Detailed Description
In the embodiment of the invention, a virtual disk system is installed on the television, the television performs registration management on at least one storage device inserted by a user through the virtual disk system, and the television sets a virtual storage space in the virtual disk system and respectively maps each storage device in the virtual storage space to a corresponding storage subspace, so that the television can determine whether at least one storage device exists locally by detecting whether at least one storage subspace exists locally, and further can store recorded contents through at least one storage device existing locally.
In practical applications, the storage device may be a different type of device, such as a usb disk, a removable hard disk, and so on.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, in the embodiment of the present invention, in the preprocessing process, a specific process of registering, by a television, at least one storage device through a virtual disk system is as follows:
step 101: the television detects that the user has inserted at least one storage device.
Step 102: and the television performs registration management on the at least one storage device.
Specifically, after the television determines that the user inserts at least one storage device, the identification information of each storage device in the at least one storage device is acquired through the virtual disk system, and registration management of the at least one storage device is completed.
Step 103: the television maps each storage device locally to a corresponding storage subspace.
Specifically, the television sets a virtual storage space in the virtual disk system, then maps each storage device in the virtual storage space to a corresponding storage subspace, and establishes a corresponding relationship between the identification information of each hard disk and the corresponding storage subspace.
For example: referring to table 1, after successful registration, the correspondence between the identification information of the storage device stored on the television and the storage subspace is as follows:
the identification information of the storage device 1 is device 1, the corresponding storage subspace is subspace 1, the identification information of the storage device 2 is device 2, the corresponding storage subspace is subspace 2, the identification information of the storage device 3 is device 3, and the corresponding storage subspace is subspace 3.
TABLE 1
| Hard disk device name | Identification information | Corresponding storage sub-spaces |
| Hard disk device 1 | Device 1 | Subspace 1 |
| Hard disk device 2 | Device 2 | Subspace 2 |
| Hard disk device 3 | Device 3 | Subspace 3 |
Based on the above embodiment, after the storage device is successfully registered, the television can start to use the storage device to store the recorded multimedia program. Referring to fig. 2, in the embodiment of the present invention, a specific process for recording a multimedia program by a television is as follows:
step 200: and the television records the multimedia program to obtain recorded content.
Step 201: and the television stores the obtained recorded content into a recording file cache.
Specifically, the virtual disk system is installed on the television, the recording file cache is arranged in the virtual disk system, and after the television obtains the recorded content, the recorded content is stored through the recording file cache in the virtual disk system.
Step 202: the television determines whether at least one registered storage device exists locally, if so, step 204 is executed, otherwise, step 203 is executed.
Specifically, after the television completes registration management on at least one storage device through the virtual disk system, each storage device locally has a corresponding storage subspace in the virtual storage space, so that the television can locally detect and judge whether at least one storage subspace locally exists, if so, it is indicated that at least one registered storage device locally exists, otherwise, it is indicated that at least one registered storage device locally does not exist, and it is determined that a prompt needs to be sent to the user.
Step 203: the television prompts the user to insert at least one storage device and registers the at least one storage device after determining that the user inserted the at least one storage device, and then returns to step 202.
Specifically, after determining that at least one registered storage device does not exist locally, the television prompts the user, optionally, the television pops up a window on a screen, and displays a content "please insert a storage device" in the window, and the user learns that at least one registered storage device does not exist locally in the television and needs to insert at least one storage device through the display content in the window.
Step 204: the television selects one of the at least one locally registered storage device as a first target storage device, stores the recorded content in the recording file cache in the first target storage device, and then executes step 205.
Specifically, the television is preset with a screening condition, and after the television starts recording the multimedia program, the storage device meeting the screening condition is selected from the plurality of locally registered storage devices as a target storage device.
Specifically, when setting the filtering condition, the television may adopt, but is not limited to, the following modes:
the first method is as follows: the user selects "the remaining storage space is maximum" as the filtering condition.
