming and associated logo.I hope URL come back with English site with definite English naming even not 1SEG DTT begin other countries that many people out of Japan is, I guess, interesting 1SEG system. --Namazu-tron (talk) 00:38, 3 January 2008 (UTC)


Criticism[edit]

Does anyone know the sources of that criticism? Is there any japanese who have used this technology here? It'd be interesting if we had a criticism made by someone who really used the technology. Mateus —The preceding unsigned comment was added by 200.253.206.131 (talk) 15:59, 6 March 2007 (UTC).

I've used it (and own a Sharp Papyrus TC-900). The criticisms are valid. I tried using it both as a passenger in a car and on a train; either way it never was able to hold the signal for more than a few seconds while the vehicle was in motion. Inside a house, it works OK if you have the receiver positioned properly, but then what's the point in watching a low-res signal when you can watch it in HDTV on a big-screen TV? A few cell phones have it, but these models typically are mid-range models which delete other important features (such as GPS or international roaming).

We have three units in our household - two on Hitachi W43HII handsets for the AU ( KDDI ) network and one on a Sharp PDA for the E-mobile network. Yes, there are a lot of problems when in motion but it is slowly improving. More penetration by diversity receivers will help but this requires more expensive chipsets and hence increases unit cost. Mostly gets watched in the car when we are stuck in traffic jams. Interesting that the standard broadcast stereo sub carrier is supported so bilingual programs work ( that is you can listen to a supported program - like NHK evening news and a fair number of movies in English - where the English sound track is transmitted on the stereo sub while Japanese is on the main sound carrier ). The number of handsets becoming available now suggests that One-Seg will soon be close to ubiquitous for phones, just like cameras in the handset. Also it is becoming widespread for PDA's, in dongles for PC's , in portable DVD players and also soem notebook PCs. 195.70.19.76 16:24, 10 July 2007 (UTC)Colin 195.70.19.76 16:24, 10 July 2007 (UTC)

Here in Osaka, it's definitely reached "ubiquitous" status, as far as new cell phones go. I'm due to buy a cell phone soon, so I'll see if these uncited criticisms still hold, and call it "research." :) 125.175.148.151 (talk) 11:48, 2 January 2008 (UTC)

Both in Osaka and here in the Kantou region, practically every other person has a phone with 1Seg. You can see people on trains everywhere watching on their units, even on long trips (not sure about Shinkansen). Perhaps the original critic could update the info, since some time has already passed since he posted it and 1seg has had some real improvements. Punong bisyonaryo (talk) 00:43, 9 October 2008 (UTC)

As of December 2010-January 2011 in Japan, 1seg reception is still hit-and-miss inside houses or within moving vehicles. For all practical purposes, 1seg works no better (or worse) than a pocket ATSC TV does in the US. The difference though is that the pocket ATSC TV has much better resolution... —Preceding unsigned comment added by 206.124.149.116 (talk) 21:28, 5 January 2011 (UTC)

Who would we contact to request this be done in NA as well? —Preceding unsigned comment added by 24.141.81.65 (talk) 19:59, 3 September 2008 (UTC)
