It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for outputting information according to the present disclosure is shown. The method for outputting information comprises the following steps:
In step 201, the number of pixels occupied by the text to be output is calculated.
In this embodiment, the execution subject of the method for outputting information (e.g., the server shown in fig. 1) may issue text for interaction, such as the name of the star, or some number of the numbers. As shown in fig. 4a, sampling calculation can be performed according to a text such as a "mountain river" word, and the number of lighted pixels actually required by the "mountain river" word is calculated according to a rule that 16x 16 pixels can display one Chinese character or 2 letters. 53 pixels are required to be fully displayed (e.g., dots except for middle M in fig. 4 a).
Step 202, selecting participating audience members from a set of audience members based on the number.
In this embodiment, the calculated pixel points are the number of the lightened bullet screen information of the simulated scene [ fluorescence lifting ]. The audience can apply to participate in the interaction, and can use the default head portrait, and can also re-upload the head portrait (the head portrait is the detected qualified image and accords with the national regulation). The audience can click the [ fluorescence lifting ] application adding button in the live broadcasting room, call up the camera or album, select the picture or the video in 3s and upload as the head portrait. After the uploading is successful, the direct broadcasting room prompts the audience [ waiting for the star interaction ], and the audience is lifted together ].
If the number of the audience members who apply for participation in the interactive activity exceeds the required number of pixels, the participating audience members can be selected. A sufficient number of participating audience members may be selected at random, or may be selected in the order of the application.
If the participating audience members do not reach the desired number of pixels, then waiting for new audience members to join continues until the participating audience members reach the desired number of pixels, and step 203 is not performed. The number of audience segments may also be randomly selected.
Step 203, arranging the head portraits of each participating audience member according to the stroke shape of the text to generate barrage information.
In this embodiment, each head represents a pixel point, which is used to compose a stroke of the text, as shown in FIG. 4 a. The head portraits can be randomly selected for arrangement, and can be arranged according to a certain rule. For example, the dark pixels are scattered at different positions by arranging the colors, the brightness and the like of the head portrait, so that a certain stroke cannot be seen clearly due to the fact that the dark pixels are concentrated together.
Step 204, outputting bullet screen information in response to detecting the display opportunity.
In this embodiment, when the number of viewers applied reaches the required number of words to be lit, the card-lifting timing has several strategies:
And (3) identifying pictures or sounds extracted from the live video stream pictures, and triggering the [ fluorescence lifting ] display time when singing high tide. All audiences in the whole live broadcasting room can see the character pattern to light up, and a plurality of audience head images which just apply for playing cards are arranged on the character pattern.
The target scene may be detected as a presentation opportunity by an image recognition technique from a picture extracted from a live video stream picture, e.g., a lifting frame is raised. Keywords may also be detected from the extracted sounds by speech recognition techniques, and the presentation triggered when keywords are detected. Keywords may be pre-set according to lyrics, which are commonly chorused together by the audience at the time of the live concert.
The on-site staff triggers the card lifting time: under this scene, be fit for a plurality of performers and show on the same platform, then along with the steering of camera lens, the staff triggers the [ fluorescence of corresponding performer to lift the tablet ] show opportunity now.
The lighted text may be output by way of bullet screen information.
According to the method provided by the embodiment of the invention, atmosphere creation of the on-line concert direct broadcast room can be improved, the relativity between the vermicelli is improved, and the vermicelli can be provided with a display opportunity.
In some optional implementations of this embodiment, generating bullet screen information by arranging the avatars of each participating audience member in the stroke shape of the text includes: obtaining the geographic positions of the number of participating audience members; calculating the position weight of each participating audience member according to the geographic positions and live broadcast live positions of the plurality of participating audience members; for each participating audience member, the position of the head portrait of the participating audience member in the barrage information is distributed according to the position weight of the participating audience member, so that the position of the head portrait is closer to the center of the barrage information when the position weight is larger.
The server can calculate the straight line distance between the geographical position of the audience according to the geographical position information of each application (fluorescence name plate) (the user starts position information authorization or is acquired according to the network IP, base station and the like of the user at the time), and then calculates the straight line distance between the geographical position of the audience and the Shenzhen XXX company according to the current live broadcast position of the star (such as Shenzhen XX company, M point in fig. 4 a). And then quantized to a position weight of 0,1, which is the position distance parameter value of the viewer from the star, which is later used to display the actual position of the viewer in the lit font, as shown in fig. 4a, viewer B is closer to the live spot than a. The bigger the position weight is, the closer the position of the head portrait is to the center of the barrage information. The arrangement mode can shorten the distance between the audience and the site, so that the audience has more participation and the user experience is improved.
In some optional implementations of this embodiment, generating bullet screen information by arranging the avatars of each participating audience member in the stroke shape of the text includes: acquiring interaction records among the plurality of participated audiences; calculating the relation weight of each participated audience according to the interaction record; for each participating audience member, the position of the head portrait of the participating audience member in the barrage information is distributed according to the relation weight of the participating audience member, so that the position of the head portrait is closer to the center of the barrage information when the relation weight is larger.
The audience of each application (fluorescence playing card) may have knowledge or interaction, such as the relationship of adding friends to each other, or the relationship of focusing on each other, unidirectional focusing on each other, private chat recording, group chat recording, etc., and they apply for the application (fluorescence playing card) at the same time, then the server side calculates (for example, accumulates all interaction times) with all the application users according to each application user, and finally quantifies into a relationship weight value of [0,1] for displaying the actual position of the application user in the lighted font later. The more viewers interact with other viewers the higher the relationship weight. The greater the relation weight, the closer the position of the head portrait is to the center of the barrage information. The rewards obtained by the audiences with positive interaction are that the head portraits are close to the center of the barrage information, so that the interaction among the audiences can be promoted, and the enthusiasm of the interaction among the audiences is improved.
