Discussion for Why Digital TV Won't Kill Discs Soonhttp://www.jerf.org/iri/post/2530#CommentsDiscussion for Why Digital TV Won't Kill Discs Soonen-usSat, 21 Jul 2018 00:04:38 -0000 by Jeremy Bowers http://www.jerf.org/iri/post/2530#comment8<p>True, at least for video. I had a Series 1 for a long time (14 hours at the lowest bit rate), and most of the time it was set to the minimal encoding bitrate. Now that we have a Series 2 (40 hours at the lowest bit rate), I'm a little more willing to move up to Medium for some shows we really like, but I still tend to use the minimal one.</p> <p>I'm pretty certain I'd have to amp up the bitrate if I got a bigger TV or routinely watched it more closely, though.</p> <p>Audio artifacting I can't ignore, but I'll freely admit my brain seems wired to be more audio-oriented than most people. I couldn't stand the bass in the dorms (and I don't just mean "lightly annoyed", I mean like I'd have to leave sometimes before I started hitting things), while my roommates sometimes were sleeping through it. Fortunately since audio is so much smaller than the video this is rarely a problem in broadcast video.</p> <p>I think it's really the marketing that bothers me. Part of what prompted this rant was my Uncle-in-law, who recently came by some smallish plasma screen televisions, about 20-25 inches. He played a standard-def DishTV signal into it. That's the first time he ever really saw the artifacting (the fine print in a Jeep commercial, white text on black background, probably the worst static case), and it surprised him because he was under the impression that the DishTV was supposed to be better than analog cable in every way.</p> <p>DVDs can throw enough bits at that case that you have to freeze the frame and zoom in to really see the fringing.</p> <p>My favorite "low-bit rate TiVo" moment is when a show for some reason or other cuts to an entire screenful of static. You'd get an <a href='http://en.wikipedia.org/wiki/Video_compression_picture_types'>I frame</a> that covered just less than half the screen, and the B frames were lucky to get a tenth of the way down.</p> http://www.jerf.org/iri/post/2530#comment8 by albertel http://www.jerf.org/iri/post/2530#comment7<p>Quoting: "once you start to see and hear the digital artifacts, you can't stop hearing and seeing them."</p> <p>But you can stop caring about it.</p> <p>I know this cause of my TiVo.</p> <p>My Series 1 TiVo did a great job on compression at Medium quality, my second one (which targets a resolution and bit rate to fit the included DVD burner) looked noticably worse when I got it and Medium quality, I toughed it out for month complaining about how much worse it looked and much it annoyed my.</p> <p>3 years later while I can still see the artifacts I've learned to 'look through them.' And it doesn't rise to the level to annoy me almost ever. </p> <p>One funny artifacting bit, the episode of "Foster's Home of Imaginary Friends" calle "The Trouble With Scribbles" features characters that are localized static. It was neat seeing the scene's details degrade everytime a "Scribble" entered the screen and then recover when they left the screen. It was a great demo of fixed bandwidth encoding.</p> http://www.jerf.org/iri/post/2530#comment7
