Digital TV chip targets Chinese market

Leading mobile TV chip maker Siano Mobile Silicon released today the official launch of its new Mobile Digital TV (MDTV) receiver chip, the SMS118X, targeting China's domestic mobile TV market.

Siano Mobile Silicon has released the SMS118X mobile digital TV (MDTV) receiver chip, aimed at China's domestic mobile TV market.

The chip supports the Chinese MDTV standard: CMMB.

CMMB (or S-TIMI) is the technology developed in China and selected by the State Administration for Radio, Film and Television (SARFT) as the main platform for delivering TV services to mobile devices.

The CMMB network will use both satellite and terrestrial signals to obtain effective coverage in densely populated cities as well as in sparsely populated rural areas.

The pilot launch of mobile TV in China, broadcasted in more than 30 cities over a UHF spectrum band, will be at the Olympic Games in August this year.

Full commercial deployment, including satellite transmission and conditional access system, is scheduled for early 2009, before the Chinese New Year.

Two options are available with the CMMB chip.

The SMS1185 supports antenna diversity - on one single chip - for both the terrestrial UHF signal and the satellite S-band signal.

This single chip can be connected to two UHF antennas and two S-band antennas for maximum performance.

The lower cost SMS1180 supports only one antenna per each spectrum band.

Both solutions exhibit very high sensitivity, excellent mobility performance, extremely low power consumption and the highest level of component integration.

The SMS118X supports reception and display of multiple TV channels in parallel.

In addition, it is a true integrated solution, including two complete, distinct UHF and S-band paths, strong baseband processor for the challenging performance requirements and also all the common interfaces required for the consumer market - USB, SDIO, SPI, Memory-mapped, Transport Stream and I2C.

Unlike competing solutions, the SMS118X does not require any external active component such as memory to support CMMB.
