  ANNOUNCEMENT

The President of  The United States had signed The Public Safety Act.of 2005 into law, this act states that by February 17, 2009. The Unites States analog television transmission ( NTSC) is scheduled to come to an end. The new standard in broadcasting will be Digital or HDTV(ATSC).
 
Digital Television has arrived.  Transmitting the information used to make TV picture and sound as data bits allows for higher resolution and dramatically better picture quality and sound as data bits allows for higher resolution and dramatically better picture quality and sound than previously available with analog.  But how can a system operator best utilize these advanced digital signals with the existing base of analog televisions? The answer is to use Microyal's Agile ATSC/QAM Demodulator and Modulator.
 
An alternative is to use Microyal's Digital Head-End System Equipment to pick up digital signal from the Satellites. With use of Microyal's decoder or demodulator, analogue signals (from camera, dvd player) can be converted to the ASI stream through the encoder, Remultiplexer to the QAM modulator. The result is high picture and audio quality of digital television.
