" a replacing " key is provided in the embodiment of the invention, and the user by reading signal source or channel information, judges that the signal source or the channel record information that are read have or not renewal, thereby switches to echo signal source or channel easily by " replacing " key the time.
Consult Fig. 4, the method flow diagram of the quick switching signal source that the embodiment of the invention provides, details are as follows.
Step S401 receives input instruction.
The user is by pressing the button on remote controller or other human-computer interaction devices, for example, " switching " key and " replace " key etc., corresponding receiving system reception push button signalling, and be decoded into corresponding input instruction.Therefore, in embodiment provided by the invention, the corresponding input instruction of button operation, for example, and by " switching " key, corresponding " switching " instruction; By " replacing " key, corresponding " replacing " instruction, the rest may be inferred by analogy.
Step S402 judges whether the instruction of input is " switching " instruction.
In embodiment provided by the invention, channel that " switching " instruction shows that the user need be after current channel or signal source switch to current channel or signal source or signal source, that is, and echo signal source or channel; " replace " instruction and show that the user need switch to channel or signal source before current channel or the signal source from current channel or signal source, that is, and source signal source or channel.
Step S403 when the instruction of input is " switching " instruction, switches to echo signal source or channel.
Step S404 upgrades the recorded information switch to residing signal source before echo signal source or the channel or channel.
Recorded information can be the address of signal source or channel.As one embodiment of the invention, before input " switching " is not instructed, the address mark of signal source or channel is " 0 ", after " switching " action takes place, promptly, when receiving " switching " instruction, the address mark of residing signal source or channel is " 1 " before switching, and all the other signal sources or channel address are labeled as " 0 "; Perhaps, before input " switching " is not instructed, the address mark of signal source or channel is " 1 ", after " switching " action takes place, that is when, receiving " switching " instruction, the address mark of residing signal source or channel is " 0 " before switching, all the other signal sources or channel address are labeled as " 1 ", and so, the recorded information step of residing signal source or channel was finished before renewal was switched.
As an alternative embodiment of the invention, after " switching " action takes place, described current demand signal source or channel information are recorded as source signal source or source channel in the described recorded information, echo signal source or target channel when this source signal source or source channel are " replacing " action generation, " record " process is exactly the recorded information process in update signal source.
Step S405 judges whether the instruction of input is " replacing " instruction.
As previously mentioned, " replacing " instruction receives " replacing " push button signalling for receiving system, and is decoded into corresponding input instruction.

Step S407 reads the recorded information of signal source or channel.
In embodiment provided by the invention, the recorded information of signal source or channel can be stored in electricity erasable memorizer E2PROM, signal source that is read or channel comprise switch before residing signal source or channel and removing switch other signal sources signal source of living in before or the channel or the recorded information of channel.Because the operation of switching channels and switching signal source can not be carried out simultaneously, channel that recorded information has been upgraded or signal source can only be one that switches in residing channel before target channel or the signal source or the signal source.When recorded information was the address of signal source or channel, this recorded information can only be the combination of the combination of " 0 " and several " 1 ", " 1 " and several " 0 ", complete " 0 " combination or complete " 1 " combination.Obviously, when recorded information was complete " 0 " combination or complete " 1 " combination, recorded information was not upgraded, and the user does not carry out handover operation.
Step S408, the recorded information whether signal source that judgement is read or channel have renewal.
Whether the foundation of judging is in the recorded information of the signal source that read or channel, have a recorded information different with other recorded information.For example, in embodiment provided by the invention, when recorded information is the combination of the combination of " 0 " and several " 1 " or " 1 " and several " 0 ", then show the recorded information that the signal source that read or channel have renewal, process skips to step S409.
Step S409 switches to signal source or channel that recorded information has been upgraded.
With recorded information is that the address of signal source or channel is an example, when recorded information is the combination of the combination of " 0 " and several " 1 " or " 1 " and several " 0 ", show that then the user used " switching " key, and this moment input " replace " instruction makes system switch to current demand signal source or channel residing signal source or channel before.
Step S410 keeps current demand signal source or channel.
When recorded information is not upgraded, that is, in an embodiment provided by the invention, when the signal source that is read or the recorded information of channel make up for complete " 0 " or make up " 1 " entirely, then response is not done in " replacing " instruction of input, kept current demand signal source or channel.For example, the user presses " replacing " key when exchanging start or standby start, because system does not receive " switching " instruction before this, the user does not carry out " switching " operation behavior, system's impossible " switching " is residing signal source or channel to the current demand signal source or before the channel, therefore can only keep current demand signal source or channel.
