In order to better understand the technical solution in the embodiment of the present application, before describing the embodiment of the present application in detail, the related contents of time shifting and recording are described, and the time shifting and recording are two separate functions:
first, the relevant contents of the time shift function are introduced. In some embodiments, when a user watches a wonderful television program, for example, some live broadcast programs, specifically, spring and late games, suddenly interrupted by emergency, such as answering a call or getting on a toilet, and the user easily misses some wonderful moments, the time-shift function can provide the user with a choice of suspending the program and reviewing missed content, the user starts to suspend when leaving, the system starts to buffer program data after the interface is suspended, and continues to play the program from the time the user leaves by clicking the play button after the user finishes the emergency and returns to the display device, and the buffered program data is automatically deleted when exiting the time-shift function.
Next, the content related to the recording function is introduced. In some embodiments, when a user is watching a highlight television program, the user feels more interested and wants to record the program for subsequent repeated watching, at this time, the recording can be started, the current program is recorded, and the recording is manually stopped after the program is played, so as to generate a recording file. When the program needs to be reviewed, the corresponding recording file can be found and played for review. In the recording process, according to the configuration of a specific model, a user can perform other operations, illustratively watch network videos or play local multimedia files, even watch programs of other channels and the like, and in one example, the user can watch live programs of CCTV-1 while recording programs of CCTV-5. In the embodiments of the present application, the recorded file is permanently saved, and when the storage device is insufficient, the user is prompted to selectively delete the content in the storage device.
In some embodiments, after the user starts the time shift, the user finds that the wonderful program is not addicted to be watched once, and wants to record and watch the wonderful program repeatedly, and at this time, the current time shift function needs to be stopped first, and then the recording function needs to be started, so that inconvenience is brought to 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 played can be recorded. In some embodiments, since the memory space for caching data in the preset time shifting function is small and the recorded memory space is large, the time-shiftable duration is short, for a long-time live program, for example, the spring and the evening are up to 4 half hours, the total duration for caching data in the time shifting function cannot cover the whole program content, and it often happens that after the time shifting function is started, a user wants to review the content before the spring and find that the content is expired and the data is covered by new content.
In order to solve the above technical problem, an embodiment of the present application provides a display method for switching a digital television program from time shifting to recording, where the method may directly transfer from a time shifting function to a recording function, and only one operation is required, so as to improve the user experience.
The method, as shown in fig. 5, includes: s100, when a digital television program is played, receiving a time shifting starting instruction, and caching the digital television program to obtain time shifting data; s200, controlling a display to play the time shifting data.
In the embodiment of the present application, the playing of the digital television program refers to playing the digital television program on the display device by using the conventional digital television service, and exemplarily, the program of the Shandong satellite television is being played on the display device.
In some embodiments, the instruction to initiate the time shift may be generated by a user pressing a key on the control device, for example, a pause key on the control device. In other embodiments, the instruction for starting time shift may also be generated by pressing a key on the control device by a user to call up a menu provided with a time shift control, where the menu is displayed on an upper layer of the digital television program displayed on the user interface, and moving the focus to the time shift control, and pressing a confirmation key on the control device.
In the embodiment of the application, a time shifting starting instruction is received, a time shifting function is started, a digital television program starting from the moment of receiving the time shifting starting instruction is cached, time shifting data is generated, and a display is controlled to play the time shifting data.
In some embodiments, the playing of the time shift data refers to displaying the first image of the time shift data. Illustratively, when the user presses the pause key on the control device while playing the digital television program, the digital television program is no longer displayed on the display, but the first frame image in the time shift data is displayed. In other embodiments, the playing time shift data refers to normal playing time shift data, that is, each frame of image in the time shift data is played in sequence.
In some embodiments, before caching the digital television program and obtaining the time shift data, the method further comprises: judging whether the display equipment meets the condition of caching the digital television program; if yes, caching the digital television program to obtain time shifting data; and if not, controlling the display to display a prompt message. In some embodiments, it is desirable to apply for a memory for caching the digital television program, where the memory is used to store the time-shift data, and if a problem occurs and an exemplary memory is not available, the condition for caching the digital television program is not satisfied, and the display is controlled to display a prompt message. If no problem exists, the digital television program is cached to obtain the time shifting data.
In some embodiments, whether the display device meets the condition of caching the digital television program is judged at a second preset time interval. Because the application memory is required for storing the digital television program to realize the storage of the digital television program, and 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 application content and other related operations can be executed for the system reserved time at intervals of the second preset time.
In some embodiments, a time-shift menu is displayed on the upper layer of the time-shift data that controls the display to play, the time-shift menu including a time-shift recording control. And when the user selects the time shifting recording control, directly switching from the time shifting service to the recording service. In some embodiments, the time-shift menu includes other controls in addition to the time-shift recording control.
Illustratively, as shown in fig. 6, a time shift menu 601 is displayed on the upper layer of the time shift data display in fig. 6, and the time shift menu 601 includes a time shift recording control 602, a fast rewind 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 recording control 602 by using the control device and presses the enter key on the control device, the user selects the input of the time shift recording control and shifts from executing the time shift function to executing the recording function. In the embodiment of the present application, it is no longer necessary to start the recording function from another entry, and the recording function may be directly started from the time-shift transfer control component 602 in the time-shift menu.
