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： A transmission side of a communication apparatus of the present invention makes use of a clock signal synchronized with a network to transmit an arrival interval of a PCR packet in which a PCR value is included and a synchronization residual. A reception side of the communication apparatus of the present invention calculates delay fluctuations caused by the network from the arrival interval and the synchronization residual included in the received PCR packet and modifies the PCR value based on the delay fluctuations.

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： Disclosed is a network game system in which a time lag is adjusted, using game terminal type information such as its ID number. A network game server comprises a lag adjusting program and a database to be referenced to execute the lag adjusting program. On the network, data from game terminals is transmitted in packets to the network game server where concentrated management is made of all packet data as user information. Different transmission time lags predetermined for the product types of the game terminals that are expected to connect to the server are stored into the database beforehand. When the server receives packet data from a terminal device having an EUI-64 identifier, the appropriate transmission time lag is read, based on the identifying information.

摘要： A system allows data transfer in which the most appropriate packet processing is executed according to the performance of a terminal. A data transmission side stores scalable-encoded data in a packet as a payload, assigns priority-level information corresponding to a layer level of the encoded data stored in the packet to a packet header, and transmits the packet. A data receiving side performs processing by referring to the priority-level information. A level of priority dependent on an application is specified in an RTP payload header according to the degree of importance of scalable-encoded data, and a level of priority is further specified in an IP header. The most appropriate packet processing based on the performance of a terminal is allowed. Re-transmission control based on the layer level of encoded data is also allowed.

摘要： The present invention relates to a moving-picture distribution system, a moving-picture distribution apparatus and method, a recording medium and a program capable of distributing a picture having different qualities at the same time to a plurality of users specifying the different qualities. In the moving-picture distribution apparatus, a data-encoding unit 42 performs layered encoding on the moving picture in frame units on the basis of a first quality, storing an encoded frame in a first buffer 43a, and performs layered encoding on the moving picture in frame units on the basis of a second quality, storing an encoded frame in a second buffer 43b. A packet generation unit 44 packetizes the frame stored in the first buffer 43a to generate a first packet group and packetizes the frame stored in the second buffer 43b to generate a second packet group. A communication unit 45 transmits selected packets of the first and second packet groups to a network 13a. The present invention can be applied to a moving-picture distribution system for distributing moving-picture data.
