Provided are a digital video data transmission system and digital video data transmission method. The digital video data transmission system includes a transmitting unit transmitting valid first data in input digital video data having spatial locality to a bus as output encoding information without bit-inversion coding the first data, bit-inversion coding previous data of output encoding data corresponding to the input digital video data based on differential values of adjacent digital video data, and transmitting the bit-inversion coded value to the bus as the output encoding information; and a receiving unit not decoding output encoding information transmitted in parallel through the bus, i.e., the first data, but decoding output encoding information transmitted in parallel through the bus based on the differential values. The output encoding information includes the output encoding data and coding enable information that indicates whether to bit-inversion encode previous data of the output encoding data. The digital video data transmission system and digital video data transmission method can reduce the number of transitions of bits included in the digital video data transmitted through the bus, thereby reducing power consumption and electromagnetic interference. |
