This is one London retailer's colorful way of explaining that the quality of color reception depends on the antenna as well as the set. It has been estimated that the average Canadian interest- ed in color TV has a roof-top antenna that is tive years old or more -- and has probably mever been overhauled, During that time rust has weakened the guy wires, the transmission line from anten- ma to set has deteriorated to the point where replacement is essential, and wind and weather have battered the coroded an- tenna head. Persons in the market for color television should not only get all the facts on conventional home antenna installation, they should seek the latest informa- tion on locally - available cable- antenna systems and rotorized antenna devices. It is generally conceded that cable systems often give the best color reception results while providing a wider choice of channels. Motor - driven rotary anten- nas can be a practical alterna- tive to separate antenna heads aimed at each major station area. In some centres, where reception is from four or more stations scattered around all points of the compass, a ro- tary - type antenna would re- place the four separate anten- na heads required for best re- ception, however, present the viewer with a maximum choice -of a local station, a more distant Canadian station and an Amer- ican station. For ideal color re- ception this still demands three antenna heads at the home un- less the antenna is a rotorized type controlled from inside. Rabbit ears will often pro- vide acceptable color reception from a local station if the in- multi-path or ghost signals. However, rabbit ears are sub- ject to interference -- some- one walking near them can cause a distorted picture. A London retailer - technician who has been dealing in color for almost a decade believes that everything in color televi- sion needs that much more care and better equipment if the viewer is to get good reception. "In technical terms," he said, a "color signal will use almost the full channel width avail- able, whereas a black-white sig- nal is not nearly as wide. The simple' rule is that color de- mands better equipment and | finer adjustments." Video Printing Plan Slated For Trial Here A experimental system that can broadcast printed copy into the home along with standard television programming is ready for on-the-air testing. The system has the potential to bring about a dramatic ad- vance in home _ information services by making it possible to print information of a news- worthy nature right in the liv- ing room or elsewhere in the home, although it will be a few years before an operating sys- tem might be available to the public. To evaluate the technical per- formance of the system under actual operating conditions, an application has been filed with the Federal Communications Commission for permission to make on-the-air tests between New York City and Princeton, N.J., the site of RCA labora- tories, where the system is be- ing developed. ' Most areas in Canada, ing printed copy into a series of electromagnetic signals which are blended at the trans- mitter with those of regular TV programs by means of an elec- tronic "hitchhiking" technique.- The blended signal is broadcast for reception by standard TV home antennas, The signal is fed from the antenna to the printer without affecting home TV reception in any way. Experimental printers cur- rently under evaluation for this application produce the equiva- lent of a page from a standard paperback book every 10 sec- onds.
