<p>The present invention aims at reducing the power consumption of a receiver/decoder connected to a broadcast channel. It is proposed a method to manage the power setting of a receiver/decoder for pay-TV comprising a timer and means to receive management messages, the power setting comprising at least three states, the active state during which the reception and the decoder is active, the active/standby state during which the receiver is active for the reception of management messages and the standby state during which the receiver/decoder is in idle mode, said method comprising the steps of :
- receiving a first management message enabling an update mode during which the receiver/decoder is updated,
- receiving a second management message canceling the update mode and containing a first period, said period being loaded into the timer and defining the period during which no new management messages is awaited,
- receiving a request from a user to pass from the active state to the standby state,
- determining if the update mode is active :
- in the positive event
- changing the power setting into active/standby state,
- waiting until the second management message is received, at reception of same the power setting into standby state,
- in the negative event, determining by the timer if the first period is not terminated :
in the positive event, changing the power setting into standby state;
in the negative event, changing the power setting into active/standby state, waiting until the first management message is received, at reception of same, enabling the update mode.</p> |
