South Korea's electronics giant Samsung Electronics has successfully developed a pair of chips that can receive and decode to four different mobile digital TV systems. With this invention, mobile phones will be able to watch television in any country in the world, while sizes are getting smaller.

Specifically, these chips are compatible with the DVB-T / H standard being applied in many European countries, the standard DAB-IP is piloting in London, the ISDB-T " 1-seg " system of Japan and the DMB standard Korean ground. Samsung said it was the company's first " four-standard " chips built with 65-nanometer technology (1 nanometer is 1 billionth of a meter).

Not only Samsung, all chip makers are trying to develop and apply smaller chip manufacturing technologies (45 nanometers overall, while Intel has just announced that it will jump to 32 nanometer technology straight). .

Compared to the traditional 90-nanometer method, technology 65, 45 or 32 nanometers allows the creation of smaller chips that consume less power while the performance is significantly enhanced. These are particularly important factors for portable electronic devices.

The chip can watch all four mobile TV standards images 1 Source: Mobileafrica In these chips, one will assume the role of a multi-band receiving antenna - specializing in analog television reception. The other chip carries the task of decoding channels, ie turning analog signals into digital signals for processing.

The duo can handle the VHF, UHF and L frequency bands that the vast majority of mobile TV services are currently in use.

Mobile digital television is gradually becoming a popular service in many countries around the world. Nearly all the new high-end phones launched in Japan and Korea have the function of watching digital TV. . In addition, this feature also appears more and more in laptops and portable music players.

However, the biggest challenge on the take-off path of mobile TV is that there are so many different technological standards coexisting, making it difficult for equipment manufacturers and consumers to be confused. blindness

Samsung believes that a "4 standard " chip like this will help solve the problem. As planned, the samples will be tested in the next month, and put into mass production in the fourth quarter of this year.
