Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Various non-limiting embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example one
The video playing method provided in this embodiment is applied to a terminal, where a processor is disposed in the terminal, and the processor executes the steps of the video playing method provided in this embodiment, so that the terminal plays a video according to the video playing method provided in this embodiment, and the terminal may be, but is not limited to, a computer, a mobile phone, a tablet computer, a vehicle-mounted device, a wearable device, and the like.
Referring to fig. 1, fig. 1 is a flowchart illustrating a video playing method according to an embodiment of the present invention. The video playing method comprises the following steps:
s100, acquiring the starting time and the ending time of a target segment in a target video, and downloading target video data according to the starting time and the ending time.
The target video data comprises first video data and second video data, the first video data is the video data of the target segment, and the second video data comprises video data of a first preset duration before the starting time and video data of a second preset duration after the ending time. Specifically, when a user browses a video website or uses a video application by using a terminal, the video website and the video application can display a plurality of videos, the user can select the target video to watch according to the needs of the user, the user can select the target video by means of click operation or voice control, and after selecting the target video, the user can select whether to watch a target segment in the target video, specifically, the user can select whether to start functions of 'only watching him' or 'only watching a climax part', and the like, and select to watch one or more segments preset in the target video, wherein the target segment is one or more segments preset in the target video.
Specifically, many video websites and video applications have developed functions of "only see him" and "only see climax part", one or several segments are set in advance from a longer video, the user does not play the whole video when starting the functions of "only see him" or "only see climax part", but automatically skips other parts, sequentially plays one or several preset segments in the video, for example, the "see only" function, is to select and mark in advance segments of the video where a certain actor appears, when the user selects to only see a certain actor, the segments of the actor appearing in the video selected in advance are automatically played in sequence, the function of only watching the climax part is to mark the wonderful segments in the video in advance, and when the user selects to start the function of only watching the climax part, the wonderful segments selected from the video in advance can be automatically played in sequence. However, since the contents of the video mostly have front-back continuity, in many cases, the scenario of an actor may exceed the range of the segment where the actor appears, a highlight segment may be generated due to long-time accumulation, which may cause the scenario to be discontinuous when only the segment of the actor or the highlight segment is watched, the scenario cannot be understood, and the user may have interest in the start and the end of the scenario of the segment after watching a segment, which may cause the user to know the start of the scenario of the segment by pulling the progress bar to watch a small part of the content before the segment before watching the segment when watching a segment, or to watch the content after the segment to know the end of the scenario after watching the segment by pulling the progress bar after watching the segment, and, a user who has turned on the "see only" function tends to be discouraged from a scenario that is not associated with the relevant actor, and therefore, after selecting a target segment, the user will mostly view only the preceding and following segments of the target segment to determine whether the relevant scenario exists. And under the 'only watching the other' mode, the terminal only downloads the data of the preset segment, and when a user watches a certain preset segment, the user plays and downloads the data of the rest segments simultaneously, so that the user is ensured to play more smoothly when watching the next segment, but when watching the content of the non-preset segment, the user cannot download in advance, and the phenomenon of unsmooth playing or even blockage can be caused.
In order to solve the above problem, in the video playing method provided in this embodiment, after the user selects to play the target segment in the target video, in addition to downloading the video data of the target segment, the video data in a period of time before and after the target segment is downloaded, so that when the user finishes watching the scenario of the target segment from the target segment or generates interest later to watch the video content adjacent to the target segment, a smooth watching experience can be obtained.
Specifically, the first preset duration and the second preset duration may be equal or different, specific values of the first preset duration and the second preset duration may be set according to the content type, the total duration, and the like of the target video, for example, when the target video is a variety, a continuous scenario may not generally generate a relatively large time span, the first preset duration and the second preset duration may be set to be shorter, for example, 1 minute, 30 seconds, and the like, when the target video is a tv series, a movie, and the like, a scenario with a relatively large span may be generated, and the first preset duration and the second preset duration may be set to be longer, for example, 5 minutes, 10 minutes, and the like.
Before the start time and the end time of the target segment in the target video are obtained, the video playing method provided by this embodiment further includes the steps of:
and acquiring a segment selection instruction, and determining the target segment according to the segment selection instruction.
Specifically, the target video may be provided with a plurality of segments according to different setting rules, and a user may select the target segment desired to be viewed according to his own needs, for example, a tv series, a video website or a video application may be divided into 3 segment combinations according to the exhibition time of 3 main actors in advance: the target segments are determined to be segments corresponding to the actors if the user selects the 'only see' function of one of the actors, for example, if the user selects only see the actor a, the pre-selected segments in which the actor a appears are taken as the target segments.
Referring to fig. 1 again, the video playing method provided in this embodiment further includes the steps of:
s200, decoding the first video data and then playing.
