摘要： A data transmission system in which normal transmission can be performed irrespectively of the inserting orientation of a connector is provided. A transmitting device transmits to a receiving device a differential transmission signal including polarity decision data for deciding the polarity of the connector. Based on the polarity decision data included in the differential transmission signal transmitted from the transmitting device, the receiving device decides whether the polarity of the connector has been reversed or not. When it is decided that the polarity has not been reversed, the receiving device reads data from the differential transmission signal. When it is decided that the polarity has been reversed, the polarity of the differential transmission signal is reversed for data reading.

摘要： To a data reception device, a signal having a frequency of 12.5 MHz and including data is transmitted. The data reception device generates a clock B having a frequency of 400 MHz of (1) in FIG. 8, and performs sampling for the above-described 12.5 MHz signal based on the clock B ((2) in FIG. 8). Then, the data reception device detects zero cross points of the sampled data, and generates a 25 MHz frequency clock signal indicating the zero cross points ((3) in FIG. 8). Next, the data reception device generates, by delaying the generated clock signal by the time amount corresponding to eight clocks ((4) in FIG. 8), a 25 MHz signal indicating symbol points. Thus, symbol points can be detected.

摘要： A scramble system of the present invention including a scramble apparatus and a descramble apparatus is applied to a recording and reproducing system or a transmission and receiving system wherein a frame of a digital video signal composed of a plurality of frames is divided into a plurality of predetermined fundamental video blocks corresponding to recording and reproducing processes. Either one of the recording and reproducing system and the transmission and receiving system executes a reconstruction process such as an interpolation process, a high speed playback process or the like. The scramble apparatus executes a scramble process on the inputted digital video signal in the identical processing manner using the fundamental video blocks in the identical position in each of the frames and generates a scrambled video signal, while the descramble apparatus effects reverse conversion of the scramble process executed by the scramble apparatus using the fundamental video blocks on the scrambled video signal generated by the scramble apparatus.

摘要： The occurrence of malfunction on the reproduction side is avoided by preventing a scrambled signal from being coincided with a reserved word in the signal when a scramble process is carried out in order to release a transmission signal to specific users. The scramble process includes at least one of methods of (1) bit-inverting specified codes of the transmission signal code by code, (2) limiting bits to be scrambled from a specified position in the transmission signal, and (3) limiting codes to be scrambled to specific codes.
