The PVR can use the built-in hard disk as a storage medium, establish a local mass buffer area and a huge program storage library, and can edit and record and play programs. The recording and playing control comprises hard disk program recording and hard disk program playback. The recording of the hard disk program refers to storing a TS (Transport Stream) Stream of the target program and related information on the hard disk in a certain data organization format. Program playback means that program information (including content, length, code rate, addition time, etc. of programs) of all programs stored on a hard disk is listed in the form of an OSD (on-screen display) menu through the display device 200, a user can select a program desired to be watched through a remote controller, and the display device 200 plays the program selected by the user.

Fig. 7 illustrates a schematic diagram of built-in hard disk program recording in some embodiments. As shown in fig. 7, the TS stream obtained by front-end demodulation enters the programmable transport interface module via the multiplexer. The programmable transport interface module is a special microprocessor integrated in the main control chip, i.e. the control device in the display device 200, and has the main task of completing analysis, descrambling and de-multiplexing of the TS stream. The self-contained on-chip cache can carry out data transmission with external storage in a DMA (Direct Memory Access ) mode, and the hardware support is provided for the hard disk recording and playing function of programs. The programmable transmission interface module extracts corresponding TS packets of programs to be recorded in the TS stream, stores the TS packets into an on-chip cache, when the TS packets are received, informs a software part through a driver, and is responsible for copying the TS packets in the on-chip cache into an external storage, and once an area (the size is 64KB for example) opened up for reading and writing of a hard disk in the external storage area is full, data is written into the hard disk from the external storage area, so that the whole recording process is completed. Meanwhile, due to the multi-channel gating function of the multiplexer and the multi-program gating function of the programmable transmission interface unit, the program can be played back in real time while being recorded, and other programs can be watched while the program is recorded. Display device 200 may store the recorded asset program in the form of a file to a built-in storage device.

In some embodiments, a user may view all files stored in display device 200. FIG. 8 illustrates a schematic diagram of a display device 200 displaying a file browsing interface in some embodiments. As shown in fig. 8, all files stored in a storage device built into the display device 200 may be included in the file browsing interface. Files may be divided by resource type, such as video, pictures, music, and novels.

When a user browses a file, the user needs to control a file browsing interface through a direction key and a determination key on the remote controller so as to select the file to be checked. It should be noted that, with the use of the display device 200 by the user, the number of files that may be stored in the storage device may be larger, and these files may be arranged in multiple tiers, that is, multiple files of the same tier may be stored in one folder, and multiple folders of the same tier may also be stored in folders of a previous tier. When browsing files, a user needs to enter from the root directory of the storage device, and browse the files step by step according to the hierarchical sequence of the folders. If a user is interested in a certain file, for example, a certain video file has a high preference, the file may be viewed multiple times to view the corresponding video. If the file is deeper in hierarchy, the user needs to enter from the root directory each time and search step by step, so that the operation is complicated, the time consumption is long, the file access efficiency is seriously reduced, and the use experience for the user is poor.

In order to solve the above-mentioned problem, the display device 200 provided in the embodiment of the present application may have a file shortcut access setting function, and may set a shortcut access to a file. The display device 200 may be provided with a file shortcut access setting mode. When a user browses a file, if the user is interested in a certain file, the file can be set to be accessed quickly, and the display device 200 can generate a corresponding control capable of being accessed quickly according to the file. When the user wants to search, the user can directly access the file without searching in sequence from the catalogues of a plurality of layers, the operation is simple and convenient, the file access efficiency is improved, and the use experience of the user is improved.

In some embodiments, the user may send a file shortcut access setting mode instruction to the display device 200 by operating a designated key of the remote controller. And (3) pre-binding the corresponding relation between the file shortcut access setting mode instruction and the remote controller key in the actual application process. For example, a file shortcut access setting mode key is set on the remote controller, and when the user touches the key, the remote controller sends a file shortcut access setting mode instruction to the controller 250, and at this time, the controller 250 controls the display device 200 to enter the file shortcut access setting mode.

A file shortcut access setting mode option may also be set in the system UI interface of the display device 200, and when the user clicks the option, the display device 200 may be controlled to enter or exit the file shortcut access setting mode.

In some embodiments, to prevent the user from false triggering the file shortcut access setting mode, when the controller 250 receives the file shortcut access setting mode instruction, the display 260 may be controlled to display file shortcut access setting mode confirmation information, so that the user performs a secondary confirmation as to whether to control the display device 200 to enter the file shortcut access setting mode. Fig. 9 is a diagram illustrating file shortcut access settings mode confirmation information in some embodiments.

