摘要： A communication system includes a server that receives broadcast data and outputs the received data to a network-connected client and a client that performs reproduction or recording of the data received from the server. The server includes a broadcast receiving unit that receives the broadcast data and a server-record-scheduling-information managing unit that creates a record scheduling list. The client includes a client-record-scheduling-information managing unit that acquires the record scheduling list from the server and a record processing unit that executes an acquisition request for record-scheduled contents. The server-record-scheduling-information managing unit receives content acquisition request data from the network-connected client, selects request data from plural content acquisition request data overlapping in time, performs a content transmission permission response as a response to the selected request data and transmits requested contents, and performs a response indicating that a request is not executed as a response to the request data not selected.

摘要： A communication processing apparatus that acts as a server for transmitting data to a client includes a data transceiver configured to carry out communications with the client; a rate controller configured to control a bitrate of data transmitted to the client; and a data processor configured to prepare data to transmit in accordance with the bitrate. The rate controller includes a throughput calculator configured to extract an effective data transmission and reception period not including an ineffective data transmission and reception period in a period during which a communication connection is maintained between the server and the client, and to calculate a maximum throughput on the basis of the length of the effective data transmission and reception period and the amount of data transmitted; and a bitrate setter configured to set a bitrate within a range of up to a maximum allowable bitrate corresponding to the maximum throughput calculated by the throughput calculator.
