TV tuners have analogue and digital covered

TV tuners for terrestrial digital broadcasting are compatible in common casing with both terrestrial digital and analogue broadcasting for Europe and North America.

Alps Electric has developed a new series of TV tuners for terrestrial digital broadcasting, which are compatible in common casing with both terrestrial digital and analogue broadcasting for Europe and North America.

In addition, the company has also prepared products in this series for digital cable TV for China, Europe and other areas.

Terrestrial digital broadcasting is starting all over the world.

However, during the switchover period from terrestrial analogue to terrestrial digital broadcasting in some areas only terrestrial analogue broadcasting is available.

Therefore, it was essential to develop products which are compatible with both terrestrial digital and analogue broadcasting and/or which meets broadcasting conditions in each destination.

Alps used to build multiple models of tuners which were individually compatible with terrestrial digital and analogue broadcasting within the final set.

However this posed problems in both design flexibility and cost as well as not being ideal for the end-user who would like to keep watching TV without having to change TV sets or attach other equipment when the area of residence switches to terrestrial digital broadcasting.

The new TDA Series includes models that are compatible with both terrestrial digital and analogue broadcasting for each area in Europe and North America and models for digital cable TV broadcasting for China, Europe and other areas.

All models come in one common 53 x 38 x 13mm casing, incorporating Alps' original RF circuit technology and high-definition mounting technology.

Improvements in the sealing of the casing minimises tuner noise and improves resistance against noise caused by other parts built into the end product.

Tuners that are compatible with both terrestrial digital and analogue broadcasting for Europe and North America typically suffer from the problem of noise in the tuner causing a deterioration in the reception quality of the terrestrial analogue broadcasting.

In order to overcome this weakness, Alps has built the original circuit into the tuner to reduce tuner noise and to realise higher reception quality for the terrestrial analogue broadcasting.
