Each of multiple cameras encodes and transmits a video signal captured, the encoding being performed with one of multiple variable bit rate encoding schemes each of which has a different average bit rate. A receiving device periodically measures the total bandwidth of the video signals received from the multiple cameras, and when the total bandwidth exceeds a first threshold value the receiving device switches the encoding scheme used by the cameras to a scheme having a lower average bit rate. In addition, when the total bandwidth falls below a second threshold value that is equal to or less than the first threshold value, the receiving device switches the encoding scheme used by the cameras to a scheme having a higher average bit rate.

Camera system

A transmitting section of the present invention initiates transmission of a second video continuously after completing transmission of a first video being transmitted, in a case that a reproduction position of the first video being transmitted is beyond an end point of the first video, when a video recording start time of a second video stored in a video storage section and a video recording end time of the first video being transmitted coincide within a predetermined time difference.

Time-shifted viewing system, time-shifted viewing method, and time-shifted viewing apparatus and program

A base server apparatus of the present invention includes a data distribution control unit for receiving a pause request signal that requests to pause playing the data from a terminal, and a data accumulation unit for starting to record data transmitted from a distribution center after receiving the pause request signal. The data distribution control unit includes a distribution unit that transfers the data transmitted from the distribution center to the terminal not requesting to pause playing the data, and if a resume request signal requesting to resume playing the data is received from the terminal requesting to pause playing the data, the distribution unit distributes the data recorded in the data accumulation unit to the terminal.

Base server apparatus, communication method, communication control program, distribution system, and communication system

A data receiving device which comprises a decoder which generates a plurality of decoded data based on 1) input data and 2) a plurality of pairs of control data and redundant data, in each the pair, the control data defining a selected encoding process and the redundant data being generated by the selected encoding process based on the control data and the input data, a selection control part which generates an error occurrence information based on information obtained from a medium through which the input data is received, and a selection part which selects output data from the input data and the plurality of decoded data based on the error occurrence information.
