A regular television normally transmits at 50 Hz. This means the picture is updated 50 times per second. More expensive and modern televisions now transmit at 100 Hz and above, where each image is updated 100 times per second. The picture becomes quieter and without flickering.

The number after the dot indicates whether the system has a subwoofer (separate speaker). 5.1 means sound with five speakers and one subwoofer. DTS 5.1 and Dolby Digital 5.1 offer support for surround sound to such speaker systems.
4:3 is a screen format for a television. 4 stands for the width and 3 for height, so wherever a TV is, the height will always be 75% of the width. 4:3 was previously the most common TV format, but most modern TV's are now available with 16:9 widescreen format.

Newer networking standards based on the GSM network allow significantly higher data rates than GPRS on the normal GSM network. Data transmission via UMTS is the same as GPRS on the GSM network.
3D Surround Sound
3D Surround Sound is an advanced sound enhancement technology that provides a simulated surround sound effect from stereo sources. This technology allows the sound to be more overwhelming and realistic.
3D Comb Filter
3D comb filter keeps brightness and colour signals better separated in a 3D signal to eliminate false colour, stretching and distortion of the image. The 3D digital comb filter compares the individual frames of the television image to separate the colour information from the black/white signal. You get a sharper image without noise and flicker.
2.1 means one pair of speakers and one subwoofer. 2.1 stereo hi-fi.
Widescreen where the relationship between width and height is 16 to 9. This means that the TV is wider than a conventional TV set with 4:3 format. Cinema format has changed over the years, but movies are now commonly in the 16: 9 format. A widescreen TV will therefore render movies more accurate than a conventional TV set with a more square aspect ratio.