The first video data is the video data of the target segment and the video data of the segment which is selected by the user and wanted to be watched, so that the first video data can be directly decoded and played after being downloaded. Specifically, the decoding and playing of the first video data is to decode and output the first video data to a screen for playing, where the screen may be a screen of a terminal itself or a display screen in communication connection with the terminal.
After downloading the target video data according to the start time and the end time, since the user does not necessarily generate interest in video content before and after the target segment after finishing watching the target segment, after the second video data is obtained by downloading, the second video data may not be decoded temporarily, and specifically, the second video data may be processed and then sent to the decoding module, so that the decoding module does not decode the second video data. And the target segment is a segment which the user has selected to watch, so the first video data can be directly sent to a decoding module, and the decoding module decodes and plays the first video data.
Namely, after downloading the target video data according to the start time and the end time, the method further comprises the following steps:
directly sending the first video data to a decoding module;
and processing the second video data and then sending the second video data to the decoding module.
Specifically, the directly sending the first video data to a decoding module includes:
and generating a data transmission driving signal to control a video transmission control module to generate a transmission signal, wherein the frequency of the transmission signal is greater than the output speed of the first video data.
The output speed of the first video data is the speed of the processor of the terminal for outputting the first video data, after the processor of the terminal downloads the first video data, the processor generates a data transmission driving signal to control a video transmission control module to generate a transmission signal with the frequency f, the transmission signal is used for transmitting the first video data to the decoding module, the frequency f of the transmission signal is greater than the speed of the processor for outputting the first video data, namely, the video transmission control module communicates with the processor of the terminal according to the transmission signal with the frequency f, transmits the first video data to the decoding module for decoding, and enhances the video transmission of the first video data.
The sending the processed second video data to the decoding module includes:
and performing signal enhancement or attenuation processing on the second video data and then sending the second video data to the decoding module.
In order to avoid power consumption caused by decoding the second video data in advance, after the processor downloads the second video data, the second video data is subjected to signal enhancement or reduction processing and then is sent to the decoding module, and after the second video data is subjected to signal enhancement or reduction processing, the decoding module cannot correctly receive or correctly decode the second video data, namely, the decoding module cannot decode the second video data, so that unnecessary power consumption caused by decoding the second video data under the condition that a user does not need to watch video contents before and after the target segment is prevented.
Specifically, the signal enhancing or reducing processing on the second video data includes:
and generating a video transmission control signal, and overlapping the video transmission control signal with the digital signal of the second video data.
After the processor acquires the second video data, the processor or the video transmission control module generates a video transmission control signal, the video transmission control signal is a continuous digital pulse signal, the digital pulse signal can be a positive pulse or a negative pulse, and the processor superposes the video transmission control signal and the digital signal of the second video data to realize signal enhancement or attenuation processing on the second video data. For example, the digital signal of the first video data is D1(V1), D2(V1),. D.,. D (n) (V1), the signal received by the decoding module is also D1(V1), D2(V1),. D.,. D (n) (V1), the digital signal of the second video data is D1(V2), D2(V2),. D.,. D (n) (V2), the video transmission control signal is D (p1), D (p2),. D (p2), and D (p (n)), then the signal generated after processing the second video data is (D1+ D (p1)) (V2), (D2+ D (p2)) (V2),. D., (D n) + (p2), and the decoding module cannot decode: (D1+ D (p1)) (V2), (D2+ D (p2)) (V2),., (D (n)) + D (p (n)) (V2), that is, the second video data cannot be decoded, and the video content corresponding to the second video data cannot be played, thereby reducing power consumption.
Referring to fig. 1 again, after the video playing method provided in this embodiment decodes and plays the first video data, the method further includes the following steps:
s300, after the preset instruction is obtained, the second video data is decoded and played.
The preset instruction is an instruction of video content sent by a user for playing the first preset time before the target segment or the second preset time after the target segment, and after the user finishes watching the target segment, if interest is generated in and after the plot of the target segment, the preset instruction may be sent, for example, the preset instruction is sent by clicking or dragging a progress bar, and after receiving the preset instruction, the terminal decodes and plays the second video data, specifically, the unprocessed second video data downloaded by the processor may be directly sent to the decoding module for decoding and playing, or the processed second video data may be decoded after signal restoration, and signal restoration of the processed second video data may be performed by the processor or performed by the decoding module, after the processed second video data is subjected to signal restoration, the decoding module can correctly decode the second video data, and output the decoded second video data to a screen for playing. Therefore, when the user selects to watch the video contents before and after the target segment, the corresponding video data is downloaded in advance, and real-time downloading is not needed, so that the time for downloading the data can be saved, smoother playing can be realized, and the watching experience of the user is improved.
In summary, the present invention provides a video playing method, when a user selects a designated target segment to watch, the video playing method downloads not only the video data of the target segment, but also the video data of a certain duration before the start time and after the end time of the target segment, so that the user can watch the content before and after the target segment with interest, and can play the content smoothly.
