Abstract
Disclosed is an MPEG data frame and a transmitting and receiving system using the MPEG data frame for enhancing receiving performance of receiver which moves or is stationary. The digital TV broadcasting data frame according to the preferred embodiment of the present invention comprises a data frame which includes at least one data field which has 313 data segments. The first data segment of the data field is a data field sync signal which includes a training data sequence used for synchronization at the receiver, and the other 312 data segments each include a 188-byte transport packet and 20-byte error correction data. Therefore, when null packets are input to the 8 VSB transmitter, 2-level training sync signals are used as training data for an equalizer at the receiver so as to increase receiving performance of a receiver that moves or is stationary.
