It should be understood that the number of networks and devices in fig. 1 is merely illustrative. There may be any number of networks and devices as desired for an implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of an information push method according to the present application is shown. The information pushing method comprises the following steps:
Step 201, performing code stream conversion on the video data to obtain the video stream and the positioning information of the appearance article of the video stream.
In this embodiment, the execution body of the information pushing method (for example, the device 101 shown in fig. 1) may acquire video data from a background server (for example, the device 102 shown in fig. 1) of the video application, and perform code stream conversion on the video data to obtain a video stream and positioning information of the appearance article of the video stream.
The video data may include, among other things, a video stream and location information of the presence item of the video stream. Video streams are playable data including, but not limited to, television shows, movies, live broadcasts, short videos, and the like. The positioning information of the appearing items of the video stream is non-playable data for positioning the items appearing in the video stream, including but not limited to item names, item identifications, slice identifications to which the video frames of the appearing items belong, item appearance time points, slice start time points, and the like. The presence item may be an item that appears in the video stream, such as clothing, decorations, food, and the like. The slice to which the video frame in which the item appears belongs may comprise a series of consecutive video frames in the video stream, with the item appearing in at least one of the video frames.
For video frames in the video stream, not all the articles appear in each frame of video frame, but also not all the articles appear, so that the code stream coding processing is only carried out on the video frames where the articles with the positioning information are positioned, the video frame protocol is modified, and the positioning information is added in the original video frame protocol. The video data is added with the unplayable data and cannot be directly played, so that the video data is required to be subjected to code stream conversion, and the playable video stream and the unplayable positioning information are separated. The code stream conversion can adopt a static transcoding mode or a dynamic transcoding mode.
When the video frame protocol is modified, the modification modes are different for different protocol formats. Taking h.264 as an example, adding positioning information is supported by extending NAL (Network Abstraction Layer ) information of the video frame protocol. NAL may include NAL HEADER, NAL Extension, and NAL payload, among others. NAL HEADER may be used to store basic information of the video frames. NAL payload may be used to store a binary stream of video frames. NAL Extension may be used to store positioning information. NAL Extension is inserted into a video frame while not changing the data stored by the NAL payload to form a new video frame.
It should be noted that, the playback device typically plays the video stream while performing the transcoding. Therefore, in the video stream playing process, the positioning information of the appearing articles of the video stream can be obtained successively. Also, in order to facilitate searching, the obtained positioning information may be stored in a positioning information table.
Step 202, determining positioning information of the searched object in response to receiving an object searching instruction of the user.
In this embodiment, the user may issue an article search instruction to the execution body described above. In the case of receiving an item search instruction from a user, the execution body may determine positioning information for searching for an item.
In general, the user may issue an item search instruction during playback of the video stream, or may issue an item search instruction during playback of the video stream for the first time.
And when the video stream is played for the first time, the positioning information table can store the positioning information of all the articles in the video stream. Therefore, in the process of replaying the video stream, the item searched by the user may be the appearance item of the replayed video frame or the appearance item of the video frame which is not replayed yet.
For a user to issue an item search instruction in the process of playing a video stream for the first time, positioning information of an item appearing in a video frame that has been played in the process of playing the video stream for the first time may be stored in a positioning information table. Thus, the item searched by the user may only be the presence item of the video frame that has been played.
Generally, a user may issue an item search instruction in a variety of ways. Wherein, the more convenient way is to send out the article searching instruction by speaking the name of the searched article. At this time, the executing body may collect voice information of the user, identify the voice information, and determine the article name contained in the voice information. And if the object name is matched with the appearance object of the video stream, determining the matched appearance object as a search object. If the object name is not matched with the object appearing in the video stream, continuing to collect the voice information of the user. Since the positioning information of the appearance objects of the played video frames are stored in the positioning information table, the positioning information table generally stores the positioning information of a plurality of appearance objects. The presence item that matches the item name contained in the user's voice information is the user's search item. For example, the user speaks "watch", and the presence items corresponding to the location information table include a watch of brand a, clothing of brand B, and shoes of brand C, only the watch of brand a matches "watch", which is the user's search item.
