[0021] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0022] Figure 1 is a flow chart showing a channel switching method according to an embodiment of the present invention. Figure 1 As shown, the channel switching method in the embodiment of the present invention has the following steps.

[0023] Step S110, in response to a channel switching signal, releasing the association between the display window and the image texture corresponding to the preset player of the previous channel, wherein the channel switching signal carries information of a target channel to which the previous channel is to be switched.

[0024] Step S120: establishing an association relationship between the image texture corresponding to the preset player of the target channel and the display window.

[0025] Step S130, using a pre-created rendering component, rendering the image texture associated with the display window.

[0026] Step S140: sending the image frame of the target channel obtained by rendering to the display window to switch to the target channel.

[0027] The image texture corresponding to the preset player of the previous channel and the image texture corresponding to the preset player of the target channel are image textures generated in advance by the texture component in the rendering component.

[0028] In one embodiment, the channel address includes a target channel and multiple adjacent channel addresses. The previous channel and the target channel can be two adjacent channel addresses or two non-adjacent channel addresses, as long as the image texture corresponding to the player of the target channel exists when switching from the previous channel to the target channel.

[0029] According to the channel switching method of an embodiment of the present invention, when the user selects a target channel, the unique association between the display window and the image texture corresponding to the player of the previous channel is released, a unique association between the display window and the image texture associated with the selected channel is established, and the uniquely associated image texture is rendered to the window for display, so as to switch the previous channel to the target channel.

[0030] In the embodiment of the present application, the player of the previous channel and the player of the target channel are respectively associated with texture components, and when the image texture obtained by the associated texture components is uniquely associated with the display window, the rendering to the display window is performed. That is to say, in the channel switching method of the embodiment of the present application, when a channel is selected, the image texture associated with the selected channel is rendered and displayed, and the image texture not associated with the window is not subjected to image rendering processing and drawing to the window, thereby improving the channel switching speed and reducing the channel switching time.

[0031] Furthermore, according to the channel switching method of the present application, for image textures that are not associated with the display window, there will be no CPU and GPU occupancy and performance consumption due to image processing during rendering, thereby reducing the resource usage of the system CPU and GPU.

[0032] In one embodiment, the channel switching method further includes the following steps.

[0033] S21, using a pre-created multi-channel player to decode the image data of multiple channels to obtain decoded data of each channel player.

[0034] In the embodiment of the present application, the player may be an application object having a function of playing multimedia data, and the player may parse, decode, render and prepare multimedia data in the channel. The multimedia data in the embodiment of the present application at least includes video stream data. For example, the multimedia data may include not only video stream data, but also at least one of audio stream data and image data.

[0035] S22, creating multiple texture components in the pre-created rendering component, and establishing an association relationship between each player and one of the multiple texture components.

[0036] In the embodiment of the present application, the image texture is an internal image processing object based on the Open Graphics Library (OpenGL), including vertex coordinate information and color depth information, etc. The texture component can be understood as a container for caching image data (such as decoded data of a player). The player is associated with one of the pre-created multiple texture components, and the decoded data of the player is buffered in the associated texture component. The texture component can render the decoded data of the associated player into a corresponding image texture.

[0037] S23, processing the decoded data of each player in the associated texture component to obtain the image texture corresponding to the player of each channel.

[0038] In this embodiment, before entering a channel, multiple players can be created first, and each player is configured with a channel address for playback. Create a rendering component and multiple texture components (Surface Texture), associate the player with the texture component, and the decoded data of the player will be transmitted to the internal buffer of the texture component to obtain the image texture corresponding to the player. When the user selects a channel, the image texture corresponding to the player of the channel will be associated with the display window, and the image texture will be rendered and displayed in the window. The renderer in the embodiment of the present invention, also called a rendering component, is used to render the image texture corresponding to the player.

[0039] For ease of understanding, the following Figure 2-Figure 4 , describing a channel switching method of an exemplary embodiment of the present application. Figure 2 A schematic diagram showing the architecture of a channel switching method according to an embodiment of the present application.