The controller 250 may control the display 260 to display a file browsing interface corresponding to the first storage device, the file browsing interface including at least one file stored in the first storage device. Each storage device may correspond to a file browsing interface for displaying the file conditions stored in the responsive storage device.

The user may select a file to be viewed in the file browsing interface. In this embodiment, a file selected by a user is referred to as a first file. After the user selects the first file, the user may be considered to input an instruction for displaying the first file, and the controller 250 may control the display 260 to display the file content of the first file for viewing by the user.

In some embodiments, the user may set the file to be accessed quickly, thereby enabling convenient viewing of the file. The shortcut access can be used as an editing function of the file, and can be selected to be set when a user edits the file. Taking the first file as an example, the user may input an edit instruction for the first file to edit the file.

In order to distinguish between instructions to present a file and instructions to edit a file, it may be set to: when the user clicks the control corresponding to the file, the controller 250 may generate an instruction to display the file; when the user presses the control corresponding to the file for a long time, the controller 250 may generate an instruction to edit the file.

After the user instructs to edit the first file, the controller 250 may control the display 260 to display a file editing interface in response to the editing instruction. The file editing interface is used for performing quick access editing operation on the first file, and may further include some other file editing functions, such as copy operation, cut operation, rename operation, and the like.

In some embodiments, considering that the user may have set the shortcut access operation to the first file, the shortcut access operation is not required to be provided any more, and a function of canceling the shortcut access operation may be provided. For this reason, the display apparatus 200 may display different file editing interfaces for different cases of whether the first file is set with quick access.

In response to an edit instruction to the first file, the controller 250 may first detect a quick access status of the first file, the quick access status characterizing whether the file has been added with quick access.

If the shortcut access status indicates that the first file is not added with the shortcut access, the controller 250 may control the display 260 to display the first file editing interface. FIG. 13 illustrates a schematic diagram of a first file editing interface in some embodiments. As shown in fig. 13, the first file editing interface includes an add control, a copy control, a cut control, and a rename control. The adding control is used for adding shortcut access to the file.

In response to a selected operation of the add control, the controller 250 may generate an instruction indicating to add the first file to the quick access. At this time, the first file may be set to be accessed quickly.

If the shortcut access status indicates that the first file has been added with the shortcut access, the controller 250 may control the display 260 to display the second file editing interface. FIG. 14 illustrates a schematic diagram of a second file editing interface in some embodiments. As shown in fig. 14, the second file editing interface includes a remove control, a copy control, a cut control, and a rename control. The removal control is used for removing shortcut access to the file.

In some embodiments, files of different shortcut access states may also use the same file editing interface.

In response to an edit instruction to the first file, the controller 250 may detect a shortcut access status of the first file. When the file is in different shortcut access states, the display states of the shortcut access related controls may be different.

The controller 250 may control the display 260 to display the third file editing interface. The third file editing interface comprises an adding control and a removing control which are respectively used for adding shortcut access and removing shortcut access to the file.

When the shortcut access state characterizes that the first file is not added with shortcut access, adding a control as a selectable state, and removing the control as an unselected state; and when the shortcut access state characterizes that the first file has been added with shortcut access, adding the control to be in an unselected state, and removing the control to be in an unselected state.

FIG. 15 illustrates a schematic diagram of a third file editing interface in some embodiments. As shown in fig. 15, if the first file is currently in the shortcut access not added, the adding control is in a selectable state, and the removing control is in an unselected state. I.e. the operation of setting up the shortcut access to the first file can currently be performed, but the operation of canceling the setting up the shortcut access cannot be performed. Wherein the control is rendered gray and is rendered unselected.

In some embodiments, when the user selects the add control, controller 250 generates an instruction indicating that the first file is added to the quick access. In response to the instruction, the controller 250 may obtain the device identification of the first storage device and the storage address of the first file. The first storage device is a storage device for storing a first file. The controller 250 may determine the storage device to which the first file belongs and the storage address for subsequent quick access.

It should be noted that the file itself is data, and the data under multiple directories cannot be directly accessed. For this purpose, the file may be regarded as a virtual device so that the display device 200 can directly start the virtual device.

After the user instructs to set the shortcut access to the first file, the controller 250 may first store the device identifier of the first storage device and the storage address of the first file in a preset database.

