Reception device, station selection method, and stream distribution system
First Claim
1. A receiving apparatus which can switch and receive a television broadcast and stream data, comprising:
- reproducing means for reproducing the received stream data;
switching means for switching an input between an input from said reproducing means and another input; and
communicating means for communicating with a transmitting source of said stream data, wherein in the case where said input is switched from the input from said reproducing means to said another input by said switching means during the reproduction of said stream data by said reproducing means, a stop request to stop transmission of said stream data is transmitted to the transmitting source of said stream data by said communicating means, and in the case where said input is switched again from said another input to an output from said reproducing means by said switching means, a start request to start the reproduction of said stream data from a position where the transmission of said stream data has been stopped is transmitted to said transmitting source of said stream data by said communicating means.

Abstract
When an input is switched to another input during monitoring of stream data and the input is returned to the stream data again, the stream data can be easily reproduced from a position just before it is switched to another input. When the input is switched to a DTV broadcast received by an antenna 2 during the reproduction of a video stream transmitted from a video server 10, a receiver 1 requests the video server 10 to stop the reproduction of the video stream and stores information of a position where the reproduction of the video stream is stopped. In the receiver 1, when the input is switched to the video stream side again, the receiver 1 requests the video server 10 to restart the reproduction of the video stream which had been reproduced just before the input has been switched at the previous time. At this time, the position information stored upon transmission of the reproduction stop request is transmitted to the video server 10 and the reproduction of the video stream is started from the position where the input has been switched at the previous time.

10. A station selecting method which can switch and receive a television broadcast and stream data, comprising the steps of:
-
reproducing the received stream data;
switching an input between an input from said reproducing step and another input; and
communicating with a transmitting source of said stream data, wherein in the case where said input is switched from the input from said reproducing step to said another input by said switching step during the reproduction of said stream data by said reproducing step, a stop request to stop transmission of said stream data is transmitted to the transmitting source of said stream data by said communicating step, and in the case where said input is switched again from said another input to an output from said reproducing step by said switching step, a start request to start the reproduction of said stream data from a position where the transmission of said stream data has been stopped is transmitted to said transmitting source of said stream data by said communicating step.

11. A stream distribution system for distributing stream data to a receiving apparatus which can switch and receive a television broadcast and the stream data, comprising:
-
a stream data server for reproducing and transmitting the stream data; and
the receiving apparatus having reproducing means for receiving said stream data transmitted from said stream data server and reproducing said received stream data, switching means for switching an input between an input from said reproducing means and another input, and communicating means for communicating with said stream data server, wherein in the case where said input is switched from the input from said reproducing means to said another input by said switching means during the reproduction of said stream data by said reproducing means, said receiving apparatus transmits a stop request to stop the transmission of said stream data to said stream data server by said communicating means, said stream data server stops the transmission of said stream data by said stream data server in accordance with said stop request, in the case where said input is switched again from said another input to the input from said reproducing means by said switching means, said receiving apparatus transmits a start request to start the reproduction of said stream data from a position where the transmission of said stream data has been stopped to said stream data server by said communicating means, and said stream data server reproduces said stream data from the position where the transmission of said stream data has been stopped and transmits said stream data to said receiving apparatus in accordance with said start request. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
