In some embodiments, as shown in fig. 7, the channel name and program name are presented in the form of tickers, wherein the channel name and program name can display special characters and are not limited by the number of words.

In the related art, when recording starts, a recording file name is generated according to recorded content, and then the recorded content is generated according to the file name. The format of the recording file name is as follows: channel name _ program name _ month _ day _ year _ hour _ minute _ extension. The method stores the related information in the file name, and can acquire the recording information as long as the recorded file is acquired when the format is fixed. However, the file name has a limitation in length, and when one or more pieces of information are long, the limitation that the conventional file name has a maximum of 255 characters may be broken. For example, certification authorities in certain countries have test content with channel or program names exceeding 255 bytes. And the special character can not be used as a file name, when the special character appears, the character after the escape can not be correctly inverted, and the displayed information is distorted. Although special characters such as "Twill", "Twill. For example, the language words vary from country to country in the world, and other language words that are not easily recognized may appear in the channel name or program name.

For example, the user wants to record the channel name test aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa; the program name is test bbb & bbb! bbbbbbbbbb! bbbbbbbbbbbb. If the channel name and the program name are both stored in the recorded file name, the channel name and the program name cannot be completely displayed once the channel name and the program name exceed 255 bytes, and abnormal characters or special characters cannot be transferred to the original characters. The recording channel name may be shown as test _ aaa _ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.

In order to solve the foregoing technical problem, an embodiment of the present application provides a method for recording a file, where a flowchart of the method is shown in fig. 8, and the method specifically includes:

According to the method and the device, the user can select the storage position of the recorded file and use the storage position as the display information, so that the user can know the storage position of the recorded file, and the recorded content on each storage device can be more easily identified during storage.

Step S85: adding the display information to the recording list database;

step S86: generating a recording file name according to the display information;

step S87: generating a recording file of a recording file name;

in some embodiments, generating the recording file that records the file name includes a process from the start of recording to the completion of recording of the file.

Step S88: and updating the recording list database.

In some embodiments, at the end of recording, the presentation information, some of which need to be updated, needs to be updated again, for example, the recording end time and the size of the space occupied by the recording file.

If it is detected that the recording list database does not exist, step S89 is performed.
