Product Information :  Panasonic DMR-HW120 DVB-T2 Twin Tuner 500GB

HDTV is broadcast in MPEG4 compression and this feature is required in order to receive and decode HDTV (720p or 1080i).

With twin tuners, you can watch one TV channel while recording from another at the same time, either into the built in hard drive (PVR) if featured or to any external recording equipment.

Freesat is a British free-to-air digital satellite television service developed by the BBC and ITV plc. The service began broadcasting on 6 May 2008 and offers a satellite alternative to the Freeview service on digital terrestrial television, with a selection of channels available without subscription for users purchasing a receiver. The service makes use of the additional capacity available on digital satellite broadcasting to offer high-definition channels.

PVR (Personal Video Recorder) which makes videorecording and videostorage possible trough the built in hard drive.

This is how much you can store in your hard drive in gigabytes.

EPG (Electronic Program Guide) is a menu system that helps the viewer to find television programmes or services.

HDMI (High-Definition Multimedia Interface) is the first and only industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable.

Component video is a type of analog video information that is transmitted or stored as two or more separate signals (as opposed to composite video, such as NTSC or PAL, which is a single signal).Most component video systems are variations of the red, green and blue signals that make up a television image. The simplest type, RGB, consists of the three discrete red, green and blue signals sent down three coaxial cables. This type is commonly used in Europe through SCART connectors, in the form of RGB plus composite sync, i.e. four of the wires in a SCART cable are used for the video signal (excluding ground wires). Outside Europe and Australasia, it is generally used for computer monitors, but rarely for consumer TV-type applications.A slightly different type of componentization aims to separate out one colorless component, termed luminance, from components (at least two are needed) that give only color information, termed chrominance. This componentization can be approximated by a linear transformation of the sRGB color space. This is the signal type for images that is usually meant when people talk of component video today. Variants of this format include YUV, YCbCr, YPbPr and YIQ commonly used in video systems.

USB (Universal Seriel Bus) sends bot data and electric current in the same cable. The speed for data transfer is 480Mbit/s.

This means that the box has support or pass trough, audio out (not a decoder) for digital sound such as Dolby Digital 5.1 (AC3). That means that you can get digital surround sound to your reciever, if its broadcasted.

Ethernet is a network standard of communication using either coaxial or twisted pair cable. The most widely used for of LAN communication, Ethernet typically runs at 10 megabytes per second, though newer systems use 100 Mbps and even 1 gigabit of transfer.Ethernet has the IEEE standard 802.3. It has several different flavors, with the original Ethernet designed with 10base5. The "10" stands for 10 megabytes per second. Base is the baseband communications it uses. The "5" stands for a maximum distance of 500 meters to communicate with. Original Ethernet used coaxial wiring, while newer versions use twisted-pair cabling. There are several flavors of Ethernet, including 10Base2 (10 Mbps, 200 meters), 10BaseT (10 Mbps, 100 meters, twisted-pair), and 100BaseT (100 Mbps, 100 meter, twisted-pair).
