A curved screen has a dramatic stylistic impact when furnishing an office or a home. At the Consumer Electronics Show in January 2014, curved screens were among the most quoted attractions. At present, all products are in the very high-end segment and in OLED technology. If we also consider the need to apply complex image…
It is not correct to say that you have to connect the TV to the telephone wire (better said ’twisted pair’). It is correct, however, to say that the TV be connected to a device for access to the Internet. In most homes such device is an ADSL router , which accesses the Internet through…
Sure! A 3D TV is also capable of displaying 2D programs, i.e. SD and DVD (which are in 576p format, in Europe), as well as HD and BluRay (which are in 1080i25 or 1080p50 mode). This is precisely why a 3D TV generally has a button for switching from 3D mode to 2D mode. Naturally,…
Let us clear the obvious case of three displays with same diagonal, placed next to each other: there is a certain distance at which you can tell whether they have different resolution images. Let us focus on the case of a single TV. To tell the difference between HD and Ultra HD, but also between…
Bandwidth resources needed to broadcast channels on 4K or in 8K are just not available as of today. However, the problem is not only related to non availability of bandwidth, it is mainly connected with investments and time it takes to upgrade the whole chain of production, post-production and distribution. For 4K there exist at…
Since 2013, 4K resolution has been made available in high-end TVs but for the moment it is accessible only through satellite channels or through special media-players, with a built-in hard disk or solid-state-disk, where 4K content may be preloaded at factory time and more content can be downloaded from suitable network or cloud servers before…
Of course, these are programs and movies in digital format, otherwise they could not even get through the Internet. They can be standard definition (SD), but often also in lower definitions (especially when the terminal is a smartphone), or high-definition. Of the two main formats consolidated for high definition, normally format 720p is chosen (whereas…
At first it must be said that the satellite platform is able to bear a number of channels, much higher than the terrestrial platform. The reason is purely technical, due to the inherently larger bandwidth of the satellite platform. For example, in a typical Italian region there are between 200 and 300 programs available on…
For sure, image quality improvement is not just a matter of subjective perception, but indeed the effect of more information actually available. The level of detail gets to be five times higher than with standard definition: it goes from a frame of 576 x 768 = 442k pixels to one of 1080 x 1920 =…
Digital television is a technique of representation of the video and audio signal into digital form, i.e. as a sequence of binary digits. The digital video signal is inevitable for computer storage and servers, but also extremely effective for a true broadcast-quality signal. In broadcasting, terrestrial or satellite, digital technology has been gradually adopted since…
