The 
                  Video Revolution
      How the Idiot 
        Box grew up
      (editor's note: 
        this article was updated in May 1999)
      If you're a 
        typical baby boomer - or younger - you grew up with TV. Where the second 
        world war generation and its parents' families used to cluster around 
        the radio, listening to the latest serial, variety, or comedy show, boomers 
        were given visuals with the same shows, and thus spared the awful task 
        of having to use their imaginations.
      The early TV 
        shows, in the so-called "Golden Age," were more or less radio 
        programs with pictures. The obvious link with the Hollywood studios was 
        fought bitterly by those same studios, who thought people who stayed in 
        front of the boob tube wouldn't go to the movie houses. They were dead 
        wrong, of course, but at the time they looked at TV as unwanted competition 
        rather than an incredible marketing opportunity.
      But Hollywood 
        can smell a buck with the best of 'em, otherwise we would never have been 
        subjected to movies like "I Spit on your Grave." But TV was 
        still a little box in the living room, while movies were a larger 
        than life experience that, due to Hollywood's desire to offer something 
        different from the TV experience, gave you widescreen action and sometimes 
        even stereo sound. Oh, yeah, and for the most part, movies gave you colour, 
        while TV didn't (and even when it did it wasn't very good).
      Clearly, if 
        you wanted to slum, you stayed home with TV, while movies were, well, 
        "That's entertainment," (to rip off a phrase from MGM).
      And that's pretty 
        much how it stayed until the latter half of the 1970's, when Sony had 
        the unmitigated gall to introduce something called "the Betamax." 
        It was this machine that began the video revolution, and we should all 
        bow down 
        in gratitude to Sony Corporation.
      Why? Because 
        with the VCR, viewers were freed from the tyranny of the broadcasters. 
        No longer were we forced to watch what they wanted us to see when they 
        wanted us to see it. Suddenly, we could record a TV program and watch 
        it when it was convenient for us. Better still, you could 
        record one show while you watched another! After all, it seemed then (as 
        now) that on the rare occasions when there was actually a good show on, 
        (the exception to the rule of TV being a 'vast wasteland') there'd be 
        two on different channels simultaneously, and you'd have to choose between 
        them. "Sweeps Months" are a perfect example of this: when networks 
        pull out all the stops to offer their best, they all do it at the same 
        time.
      Most families 
        now own at least one VCR and, if you've managed to figure out how to program 
        it, you can set your own viewing habits. You can record a show, rent a 
        movie, or play back something you shot yourself with your camcorder or 
        digital camera.
      This freedom 
        of choice is great. Just think about the World Wide Web around you and 
        the cornucopia of tidbits it offers!
      The Cassette 
        Seen 'Round the World
      It was the VCR 
        that was ultimately responsible for the video revolution. Look at it this 
        way; before you could watch movies on tape (or disc, the first generations 
        of which were introduced within a couple of years of consumer VCR's - 
        thus confusing the marketplace and unfortunately relegating the disc format 
        to the background until the advent of the remarkable DVD) 
        there was little reason to expect more from your TV than a tinny little 
        speaker and a colour picture that, while better than black and white, 
        was a far cry from what's available on today's cheapest sets.
      Once moviegoers 
        decided to stay home, however, they wanted to recreate the theatre experience 
        as best they could. This led to a few pioneering videophiles plugging 
        the "audio out" jack on their VCR into the "tape in" 
        jacks on their stereo. The result was still crummy, mono sound, but it 
        was a vast improvement over what the TV's chintzy little audio amplifier 
        and speaker could put out.
      Then along came 
        stereo VCR's and, while the sound quality didn't improve much (except 
        that you got two channels of crummy audio instead of one), you were one 
        step closer to the real theatrical experience. Hi-Fi (first introduced 
        on beta VCR's and followed swiftly by VHS) raised the audio ante substantially, 
        and is still used today.
      Good thing, 
        too, because by the time Hi-Fi came out most movies were being released 
        to theaters in high quality stereo or in a new beast called Dolby Surround 
        and the video generation was demanding better sound from their expensive 
        VCR's.
      Stereo/Hi-fi 
        VCR's automatically gave you the Dolby surround information that was being 
        encoded on the tapes, so it only made sense that consumer should be able 
        to buy Dolby surround decoders for their homes. This wish came true via 
        standalone, add-on "black boxes" that, while crude by today's 
        standards, finally gave fledgling home theatres the rear channel effects 
        that made people's mouths drop when 'Star Wars' and its successors and 
        imitators played the movie houses.
      Inevitably, 
        the Dolby surround decoder found its way into conventional audio components 
        like receivers, which by that time were adding video switching capabilities 
        (not a big deal, just an extra couple of circuits and buttons for the 
        most part) to increase sales in an audio market that was quickly being 
        overshadowed by the public's fascination with video. Dolby Pro-Logic (which 
        added the vital centre front dialogue channel) then hit the home scene, 
        and home theatre sound potential reached the level of the movie theatre. 
       
