For better understanding of the technical solution in the embodiments of the present application, before describing the embodiments of the present application in detail, related content related to time shifting and recording will be described, where the time shifting and recording are two separate functions:
first, the related contents of the time shift function are introduced. In some embodiments, when the user watches a wonderful television program, such as a live broadcast program, particularly a live broadcast program, in spring, late spring, ball game, etc., the user is interrupted by an emergency, such as answering a call or going up a toilet, etc., the user can easily miss some wonderful moments, the time shifting function can provide the user with a choice for pausing the program and looking back at the missed content, the pause is started when the user leaves, the system starts to buffer the program data after the interface is paused, the play key is clicked when the user is busy with the emergency and returns to the display device, the program can be continuously played from the time when the user leaves, and in addition, the buffered program data is automatically deleted when the time shifting function exits.
Next, the related content of the recording function is introduced. In some embodiments, when a user watches a wonderful television program, the user feels more interested in recording the wonderful television program, and the user wants to watch the wonderful television program repeatedly, at this time, the user can start recording the current program, and stop recording the program manually after the program is played, so as to generate a recording file. When the program needs to be reviewed, the corresponding recorded file can be found for playing and review. In the recording process, according to the configuration of a specific model, a user can do other operations, for example, watching a network video or playing a local multimedia file, even watching programs of other channels, and the like, and in an example, a live program of the CCTV-1 can be watched while recording the program of the CCTV-5. In the embodiment of the application, the recorded file is permanently stored, and the user is prompted to selectively delete the content in the storage device when the storage device is insufficient, and in some embodiments, the storage device can be built-in storage, a USB flash disk or a mobile hard disk, etc.
In some embodiments, after the time shift is started, the user finds that the wonderful program is only watched once and is not addicted, and wants to record and repeatedly watch, and at this time, the current time shift function is stopped first, and then the recording function is started, so that inconvenience is brought to the operation of the user, and the stored program data cannot be stored in the time shift process before the recording function is started, and only the program content which is not yet played can be recorded. In some embodiments, because the memory space for caching data in the preset time shifting function is smaller, and the recorded memory space is larger, the time-shifting duration is shorter, and for a long-time live program, for example, the total time length of caching data in spring and late reaches 4 and a half hours, the total time length of caching data in the time shifting function cannot cover the whole program content, and after the time shifting function is started, a user often wants to review the content in front of spring and late, find that the content has expired, and the data is covered by new content.
In order to solve the technical problems, the embodiment of the application provides a method for switching a digital television program from time shifting to recording, which can be directly switched from a time shifting function to a recording function and can be realized only by one-step operation, thereby improving the use feeling of a user.
The method, as shown in fig. 5, includes: s100, when a digital television program is played, receiving an instruction for starting time shift, and caching the digital television program to obtain time shift data; and S200, controlling a display to play the time shift data.
In the embodiment of the application, the playing of the digital television program refers to playing the digital television program on the display device by using the traditional digital television service, and the program of the Shandong television is being played on the display device by way of example.
In some embodiments, the instruction to initiate the time shift may be generated by a user pressing a key on the control device, and, illustratively, may press a pause key on the control device. In other embodiments, the instruction for starting time shift may also call out a menu provided with a time shift control by pressing a button on the control device by the user, where the user interface displays a menu on an upper layer of displaying the digital television program, moves the focus to the time shift control, and presses a confirmation key on the control device to generate.
In the embodiment of the application, a time shifting starting instruction is received, a time shifting function is started, digital television programs starting from the moment of receiving the time shifting starting instruction are cached, time shifting data are generated, and a display is controlled to play the time shifting data.
In some embodiments, the playing the time shift data refers to displaying a first frame image of the time shift data. Illustratively, when playing the digital television program, the user presses a pause key on the control device, and the digital television program is no longer displayed on the display, but the first frame of image in the time-shift data is displayed. In other embodiments, the playing of the time shift data refers to playing the time shift data just before, that is, each frame of image in the time shift data is played in sequence.
In some embodiments, before buffering the digital television program for time shift data, the method further comprises: judging whether the display equipment meets the condition of caching the digital television program or not; if yes, caching the digital television program to obtain time shift data; if not, controlling the display to display a prompt message. In some embodiments, a memory is required for caching digital television programs, where the memory is used to store time shift data, and if a problem occurs, an exemplary no memory is available, then the condition for caching digital television programs is not satisfied, and the display is controlled to display a prompt message. If no problem exists, caching the digital television program to obtain time shift data.
In some embodiments, the interval of the second preset time determines whether the display device satisfies a condition for caching the digital television program. Because the memory is required to be applied for storing the digital television program, other operations may be required to prepare for the operation of caching the digital television program, when judging whether the condition of caching the digital television program is met, the second preset time is spaced, and related operations such as applying for content can be executed for the reserved time of the system.
In some embodiments, a time shift menu is displayed on top of the time shift data that controls the display to play, the time shift menu including a time shift transcription control. And when the user selects the time-shifting transcription control, the time-shifting business is directly transferred to the recording business. In some embodiments, the time-shift menu includes a time-shift transcription control, and further includes other controls.
Illustratively, as shown in fig. 6, a time shift menu 601 is displayed on top of the time shift data in fig. 6, the time shift menu 601 including a time shift record control 602, a fast reverse control 603, a play/pause control 604, a fast forward control 605, and an exit control 606. When the user moves the focus to the time-shift transcription control 602 by using the control device and presses the confirmation key on the control device, the input of selecting the time-shift transcription control is realized, and the time-shift function is switched to the recording function. In the embodiment of the present application, the recording function is not required to be started from other entries, and the recording function can be directly started from the time-shift transcription control 602 in the time-shift menu.
