  • Patent number: 8185661
    Abstract: A packet compressor 12 operates under a reliable mode or an optimistic mode. A mode determination unit 31 counts the number of ACK packets or NACK packets received by a unit time X by an ACK/NACK packet receiver 14. When the counted number of NACK packets is larger than a predetermined value Y, the mode determination unit 31 switches the operation mode of the packet compressor 12 to the reliable mode. When the counted number of ACK packets is larger than a predetermined value Z, the mode determination unit 31 switches the operation mode of the packet compressor 12 to the optimistic mode.

  • Patent number: 8020140
    Abstract: According to the media server 100 and the network control apparatus 200, upon distributing a plurality of media data to the media receiving apparatuses 400 having different transmission rates by broadcasting or multicasting, the distribution precedence is attached by associating the program control information and the media data. The distribution precedence attached to the program control information is set same as or lower than the distribution precedence of all media data included in the program concerned. Then, depending on the distribution precedence, the transmission possible media data and the program only are selectively distributed. The program control information relating to the program that includes the receivable media data by the media receiving terminal apparatus 400 only is selected and received. This way, the receivable media data is distributed depending on the transmission environment of the media receiving apparatus.

  • Patent number: 8014792
    Abstract: A distance between positional information added to contents and a current position detected in an information receiving terminal is calculated, and based on the calculated distance, a method for outputting the contents is controlled. Thus, since the method for outputting the contents can be changed by a positional relationship between the contents and the information receiving terminal, distance relationship between the current position and the contents can be clearly displayed so that users can easily select the contents.

  • Patent number: 7801182
    Abstract: Information relating to a playback of divided static media data included in static media transmission data is stored in static media transmission data previous than the static media transmission data, and transmitted, thereby making it possible to determine whether there is no divided static media data originally or lost when the divided static media data is not received. Accordingly, in the case where static media such as timed text and the like is used in distribution of streaming type, when receiving no static media data, a data receiving apparatus determines whether there is no media data to be next displayed or media data is lost in the course of transmission to notify a user of loss of media data correctly. Moreover, it is possible to reduce time required for packet loss detection to execute a retransmission request without increasing pre-buffering.

  • Publication number: 20100197316
    Abstract: A radio communication terminal capable of efficiently performing DRX or DTX. The terminal comprises an on-period determining section (106) and a DRX/DTX control section (108). The on-period determining section (106) determines a subframe at the beginning of a first on-period within a DRX period by matching it with the subframe during which a CQI report is performed, determines the subframe apart by an integral multiple of the DRX cycle from the determined subframe at the beginning of the first on-period as the subframe at the beginning of the first on-period, and determines the subframes within the first on-period including each sub frame at the beginning of the first on-period as those in an on-period state. The DRX/DTX control section (108) controls the DRX of a receiving section (101) and the DTX of a transmitting section (109) according to the subframe in an on-period state inputted from the on-period determining section (106).

  • Patent number: 7392322
    Abstract: The radio control section 205 notifies a transmission rate that can be currently set up out of the radio channel transmission rates to the transmission rate decision section 207. The buffer monitoring section 208 monitors an amount of media data stored in the media reception buffer 209 and when the amount of media data stored exceeds a threshold, the buffer monitoring section 208 notifies it to the transmission rate decision section 207. When information on the radio channel transmission rate from the radio control section 205 shows that the radio channel transmission rate is well within the capacity and when monitoring information from the buffer monitoring section 208 shows that the amount of data stored in the media reception buffer 209 does not exceed a threshold, the transmission rate decision section 207 outputs a request for increasing the transmission rate of the media data to the control signal transmission/reception section 206.

  • Patent number: 7296081
    Abstract: Without RTP receiver 106 receiving a BYE packet, end time determiner 111 takes into consideration packet loss information from packet loss monitor 110 and the situation regarding RTP packet reception from RTP receiver 106, and determines media transmission from the server is completed, and instructs control command transmitter-receiver 109 to stop the media, provided that the situation where there has been no packet loss and no RTP packet has been received. Moreover, where RTP receiver 106 does not receive data, the end of media is not determined if a packet loss has occurred in a lower layer.

  • Patent number: 7295575
    Abstract: A packet transmission apparatus and method may divide data into a plurality of packets and transmit the packets. At a transmitting end, a context identifying number, identifying a data stream, is selected based on a relationship between a sequence number of a packet that is to be transmitted and a sequence number in an immediately preceding packet. A sequence number denoting an order of a packet divided on a per context basis is compressed, and transmission data assigned to the context identifying number with the compressed sequence number is transmitted on a per packet basis. At the receiving end, the compressed sequence number is decompressed on a per context basis. The context is separated based on the context identifying number, and data is combined by reassembling a packet into the order of a decompressed sequence number.

  • Patent number: RE43100
    Abstract: In a header decompression apparatus 709, a header decompressor 703 refers to reference information stored in a reference information manager 707 to decompress a compressed header of a packet received by a packet receiver 704. An error detector 702 detects a CRC error in the packet with its header decompressed by the packet receiver 704, and outputs only a correct packet. A successive error counter 705 counts the number of successive errors detected by the error detector 702. A successive decompression success counter 706 counts the number of decompression successes that successively appear. By referring to these counted numbers, an update request unit 708 transmits an update request to a transmitting side as required. The reference information manager 707 manages the reference information for header decompression. With this structure, the header decompression apparatus can request update of the reference information based on the state of the error.
