Busby","doi":"10.5594/J13338","DOIUrl":"https://doi.org/10.5594/J13338","url":null,"abstract":"The principles of signal digitization as they relate to digital television are presented in such a way as to lay groundwork for future digital television papers. To clarify the steps that are involved, a hypothetical “manual” conversion of an analog signal to its digital equivalent is examined. For sampling color television signals, the best sampling rate is considered to be exactly three times the color subcarrier frequency. Various methods of digitization are mentioned, and those suitable for wideband signals are defined. Quantization error and the problems of noise and noise measurement are discussed. The great advantage of handling television signals digitally is that digital quantities are capable of being sent, received, switched, stored, recorded and delayed virtually without distortion. Whatever bad effects accrue from conversion to and from the digital mode need accrue only once. Whatever ills can befall a digital signal, short of total loss, they can be made invisible and they do not accumulate.","PeriodicalId":302553,"journal":{"name":"Journal of the SMPTE","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122302902","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 new film, known as Type 986, retains the excellent sharpness and color rendition of Type 985 print film. The universally known processing sequence based on color developer CD2 with 2-amino-5-diethylaminotoluene monohydrochloride as the developing agent is suitable for Type 986. Processing can also be accomplished with a bleach-fix bath at up to 80°F (26.7°C), and when this is done with super-8 film — with either optical or magnetic soundtracks — total processing time is about 12 min. Sensitometric and modulation transfer curves are given.","PeriodicalId":302553,"journal":{"name":"Journal of the SMPTE","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131257096","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}

A special test target printed on standard color positive film is scanned by the television camera under test. The signals at the outputs of the usual red, green and blue amplifier channels of the camera, resulting from scanning three separate color wedges are compared with the signals obtained at the same outputs from scanning a neutral-density step wedge. Experiments demonstrating the validity of this method are described, and the results of the tests together with an evaluation of the accuracy obtained in this manner are presented.","PeriodicalId":302553,"journal":{"name":"Journal of the SMPTE","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123933663","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 requirements which this places on lighting equipment includes high performance, efficiency, light weight, compact size, and ruggedness. The HMI [Hydrargyrum (Mercury), M — Medium arc length, I — iodide] lamp was developed to meet the needs of TV news applications. Their application, however, has been limited by problems encountered due to “dark frames” when ac arc fluctuation and film speed are not synchronized. With the introduction of the 200 W HMI lamp and ballasts which eliminate flicker problems, the HMI lamp is gaining wide acceptance for TV news applications.","PeriodicalId":302553,"journal":{"name":"Journal of the SMPTE","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131317643","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}
