Abstract: Even the case where the transmission rate for packets is varied in forming a sequence of packets from the packets, time information previously added to each packet is corrected based on absolute time information added to each of the packets forming the sequence of packets, thereby making it possible to realize a data processing apparatus and method capable of significantly improving the transmission efficiency for packetized data.

Abstract: An information transmitter includes a signal separator for separating a packet line multiplexed by another transmitting device into a packet line of element data and a packet line of second additional information on the element data; an additional information generator for generating third additional information integrated by combining and regenerating the second additional information and first additional information; and a controller for controlling packet identifiers which are added at encoders and instructing a plurality of encoding to add packet identifiers that are different from each other. Thus, the overlaps of additional information and packet identifier information can be easily avoided with a simple construction.

Abstract: Synchronous information indicates a difference (&bgr;) between a PCR value E and a counter value N (=3240000), if the third PCR packet is assumed to arrive at a transmitting apparatus 201 at the time (time t1) the count value N becomes 3240000, on the basis of a difference (&agr;) between the PCR value E3 and the count value N3, both generated while as many clocks as (count value N3—reference clock value B) are being counted. Hence, the delay fluctuation generated on a network can be eliminated.

Hence, the delay fluctuation generated on a network can be eliminated.

Abstract: A digital video signal is transmitted via a communication system which can transmit digital data through an asynchronous communication line (ATM communication line) or the like and, at the same time, voice information for the working communication and information such as computer information are transmitted by using the communication system. The user of a first data transmitting apparatus sets up the character data etc. for communication on the terminal. The set character data is multiplexed in the predetermined transmission packet together with the audio and video data output from the VTR device and transmitted via an ATM communication line 2 to a second data transmitting apparatus. In the second data transmitting apparatus, the character data is demultiplexed from the transmission packet and displayed on for example the display device of the personal computer. In place of the character information, also voice information can be transmitted by a telephone set.

Abstract: A data transmitting method, a data transmitting apparatus, and a data transmitting system by which a transmission delay time to be received by the transmission data is measured, the data is transmitted while compensating for the transmission delay in the communication line on the transmission side, and the data received at the reception side is processed. The transmitting apparatus on the reception side transmits the measurement bit to the transmission side, and the transmission side sends back this measurement bit to the reception side. The delay processing circuit on the reception side detects the time difference between the generated measurement bit and the returned measurement bit. The delay processing circuit on the reception side generates the reference signal at a timing preceding in time the reference signal in the internal portion on the reception side by exactly the detected time difference and transmits the same to the transmission side.

Abstract: A data transmission method for transferring predetermined transmission data between a slave side and a master side to which the predetermined transmission data is transmitted and which are connected through a predetermined communications network, wherein the master side generates an independent synchronization clock signal and transmits synchronization data showing the frequency of the independent synchronization clock signal to the slave side, the slave side generates a slaved synchronization clock signal synchronized with the synchronization clock signal of the master side based on the synchronization data transmitted from the master side and generates the transmission data and transmits it to the master side in synchronization with the generated slaved synchronization clock signal, and the master side receives the transmission data transmitted from the slave side in synchronization with the independent synchronization clock signal.

Abstract: A substrate bias generator for supplying a predetermined substrate bias voltage to a semiconductor device includes a charge circuit in which there is provided a rectifying pMOS transistor formed in an n-well. The n-well is maintained at a negative voltage level during the pumping operation. As a result, the threshold voltage of the rectifying pMOS transistor is prevented from increasing to enable the bias volatge to be supplied at a higher efficiency.
