It is difficult for the average layman and even for most engineers to properly set the contrast, brightness and chroma controls for optimum picture quality. Attempts have been made to solve this problem but costs were high and the solution left much to be desired. With the advent of integrated circuits, the solution is in hand. This paper describes a monolithic integrated circuit wherein a single adjustment controls the contrast, chroma amplitude, and brightness level of the TV receiver. This control adjusts both luminance and chrominance amplitude simultaneously. DC restoration of the video signal to black level eliminates need to readjust the brightness control. The unique DC restoration function is performed in the I.C.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"245 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1974-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132746401","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 circuit types, hereafter called \"analog voltage switch\" and \"logic control circuit\", perform the essential functions necessary for channel selection and indication. Circuit partitioning and design were based on voltage breakdown, supply current requirements, circuit complexity, and a desire to package both circuits in 16 pin dual-in-line plastic packages. The logic control circuit consists of an oscillator which drives an up-down counter, logic circuitry which decodes the up-down counter and provides drive signals for the analog switches in an 8 ×2 array, automatic channel setting circuit, and an AFC defeat sound muting output. This circuit accomplishes channel selection by means of remote control or push-type switches. The analog voltage switch transfers the tuning voltage from the tuning potentiometers to the tuner and drives a high voltage indicating device such as a Nixie tube or neon bulb. Each analog voltage switch contains four switches to a common point and are cascadeable so the number of channels can be expanded in multiples of four to any desired number. However, the logic control circuit was designed to control sixteen channels and thus is used in conjunction with four analog voltage switches.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1974-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122349871","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 signal is encoded by a method which minimizes the effect of microscopic non-linearities within the disc surface: luminance and chroma together modulate an FM carrier of relatively high frequency. Radial tracking is achieved by a method which keeps the focused laser beam centered on the recorded track, requires no auxiliary beams and permits unusually high track density. Timing errors, caused by eccentricity and distortion of the disc, are suppressed by an electromechanical servo which is combined with the tracking servo. Improved timing error correction opens up an interesting possibility of simplifying the decoder.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1974-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124506205","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 initial tubes were designed with a 90°deflection angle; since then 114°and 122°deflection tubes have also been developed.