      Now we have 
        Lucasfilm's THX sound and the latest DVD's come with Dolby Surround AC-3 
        Digital and/or DTS audio, which take Dolby Pro-Logic to the next technological 
        level and match what's available in theatres.
      Now, if only 
        you could make your TV picture match a movie theatre's
 
      
      TV Grows Up
      Well, electronics 
        manufacturers can smell a buck with the best of 'em, too, and they heard 
        the plaintive cries for "MORE PICTURE;" so TV's started getting 
        bigger, better, and positively bristling with features. Direct view TV's, 
        the normal type of set with which we all grew up, have evolved from a 
        maximum screen size of 26 inches diagonally to 40 inches, with corresponding 
        quantum leaps in picture quality. Meanwhile, projection TV's have evolved 
        from 50 inch "front projectors" (where the 'guns' are in front 
        of the screen like a movie projector - the early models used a swing-out 
        mirror to bounce the image onto the screen) to 61 inch "rear projectors" 
        (self-contained units like a gigantic wall unit, with the screen on the 
        front).
      We should also 
        mention the LCD (liquid crystal display) front projection TV's, which 
        show a lot of promise. In our opinion, however, they're quickly becoming 
        rivals for your TV dollars; earlier models, because of the way they work, 
        looked as if you're watching through a screen door. They're getting better 
        and more competitive all the time, though.
       LCD TV's also 
        work very well as small screens (4 inches or so diagonally), as camcorder 
        viewfinders, and even as the monitor for portable DVD players.
      Today, the home 
        theatre market is dominated by 27 inch and larger direct view, and 46 
        inch and larger rear projection TV's. All of these have gotten remarkably 
        better over the years, but none so much as the rear projection set.
      Rear projection 
        TV's used to be bulky and dim. Now they're quite slim and have pictures 
        that rival their direct view brethren (though they're still not quite 
        as good). The tradeoff between screen size and picture quality is getting 
        less noticeable with each model year and that's great.
      Bells and Whistles
      Digital special 
        effects started cropping up on TV's and VCR's in the late 1980's, the 
        most popular of which has been PIP (picture in picture, a small, secondary 
        screen inside your main one). PIP is okay, and can be useful if you want 
        to keep track of one program (or a tape) while you're watching another. 
        It's most useful, however, if the TV (or VCR) comes with two tuners built 
        in. Otherwise, you need to have two video components (like a TV and VCR) 
        to use it.
      Of course, they 
        don't often tell you that in the store
      TV sound has 
        also improved by leaps and bounds, though in our opinion if you want to 
        do it right, don't worry about your TV's audio: get a good audio system 
        and use it.
      Hughes' SRS 
        (Sound Retrieval System) is offered on TV's from competing brands. It, 
        and a couple of other audio gadgets, claims to give you a surround sound 
        effect from only the two speakers on the TV. It works okay, but it's hardly 
        a substitute for Dolby Surround.
      Some TV's build 
        in Dolby Surround, and/or other audio surround effects (like stadium, 
        theatre, etc.) and some even come with the rear, surround speakers. This 
        is great for one-stop shopping (or if you're living in a place where you 
        can't crank the volume) but again, for a serious home theatre, get a separate 
        audio system and hook 'em all together.
      We've also seen 
        widescreen TV's introduced, from a few manufacturers. These are pretty 
        neat, but TV stations don't broadcast widescreen programming for the most 
        part, so you're limited to viewing "letterboxed" laserdiscs 
        and DVD's (the best way to watch video movies anyway) or using "Picture 
        Outside Picture" (POP) to give you more than one source to watch 
        at a time.
      Some of these 
        sets also let you manipulate the standard image, "converting" 
        the squarish TV picture into a widescreen one, but the tradeoff here is 
        that you skim the top and bottom from the picture in the same way a "pan 
        and scan" video taken from a widescreen movie chops the sides from 
        the picture - or stretch the image from top to bottom and make everything 
        on it look tall and skinny..
      The Next Generation
      The hype over 
        the past decade has been around High Definition TV (HDTV), which is a 
        whole new ball game as far as TV is concerned. HDTV, 
        featured elsewhere in TechnoFILE, substantially ups the picture ante 
        as well as giving you 16:9 aspect ratio widescreen pictures and "CD-quality" 
        sound.
      Great! Unfortunately, 
      for 
        HDTV to work, the broadcasters and the other people who make video programming 
        have to convert, which is expensive and puts a big dent in their short 
        term profits. And they have to do it when only a handful of people have 
        the HDTV systems at home, so they're being forced to deal with two formats 
        (HDTV and the old system) for the next several years.
       HDTV is currently 
        expensive for consumers, too, just like anything else in the world of 
        consumer electronic starts out priced in the stratosphere and slowly becomes 
        affordable to mere mortals. Still, the sets are now out there, and the 
        HDTV revolution is under way.
      In the meantime, 
        many enhancements of the current systems (NTSC, PAL, or SECAM, depending 
        where in the world you live) are being introduced. These include things 
        like "line doublers" that digitally fudge extra scan lines between 
        the current ones. They can do a marvelous job (depending on how much money 
        you spend on the line doubler, of course), though some can be plagued 
        with "digital artifacts" that give an unrealistic and/or soft 
        quality to the picture.
      More important 
        than HDTV in the short term is the exploding channel capacity and new 
        competition to your friendly cable operator. Satellite TV is coming into 
        its own with the introduction of systems like DSS, those 18/24 inch digital 
        dish systems that are being hyped like crazy.
      DSS and its 
        competitors give you a wider variety of channels, including audio-only 
        channels, as well as a broad range of pay per view services. They also 
        offer a better picture than your typical cable system (which until now 
        hasn't had to compete for your dollar - and so didn't) as well as "CD-quality" 
        sound. They also claim DVD-quality picture, but we might argue that point 
        (though they're darn good!).
      So the future 
        of video is bright and in the end will benefit the consumer through better 
        products at lower prices. And the blossoming "500 channel" universe 
        will offer a dizzying range of programs to suit every taste.
      Of course, Murphy's 
        Law being what it is, you'll surf through all 500 channels only to discover 
        there's still nothing worth watching

        Buying Advice" column.
