This is a new format, and some UHDTV’s have appeared on the market. Sometime people call this “4K”. The picture size is even greater than HD, and is increased from 1920 pixels wide and 1080 pixels tall (HD) to 3840 pixels wide by 2160 pixels tall (UHD). That’s about four times more definition.
This is in its infancy, and although there are TV’s on the market, there is not yet a transmission method that broadcasters can use, but there is a great deal of development of this new technology. -
Original HDTV programming is made in the 16x9 (1.78) aspect ratio, which fits the dimensions of HDTVs which are Widescreen. However, many theatrically released films are made in either the 1.85 or 2.35 aspect ratio, which is even wider than the 16x9 (1.78) aspect ratios of HDTVs.
Therefore, when viewing these films on an HDTV (if presented in their original theatrical aspect ratio) - you will see black bars at the top and bottom on your 16x9 screen, because we like to show you the film way it was meant to be seen on the cinema-screen. For upconverted legacy 4x3 programmes , you will sometimes see black bars on the left and right.

Where we can acquire a programme or a film with surround sound, we use it. This tends to be movies, and blockbuster U.S series. More recently there have been a few UK programmes delivered with surround sound.

Some of the older programmes we broadcast weren't made in HD, so we have to “upconvert” those from standard definition (720x576 pixels), but since 2011, we requested all of our commissioned programmes to be made in HD.
