Communication method
First Claim
1. A communication method, comprising:
- continuously receiving request information transmitted from an external apparatus on a network interface at a given time interval, the request information requesting associated information about a program being received by the external apparatus on a broadcast signal reception section, the program being transmitted by a second external apparatus;
controlling a polling interval for the request information by transmitting timing specification information used to specify timing for the external apparatus to transmit the request information next along with associated information corresponding to the request information to the external apparatus;
authenticating an authentication session ID received from the external apparatus and, when authentication is permitted, issuing an authentication ticket and transmitting the authentication ticket to the external apparatus; and
receiving a notification from the second external apparatus when transmission of the program begins.

Abstract
A client terminal CT transmits an acquisition request for musical composition information. An associated information provision server KS continuously receives the acquisition request at a given time interval. The associated information provision server KS transmits timing specification information along with the musical composition information corresponding to the acquisition request to the client terminal CT. The timing specification information specifies timing for the client terminal CT to transmit the acquisition request next. The associated information provision server KS controls a polling interval for acquisition requests. In this manner, acquisition requests can be distributed to those transmitted at a given time interval and those received in accordance with the timing specification information. A simple method can be used to prevent acquisition requests from being concentrated on the associated information provision server KS.

1. A communication method, comprising:
-
continuously receiving request information transmitted from an external apparatus on a network interface at a given time interval, the request information requesting associated information about a program being received by the external apparatus on a broadcast signal reception section, the program being transmitted by a second external apparatus; controlling a polling interval for the request information by transmitting timing specification information used to specify timing for the external apparatus to transmit the request information next along with associated information corresponding to the request information to the external apparatus; authenticating an authentication session ID received from the external apparatus and, when authentication is permitted, issuing an authentication ticket and transmitting the authentication ticket to the external apparatus; and receiving a notification from the second external apparatus when transmission of the program begins. - View Dependent Claims (2, 3, 4, 5, 6)

7. A communication method, comprising:
-
transmitting, to a server, on a network interface request information requesting associated information about a program being received on a broadcast signal reception section, the program being transmitted by an external apparatus; receiving associated information corresponding to the request information and timing specification information used to specify timing to transmit the request information next from the server; and determining timing to transmit the request information in accordance with the timing specification information, transmitting an authentication session ID to an authentication server and receiving an authentication ticket from the authentication server, when the authentication server authenticates the authentication session ID and determines that authentication is permitted, wherein the external apparatus notifies the server when transmission of the program begins.

8. A server, comprising:
-
request information reception means for continuously receiving request information transmitted from an external apparatus on a network interface at a given time interval, the request information requesting associated information about a program being received by the external apparatus on a broadcast signal reception section, and the program being transmitted by a second external apparatus; control means for controlling a polling interval for the request information by transmitting timing specification information used to specify timing for the external apparatus to transmit the request information next along with associated information corresponding to the request information to the external apparatus, and reception means for receiving a notification from the second apparatus when transmission of the program begins and receiving an authentication ticket from the external apparatus, the authentication ticket being issued by an authentication server that authenticates an authentication session ID provided to the authentication server by the external apparatus and issues the authentication ticket when authentication is permitted.

9. A communication apparatus to request a given server for intended information, the apparatus comprising:
-
request information transmission means for transmitting, on a network interface, request information requesting associated information about a program being received to the server on a broadcast signal reception section, the program being transmitted by an external apparatus; timing specification information reception means for receiving associated information corresponding to the request information and timing specification information used to specify timing to transmit the request information next from the server; timing determination means for determining timing to transmit the request information in accordance with the timing specification information; means for transmitting an authentication session ID to an authentication server; and means for receiving an authentication ticket from the authentication server, when the authentication server authenticates the authentication session ID and determines that authentication is permitted, wherein the external apparatus notifies the server when transmission of the program begins.

10. A non-transitory computer readable medium encoded thereon with a communication control program which when executed causes an information processing apparatus to:
-
continuously receive on a network interface request information transmitted from an external apparatus at a given time interval, the request information requesting associated information about a program being received by the external apparatus on a broadcast signal reception section, and the program being transmitted by a second external apparatus; control a polling interval for the request information by transmitting timing specification information used to specify timing for the external apparatus to transmit the request information next along with associated information corresponding to the request information to the external apparatus; authenticate an authentication session ID received from the external apparatus and, when authentication is permitted, issue an authentication ticket and transmit the authentication ticket to the exterrnal apparatus, wherein the information processing apparatus receives a notification from the second external apparatus when transmission of the program begins.

11. A non-transitory computer readable medium encoded thereon with a communication control program which when executed causes an information processing apparatus to:
-
transmit on a network interface request information requesting associated information about a program being received to a server on a broadcast signal reception section, the program being transmitted by an external apparatus; receive associated information corresponding to the request information and timing specification information used to specify timing to transmit the request information next from the server; determine timing to transmit the request information in accordance with the timing specification information; transmit an authentication session ID to an authentication server; and receive an authentication ticket from the authentication server, when the authentication server authenticates the authentication session ID and determines that authentication is permitted, wherein the external apparatus notifies the server when transmission of the program begins.