Step 203, determining a play time point based on the positioning information of the searched object.
In this embodiment, the executing body may determine the play time point based on the positioning information of the search object.
In general, in the case where each frame of video frame is a complete map, the execution subject may take the occurrence time point of the search object contained in the positioning information as a play time point. However, due to coding factors, most video frames are not necessarily complete maps. In this case, the start time point of the slice to which the video frame of the search object included in the positioning information belongs needs to be set as the play time point. Wherein the first frame video frame in the slice is encoded based on the full map, and the subsequent video frames are encoded based on the change information of the earlier video frame. For example, if the second frame of video frame is added by one item from the first frame of video frame, only the added item information is encoded.
Step 204, jumping to the video frame corresponding to the playing time point to start playing.
In this embodiment, the executing body may jump to the video frame corresponding to the playing time point to start playing.
In general, in the case where the play time point is the occurrence time point of the search item, the first frame video frame skipped to may present the search item. When the playing time point is the starting time point of the slice to which the video frame of the searched article belongs, the first frame of the video frame jumped to does not present the searched article, and the searched article can be presented when the playing time point of the searched article is reached.
Step 205, query the push information of the search object and present the push information.
In this embodiment, the executing body may query the pushing information of the search object and present the pushing information.
In general, the executing body may query the push information of the search object through various approaches. For example, in the case of locally storing push information of a large number of items, the push information of the search item is locally searched. For another example, when the video application integrates the search function or the shopping function, a push information acquisition request for searching for an item is sent to a background server of the video application, and push information for searching for an item returned from the background server of the video application is received. For another example, a push information acquisition request of searching for an item is sent to a background server of the search application or shopping application, and push information of the search item returned by the background server of the search application or shopping application is received.
The pushing information may be a link for the user to browse the detailed information of the search item or a link for purchasing the search item. In general, push information may be presented on a currently playing video frame, particularly in the vicinity of a search item. The user may then perform a corresponding operation based on the push information to view the details of the search item or purchase the search item.
In some embodiments, in the case where the positioning information includes coordinate information, the executing body may determine a display area in the presence video frame based on the coordinate information of the search object, and display push information of the search object in the display area. The region corresponding to the coordinate information may be a display region.
According to the information pushing method provided by the embodiment of the application, firstly, code stream conversion is carried out on video data to obtain video streams and positioning information of the video streams on the appearance objects; then, in response to receiving an article searching instruction of a user, determining positioning information of the searched article; then determining a playing time point based on the positioning information of the searched object; and finally, jumping to a video frame corresponding to the playing time point to start playing, inquiring pushing information of the searched object, and presenting the pushing information. Through pre-burying the positioning information of the article in the video stream, when the article searching instruction of the user is identified, the user quickly jumps to the image of the article to be searched, and the pushing information of the article to be searched is automatically presented, so that the user can review the appearance scene of the article to be searched, the requirement that the user knows the information of the article interested in the user in detail is met, the article interested in the user can be conveniently purchased, and the operation cost of the user is saved.
With further reference to fig. 3, a flow 300 is shown that is yet another embodiment of an information push method according to the present application. The information pushing method comprises the following steps:
Step 301, performing code stream conversion on the video data to obtain the video stream and the positioning information of the appearance article of the video stream.
In response to receiving the item search instruction from the user, location information for searching for the item is determined 302.
In this embodiment, the specific operations of steps 301 to 302 are described in detail in steps 201 to 202 in the embodiment shown in fig. 2, and are not described herein.
Step 303, extracting the appearance video frame and appearance time point of the searched article from the positioning information of the searched article.
In this embodiment, the execution subject of the information push method (for example, the apparatus 101 shown in fig. 1) may extract the appearance video frame and the appearance time point of the search object from the positioning information of the search object.
In some embodiments, in the case that the positioning information includes an item name, an appearance video frame of the item, and an appearance time point, the execution entity may query the positioning information table for the appearance video frame and the appearance time point of the search item directly based on the name of the search item. The positioning information table may be used to store positioning information of the appearance article of the video stream obtained by performing code stream conversion on the video data.
