Yeah I've heard that, but can't that be fixed simply by boosting more power to the digital stream? Yes it could but that would defeat one of the reasons to go digital. Digital mode is supposed to save on transmit power. -- Telamon Ventura, California |

The reason are several but paramount is the fact that the implementations are old technology...... Old? Both HD Radio and DRM (and also DAB+) are using the latest MPEG4 HE-AAC+SRM codecs. That's the newest and most-advanced digital compression standard currently available. The modulation is COFDM - also one of the newest ideas available for sending data via broadcast. CODFM has been around for decades. It is not a new idea. The concept of data compression has been around for decades. It is not a new idea. The best match so far with the applied technology is FM because it most closely emulates the conditions or transmission path for which those outdated ideas were originally conceived. Daytime AMBCB comes in next and nigh time AMBCB and short wave come in last. Interesting. First, what is AMBCB? The AM broadcast band. Second, why do you rank AM lower than FM? I don't rank it lower in preference. I rank it higher. HD on AMBCB is worse than on FM. And why do you rank skywave transmission as last? I don't rank it last in preference. It is the worst path for HD or DRM. Arguments that current digital broadcasts by proponents fall flat because everyone has or now realizes that this type of transmission has its own downfalls compared to analog. Such as? You keep telling me "digital has downfalls" but so far you've not told me what they are. Please share that information, because I'm curious to know. Well I'm not gonna do that. You are a proponent of HD so go read up on it. You should know about what you promote beforehand. Arguments of proposed improved digital broadcast by proponents are just collections of insipid stupid ideas like using additional bandwidth or more power or just reduce the coverage area of a transmitter. Just more dumb-ass ideas on top of the current old and unsuitable concepts Why are these idea "dumbass"? Please explain. Basically any time you do not address the problem and try to band aid it instead you make things worse instead of better. The solutions proposed above are worse than the cure. And just as bad as the poorly considered technology is the implementation where the whole of the band is used instead of just a part so a great deal of chaos ensues generally ****ing people off. How would the FCC go about using "part" of the band in its transition from AM to Digital, or FM to Digital? Well, they could have allowed HD on just the expanded part of the band for instance then the rest of the band would be OK. But don't worry digital mode proponents; the hilarious HD troll Eduardo I've not met him yet. He posts here numerous times a day. You won't be meeting him just reading his hubris. -- Telamon Ventura, California |

You're silence has totally failed to convince me (or anybody who might be "on the fence" and undecided) that HD is bad. Alright. Here's the reasons I like HD: - analog sucks like a scratchy record - lack-of-variety sucks - - Once analog is dead, Digital AM will have the sound quality of FM (10 kHz wide) or even CD (+5 khz wider), so AM radio can carry something other than just talk. Like maybe some music that doesn't sound like its coming out of a telephone (example: Radio Disney AM). - - Once analog is dead, Digital FM will be able to offer 3-4 times as many channels across the band. And Classical Radio stations will be able to present it the way it was meant to be heard (300 kbps surround). Hybrid Digital Radio is a *good* thing. As good as the internet radio. As good as the music coming out of my Ipod. As good as the HDTV that is replacing blurry NTSC. |

As good as the HDTV that is replacing blurry NTSC. 1) Most internet radio is low bitrate and sounds like hell. 2) I don't know what bitrate you're using on your ipod, but a lot of people are using 64 or 96 k/b mp3 bitrates that sound like hell warmed over. 3) "HDTV" is not replacing "blurry NTSC". DTV will do so. Most programming on DTV is NOT HD, and may never be. It's 480i or 480p, which is supposed to be the digital equivalent of NTSC, but in reality is loaded with artifacts and pixelization. True HD does look pretty good, but to date the stations have nowhere near the useful coverage of their analog counterparts (people in the sticks can't watch them). |

True HD does look pretty good, but to date the stations have nowhere near the useful coverage of their analog counterparts (people in the sticks can't watch them). Cable TV penetration is about 68% to 72%, depending how the source calculates..... satellite TV was at 24% last December, so we have less than 5% to 6% of America that gets off air signals. There is no pixilation of TV delivered by copper, and very limited breakups from satellite, usually weather induced. |
