Portable HDTV Set
I am looking to buy a PORTABLE HDTV set.
Are there any available...I can't seem to find anything but LARGE sets that are anything but portable. Also I would like to hear anyone's experience with a HDTV set that is being used while traveling in a RV. Thanks TMT |

These are all under $500. NONE of them are genuine HDTV. These are just HD-ready or ED-ready. NONE have an ATSC tuner so they require an external STB tuner to get HD broadcasts (which will subsequently be reduced in quality to fit the 4:3 screens they have). Note that an external tuner may be fine for a large screen home theatre system, but they are inconvenience for a portable. The ideal portable TV will include a 16:9 screen, ATSC/NTSC tuner (for North American markets), and correct handling of all ATSC formats to be sure resolution is never any less than what that small screen can show (it won't be anything like a large screen, but that is no cause for dumb engineering that downgrades video below the 480 size before displaying it). An integrated Blu-Ray DVD player would also be nice when that technology finally makes it to market. The ability to also handle 576i/p, 25/50 fps, DVB-T, world channeling, and 100-250v power in the mains adapter, would be a big plus. Cable TV (QAM) would also be a plus for many people. | Sharp LC-13B6U-S 13" AQUOS HDTV-Ready The aspect ratio is only 4:3. The tuner is only NTSC (no ATSC). Apparently it can do "HDTV" only via video input, up to 480p (really just EDTV). but it can do PAL and SECAM (maybe only via video in). | Zenith Z15LA7R 15" Flat Panel HD-Ready LCD TV This one is also 4:3. No mention of a tuner is given, but no mention of ATSC certainly indicates it has no such capability. | Philips 15PF8946 15" HDTV-Ready Flat Panel TV Another 4:3 unit. Again, no mention of ATSC. This one does have an FM (radio) tuner. | Sharp Aquos LC-15B9US 15" HD-Ready LCD I see no "LC-15B9US" but there is a LC-15B6US at Amazon. It says ED-ready (not "HD-ready") and appears to be a larger screen version of the LC-13B6U-S. -- ----------------------------------------------------------------------------- | Phil Howard KA9WGN | http://linuxhomepage.com/ http://ham.org/ | | (first name) at ipal.net | http://phil.ipal.org/ http://ka9wgn.ham.org/ | ----------------------------------------------------------------------------- |

I would have to agree....and so why I asked the original question to
see if I was missing something offered in the marketplace. I guess one just needs to wait for the manufacturers to offer the product for a market segment they have yet to address. TMT |

The DTV standard for over the air broadcasts requires a good and stable
incoming signal from the antenna. In the RV if you are parked and can orient the antenna you should be fine. If you want to use it while driving, it is not going to work. There will be too much 'ghosting' of the incoming digital signal and the tuners won't handle it well. I am not certain there will ever be a market segment for what you are searching. |

I consider it to be a faulty standard.
Do you remember the early portable CD digital audio players? Remember the skipping? Note that manufacturers had to build buffering and better pickups to take care of the problem. Same evolution with video. Kids are in the back of the SUV/RV watching digital televison...dropouts, ghosting, etc....guess what..manufacturers will be forced to provide the service the customer demands. Until then I and many others won't be spending money on DTV. TMT |

Until then I and many others won't be spending money on DTV. TMT Portable and mobile are a big deal and will be big business in most countries. The recent IBC show in Amsterdam was 20% bigger than last year mostly because of the interest in mobile DTV. In the US we do have two ventures both targeting cell phone DTV, Qualcomm and Crown Castle but soon you will hear of other ventures targeting vehicles, laptops and other larger screens than cell phones. Auctions to be held in 2008 will allow more such DTV that works mobile and portable. Stay tuned. The disastrous DTV transition in the US has held back progress but it will soon be of little interest as new broadcasters come on line who do care about OTA DTV broadcasting unlike the current broadcasters who live and die by must carry over cable.

I would agree....would you want your cell phone to come with a cord
that you had to plug into a stationary socket before using it? HDTV will not be a replacement for NTSC until it does everything that NTSC does now...everything. And the public will not accept it until it does everything that it replaces. NTSC will be with us longer than anyone wants to admit. TMT |

Over the next few years the standard for portable/mobile will be set by broadcasters like Qualcomm, Crown Castle and others all of which will be using COFDM based modulations that will be extremely robust. Anyone trying to use a junk modulation like 8-VSB would be crazy and whatever product they tried to sell would be laughed off the market. This is what COFDM can do in a market like New York City. 8-VSB still does not work in New York even for fixed receivers on rooftops with fancy powered and rotored antennas let alone mobile with half inch antennas like Qualcomm and Crown Castle will offer. www.viacel.com/bob.wmv Japan will start a mobile COFDM cell phone service in a few months. The antenna is an inch at best. http://www.dibeg.org/news/news-4/news-e4.htm#dn058e Bob Miller |

Sure don't have anything like that available at our PX or through AAFES Online. Cheapest digital ready TV we have access to is $1000, 24" screen, and has no digital tuner even available for it yet. |

The screen aspect ratio has nothing to do with whether a tv is HDTV or
not. If the tv can display the lines of resolution at the appropriate scan rate for HDTV, then it is high definition. Just because it may have bars on the top and bottom, or on the side when displaying a different aspect ratio has nothing to do with HDTV or not. |

I guess if it shows the correct resolution but why anyone would want to buy something that bass-ackward, I don't know. May as well just buy a smaller TV with the correct aspect ratio. True, and this is likely a piece of junk tv, but the poster I was responding to said that you couldn't get even an HD monitor for less than $1750.

What is the 'correct' aspect ratio then?
Most people for the next 3 or 4 years are going to have 95% or more stuff available over cable at 4:3 aspect ratio, why would they want to buy a tv that would have those annoying bars on the sides for 95% of what they are going to watch for a next few years? Seems to me that it would be bass-ackwards to buy a tv set that does not fit most of your available viewing material. The problem so far in being able to get enough HDTV sets and ATSC tuners available has been the widespread penetration of cable. To use the still standard cable, you need a standard tv set. Cable companies have been slow to provide HDTV capable signal at reasonable cost. |

I actually prefer 4:3 HDTVs for now since most of what I watch is still 4:3. Also, a 32" 4:3 set is about the same price as a 30" 16:9 set and will give you the same size 16:9 picture. Plus, you get a bigger 4:3 picture for free if you don't mind a set that takes up a little more space. Andy Cuffe -- Use this address until 12/31/2005 -- Use this address after 12/31/2005 |