In some embodiments, where the location information does not include the name of the item, the user cannot directly query the location information table based on the name of the searched item. To facilitate voice queries by the user, an item name table is established. Wherein the item name table may be used to store correspondence between item identifications and item names. The location information table may be used to store correspondence between item identifications and location information. The two are associated by the item identification. Specifically, the execution body may first query, in the item name table, an item identifier corresponding to an item name of the searched item; and then searching the appearance video frame and the appearance time point corresponding to the object identification of the searched object in the positioning information table. For ease of retrieval, the same items appearing in different slices may be pooled for storage, as shown in tables 1 and 2. Wherein table 1 shows a positioning information table and table 2 shows an article name table.
TABLE 1
TABLE 2
In step 304, the slice start time point at which the video frame appears is determined as the play time point.
In this embodiment, the execution body may determine a slice start time point at which a video frame appears as the play time point.
Step 305, jump to the play time point to fast play the slice to the appearance time point.
In this embodiment, the execution body may jump to the play time point to play the slice fast to the appearance time point. Generally, the playback speed from the point in time when the slice begins to the point in time when the slice occurs is relatively fast in order to quickly present the search item. And, starting playing from the slice start time point, the picture of the search object presented to the user can be ensured to be complete.
In some embodiments, where the search object appears in multiple slices of the video stream, the execution entity may prefer to jump to the slice with the earliest start time, or may list the multiple slices, and jump to the slice selected by the user.
Step 306, query the pushing information of the search object.
In this embodiment, the specific operation of step 306 is described in detail in step 205 in the embodiment shown in fig. 2, and will not be described herein.
Step 307, calculating the lattice coordinates of the searched objects based on the resolution of the playing device and the percentage coordinates of the searched objects.
In the present embodiment, in the case where the coordinate information is a percentage coordinate, the above-described execution subject may calculate the lattice coordinate of the search object based on the resolution of the playback apparatus and the percentage coordinate of the search object.
Since different playback devices have different screen resolutions, the coordinate information in the positioning information is a percentage coordinate in order to accommodate the different screen resolutions. And lattice coordinates are required for determining the display area, so that the percentage coordinates need to be converted into corresponding lattice coordinates. Specifically, the execution body may multiply the horizontal pixel value and the vertical pixel value of the resolution of the playback apparatus with the horizontal coordinate value and the vertical coordinate value of the percentage coordinate of the search object, to obtain the dot matrix coordinate of the search object.
For example, a video stream is played using a playback device having a resolution of a×b. If the percentage coordinates of the searched object are (x/a, y/B), the lattice coordinates of the searched object are (x a, y x B/B). Wherein a, B, A and B are positive integers, x is a positive integer not greater than a, y is a positive integer not greater than B, x/a and y/B are positive integers not greater than 1, x is a/a and y is B/B is a positive integer.
In general, the coordinate system of the percentage coordinates is the same as the screen coordinate system of the playback device, and is positive with the upper left corner as the origin, the right as the horizontal axis, and the downward as the vertical axis. At this time, the horizontal pixel value and the vertical pixel value of the resolution of the playing device are directly multiplied by the horizontal coordinate value and the vertical coordinate value of the percentage coordinate of the searched object, so that the lattice coordinate of the searched object can be obtained. Under special conditions, if the coordinate system of the percentage coordinates is different from the screen coordinate system of the playing device, the coordinate system of the percentage coordinates needs to be converted first to obtain converted percentage coordinates under the screen coordinate system; and correspondingly multiplying the horizontal pixel value and the vertical pixel value of the resolution of the playing equipment with the horizontal coordinate value and the vertical coordinate value of the conversion percentage coordinate of the searched article to obtain the dot matrix coordinate of the searched article.
Step 308, setting the area corresponding to the lattice coordinates as a display area, and displaying push information of the searched objects in the display area.
In this embodiment, the execution body may set an area corresponding to the lattice coordinates as a display area, and display push information of the search object in the display area. In this way, the push information is presented in the vicinity of the search object.