Alternatively, a weighted sum of the location weight and the relationship weight may be calculated as the total weight. The head portraits are arranged in a near-to-far mode from the center of the barrage information according to the sequence from the big to the small of the total weight. The arrangement mode considers the positions of audiences and the interactivity of the audiences, on one hand, the emotion among the fans is shortened, and on the other hand, the atmosphere of the concert is improved.
In some optional implementations of this embodiment, generating bullet screen information by arranging the avatars of each participating audience member in the stroke shape of the text includes: the head portraits of the participating audience members with the interactive records are distributed at adjacent positions. As shown in fig. 4a, viewers C and D have previously interacted with each other to assign their avatars to adjacent positions. Thus, the approach feeling between the vermicelli can be enhanced, the interaction effect is improved, and the audience can be personally on the scene to enjoy the field effect.
In some alternative implementations of the present embodiment, selecting a participating audience member from the audience member set based on the number includes: issuing a text of the interactive activity; receiving an interactive request of at least one audience, wherein the interactive request comprises a geographic location and any one of the following: a picture or video; selecting the number of participating audience members according to the sequence of receiving the interaction request; taking pictures or videos in the interaction request of the participating audience as the head portraits of the participating audience. The server issues text content which can generate barrage information in advance, and audiences can register to participate in interaction after seeing the text content. Clicking the participation option in the live broadcasting room pops up a window for uploading the picture or the video, and the audience confirms the submission after uploading the picture or the video. The audience can also manually submit the geographic position, or the authorization server obtains the geographic position through GPS positioning, IP address and the like. And the live broadcast software generates an interaction request according to the picture or the video and the geographic position and sends the interaction request to the server. The server selects the number of participating viewers according to the order in which the interactive requests are received. The pictures or videos submitted by the participating audience members are used as the avatars of the participating audience members. Preventing the head portraits of the audience from being lost or too dark, and leading to the generation of the bullet screen information. In addition, submitting short videos can generate dynamic barrage information, and each audience uploaded video is automatically played when the barrages are popped up.
With further reference to fig. 3, a flow 300 of yet another embodiment of a method for outputting information is shown. The flow 300 of the method for outputting information comprises the steps of:
in step 301, the number of pixels occupied by the text to be output is calculated.
Step 302, selecting participating audience members from a set of audience members based on the number.
Step 303, arranging the head portraits of each participating audience member according to the stroke shapes of the text to generate barrage information.
Step 304, outputting bullet screen information in response to detecting the display opportunity.
Steps 301-304 are substantially identical to steps 201-204 and are therefore not described in detail.
In response to detecting that the avatar of the participating audience member in the bullet screen information is clicked, an operation option to interact with the clicked participating audience member is output, step 305.
In this embodiment, in the process of displaying the [ fluorescence lift ], all viewers may click on the head portrait of any participant in the [ fluorescence lift ], and output operation options interacting with the clicked participant viewer. The clicker selects an operation from the operation options to interact with the clicked participating audience members.
Therefore, the connection between the vermicelli can be enhanced, the cohesive force between the vermicelli is improved, and the atmosphere of the direct seeding room is hotter.
In some alternative implementations of the present embodiment, the operational options include at least one of: viewing, paying attention, praise, private chat, collection, wheat linking, group photo and intimacy display. Through the interaction among the audience is enhanced in the plurality of modes, the viewing experience is improved in all aspects, the online performance can be realized in an immersive manner, and the same experience as that of the scene is obtained.
In some optional implementations of the present embodiment, the method further includes: outputting adjacent relation information to adjacent audiences if the adjacent audiences with geographic position distances smaller than a first preset value exist in the plurality of participated audiences; and if the number of interactive audiences with the interaction times larger than a second preset value exist in the plurality of participated audiences, outputting interaction relation information to the interactive audiences. If there are other participating viewers that are in close contact with the current viewer or that are geographically close, the viewer is also prompted to record XX and you together [ fluorescent listing ]. The audience can find other audiences closely related to the audience conveniently, and the live atmosphere can be enhanced by interaction.
With continued reference to fig. 4a, 4b, fig. 4a, 4b are a schematic illustration of an application scenario of the method for outputting information according to the present embodiment. In the application scenario of fig. 4a, 4b, the server issues the "fluorescence lift" content to be generated as "mountain river", and calculates that 53 participating spectators are required. A spectator who wants to participate in the card-lifting activity submits an interaction request, the server judges that 53 persons are less than the current time, the spectator is allowed to participate in the round of activity, and if 53 persons are exceeded, the spectator is informed of the next breakfast to participate in the next round of activity. Viewers allowed to participate in the event may upload images or videos as avatars. The server may also obtain a record of the geographic locations and interactions of the participating audience members and then calculate the location weight and relationship weight for each participating audience member. Some viewers upload unacceptable images or videos, and other viewers can supplement the images or videos. After collecting the head portraits of 53 participated spectators, the head portraits are arranged to generate bullet screen information of a 'mountain river' character. After detecting XXX or a live staff triggered playing display occasion in the lyrics of live broadcasting current sound, displaying [ fluorescence playing ] in a live broadcasting room in a bullet screen mode. Any audience (which can be a non-participating audience) can click on any head portrait in the figure (fluorescence lifting) and then perform interaction such as checking, focusing, praying, private chat, collection, wheat linking, group photo, intimacy display and the like.
