Based on the above-described display apparatus 200, in order to enrich the viewing functions of the user, improve the viewing experience of the user, the display apparatus 200 is configured to be able to provide the playback functions of the program data for the user. The playback function of the display device may enhance the user's experience and may be selected by the user when he or she is missing certain programs or wants to watch certain programs again. Typically, a user needs to first send a recording instruction to start recording program data of a target program to be played back, and the user looks back by playing the recorded program data. A user typically has a program in a channel as the basic unit of review, a program being a television program having complete program content, such as a episode of a television show or a match, etc.

Fig. 5 is a schematic diagram of a recording mode of the display device according to the embodiment of the present application, where a progress bar indicates a time corresponding to program data, and a gray portion on the progress bar indicates program data that is finally recorded, that is, program data that can be played back. Taking the example of the display device 200 being turned on as a display node of program data (in this example, the display device 200 does not switch channels), the display device 200 is turned on at t=0, starts playing the program A1, and receives a recording instruction sent by the user at t=t1, the recording instruction indicating that the program data is recorded from t=t1, and the display device 200 starts recording the program data of the current program from t=t1 and ends recording at t=t2 in response to the recording instruction.

After recording is completed, the user may initiate a playback mode or playback function to play back the recorded video file. In the process of playing back the recorded video file, a user can play the recorded video file in sequence, and can drag a progress bar or operate a fast forward/fast backward key to jump to a designated position for playing, so as to watch the program content corresponding to the position. However, for some specific scenes or contents in the recorded video file, the user can only perform fast forward/fast backward operation frequently, so that the program content which wants to review can be roughly selected, and the problem of poor control experience is solved.

In order to improve the interactive experience of the user, some embodiments of the present application provide a method for positioning and playing a streaming media, which stores the event information of a recorded program in a recorded video file during recording based on the event information in an EPG service, and corresponds the event information to the recording position one by one, so as to well solve the problems that when the recorded video file is watched by using the playback function provided by the display device 200, the user can only roughly select the program corresponding to the time point that the user wants to review by fast forwarding and fast rewinding frequently, which is complex in operation and affects the user experience.

As shown in fig. 6 and fig. 7, the method for positioning and playing streaming media includes a recording process and a playback process. The display device 200 may be configured to perform the program steps of the streaming media positioning playing method, and the steps performed by the display device 200 in the following embodiments are all completed by the controller 250 in cooperation with other components in the display device 200.

S610: and acquiring a recording instruction input by a user.

The display device 200 may acquire a recording instruction issued by the user. The recording instruction may be directly sent to the display device 200 by the user, or the user may send the display device 200 through other devices.

In some embodiments, the user may send a recording instruction to the display device 200 through the control apparatus 100, where the control apparatus 100 may be a remote controller, a mobile phone, a tablet computer, or the like.

In some embodiments, the user may also send recording instructions directly to the display device 200. Such as directly sending voice commands, touch commands, gesture commands, etc., to the display device 200. The display device 200 collects actions or operations of a user through an image collection device, a sound collection device, a touch control device, etc., or collects information or instructions sent by the user, and recognizes recording instructions sent by the user therefrom.

For example, the user transmits a recording instruction to the display device 200 by manipulating the control apparatus 100, and the user manipulates the focus to move to the "record" key on the user interface by pressing the "up", "down", "left", "right" key of the remote controller, and transmits the recording instruction to the display device 200 by pressing the "ok" key of the remote controller, or transmits the recording instruction to the display device 200 by directly pressing the "record" key of the remote controller.

S620: and responding to the input recording instruction, and acquiring program information of the program to be recorded from the recording instruction.

The display device 200 may activate a recording mode or recording function in response to the recording instruction, and display a recording parameter menu including a recording parameter that may be set and an edit area corresponding to each recording parameter, and in some embodiments, the recording parameter includes a recording start time, a recording end time, a recording mode, and a corresponding edit area (text box).

In some embodiments, controller 250 receives a recording parameter setting instruction sent by the user; controlling the display to display a user interface with a recording parameter menu in response to the recording parameter setting instruction, wherein the recording parameter menu comprises at least one recording parameter and an editing area corresponding to the at least one recording parameter; receiving an editing instruction sent by the user, wherein the editing instruction is used for indicating the editing area to be edited and editing content; and responding to the editing instruction, and filling the editing content in the editing area.

For example, the user sends a recording parameter setting instruction to the display device 200 by manipulating the control device 100 to instruct the display device 200 to input the corresponding editing content in the text box, so as to complete the setting of the recording parameter. In some embodiments, in order to facilitate the setting of the user, for example, in a case that the user cannot accurately know the playing start time and the playing end time of the target program, and cannot accurately determine the recording start time and the recording end time, the display device 200 may analyze the program name provided by the program data in the recording parameter menu, and the playing start time and the playing end time corresponding to the program, so that the user may indirectly select the recording start time and the recording end time by directly selecting the program name of the target program; the recording start time is smaller than or equal to the playing start time of the target program, and the recording end time is larger than or equal to the playing end time of the target program.

In the embodiment of the present application, before recording the video file, the controller 250 obtains EIT (event information table) in the EPG table, where the event information table includes data related to the event or the event content description, such as the name, start time, time length, running state, event detailed description, etc. Specifically, a recording instruction sent by a user is received, a recording request is obtained from the recording instruction, an electronic program guide related to the recording request is obtained, and event basic information of each event of a program to be recorded in the recording request is obtained according to the electronic program guide. The to-be-recorded programs in the application include, but are not limited to, television programs, live programs and short video programs, and the streaming media positioning playing method provided by the application is described below by taking the to-be-recorded programs as television programs.

Assuming that a user sets to record television programs in the XX date 13:00-16:00 channel N, before starting to record the television programs, acquiring event basic information in a corresponding recorded video file set by the television program user played by the XX date channel N in the 13:00-16:00 according to an electronic program guide related to a recording request, and recording each event and the starting time of each event. For example, the electronic program guide is used to obtain the video file to be recorded, which is set by the user and includes the event 1 movie program, the event 2 news program and the event 3 food program, and obtain the starting time of each event, for example, the starting time of the event 1 is 13:00, the starting time of the event 2 is 14:30, and the starting time of the event 3 is 15:00.

S630: and when the currently played event belongs to the program to be recorded, acquiring the playing progress of the currently played event.

The display device 200 obtains the currently played event by analyzing the currently received program data, so as to determine the playing end time of the corresponding current program according to the currently played event, and determine that the program to be recorded is the program to be recorded, namely the target program, by comparing the recording start time with the playing end time of the current program. When the recording start time is smaller than the playing end time of the current program, the target program is the current program; when the recording start time is greater than or equal to the playing end time of the current program content, the target program refers to the program to be played after the current program.

For example, the current program is a program A1, the playing end time of the program A1 is T3, and if the recording start time set by the user is T2 and T2 < T3, it may be determined that the target program to be recorded by the user is the program A1. If the recording start time set by the user is T4, and T4 is equal to or greater than T3, it can be determined that the target program to be recorded by the user is a program to be played after the program A1, for example, the program A2.
