1. A receiving apparatus comprising:
- an instruction input unit for input of an instruction to receive data externally;
a data input unit for input of first service data and second service data to be externally sent in accordance with the instruction of said instruction input unit; and
a control unit operative to perform control and processing of the data as input to said data input unit, whereinin a case where an instruction to receive the second service data is input to said instruction input unit while said control unit is processing the first service data being input to said data input unit in accordance with the instruction as input to said instruction input unit, when said control unit determines that the processing of the second service data becomes slower to an extent that is equal to or more than a predetermined degree as a result of said control unit'"'"'s simultaneous execution of the processing of the first service data and the reception of the second service data, said control unit performs processing of the second service data with priority being given thereto.

Abstract
A receiver apparatus capable of retaining the quality of video images received through complexity-reduced small-load processing without having to depend upon its associated transmitter device. In cases where an instruction is made for receiving streaming data in the process of performing the processing of download data, when the loss of such streaming data is predicted to increase in such a way as to go beyond a predetermined degree if both the processing of download data and the processing of streaming data are performed at a time, the receiver performs the processing of the streaming data by giving thereto a higher level of priority.

3. A receiving apparatus comprising:
-
an instruction input unit for input of an instruction to receive data externally; a data input unit for inputting externally transmitted download data and streaming data; and a control unit for performing control and processing of the data as input to said data input unit, wherein in case an instruction to receive the streaming data is input to said instruction input unit while said control unit is processing the download data being input to said data input unit in accordance with the instruction as input to said instruction input unit, when said control unit determines that a loss of streaming data becomes larger to an extent that is equal to or more than a prespecified degree as a result of said control unit'"'"'s simultaneous execution of reception of the download data and reception of the streaming data, said control unit interrupts the reception of the download data and performs the reception and processing of the streaming data. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A receiving apparatus comprising:
-
an instruction input unit for input of an instruction to receive data externally; a data input unit for receiving externally transmitted download data and streaming data; and a control unit for performing control and processing of the data as input to said data input unit, wherein in case an instruction to receive the streaming data is input to said instruction input unit while said control unit is receiving the download data being input to said data input unit in accordance with the instruction as input to said instruction input unit, when said control unit determines that a loss of streaming data becomes larger to an extent that is equal to or more than a prespecified degree as a result of said control unit'"'"'s simultaneous execution of reception of the download data and reception of the streaming data, said control unit reduces a download rate and performs simultaneous reception of the download data and the streaming data along with processing thereof. - View Dependent Claims (14, 15, 16, 17)

18. A receiving system comprising:
-
a first receiver device including a first instruction input unit for input of an instruction to receive externally incoming data, a first data input unit for input of download data and streaming data to be externally transmitted in accordance with the instruction of said first instruction input unit, and a first control unit for performing control and processing of the data being input to said first data input unit; and a second receiver device having a second instruction input unit for input of an instruction to receive externally incoming data, a second data input unit for input of download data and streaming data to be externally sent forth in accordance with the instruction of said second instruction input unit, and a second control unit for performing control and processing of the data as input to said second data input unit, wherein in a case where an instruction to receive the streaming data is input to said second instruction input unit while the first receiver is processing service data being input to said first data input unit by said first control unit, when said second control unit of the second receiver determines that a loss of streaming data becomes larger by a prespecified degree or more as a result of execution of reception of the streaming data, said second receiver performs the reception and processing of the streaming data with priority being given thereto.
