  • Twisted pair communications line system
    Publication number: 20100045864
    Abstract: A transmission system for transmitting analog color video signals wherein a cable comprising multiple twisted pairs is employed, and certain of these pairs are coupled to carry selected color signals as a function of the delay provided by particular twist rates. In certain instances, selected signal delay devices are connected in circuit with certain twisted pairs. By such an arrangement, it has been found that relatively long distances between a computer and a monitor may be spanned by relatively low-cost, twisted pair cable commonly used for telephone communications.
    Type: Application
