Abstract: There is provided a radio communication apparatus including a detection unit to detect first redundant information indicating redundancy at a physical/MAC layer of radio communication, a communication control unit to determine a second redundancy at an upper layer from the layer based on the first redundant information detected by the detection unit, a packetizing unit to generate a data packet by packetizing transmission data, and a redundant encoding unit to add a redundant packet to the data packet generated by the packetizing unit based on the second redundancy determined by the communication control unit.

Abstract: There is provided a transmission rate control method. In this method, data is transmitted to a receiver at the most recent transmission rate RSNDt?1, and an RTCP packet including a reception rate RRCVt of the data is received from the receiver. When a network is in a congestion state, or when the network is in a non-congestion state and the most recent reception achievement rate RARt?1 is higher than the reception rate RRCVt, a reception achievement rate RARt is calculated as a long-term EWMA of the reception rate RRCV. When the network is in the non-congestion state and the most recent reception achievement rate RARt?1 is lower than the reception rate RRCVt, or when a time-out of the RTCP packet occurs, the reception achievement rate RARt is calculated as a short-term EWMA of the reception rate RRCV. A transmission rate RSNDt is set based on the reception achievement rate RARt.

Abstract: There is provided a transmission rate control method. In this method, data is transmitted to a receiver at the most recent transmission rate RSNDt-1, and an RTCP packet including a reception rate RRCVt of the data is received from the receiver. When a network is in a congestion state, or when the network is in a non-congestion state and the most recent reception achievement rate RARt-1 is higher than the reception rate RRCVt, a reception achievement rate RARt is calculated as a long-term EWMA of the reception rate RRCV. When the network is in the non-congestion state and the most recent reception achievement rate RARt-1 is lower than the reception rate RRCVt, or when a time-out of the RTCP packet occurs, the reception achievement rate RARt is calculated as a short-term EWMA of the reception rate RRCV. A transmission rate RSNDt is set based on the reception achievement rate RARt.

Abstract: A system and method for automatically displaying information from a designated information providing location and information from an associated information providing location. Information a designated information providing location is read from an automatic reading control section through a communication processing section. An information generation section discriminates an associated information providing location included in the read information, generates an automatic reading instruction list for designating a information providing location that reads the next information and stores the automatic reading instruction list in an information storage section. The automatic reading control section sequentially reads information from information providing locations according to the automatic reading instruction list. The information generation section discriminates the associated information providing location included in the read information and updates the automatic reading instruction list.
