DVB-T receiver – Everywhere TV

DVB-T is the acronym for Digital Video Broadcasting – Terrestrial and simply means digital terrestrial television. DVB-T was introduced in 2002 for Germany and gradually replaced the analogue antenna television. The antenna television was not completely abolished, since it represents an alternative to satellite and cable and is to be maintained as third receipt possibility. Instead, the digital antenna television was introduced. The digital, terrestrial version has been and will be further modernized and should be available to the widest possible audience. In order for many states and German cities can receive DVB-T, the network was built up in 2008. DVB-T television is transmitted via broadcast stations and the reception is only with a DVB-T enabled receiverpossible. The receiver is already integrated in modern televisions, or available as an external receiver on the market. Other variants are small DVB-T receiver Sold as USB-equipped sticks, making All-TV accessible to the computer. The trick of DVB-T is that it is not only on the domestic sofaor generally at home is ready to receive, but can be seen everywhere with the right equipment. This equipment includes a receiver as well as a antenna, DVB-T antennas are also available cheaply online or in electronics stores. Below is a receiver example to illustrate the versatile features of DVB-T receivers.

DVB-T receiver – functions (with product example)
The functions of the receivers vary from model to model. One thing all receivers have in common, they receive DVB-T signals. The frequencies of the DVB-T signals are u. a. between 698 to 786 MHz. The channels transmitted via DVB-T could theoretically also be broadcast in HD resolution, but the broadcasters broadcast via DVB-T only in SD resolution. The difference between HD and SD is in the number of pixels shown. The SD resolution in PAL is in the range of 720 x 576 pixels, and in NTSC the resolution reaches 720 x 486 pixels. At the time of DVB-T introduction, the receiving devices such TVor PCs with a higher resolution do not do anything yet, causing the TV channels to continue to broadcast digital TV in SD resolution. Meanwhile, most devices have Full HD resolution or are HD Ready. The HD resolution allows the display of television pictures with 1280 x 720 pixels. There are even resolutions with 1920 x 1080 pixels possible. The broadcast of television programs in HD resolution was not initially introduced for DVB-T, but was reserved exclusively for satellite TV and cable television. The DVB-T standard still does not provide HD resolution, but the terrestrial antenna DVB-T will soon be replaced by a more modern version, the DVB-T2.

An example of one DVB-T receiver with versatile features is the Xoro HRT 7524 HD DVB-T receiver. The HD resolution in this case, however, refers to a coding that is not received in Germany. It will continue to be sent and received in SD standard resolution. The Xoro DVB-T receiver receives free, terrestrial television as well as radio programs. Furthermore, the device has a time-shift function. For recording programs and using the time-shift function, an external storage medium (USB memory) must be connected. The time-shift function makes it possible to watch a TV program with a time delay. The receiver is compatible with the formats FAT32 and NTFS. The Xoro HRT 7524 receiver also supports audio and video formats such as MKV, AVI, MPG, MPEG-1, MPEG-2 and MPEG-4. This means that audio and video files can be played back from an external USB storage device via the receiver, even in HD. Furthermore, the receiver offers a USB interface as well as an HDMI interface and the well-known SCART connection. If you want to see content from an external storage medium in HD resolution, the receiver via HDMI cableconnect to an HD-capable device.

DVB-T receiver – further development
The advancement of the DVB-T receiver is closely linked to the newly introduced television standard. By 2018/2019, DVB-T television will be replaced by DVB-T2-HD television. That’s why receivers are offered that can meet both standards. These DVB-T / -T2 receivers receive the well-tried all-over television and can simultaneously decode the new DVB-T2 television with HVEC (H.265) standard.
