摘要： A data transmitting apparatus and a data receiving apparatus, which are capable of retransmitting a packet even when a retransmission request is made by a client after transmitting a session close notice packet to the client. A session is closed by a session closing means 105 when a predetermined period of time has passed after transmitting the session close notice packet, which is generated by a control command generating means 102 as the session close notice packet, from a packet transmitting means 103 to the client.

摘要： When an update request signal is output from update request signal receiver 108 to compression scheme selector 201, compression scheme selector 201 selects UPDATE_FULLHEADER. However, compression method selector 201, within an RTT after selecting an UPDATE_FULLHEADER, does not select an UPDATE_FULLHEADER again. That is, within an RTT after transmitting an UPDATE_FULLHEADER a packet transmitting apparatus does not transmit an UPDATE_FULLHEADER even upon receiving an update request signal, and selects NON_UPDATE or UPDATE as usual.

摘要： Update request signal generator 107 generates an update request signal when an NG signal is output from CRC section 104 a predetermined number of times, continuously. More specifically, update request signal generator 107 comprises a counter that counts the number of times errors are detected, increments the counter by 1 every time an NG signal is output from CRC section 104, and resets the counter when an OK signal is output from CRC section 104 or every time the value on the counter reaches a predetermined number of times. Then, update request signal generator 107 generates an update request signal when the value on the counter reaches the predetermined number of times.

摘要： In a sending device (100), a fragmenting portion (101) fragments a bit stream according to the predicted relationship of the frames, and the output of the fragmenting portion (101) is allocated to either a TCP (Transmission Control Protocol) or a UDP (User Datagram Protocol) port. In an IP (Internet Protocol) layer, an encrypting portion (102) executes an encryption process only on the port to which bit stream corresponding to the I (Intra) frames is transmitted. In a receiving device (110), a decrypting portion (112) decrypts data on the port to which the bit stream corresponding to the I frames is transmitted, and a reassembling portion (111) restores the data to the original bit stream. This restoration is carried out by lining up the packets in increasing order of TR (Temporal Reference) value. Thus, the amount of time required for encryption and decryption is reduced compared to a case in which encryption is performed on all frames.

摘要： In a bit counter 214, an amount of codes included in one transmission unit is counted; in a significance decision section 217, the amount of codes counted in the bit counter 214 is divided by the number of coded macroblocks included in the one transmission unit to calculate an average amount of codes per one coded macroblocks; and in a threshold comparing section 220, the significance of the pertinent transmission unit is decided by comparing the average amount of codes to the calculated threshold based on a frame rate and a bit rate.

摘要： A data communication system capable of eliminating the retransmission of useless data that is too late for the playback time at the receiving side, and, accordingly, capable of eliminating the wasteful utilization of transmission band. In the system, round-trip time RTT of a packet between the server (data transmitting apparatus) 100 and the terminal apparatus (data receiving apparatus) 200 is calculated, and only when the sum of the round-trip time RTT and present time is less than the playback time of the packet, retransmission request for lost packet which has high priority is made.

摘要： When an error is detected in a received header, in estimating reference information while assuming an error in a packet receiving interval, a header is decompressed using at least one value of another candidate sequence numbers used in correcting an erroneous sequence number, corresponding to a time that elapses between previously receiving a packet correctly and receiving a current packet and to the packet receiving internal. It is thereby possible to increase a possibility of estimating the reference information correctly and suppress the number of discarded packets at a receiving side, while suppressing increases in introduced processing amount in data transmission with header compression.
摘要翻译：当在接收到的报头中检测到错误时，在分组接收间隔中假设出错时估计参考信息时，使用用于校正错误序列号的另一个候选序列号的至少一个值来解压缩报头，对应于时间以前在正确地接收分组并接收当前分组之间经过并且接收到内部分组。由此，能够在抑制通过报头压缩的数据传输中引入的处理量的增加的同时，增加准确地估计参考信息的可能性，并抑制接收侧的丢弃数据包的数量。
