Abstract
A device and a method are provided for saving electric power consumed in a digital broadcasting receiver. The device and method includes acquiring information regarding a transmission order of all service channels, calculating a delay relationship between an arbitrarily played service channel and a service channel for switching, and enabling a broadcast receiving unit when the service channel for switching is received.
Claims19
A method for saving power in a digital broadcasting receiver in channel switching of N service channels repeatedly transmitted in a time slicing operation, the method comprising:
- receiving and processing information regarding a K-th service channel among the service channels by enabling a broadcast receiving unit, wherein K and N are natural numbers and K is smaller than N;
- acquiring information regarding a transmission order of the N service channels;
- determining the order of an M-th service channel for switching from the K-th service channel when channel switching is requested, wherein M is a natural number smaller than N;
- and
- performing channel switching by enabling the broadcast receiving unit in the order of the M-th service channel and then receiving and processing information about the M-th service channel.
A system for saving power in a digital broadcasting receiver, the system comprising:
- a broadcast receiving unit for repeatedly receiving and processing information regarding a K-th service channel among N service channels in a time slicing operation, wherein K and N are natural numbers and K is smaller than N;
- a key input unit for transferring a request for channel switching to an M-th service channel, wherein M is a natural number smaller than N;
- and
- a control unit for acquiring information regarding the transmission order of the N service channels, determining the order of the M-th service channel from the K-th service channel when the channel switching is requested and enabling the broadcast receiving unit when the M-th service channel is received.