Based on the device identification and the storage address, the controller 250 may generate a virtual device control corresponding to the first file. The virtual device control has a matching relationship with the device identifier of the first storage device and the storage address of the first file. Based on the virtual device control, the first file may be accessed.

To present the user with a quick accessible file, the controller 250 may update the storage device list based on the virtual device controls, which may be added to the storage device list. I.e., the updated storage device list includes the virtual device control and the device control corresponding to the storage device supported by the display device 200. The first file may be used as a virtual storage device, and the controller 250 may directly access the first file when the user instructs the start-up.

In some embodiments, after the user indicates that the first file is set to be accessed quickly, the controller 250 may generate a virtual device control and add it to the storage device list to update the storage device list.

When the user inputs an instruction to query the storage device again, the controller 250 may control the display 260 to display the updated storage device list. The storage device list includes at least one virtual device control, which may be one or more. The user may select one of the virtual device controls to make quick access to the corresponding file.

In response to a selection operation of the target virtual device control, the controller 250 may obtain a target device identifier and a target storage address corresponding to the target virtual device control.

Based on the target device identification, the controller 250 may determine a target storage device to which the target file corresponding to the target virtual device control belongs. Based on the target storage address, the controller 250 may access the target file in the target storage device and control the display 260 to display the target file to enable the user to view the file content.

In some embodiments, the user may also cancel setting the shortcut access to the first file if the shortcut access to the first file is already set while the display device 200 displays the file editing interface. The user may select the remove control.

In response to a selected operation of the remove control, the controller 250 may generate an instruction indicating that the first file is removed from the quick access. It should be noted that, when the first file sets the shortcut access, a virtual device control corresponding to the first file exists in the storage device list. To this end, the controller 250 may delete the virtual device control corresponding to the first file from the storage device list to cancel setting the shortcut access of the first file.

In some embodiments, controller 250 may also update the storage device list synchronously as the presence status of the file changes. For example, for a file in an external storage device, if shortcut access is set but the storage device is disconnected from the display device 200, the display device 200 cannot access the file, and thus the shortcut access of the file cannot be realized. Thus, the storage device list may be updated to ensure that devices in the storage device list (including both real devices and virtual devices) may be booted up normally.

The controller 250 may acquire the device connection state of the external apparatus interface in real time to detect whether there is a storage device connected to the display device 200 or to pull out the display device 200.

Based on detecting that the second storage device is disconnected from the display apparatus 200, it may be that the second storage device is unplugged from the external device interface, or it may be that the second storage device itself fails to be communicatively connected to the display apparatus 200, and the controller 250 may obtain the device identifier of the second storage device. The controller 250 may detect a device identification of a storage device corresponding to each control in the current storage device list, including a real storage device and a virtual device.

If the device identifier of the first virtual device control and the device identifier of the second storage device are the same, the controller 250 may delete the device controls corresponding to the first virtual device control and the second storage device from the storage device list to update the storage device list.

In some embodiments, when an external storage device is connected to the display device 200, the device may have been previously connected to the display device 200, and the user has set up quick access to a certain file in the device. To enhance the user's use experience, the display device 200 may reset the shortcut access to the file for which the shortcut access was previously set, in compliance with the user's preference.

The controller 250 may acquire the device connection state of the external apparatus interface in real time.

Based on detecting that the second storage device and the display device 200 are connected, the controller 250 may acquire a file shortcut access status in the second storage device. The file shortcut access status is used to characterize whether a file in the storage device has been added shortcut access in the display device 200.

If there is a shortcut access to the second file, the controller 250 may generate a second virtual device control corresponding to the second file, and add the second virtual device control and a device control corresponding to the second storage device to the storage device list to update the storage device list.

If there is no file in the second storage device that adds too fast access in the display device 200, the controller 250 may simply add the device control corresponding to the second storage device to the list of storage devices.

In some embodiments, a delete control may be included in the file editing interface for deleting a file from the storage device. If the user indicates that the deleted file is provided with quick access, the file cannot be accessed continuously after the file is deleted, and the storage device list needs to be updated synchronously.

In response to a user's selection of the delete control, the controller 250 may detect a shortcut access status of the first file and delete the first file. The shortcut access status is used to characterize whether a file has shortcut access added.

If the shortcut access status characterizes that the first file has been added with the shortcut access, the controller 250 may delete the virtual device control corresponding to the first file from the storage device list to update the storage device list.
