The trend is clearly towards larger and larger flat screens and ever more complex home cinema systems, that's clearly evident. A new revolution appeared at the IFA 2006: Full HD!

But what is the point of this format and what is the difference to "HD-Ready", which appeared at IFA 2005?

One thing is certain: With Full-HD you have the best cinema experience at home. Razor-sharp images and crisp colors are among the many advantages.

Features include one Resolution of 1920 x 1080 pixels” that corresponds to five times that of conventional television images. Even if the viewer stands close to the flat screen, no visible pixel structures can be seen; Not even when the image is projected onto a large projection surface using Full HD projectors, which were already available shortly after the introduction of the Full HD signal.

To come back to the resolution: In contrast to the term "Full-HD", "Half-HD" is sometimes also used, which does not exist in this form. It should only describe the low resolution of 1280 x 720 pixels, which e.g. B. is required to receive the "HD Ready" logo. This logo was originally created to make it easier for consumers to purchase HD compatible devices. However, it only says that the TV is standardized HDMI-connections are available and it can display 768 lines, which is actually nothing half and nothing whole, because:

 

HD Ready

The resolution of 1280 x 768 specified for "HD-Ready" does not correspond to this PAL-, nor the actual HD format, which means that the television has to interpolate, i.e. extrapolate. It is questionable whether this picture is always the yellow of the egg.
"Full HD", on the other hand, uses the original HD resolution.

For those interested in image processing technology, this can be illustrated with a small example:

You have a holiday picture and want to enlarge it by 20%.
The result is that the pixel structures become clearer than at 100% image size.
"Full-HD", on the other hand, uses the enlarged image (here the 120%) and thus achieves the visibly better result.

However, you should consider that the number of pixels is not the only decisive criterion for modern flat screens and Beamer at a hunt.
The important properties include the ability to display colors with natural luminosity, finely graded contrasts and movements without any blur. The quality of the panel used (key image-generating components) and the quality of the electronic signal processing play a major role here.

 

The "must have“ on the new TV sets with the “Full HD” logo:

 

  • Image display on analogue (YUV-component input) and digital, copy-protected way (DVI + HDCP or HDMI)

  • Support for all HD resolutions, from full images with 1280 x 720 pixels, half images with 1920 x 1080 pixels and "Full HD" images with 1920 x 1080 pixels

  • All at 50 and 60 refresh rates Hertz

  • Receiving films in 1080pformat with 24 frames per second

Although it is an investment for the manufacturer to obtain the license for "HD-Ready" (seal is awarded by the EICTA), it is not checked before the award whether the device really meets the technical requirements. The customer is responsible for this. Unfortunately.

The trade advertises with a wide variety of descriptions:

Some refer to "Full-HD" as "True-HD" in order to use their own sound format "Dolby True HD“ to advertise, the others do it differently:

False labels in electronics stores are sometimes even common practice. Increased at the beginning of the HD era, today only sporadically. However, it is unclear whether this is due to a lack of technical expertise or to attracting customers. In any case, you shouldn't fall for it when a flat screen with 852 x 480 pixels is advertised as "HD Ready". Always keep the above values ​​in mind.

However, since "Full HD" does not come from an organization like EICTA or an association of manufacturers, it is interpreted and used differently from manufacturer to manufacturer.

Remember: HD images can even be received on old tube televisions. However, only the source is HDSignalHowever, what is output is a maximum of a normal PAL signal.

Currently, more than 75% of the televisions sold in Germany are "HD-ready", i.e. completely fit for high-definition television.

 

 

News in Brief:

“Full-HD” is currently the non-plus-ultra of television signals, so to speak. Featured with a resolution of 1920 x 1080 pixels. "HD-Ready" is practically included in the new format, since "Full-HD" can do everything that televisions with the "HD-Ready" logo can also do. Pay attention to the information: The "Full-HD" does not have an official logo, it is displayed differently everywhere; So check whether the device offers all the features that characterize "Full HD".
