Similarly, wide deflection angles are now being adopted in the color picture tube field. Since the principle of the color picture tube is far more complex than that of the black and white tube, a sophisticated production technology is necessary, and consequently production techniques of wide deflection angle color tubes are less advanced at present. Companies producing the conventional 3-gun shadow mask tube recently have successively announced improvement of their mass production technology and have greatly changed the design of the tube itself in their efforts to achieve ease of production comparable to that of the 90°deflection tube. Since their principal objective is to make the picture tube thinner, achievement of picture quality at the same level as in the 90°deflection tube is one of the problems.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1973-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131849707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic add-on signalling technique allows more efficient utilization of the television spectrum. Added information, producing no perceptible interference with either the picture, or ancillary and test signals, is sent through a television channel along with the standard video signal. Novel techniques to significantly reduce errors in the data channel will be described. Several interesting systems utilizing this new signalling method have been built and will be described in this paper.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1973-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133521925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two additional subchannels are broadcast in addition to the monophonic channel and the biphonic subchannel to accommodate the additional audio signals. The first of these additional subchannels uses double sideband suppressed carrier (DSBSC) AM modulation and is broadcast in quadrature with the existing biphonic subchannel at 38 kHz. System 2A, utilizing upper single sideband suppressed carrier (SSBSC) AM, broadcasts the second additional subchannel at 76 kHz while system 3B, utilizing vestigial sideband suppressed carrier (VSBSC) AM, broadcasts the second additional subchannel at 90.25 kHz. Both systems provide the necessary spectrum for the existing SCA subchannel centered nominally around 67 kHz. Standard pre-emphasis is employed to broadcast the four discrete audio signals in the band from 50 Hz to 15 kHz. Both systems broadcast an additional pilot subcarrier (at 76 kHz for system 2A and at 90.25 kHz for system 3B) to provide automatic decoder operation for monophonic, biphonic or quadraphonic signals. Sufficient phase linearity is maintained in the baseband spectrum (50 Hz to 91 kHz for system 2A, 50 Hz to 93 kHz for system 3B) to assure adequate separation between the audio outputs.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1973-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123263138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