[0040] like Figure 2 As shown, the architecture may include: multiple players pre-created in the application 10, such as player 1, player 2,..., player n, multiple texture components 20 pre-created in the rendering component 20, such as texture component 1, texture component 2,..., texture component n, and a display window 30.

[0041] exist Figure 2 In the embodiment, each player can decode the multimedia data in the corresponding channel according to the configured channel address to obtain the decoded data of each player.

[0042] Continue to refer Figure 2 Before entering the channel, you can create multiple players, each of which can be configured with a channel address for playback. Create a rendering component and multiple texture components. The rendering component 20 can be used to render the image texture corresponding to the player.

[0043] In the embodiment of the present invention, each player is associated with a texture component, and the decoded data of the player is transmitted to the internal buffer of the texture component to obtain the image texture corresponding to the player, such as image texture 1, image texture 2, ..., image texture n. When the user selects a channel, the image texture corresponding to the player of the channel is associated with the display window, and the image texture is rendered and displayed in the window.

[0044] Figure 3 FIG. 1 is a flow chart showing a channel switching method according to an exemplary embodiment of the present application. Figure 3 As shown, the channel switching method in this embodiment may include the following steps.

[0045] S301, the user enters the terminal application.

[0046] After entering the terminal application, you can create an image display window, which can be used to display the video screen.

[0047] S302, creating a multi-channel player.

[0048] In this step, each player decodes the audio and video streams of the default channel and adjacent channels.

[0049] S303, creating a multi-channel texture component.

[0050] In this step, a multi-pass texture component can be created using a rendering component.

[0051] S304, associating the player with the texture component.

[0052] In this step, each player can be uniquely associated with a texture component, and the decoded data of the player will be transmitted to the corresponding texture component for buffering. The obtained image texture corresponding to the player can be used for subsequent rendering processing.

[0053] S305, associating the current image texture with the window.

[0054] In this step, the image texture corresponding to the player of the current playing channel is associated with the window, an association relationship is established, and a rendering operation is performed on the image texture associated with the window to obtain rendering information corresponding to each image texture.

[0055] S306, rendering the image to the window.

[0056] In this step, the display window is refreshed periodically, and the rendering information corresponding to the image texture currently associated with the display window is drawn to the display window for display.

[0057] S307, the user switches channels.

[0058] In this step, in response to the channel being switched, the window is disassociated from the original image texture after switching to the new channel, and is associated with the image texture corresponding to the new channel.

[0059] S308: The display window is disassociated from the original image texture and associated with a new image texture.

[0060] In this step, the image texture that is no longer associated with the display window is no longer rendered, and only the image texture newly associated with the display window is rendered.

[0061] S309, rendering the image to the window.

[0062] In this step, the display window is refreshed periodically, and the rendering information in the new image texture associated with the display window is drawn to the window for display.

[0063] In this embodiment, a model of multiple players and one rendering component is adopted, which can reduce the use of rendering components. For undisplayed windows and player objects, CPU and GPU occupancy and performance consumption caused by image processing during rendering will not be generated, thereby greatly reducing the resource usage of the system CPU and GPU.

[0064] Figure 4 A timing diagram of a channel switching method according to another exemplary embodiment of the present application is shown. For the convenience of description, player 1 and player 2 among multiple players are taken as examples to introduce the specific steps of switching from player 1 to player 2. It should be understood that the players in the embodiment of the present application are not limited to player 1 and player 2. In a multi-channel player, the channel switching method can be used in the scheme of switching from the previous player to the current player, and the embodiment of the present application will not be repeated.

[0065] like Figure 4 As shown, in this embodiment, the channel switching method may include the following steps.

[0066] S401, such as Figure 4As shown in "Creating Playback Channel 1", create player 1, configure the address of channel 1, and decode the multimedia data in channel 1.

[0067] In an embodiment of the present application, if channel 1 is the first channel selected by the user after entering the application, multiple players are pre-created before entering the channel.

[0068] S402, such as Figure 4 As shown in “Creating Playback Channel 2”, create player 2, configure the address of channel 2, and decode the multimedia data in channel 2.

[0069] Through the above steps S401 and S402, multiple players are created for playing multiple channels, and each player is used to play one of the channels. Specifically, each player can decode the multimedia data in one channel to obtain the decoded data of each player.

