摘要： The present invention makes it possible to efficiently transmit data for statistical multiplexing which is required for control using statistical multiplexing. By utilizing private packets, respective encoding devices transmit encoding difficulties serving as the data for statistical multiplexing to a multiplexer (4) via the same transmission channels as encoded video data and audio data are transmitted. The multiplexer (4) conducts multiplexing processing on data supplied from the respective encoding devices at a first rate R1 larger than a transmission rate on a transmission channel of a subsequent stage, and outputs a transport stream (TSd including the private packets to a statistical multiplexing computer. In addition, the multiplexer (4) conducts multiplexing processing on data obtained by removing the private packets, at a second rate R2 which is equal to the transmission rate on the transmission channel of the subsequent stage, and outputs a transport stream (TSm) which does not include the private packets to the transmission channel of the subsequent stage.

摘要： The present invention is an apparatus and method to remove delay fluctuations generated on a plurality of networks.A reception apparatus 22 receives ATM cells transmitted through a network 4-1 and a network 4-2, converting the cells into a transport stream. At that time, the reception apparatus 22 expresses a PCR packet's timing of arrival at the reception apparatus 22 by a count value obtained as a result of counting the number of clock pulses (clock pulses Nr) synchronous with a network clock signal of the network 4-2. The reception apparatus 22 also computes a new PCR value W on the basis of the count value and the phase-difference information used as synchronization information. The reception apparatus 22 then computes a new PCR value X on the basis of an original PCR value E recorded from the beginning on the encoding side and the PCR value W, newly recording the PCR value X.

摘要： 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.

摘要： A digital video data recording system has a signal source, a motion detector, an external memory for storing motion vector data, an encoder, a recorder, and a controller. The controller obtains motion vector data and quantization step size data in a preprocessing procedure, and encodes image data using the motion vector data read from the external memory and the quantization step size data and records the encoded image information on a recording medium in a recording process. The digital video data recording system can encode image information appropriately depending on the type of the image information, minimizes the consumption of electric energy by not effecting a motion detecting process in the recording process, and can record all the image information to be recorded on the recording medium.

摘要： 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.
摘要翻译：同步信息表示PCR值E和计数器值N（= 3240000）之间的差（β），如果假设第三PCR分组在时间（时间t1）到达发送装置201，则计数值N变为3240000 基于PCR值E3和计数值N3之间的差（α），同时计数与（计数值N3-参考时钟值B）一样多的时钟。因此，可以消除网络上产生的延迟波动。
