Abstract: Disclosed is a mobile communication system preventing the transmission of acknowledgements at a burst leading to a decrease in throughput caused by detecting the retransmission and the congestion of packets at the protocol of a transport layer. In a mobile communication system including a mobile terminal and gateway equipment for relaying a packet between a communication partner and the mobile terminal, if the gateway equipment receives the acknowledgement from the mobile terminal, the gateway equipment waits the transmission of the received acknowledgement to the communication partner until the estimated transmission time passes from the time at which the gateway equipment receives the previous acknowledgement from the mobile terminal.

Abstract: A name and a URL of a specific link destination are stored in a specific link destination information storing section. A microcomputer changes a process to be performed on a link destination depending on whether or not a link destination targeted for the process is a specific link destination. The specific link destination is highlighted when displaying link destinations as icons, and the specific link destination is displayed first when displaying a list of the link destinations. An access history about the specific link destination is stored in an access history storing section. An information server collects the access history from a television receiver and counts the number of accesses to the specific link destination. When the advertisement site is selected as the specific link destination, the number of accesses to the specific link destination is used as an index for indicating an advertising effect.

Abstract: A transmitting party adds reproduction time information to each transport packet to form an extended transport packet, encapsulates the extended transport packet, adds capsule counter information, and transmits the capsule. A receiving party has a storage means, and transmits a re-send request including the capsule count information to the transmitting party when a packet loss occurs. At the receiving party, the re-sent data received overwrites data in its original storage region. At reproduction, the receiving party decodes the data after compensating for jitter referring to reproduction time information. Accordingly, a packet loss or jitter is compensated for at both transmitting and receiving parties in a communications network such as the Internet so as to prevent the occurrence of a decoding error at the receiving party.

Abstract: A television receiver (1) acquires numerical quantity information from program list information acquired from a television signal or the like, the acquired numerical quantity indicates the number of program-related information related to a television program and (2) displays the acquired numerical quantity information on a television display screen. When a user selects a television program whose program-related information is to be acquired, the television receiver acquires a URL of program-related information from an address server by utilizing the program identification code of the selected television program, acquires the program-related information from an information server by utilizing the acquired URL, and displays the acquired program-related information so as to be superimposed on a television picture.

Abstract: A broadcasting system comprises a transmission apparatus, which multiplexes stream-format data based on a stream transmission protocol and file-format data based on a file transmission protocol with each other and sends them as a single stream, and receiving apparatuses which receive and temporarily accumulate stream-format data and file-format data which are sent as they are multiplexed with each other, and stream-format data and file-format data are temporarily accumulated as they directly are in the form of a single stream, all or some of file-format data are reproduced later at predetermined timing and accumulated once again as a file.

Abstract: An operation guarantee system includes a decoder circuit, a comparison circuit, a CPU circuit, a frequency adjustment circuit and a DQ adjustment circuit. The comparison circuit compares a test data signal input from the decoder circuit with an expected value data signal input from the exterior, and detects the presence or absence of an output error in the decoder circuit. The CPU circuit controls the frequency adjustment circuit and the DQ adjustment circuit to vary a frequency of a clock signal input to an external memory and a delay amount of the data signal. In addition, the CPU circuit acquires a result of detection of the comparison circuit under various conditions. Then, the CPU circuit determines an appropriate frequency of the clock signal input to the external memory based on a relationship between the various conditions and the presence or absence of the output error.

Abstract: It is provided a mobile communication system comprising base stations, call control servers and access gateways. The call control servers cause a mobile terminal accommodated in one of the control server to transmit the location registration request so that the mobile terminal accommodates in another control server according to a processing amount of control signals.

Abstract: A client signal having a constant bit rate is segmented every a bytes to create code information blocks. The bit rate of the client signal is increased such that the client signal has the code information block and an empty area comprised of b bytes, and the ratio c/a is equal to or higher than 110% to create a code block 3 comprised of c bytes. The code information block in the code block is encoded such that an error correcting code is included therein to have an encoding gain of 6 dB or higher for a bit error ratio of 10?12. Associated check bits are placed in the empty area to eventually generate a super FEC signal.
