Alps Electric have developed new TV tuners for terrestrial digital broadcasting - “TDA Series” - which are compatible in common casing with both terrestrial digital and analog broadcasting for Europe and North America. Shipment of samples commenced this March. In addition, we also prepared products for digital cable TV for China, Europe and other areas in this series.

Terrestrial digital broadcasting is starting all over the world. However, we are now in the switchover period from terrestrial analog to terrestrial digital broadcasting. So in some areas only terrestrial analog broadcasting is still provided. That being the case, a set product which is compatible with both terrestrial digital and analog broadcasting or one which meets broadcasting conditions in each destination was essential to develop.

We used to build plural numbers of tuners which were individually compatible with terrestrial digital and analog broadcasting into a set product. However this posed some problems in design flexibility and cost.

And for end-user convenience, it would be ideal to keep watching TV without having to change TV sets or attach other equipment when the area of residence switches to terrestrial digital broadcasting.

This series carries models that are compatible with both terrestrial digital and analog 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 casing realized through our original RF circuit technology and high-definition mounting technology.

Alps Electric realized a single casing size of 53×38×13mm (W×D×H) that allows compatibility with all broadcasting standards and configurations in Europe, North America and China. Mounting a tuner which meets standards of each area contributes to design flexibility for set makers who develop set products in common global designs.

Improvements in the airtightness rate of the casing, restrains tuner noise and improves resistance against noise caused by other parts built into the set product.

Tuners which are compatible with both terrestrial digital and analog broadcasting for Europe and North America suffer from the problem of noise in the tuner deteriorating the reception quality of the terrestrial analog broadcasting. So, to overcome this weakness, we built the original circuit into the tuner to reduce tuner noise and to realize higher reception quality for the terrestrial analog broadcasting.