[0070] S403, such as Figure 4 As shown in "Creating Texture 1 and Texture 2", create texture component 1 and texture component 2. Among them, multiple texture components can be created in the rendering component for screen rendering.

[0071] S404, such as Figure 4 As shown in “Associating Texture Component 1”, a unique association relationship between player 1 and texture component 1 is established.

[0072] S405, such as Figure 4 As shown in “Associating Texture Component 2”, a unique association relationship between player 2 and texture component 2 is established.

[0073] Through the above steps S404 and S405, the decoded data of each player will be transmitted to the associated texture component for buffering, and the image texture corresponding to the player playing each channel will be obtained.

[0074] S406, such as Figure 4 As shown in the "Image Texture 1 Association Window", when channel 1 is selected, image texture 1 corresponding to the player of channel 1 is associated with the display window.

[0075] S407, such as Figure 4 As shown in "Window Refresh Display", when the display window is refreshed, the image texture 1 corresponding to the player of channel 1 is rendered, and the rendering data obtained by the rendering process is drawn to the display window for display.

[0076] In this step, the image texture corresponding to the target channel is associated with the window, and the image texture associated with the display window is rendered and displayed.

[0077] S408, such as Figure 4As shown in “Select Image Texture 2”, when the user selects channel 2, texture component 2 associated with player 2 of channel 2 is determined.

[0078] S409, such as Figure 4 As shown in the "Image Texture 2 Association Window", when channel 2 is selected, the display window and the image texture corresponding to the player of channel 1 are disassociated, and an association relationship is established between the display window and the image texture corresponding to the player of channel 2.

[0079] In this step, the association relationship between the original image texture and the display window is released, and the association relationship between the image texture corresponding to the switched channel and the display window is established.

[0080] S410, such as Figure 4 As shown in "Window Refresh Display", when the display window is refreshed, the image texture 2 corresponding to the player of channel 2 is rendered, and the rendering data obtained by the rendering process is drawn to the display window for display.

[0081] In this embodiment, the video application can create multiple players for decoding the video of the channel, configure adjacent channels for playback, and create a display window for displaying the current playback channel screen, establish an association relationship between each player and a texture component, and transmit the image texture corresponding to the player of the target channel to the window for rendering and display. The image textures of the remaining channels are not associated with the display window. When switching to an adjacent channel for playback, the image texture corresponding to the player of the original channel is disassociated from the window, and the image texture corresponding to the player of the channel is rendered and displayed through the associated window. Since the image texture that is not associated with the window does not perform image rendering processing and drawing operations, the resource consumption of the CPU and GPU can be reduced.

[0082] In one embodiment, the player of the previous channel and the player of the target channel are two players in a pre-created multi-channel player.

[0083] In this embodiment, if the number of multiple players reaches a player number threshold, after releasing the unique association between the display window and the image texture corresponding to the player of the previous channel, the channel switching method may further include the following steps.

[0084] S51, releasing the player of the previous channel, and canceling the association between the player of the previous channel and the texture component corresponding to the player of the previous channel.

[0085] S52, creating a new player, and using the new player to decode the image data of the designated channel to obtain decoded data of the new player, wherein the designated channel is a channel of the preset multiple channels whose image data has not been decoded.

[0086] S53, establishing an association relationship between the new player and the disassociated texture component.

[0087] S54, processing the decoded data of the new player in the associated texture component to obtain the image texture corresponding to the player of the channel corresponding to the new player.

[0088] In this embodiment, due to the performance constraints of the terminal device, the number of pre-created players is limited. When the number of pre-created players reaches the player number threshold, when the user switches channels, after releasing the unique association between the display window and the image texture corresponding to the player of the previous channel, it is also necessary to remove the corresponding player and add a new player to achieve switching between multiple channels under performance constraints.

[0089] In one embodiment, the previous channel and the target channel are adjacent channels in a preset plurality of channels, and the plurality of channels have a predetermined first order; the player of the previous channel and the player of the target channel are two players in a pre-created multi-channel player, and the multi-channel player has a predetermined second order.

