March 11, 2010 - PRLog -- STMicroelectronics (ST) as a digital TV system chip solution provider and leading supplier of set-top box chips, has recently released a new Europe-wide can be front-end processing of terrestrial digital television broadcasting capabilities COFDM demodulator chip STV0361, the new device fully in line with the European COFDM (coded orthogonal frequency division multiplexing technology) demodulation standards, including the European Broadcasting Union Digital Video Broadcasting - Terrestrial (EBU DVB-T) specification (ETS 300 744), in particular with the NorDig unified standard 1.0 .1 version.

The new chip used to design digital TV and digital and analog hybrid TV, digital set-top boxes and digital video recorders, with industry-standard chip, ST OMEGA back-end seamless connectivity, for price-sensitive digital consumer markets highly cost-effective chipset. This device is compatible with the hardware and software market is currently widely used STV0360, therefore, take advantage of this chip features without the need to improve development and testing work. STV0360 protection needs of the echo from the set-top box controller, while the STV0361 echo protection fully automated.

And satellite television networks and cable networks compared to terrestrial challenge even more severe, the surrounding buildings and moving objects will produce multi-channel echo, single-frequency transmitter network will also be similarly affected, the ground demodulator must be overcome These "non-pure" signal. In addition, man-made radio interference, such as electrical, automotive ignition systems and lighting switches, as well as natural sources of interference such as lightning, can cause picture quality is not clear or disappear.

STV0361 outside the guard interval sync up to a maximum of 260 milliseconds, so capable of handling signals containing such echoes. In accordance with NorDig requirements, STV0361 using adaptive channel correction techniques to detect the time-frequency processing in mobile applications common or Doppler shift signals received from a moving object echo signals.
