Objectives: In this paper encoding techniques used in the Digital Video Broadcasting-Terrestrial (DVB-T) system have been discussed. The paper focuses upon the comparison between the different types of encodings as a part of the DVB-T standard. Methods/Analysis: Different types of encoding methods which could be the part of the DVB-T standard have been considered .The system used is able to measure and analyze the performance by using different encoding techniques along with the Orthogonal Frequency-Division Multiplexing (OFDM). Findings: DVB-T was developed by the Digital Video Broadcasting (DVB) Project that was basically for broadcasting. The compressed images, digital audio, compressed videos and other forms of data in Moving Picture Expert Group (MPEG) transport stream, through OFDM modulation is transmitted by this DVB-T system. Novelty /Improvement: In the DVB-T Reed Solomon encoding is used to encrypt the data. Hybrid coding has been proposed as the way to improve the performance.