[0090] In this embodiment, the playing channels in the application can generally be presented as a channel list, and the channel list display can be exemplarily displayed in a queue manner. Accordingly, since each channel can be configured with a player, the player can be added or removed in a queue manner, and the predetermined queue order of the pre-created multi-channel players is used as the second sorting.

[0091] In one embodiment, when the number of pre-created multi-channel players is greater than the player number threshold, and the target channel is adjacent to the previous channel, when the channel is positively selected according to the first sorting, after step S110, the channel switching method may further include the following steps.

[0092] S61, according to the predetermined second order, releasing the first player in the multiple players, and releasing the association between the first player and the associated texture component.

[0093] S62, creating a new player, and using the new player as the last player in the multi-channel player according to the predetermined second sorting.

[0094] S63, establishing an association relationship between the last player and the disassociated texture component.

[0095] S64, processing the decoded data of the last player in the associated texture component to obtain the image texture corresponding to the player of the channel corresponding to the last player.

[0096] In this embodiment, when the channel switching is forward switching according to the predetermined first order, the head player can be released, the association with the corresponding texture can be cancelled, and a newly created player can be added from the end of the team, and the texture component that was cancelled from the previous head player can be associated.

[0097] In another embodiment, when the number of pre-created multi-channel players is greater than the player number threshold, and the target channel is adjacent to the previous channel, when the channel is reversely selected according to the first sorting, after step S110, the channel switching method may further include the following steps.

[0098] S71, according to the predetermined second sorting, releasing the last player in the multi-channel players, and disassociating the last player from the associated texture component.

[0099] S72, creating a new player, and using the new player as the first player in the multi-channel player according to the predetermined second order.

[0100] S73, establishing an association relationship between the first player and the disassociated texture component.

[0101] S74, processing the decoded data of the first player in the associated texture component to obtain the image texture corresponding to the player of the channel corresponding to the first player.

[0102] In this embodiment, when the channel switching is reversed according to the predetermined first order, the tail player can be released, the association with the corresponding texture can be cancelled, and the newly created player can be added from the head position and associated with the image texture that was previously cancelled from the tail player.

[0103] For ease of understanding, the following Figure 5 , describing the schematic diagram of the release and creation process of the player during the channel switching process when the number of playback channels reaches the upper limit. Figure 5 The channel switching process of another exemplary embodiment of the present application is shown.

[0104] In this embodiment, the channel switching method may specifically include the following steps.

[0105] S81, pre-create multiple players.

[0106] In this step, the number of the multiple players is less than or equal to the predetermined player data threshold. In practical applications, the number of the multiple players can be set according to actual conditions, and the embodiment of the present application does not make a specific limitation.

[0107] S82, pre-create multiple texture components, associate each player with a texture component, and use the texture component to process the decoded data of the associated player to obtain the image texture corresponding to the player of each channel.

[0108] In this step, the same number of texture components can be created according to the number of created players. Taking 4-way players as an example, through the above steps S81 and S82, a player queue is pre-created, and the player queue can include 4-way players, and 4-way texture components are pre-created, and each texture component is associated with one player.

[0109] As an example, in the queue sorting of the channel list, the first sorting of the channels in the forward direction may be, for example, the order from channel 1, channel 2, channel 3 to channel 4, and the first sorting of the channels in the reverse direction may be the order from channel 4, channel 3, channel 2 to channel 1. Figure 5 In the embodiment, the channels are switched in a positive direction according to the first sequence, for example, they may be switched from top to bottom.

[0110] S83, select player 2.

[0111] S84, establishing an association relationship between the display window and the image texture 2 from the texture component 2, thereby rendering the image texture corresponding to the player 2, obtaining and displaying the playback picture of the channel 2 in the display window.

[0112] S85, selecting player 3, that is, when switching from player 2 to player 3, the unique association between the display window and image texture 2 is released, and the association between player 1 and texture component 1 is released.

[0113] S86, add the newly created player 5 from the end of the player queue, and establish an association relationship between player 5 and texture component 1.

[0114] In this step, player 5 is a newly created player, and texture component 1 is a texture component that is disassociated from the display window and is not associated with the player.

