Fig. 2 is a flowchart of another local time shifting method according to a second embodiment of the present invention, as shown in fig. 2, according to the local time shifting method according to the first embodiment, before 101, the method may further include:
201. and receiving a time-shifting keep-on instruction of a user.
202. And determining the time-shifting channel according to the time-shifting keep-on instruction, and storing the channel identifier of the time-shifting channel.
Specifically, the time shift hold on instruction is used for a user to instruct to turn on a channel of the time shift hold, so that the local device still stores the time shift data of the channel after switching from the channel or when the channel is not played.
In an implementation manner of this embodiment, the determining, in 202, the time-shifted channel according to the time-shift hold-on instruction may specifically include:
and taking the current channel as the time-shifting channel according to the time-shifting keep-on instruction.
The current channel is a channel being played by the local device, that is, a channel being watched by the user. Specifically, the application scenario of this embodiment may be that, when a user watches a program played in a certain channel, the user may want to leave the channel temporarily, perform channel switching to browse programs in other channels, but does not want to miss the watching of the program, and at this time, the user issues a time-shift hold-on instruction while watching the channel, and then switches to an interface of another channel that the user wants to browse. In this scenario, the time-shift hold-on command need not carry a time-shift channel identifier. The transmission method of the program is not limited to Cable television (Cable) transmission, satellite transmission, digital terrestrial broadcasting, network multicasting, or the like.

Further, after the stopping storing the time shift data of the first target channel, the method may further include:
deleting the locally stored time-shifted data of the first target channel.
The local time shifting method provided by this embodiment keeps storing the time shifting data of the time shifting channel in real time after receiving the time shifting keep-on instruction of the user, and continues to store the time shifting data of the time shifting channel in real time when the channel is switched.

receiving a second channel switching instruction of the user;
and acquiring a second target channel identifier according to the second channel switching instruction, switching from the time-shifted channel to a second target channel corresponding to the second target channel identifier, and stopping storing the time-shifted data of the time-shifted channel.
That is, after the time shift holding for the time-shifted channel is turned off, if the time-shifted channel is switched to another channel, the time-shifted data of the time-shifted channel is not stored.
According to the local time shifting method provided by the embodiment, when a time shifting keep-close instruction of a user is received, the stored channel identifier of the time shifting channel is used for switching from the current channel to the time shifting channel, so that the user can conveniently and quickly return to the time shifting channel after switching the channel on the basis that the user can still watch the program played by the channel before switching after switching.
Fig. 4 is a flowchart of another local time shifting method according to a fourth embodiment of the present invention, as shown in fig. 4, according to the local time shifting method according to the first embodiment of the present invention, after the switching to the first target channel corresponding to the first target channel identifier in 102, the method may further include:
