A single set of definitions for digital television sets has finally been agreed by the major television manufacturers in the US.

The new agreement will force two manufacturers, Hitachi and Toshiba, to inform customers that their high-definition TVs have a lower resolution than other HDTVs on the market.

Both companies sell digital sets which provide 1,080 lines of resolution (the industry standard for an HDTV) in full screen format, but only 810 lines in “widescreen”, falling below the required number. The agreement means that these sets can keep the title HDTV, but must disclose that this does not apply in “widescreen”.

Under the new rules, high-definition sets must have a digital receiver included, otherwise they must be called high-definition monitors.