[0115] S87, establishing an association relationship between the display window and the image texture 3 from the texture component 3, rendering the image texture corresponding to the player 3, obtaining and displaying the playback picture of the channel 3 in the display window.

[0116] In this embodiment, if the number of pre-created playback channels reaches the device upper limit, a queue method can be used to add and remove players to achieve switching between multiple channels under performance constraints, improve channel switching speed, and reduce CPU and GPU occupancy and performance consumption by reducing the number of rendering times.

[0117] Usually, when switching channels, if you recreate the player and optimize the player start-up speed to improve the channel switching effect, you need to switch to a new player to switch channels. Since the player start-up time is mostly more than 500ms, during the channel switching process, users can clearly see the black screen. If the network quality is poor, the channel start-up time will be extended, and the viewing experience will be significantly reduced.

[0118] If multiple players and multiple rendering components are created in advance and channels are switched by directly switching the display and hiding of the players and corresponding display windows, a large amount of CPU and GPU resources will be consumed due to the creation of multiple players, and the device may easily heat up due to a large amount of calculations.

[0119] In the description of the above embodiments, the player, rendering component, texture component and display window involved can all be implemented in the form of software code.

[0120] According to the channel switching method of the embodiment of the present application, multiple players are created in advance, channel addresses are configured for decoding, and a rendering component and multiple texture components are created. Each player can be associated with a texture component, and the decoded data of the player will be transmitted to the internal buffer of the associated texture component. When the user selects a channel, the image texture corresponding to the player of the channel is associated with the display window, and the image texture associated with the display window is rendered and displayed in the window.

[0121] This method adopts a model of multiple players and one rendering component, reducing the use of rendering components. Undisplayed windows and player objects will not generate CPU and GPU occupancy and performance consumption due to image processing during rendering, greatly reducing the resource usage of the system CPU and GPU. After testing, this method reduces the CPU occupancy by at least 30% compared with the original N-channel playback and N-channel rendering, thereby reducing CPU consumption, improving system resource utilization, shortening the user's switching time, and realizing frame-level channel switching, thereby improving the user's viewing experience.

[0122] The channel switching device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Figure 6 FIG. 2 shows a schematic diagram of the structure of a channel switching device provided according to an embodiment of the present invention. Figure 6 As shown, the channel switching device may include the following modules.

[0123] The disassociating module 210 is used to disassociate the display window from the image texture corresponding to the preset player of the previous channel in response to a channel switching signal, wherein the channel switching signal carries information of a target channel to be switched from the previous channel.

[0124] The association module 220 is used to establish an association relationship between the image texture corresponding to the preset player of the target channel and the display window.

[0125] The rendering processing module 230 is used to use a pre-created rendering component to perform rendering processing on the image texture associated with the display window.

[0126] The image display module 240 is used to send the image of the target channel obtained by rendering to the display window to switch to the target channel.

[0127] The image texture corresponding to the preset player of the previous channel and the image texture corresponding to the preset player of the target channel are image textures generated in advance by the texture component in the rendering component.

[0128] In one embodiment, the channel switching device may further include the following modules.

[0129] The channel decoding module is used to decode the image data of multiple channels by using the pre-created multi-channel players to obtain the decoded data of each channel player.

[0130] The texture association module is used to create multiple texture components in a pre-created rendering component and establish an association relationship between each player and one of the multiple texture components.

[0131] The texture processing module is used to process the decoded data of each player in the associated texture component to obtain the image texture corresponding to the player of each channel.

[0132] In one embodiment, the player of the previous channel and the player of the target channel are two players in a pre-created multi-channel player. The channel switching device may further include the following modules.

[0133] The player release module is used to release the player of the previous channel if the number of multiple players reaches a player number threshold, after releasing the unique association between the display window and the image texture corresponding to the player of the previous channel, and to release the association between the player of the previous channel and the image texture corresponding to the player of the previous channel.

[0134] The player creation module is used to create a new player and use the new player to decode the image data of the specified channel to obtain the decoded data of the new player. The specified channel is a channel with undecoded image data among the preset multiple channels.
