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.

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.

摘要： A Viterbi decoding apparatus for decoding received data by Viterbi decoding comprising a state metric memory circuit, a path memory circuit, and a path decode word decision circuit. The state metric memory circuit stores state metric information obtained by ACS (Adder, Comparator, Selector) processing. The path memory circuit stores path selection information provided by the ACS processing. The path decode word decision circuit weights a plurality of bits with a path decode word of each state according to its degree of likelihood based on state metric information supplied from the state metric memory circuit, cumulatively adding each path decode word obtained by the weighting operation, and comparing a cumulative value obtained by the cumulative adding operation with a preset threshold value to determine decode words. This setup provides sufficiently reliable decode words by a small amount of hardware and in a short processing time to decode, within an average information rate, convolutional codes having information amounting to 30 Mbps or more used in high-definition TV etc.
