Method for providing interactive services
It is provided a method for providing an interactive service. At the side of a device among a plurality of devices, each being assigned one of two types, the method comprises the steps of receiving a first request associated with the interactive service requesting for responses associated with the interactive service, wherein the first request includes conditional information associated with the devices; and in response to an input from a user, if said device is of a first type, sending the response; and if said device is of a second type, sending the response only if the device meets the conditional information included in the first request.
1. A method, performed by a receiver device configured to receive interactive services, comprising:
determining, by the receiver device, if the receiver device is of a first type or if the receiver device is of a second type, wherein the receiver device that has determined that it is of the first type is allowed to always send a response to a request received with an interactive service, the request comprising conditional information, while the receiver device that has determined that it is of the second type is allowed to send a response to said request only when the receiver device has determined that it meets a condition indicated by said conditional information;
receiving, by the receiver device, a first request associated with the interactive service, the first request requesting for a response associated with the interactive service, the first request includes conditional information identifying a group of receiver devices; and
in response to user input, when the receiver device has determined that it is of the first type, sending, by the receiver device, a response based on the user input; and when the receiver device has determined that it is of the second type, sending, by the receiver device, the response only when the receiver device has determined that it meets the condition indicated in said conditional information comprised in the first request.
2. The method according to claim 1 , wherein, when the receiver device has determined that it is of the second type and the receiver device has determined that it does not meet the condition indicated in the conditional information comprised in the first request, the method further comprises storing the response in the receiver device.
3. The method according to claim 2 , wherein, when the receiver device has determined that it is of the second type and the receiver device has determined that it does not meet the condition indicated by said conditional information comprised in the first request, the method further comprises:
receiving a broadcast request associated with the interactive service including second conditional information different from the conditional information comprised in the first request; and
sending the stored response when the receiver device has determined that it meets the condition indicated in the second conditional information comprised in the broadcast request.
4. The method according to claim 2 , wherein, when the receiver device does not receive user input responsive to receipt of the first request, the method further comprises:
determining whether a response has been stored responsive to a previous request that is the same as the first request; and
sending the stored response only when the receiver device has determined that the condition indicated in the conditional information comprised in the first request is met.
5. The method according to claim 1 , further comprising changing, by the receiver device, the type of the receiver device between the first type and the second type based on statistics of previous responses sent by the receiver device.
6. The method according to claim 5 , wherein, the statistics of previous responses comprise an average number of responses sent by the receiver device during a program or in a day.
7. The method according to claim 6 , wherein, when the average number is above a value, the receiver device is determined to be of the first type, otherwise it is of the second type.
8. The method according to claim 1 , wherein the conditional information includes information about receiver device identifier, location and idle time.
