Abstract:
A frame structure having a plurality of unit frames, each unit frame comprising:a frame field including a frame bit that controls data transmission; an information field including information bits of digital video signal data; and a channel coding overhead field including channel coding overhead bits having correcting data to correct an error in the digital video signal data, wherein the plurality of unit frames form a multi-frame used to multiplex digital video signals of at least two channels, the multi-frame having a size of 4760 bits and each unit frame having a size of 680 bits, and wherein each unit frame includes eight groups of 85 bits, and wherein a first bit of each group is allocated as the frame bit, a 2nd bit to a 75th bit of each group are allocated as the information bits, and a 76th bit to an 85th bit of each group are allocated as the channel coding overhead bits.
