Method for saving power in radio frequency (rf) receiver and rf receiver
First Claim
1. A method for controlling power consumption in a radio receiver for receiving transport stream packets, wherein selected transport stream packets are transferred to said receiver in predetermined order, comprising the steps, where:
- power of at least part of the receiver is turned off for a period during the time between at least two selected transport stream packets, and said receiver is informed about when to receive at least one of the following selected transport stream packets.

Abstract
The invention relates generally to a method and an arrangement (600) for reducing power consumption and an RF transmission arrangement and RF receiver. Particularly the invention relates to controlling and reducing power consumption in a radio receiver. The essential idea of the invention is to insert information to at least one symbol, which symbol is transferred in at least one transport stream packet. According to the invention the transport stream packets are sent to the receiver in predetermined order, and the order is informed to the receiver, whereupon the receiver can control power consumption with a transport stream packet level resolution. The receiver is advantageously arranged so that at least part of the receiver is turned off for a period during the time between receiving at least two transport stream packets. The invention may advantageously be applied in receiving arrangements of radio systems, wherein information is transferred in packets, such as a receiver of Digital Video Broadcasting (DVB) system.
