DVB-C. ⢠It is the short form of Digital Video Broadcasting-Cable. ⢠Uses MPEG-2 or MPEG-4 compression. ⢠Uses RS encoder as FEC. ⢠Interleaving module is used in the chain. ⢠Cable TV signal is carried using coaxial cable or fibre cable from cable service providers to the subscribers. ⢠DVB-C uses frequencies from 55.25 to 403.25MHz.
The Viterbi Decoder subsystem interprets the soft-decision numbers and uses them to decode the punctured convolutional code properly. To examine the exact mapping more closely, see the DVB-T 64-QAM Demapper subsystem, as well as the dvbt_qam variable. A traceback depth of 136 in the Viterbi Decoder block.
The main differences between DVB-T and DVB-T2 are summarized in table.1. The first module in the system is the input pre- processor, this module converts input data stream into DVB-T2 BB frames (Base Band Frames) [2],[3].
Similarly to DVB-T it supports both SDTV and HDTV broadcasts. The main difference between these two systems lies in their transmission methods. DVB-T uses terrestrial radio waves to transmit signals while ATSC uses 8VSB modulation technique which transmits signals over UHF or VHF bands using an antenna instead of a satellite dish or cable
The definition and measurement of the RF level are exactly the same as for DVB-T. As a voltage value, it is simply the root mean square (RMS) of the voltage of the DVB-T2 source; as a power value, it is the average power of the signal (PAVG=VRMS¡RLoad). A DVB-T2 measuring receiver detects the RMS value of the voltage over a 50 or 75-Ohm

T) [3] in Japan. Among them, DVB-T plays the most important role. Since first approved in 1997, DVB-T has become the dominant terrestrial broadcasting standard in Europe and is also popular in other continents. By June 2008, DVB-T services have been launched by 33 countries and territories. After 12 years of developing, the Chinese Digital
