The government has mandated that analog TV signals be replaced with digital TV signals in June 2009. They even offer coupons to help pay for a converter box. What they don’t tell you is that for you to experience High Definition TV you will need a TV screen capable of producing 720P resolution. |
For this reason Concertone is offering the ZX690 full featured Multimedia System with a Venturer 22 inch LCD HDTV. A HD (High Definition) solution without having to hide a separate box and work with another remote control only to get SD (Standard Definition) TV on your old TV or LCD monitor. |
|
The TV will work with cable and satellite boxes and receive over the air HD digital broadcasts and display resolutions up to 720P. It has a Composite Audio Video input as well as S video and Component inputs. It will also work as a computer monitor and it has a PC audio input. |
|
The 4th Generation ZX690 features include an AM/FM/Weather Band; 5.1 Surround Sound including outputs for an 8" Subwoofer; "A", "B", "C" Speaker Zones; CD, DVD, MP3, MP4, SD, USB, Multiple Audio and Video inputs, Line outputs, and up to 3 Video outputs for convenience. Because both units operate on 12 volts DC there is still no need to be plugged in to 110volts or have to run a noisy generator for hours. Available for purchase now!!! Click here to order!!! |

WHAT IS THE DIGITAL TV TRANSITION (DTV)
NTSC is a color TV standard developed in the U.S in 1953 by the National
Television System Committee (NTSC) for describing “Standard
Definition” analog video. NTSC format is used in the United
States, Canada, Japan, most of the American Continent and in various
Asian countries.
ATSC is an advanced terrestrial digital television broadcasting standard and to facilitate interoperability with other media. The Advanced Television Systems Committee, Inc. (ATSC) is an international, non-profit organization that developed voluntary standards for digital television. This is referred as “High Definition” (HD).
The era of analog broadcast television (NTSC) in the United States will end as the nation's full power television stations complete their transition to an all-digital system (ATSC). This change will mark the end of the traditional analog method of broadcasting over-the-air television. Canada has a similar analog TV termination date set as August 31, 2011.
HOW DOES THIS AFFECT ME AS A RVer
If you currently receive NTSC analog television over an RV antenna,
you’ll need to take action to continue watching your favorite
stations. The 22 inch HDTV features an ATSC TV tuner that works by generating audio and video signals that are picked up from over-the-air TV broadcasts. The tuner provides the following functions:selective
tuning,
demodulation,
transport
stream demultiplexing,
decompression,
error
correction,
analog-to-digital conversion,
AV
synchronization
and media
reformatting to fit the specific type of TV screen optimally.

| Selective Tuning | |
| Selective Tuning is the process by which an RF channel is selected by a receiver from within a band of transmitted RF signals. The tuner usually performs the function of frequency-agile selection, along with rejection of unwanted out-of-band signals. | |
| Demodulation | |
| Demodulation means that the signal from the tuner is transformed into a usable signal that a TV set can use to produce quality images and sound. | |
| Transport Stream Demultiplexing | |
| In the US, multiple digital signals are combined and then transmitted from one antenna source to create over the air broadcasts. An ATSC receiver then is able to decode the transport stream and display it on a TV set. | |
| Decompression | |
| Since digital signals that are broadcast over the air are compressed (packed smaller), once they are received by the ATSC tuner, these compressed packets of digital data are then unpacked to their original size, or using the proper term, decompressed. | |
| Error Correction | |
| Error correction is a technology that is used by the ATSC tuner to make sure that any data that is missing can be corrected. For instance, sometimes interference or a poor-quality signal will cause the loss of data information that the ATSC tuner receives. With error correction, the tuner has the ability to perform a number of checks and repair data so that a signal can be viewed on a TV set. | |
|
|
| AV Synchronization | |
| AV synchronization is the coordination of audio and video signals being displayed on a digital TV in proper time. AV synchronization ensures that the audio does not lag behind the video that is being displayed on the TV set or vice versa, so that both audio and video are in sync. | |
| Media Reformatting | |
| Media reformatting is extremely important because the formatting of images on TV sets differs significantly according to the technology employed. For instance, some televisions have an interlaced picture, whereas others have a progressive-scan picture. Different televisions have a different aspect ratio. | |
