What Does HDTV Stand for?

HDTV is an abbreviation of the term original English High-Definition Television, whose translation to Portuguese is the same as digital broadcast data TV, and the screen resolution of the devices is high if you compare with the technology of the formats that precede it such as, for example, PAL, SECAM, or NTSC.

One can say that the transmission signal of the apparatus developed with the HDTV system is digital. For now, its implementation in a certain way coincides with the introduction of the call DTV or digital television, which had its origin in the United States around the 1990s.

The HDTV technology is different from the full HD (Full High Definition), whose meaning in Portuguese is “full high definition”. One of the main differences between the two technologies with respect to the resolution. In the apparatus, the HDTV has resolution of 720 lines progressive (or 1280 x 720 p), while in the devices in Full HD resolution reaches higher numbers, that is, 1080 lines interlaced (or 1920 x 1080 (i) or 1080 lines progressive (1920 x 1080 p).

When you enter letters after the number of the resolution is to indicate the update switched the lines. In this mode, the letter “i” indicates that the update occurs simultaneously between the lines, since the letter “p” is to point out that the image has a higher quality.

These are devices that are not able to transmit high definition images. To receive properly the signals it is necessary to use a HDTV receiver or an HDTV set called set top box.

Other solutions are the following: hdtv adapter, hdtv online (online channels), hdtv antenna (that can be bound only in the device) and hdtv android (which is available as appliance or application). It is speculated that in the future the videos can be created in high-definition.
