In the embodiment of the application, a user can send a first input instruction through a key in a remote controller, and the first input instruction is used for triggering and displaying a recorded recording file list.

It can be understood that the key for calling the recording file list may be a single key dedicated in the remote controller, or may be a combination of multiple keys in the remote controller, which is not specifically limited in this embodiment of the present application.

In response to the first input instruction, the controller may acquire recording information of at least one recording file and configuration data corresponding thereto.

The recording file may be recorded based on a PVR, and in the recording process of the PVR, the recording file such as the recorded video and the like may be encrypted to obtain an encrypted recording file, and the encrypted recording file may be stored in an external device, such as a hard disk, connected through an interface of an external device.

In a specific implementation, the recording mode may include: foreground recording, background recording, time shift recording and the like, and the embodiment of the application does not limit the specific way of obtaining the recorded file.

In a possible implementation manner of obtaining the recording information of at least one recording file and the corresponding configuration data (which may also be referred to as streaming data), a path of the recording file and a path of the configuration data may be obtained first, and then the recording information of the recording file and the corresponding configuration data may be obtained based on the respective paths.

The path of the recording file may be determined according to a specific storage location of the recording file, which is not specifically limited in this embodiment of the present application. For example, a Video folder 00000001 may be provided in an external device (e.g., a hard disk, etc.) connected to the display device, a recording file may be stored in the folder 00000001, and a path of the recording file may be a/tmp/lo _002/Video DR +/00000001 folder.

After obtaining the list path/tmp/lo _002/Video DR +/00000001 of the recording file, the MAC address 08ba5f9c17a6 of the display device may be concatenated to obtain the path of the configuration data as/tmp/lo _002/Video DR +/00000001/08ba5f9c17a6/00000001. cache. And then the recording information of at least one recording file and the corresponding configuration data can be obtained.

It can be understood that, in practical application, the recording information of at least one recording file and the corresponding configuration data thereof may also be obtained in other manners according to a specific application scenario, and the security of the configuration data can be ensured, which is not specifically limited in this embodiment of the present application.
