By: supereworld 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. http://www.super- End