As can be seen from fig. 3, compared with the embodiment corresponding to fig. 2, the procedure 300 of the information push method in this embodiment highlights the step of determining the play time point and the step of determining the display area. Therefore, the scheme described in the embodiment starts playing from the slice starting time point, and the picture of the searched object presented to the user can be ensured to be complete. And the coordinate information in the positioning information is a percentage coordinate, and the corresponding lattice coordinate is obtained through coordinate conversion, so that the method is suitable for different screen resolutions of different playing devices.
With continued reference to fig. 4, a flow 400 of one embodiment of a video processing method according to the present application is shown. The video processing method comprises the following steps:
Step 401, identifying objects in the video stream, and determining the appearance objects in the video stream.
In this embodiment, the execution subject of the video processing method (e.g., the apparatus 101 shown in fig. 1) may perform item identification on the video stream to determine the presence item of the video stream.
In general, the executing entity may determine the presence item of the video stream in a variety of ways. In some embodiments, a person skilled in the art may perform item identification on the video stream, and input the identification result to the execution body. In some embodiments, the executing entity may split the video stream into a series of video frames and perform item identification on each frame of video frame to determine the presence item of the video stream.
Step 402, obtaining location information of the presence item.
In this embodiment, the executing body may acquire the positioning information of the present article. Wherein the positioning information of the appearing article is non-playable data for positioning the appearing article in the video stream.
In some embodiments, the positioning information may include coordinate information. Specifically, the executing body can perform position identification on the video stream to determine coordinate information of the appearing object; the coordinate information of the present article is added to the positioning information of the present article. Wherein the coordinate information may be determined by simulating the pilot video stream on the pilot device. Specifically, a pilot video stream is simulated on a first pilot device; then, carrying out position identification on the video stream to obtain dot matrix coordinates of the appearing article; and finally, determining the coordinate information of the appearing article based on the dot matrix coordinates of the appearing article.
In general, in the case where screen resolutions of most playback devices and trial playback devices are unified, the coordinate information may be lattice coordinates. However, in practical applications, different playback devices have different screen resolutions, and in order to accommodate the different screen resolutions, the coordinate information in the positioning information is a percentage coordinate. Specifically, the horizontal coordinate value and the vertical coordinate value of the dot matrix coordinates of the appearing object are correspondingly divided with the horizontal pixel value and the vertical pixel value of the resolution of the test seeding device, and the percentage coordinates of the appearing object can be obtained.
For example, a video stream is on-demand using a standard device with resolution a x b, and if the lattice coordinates of the emerging items captured on the on-demand device are (x, y), then the percentage coordinates of the emerging items are (x/a, y/b). Wherein a and b are positive integers, x is a positive integer not greater than a, y is a positive integer not greater than b, and x/a and y/b are positive integers not greater than 1.
It should be noted that the selection of the resolution of the trial playing device needs to be matched with the video resolution, for example, the selection above 720p is 16:9, and the following selection is 4:3. In this way, errors can be reduced as much as possible.
In some embodiments, the executing entity may further determine a slice start time point of the appearance video frame of the appearance article, and add the slice start time point of the appearance article to the positioning information of the appearance article.
And step 403, adding the positioning information of the appearance article to a corresponding video frame protocol to generate video data.
In this embodiment, the executing body may add the positioning information of the appearance article to the corresponding video frame protocol to generate the video data.
In general, the video frame protocol is modified by performing code stream encoding processing on the video frame where the article with the positioning information is located, so that the positioning information can be added in the original video frame protocol. When the video frame protocol is modified, the modification modes are different for different protocol formats. Taking h.264 as an example, adding positioning information is supported by expanding NAL information of a corresponding video frame protocol based on positioning information of an appearance article. NAL may include NAL HEADER, NAL Extension, and NAL payload, among others. NAL HEADER may be used to store basic information of the video frames. NAL payload may be used to store a binary stream of video frames. NAL Extension may be used to store positioning information. NAL Extension is inserted into a video frame while not changing the data stored by the NAL payload to form a new video frame.
The video processing method provided by the embodiment of the application comprises the steps of firstly, carrying out object identification on a video stream and determining the appearance object of the video stream; then obtaining the positioning information of the appearing article; and finally, adding the positioning information of the appearing article to a corresponding video frame protocol to generate video data, thereby realizing the addition of non-playable data in the video stream.