Suppose there are three registered storage devices locally, respectively: storage device 1, storage device 2 and storage device 3. Then, after determining that the user selects "remaining storage space is maximum" as the filtering condition, the television detects the remaining storage space of the local three registered storage devices. After the television is detected, the remaining storage space of the storage device 1 is determined to be 8G, the remaining storage space of the storage device 2 is determined to be 7G, and the remaining storage space of the storage device 3 is determined to be 11G, so that the remaining storage space of the storage device 3 is determined to be the maximum, the storage device 3 is used as a first target storage device, and the recorded content in the recorded file cache is stored in the storage device 3.
The second method comprises the following steps: the user selects "fastest transmission speed" as the screening condition as an example.
Suppose there are three registered storage devices locally, respectively: storage device 1, storage device 2 and storage device 3. Then, after determining that the user selects "fastest transmission speed" as the filtering condition, the television detects the transmission performance of the local three registered storage devices. After the television is detected, the transmission speed of the storage device 1 is determined to be 10Mb/s, the transmission speed of the storage device 2 is determined to be 30Mb/s, and the transmission speed of the storage device 3 is determined to be 15Mb/s, so that the transmission speed of the storage device 2 can be determined to be the fastest, and therefore the storage device 2 is used as a first target storage device, and the content in the recording file cache is stored in the storage device 2.
Step 205: the television detects that the user carries out hot plug on the first target storage device in the recording process.
Step 206: and the television detects locally again, judges whether at least one registered storage device still exists locally, if so, executes step 207, otherwise, returns to step 203.
Specifically, after detecting that a user hot plugs a first target storage device in a recording process, the television stores the recorded content obtained after the hot plugging into a recording file cache, because the television performs registration management on at least one storage device through a virtual disk system, each storage device locally has a corresponding storage subspace in a virtual storage space, the television can locally re-detect and judge whether at least one storage subspace still exists, if so, the fact that at least one registered storage device still exists locally is indicated, otherwise, the fact that at least one storage device does not exist locally is indicated, and it is determined that the user needs to be prompted.
Step 207: after the television determines that at least one registered storage device still exists locally, the television performs screening again in the at least one registered storage device according to the screening conditions, uses one storage device meeting the screening conditions as a second target storage device, and stores the recording content in the recording file cache into the second target storage device.
Specifically, when the television determines the first target storage device, the filtering condition is already determined according to the user instruction, so that after the television determines that at least one registered storage device still exists locally, the filtering condition selected by the user before is carried out again in the at least one storage device, and one storage device meeting the filtering condition is used as the second target storage device.
In addition, in practical application, the television may preset a data volume threshold or/and a time length threshold according to a user instruction, and when the television fails to determine the second target storage device for a long time, if it is determined that the operation of storing the recording content obtained after hot plug into the recording file cache reaches the data volume threshold or/and the time length threshold, the recording of the multimedia program is stopped.
Taking the preset data volume threshold as 2G as an example, when the television has determined that the data volume of the recorded content stored in the recording file cache reaches the preset data volume threshold 2G, if the second target storage device is not determined yet, the recording of the multimedia program is stopped.
Taking the preset time length threshold of 300s as an example, when the duration of the process that the television already determines to store the recording content in the recording file cache reaches the preset time length threshold of 300s, if the second target storage device is not determined yet, the recording of the multimedia program is stopped.
Step 208: the television judges whether the recorded content is successfully stored in the at least one registered storage device, if so, step 209 is executed, otherwise, step 202 is returned.
Step 209: the television judges whether the recording of the multimedia program is finished, if so, the step 210 is executed, otherwise, the step 200 is returned to.
Specifically, in the recording process, the television monitors the recording process of the multimedia program in real time and judges whether the recording of the multimedia program is completed.
Step 210: the television prompts the user that the recording of the multimedia program has been completed.
Specifically, the television pops up a window on the screen, the display content of the window is "recording end", and the user can know that the recording of the multimedia program is ended through the display content in the window, and at this time, the user can perform hot plug on at least one local registered storage device.
