摘要： A data transmission device (1a) generates and transmits a lock signal for establishing clock synchronization with data transmission devices (1b-n). The data transmission device (1a) is capable of generating a pattern 1 lock signal for giving a notice of start of communication by use of data subjected to eight-value mapping, and a pattern 2 lock signal for giving a notice of start of communication by use of data subjected to four-value mapping. One of the two types of lock signals is transmitted to each data transmission device. Determining which lock signal has been received enables each data transmission device to give a notice of data communication method prior to training.

摘要： In the case where transmission and reception is made impossible at a certain portion, a data transmission system configured in a ring LAN performs an initialization process for a physical layer (a transmission/reception section 4) repeatedly, thereby setting as a master a data transmission device which is located most upstream in electrical communication from a disconnection point. With that data transmission device being the master, an initial setting of the physical layer such as a clock synchronization with another data transmission device or the like is established, and an initialization process for a data link layer is performed, whereby subsequent data transmission and reception is enabled. That is, the data transmission system configured in a ring LAN is able to perform communication using transmission lines excluding a damaged point even in the case where transmission and reception is made impossible at a certain portion.
摘要翻译：在某一部分不可能进行发送和接收的情况下，在环形LAN中配置的数据传输系统重复地对物理层（发送/接收部分4）进行初始化处理，从而将主机设置为数据传输设置在断开点处的电气通信中最上游。在该数据传输装置为主机的情况下，建立物理层的初始设定，例如与另一数据传输装置等的时钟同步，并进行数据链路层的初始化处理，从而进行后续的数据发送和接收启用。也就是说，即使在某一部分不可能发送和接收的情况下，环形LAN中配置的数据传输系统也能够使用除损坏点之外的传输线进行通信。

摘要： A data section is mapped such that the polarity of the signal level of each symbol is constantly inverted on a symbol by symbol basis. On the other hand, a header section is mapped such that the header section includes a distinguishing symbol for distinguishing the data section and the header section from each other, and such that the signal level of the distinguishing symbol is equal to the signal level of the symbol which is mapped immediately before the distinguishing symbol. Thus, data transfer, by which the header section and the data section can be distinguished from each other with certainty by an apparatus on the receiving side, is made possible.

摘要： A data transmission apparatus 10 for transmitting a data signal in accordance with a predetermined protocol in one direction within a ring network of a plurality of data transmission apparatuses includes: signal determination means 11 for determining a presence or absence of a data signal from an immediately upstream data transmission apparatus 10 in the ring network based on an amplitude of the data signal; and stopping means for stopping transmission of the data signal to an immediately downstream data transmission apparatus 10 if the signal determination means 11 determines that there is no incoming data signal. The data signal is a signal obtained by modulating an amplitude component of an electrical signal of a predetermined frequency. Thus, a data transmission apparatus is provided which can quickly detect a momentary power interruption in a data transmission system composed of data transmission apparatuses interconnected in a ring fashion.

摘要： A communications system and a communications device are provided that can reduce the difference in data reaching time with a simple structure and can play audio without making listeners feeling strange. A communications device 105 is coupled to a network 101 and a device 106 such as a CD player or the like. The communications device 105 includes a network interface unit 100, a network controller 103 communicating with the device 106 and others, and a CPU controlling these components. Furthermore, the network interface unit 100, a transmission signal processing unit 107 and a reception signal processing unit 108 converts the data format appropriate for the network controller 103 and the network 101, respectively. A transmission scheme determination unit 102 determines the transmission scheme used among nodes. First and second switches 109 and 110 each have a contact A and a contact B, connecting either one of these contacts based on a control signal from the transmission scheme determination unit 102.

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.
