In the prior art, in the process of playing content by a portable terminal device, if the content displayed on the portable device is shared to other devices for display, the portable device is required to perform screen acquisition and audio acquisition in the process of playing the content, and transmit the acquired images and audio codes to other devices for display in real time through a network; the content sharing process is easily limited by the self computing capability of the portable terminal equipment and the transmission capability of the local network, and the released picture can not achieve the high-fidelity effect of the original picture; based on this, the embodiment of the disclosure provides a content delivery method, a content delivery device and content delivery equipment.
Fig. 1 is a flowchart illustrating a method for content delivery according to an exemplary embodiment of the disclosure; the method is applied to a content delivery initiating device, and as shown in fig. 1, the method includes the following steps S101 to S102:
s101, after the content delivery initiating device is connected with a streaming media service, the content to be played is obtained and played, and if the content delivery initiating device detects the content delivery operation of a user, the content delivery initiating device responds to the content delivery operation and establishes an information transmission channel with a specified content receiving device.
In this embodiment, the content delivery initiating device establishes connection with the content delivery platform by establishing connection with the streaming media service, the content delivery platform issues the content to be played of the content delivery platform to the content delivery initiating device for playing through the streaming media service, and delivers the content to be delivered to the content receiving device for playing under the condition that the content delivery initiating device initiates content delivery. Illustratively, the content delivery platform may be a video playing platform (such as a video live platform) or a cloud streaming platform.
The content delivery initiating device obtains content to be played from a video playing platform or a cloud streaming platform for playing, if a user wants to deliver the content displayed by the content delivery initiating device to a content receiving device for displaying, the user triggers the content delivery initiating device to establish an information transmission channel with a specified content receiving device through a series of operations on the content delivery initiating device, and the specified content receiving device can be a terminal device which is specified by the user and previously establishes a binding relationship with the content delivery initiating device through a screen delivery service.
FIG. 2 is a schematic diagram illustrating a method of content delivery in accordance with an exemplary embodiment of the present disclosure; referring to the embodiment shown in fig. 2, the content delivery initiating device establishes an information transmission channel with the content receiving device through the screen delivery service. For example, a binding relationship between the content delivery initiating device and the content receiving device is established on the screen delivery service platform in advance, if the content delivery initiating device delivers content, the content delivery initiating device is first connected to the screen delivery service platform, and the content receiving device is also connected to the screen delivery service platform after being started, and the screen delivery service platform is used as an information transfer transmission channel between the content delivery initiating device and the content receiving device, so as to establish an information transmission channel between the content delivery initiating device and the content receiving device.
For example, the content delivery initiating device may be a mobile terminal device such as a mobile phone and a tablet computer, and may also be a head display (such as a virtual reality VR helmet, an augmented reality AR helmet, a mixed reality MR helmet, and the like). The content receiving device can be a set-top box, a television and other terminal devices.
S102, the content delivery initiating device transmits an acquisition identifier of the content to be delivered to the content receiving device through the information transmission channel, so that the content receiving device establishes connection with the streaming media service according to the acquisition identifier, and the streaming media service delivers the content to be delivered to the content receiving device for playing.
Continuing to refer to the above example, the content delivery initiating device sends the acquisition identifier of the content to be delivered to the screen delivery service platform, the screen delivery service platform further forwards the acquisition identifier of the content to be delivered to the content receiving device bound with the content delivery initiating device, and the content receiving device establishes connection with the streaming media service according to the acquisition identifier. Moreover, a content delivery initiating device can be preset on the screen delivery service platform to bind a plurality of content receiving devices, and when content delivery is carried out, the screen delivery service platform selects the content receiving devices meeting the conditions according to preset rules; the preset rule may be: for example, a device which is only successfully connected with the screen projection service platform is selected as a content receiving device, and for example, one or more devices with the highest priority are selected as the content receiving device according to the priority when a plurality of content receiving devices are successfully connected.
Optionally, the obtaining identifier of the content to be delivered may be a obtaining address of the content to be delivered, such as a Uniform Resource Locator (URL) address; the streaming media service may also include an identifier of the delivery initiating device, and then after the content receiving device establishes a connection with the streaming media service, the streaming media service delivers the content to be played sent to the content delivery initiating device to the content receiving device as the content to be delivered at the same time, or delivers the content to be played sent to the content delivery initiating device to the content receiving device as the content to be delivered after processing the content to be played.
Furthermore, in this embodiment, the content delivery initiating device responds to the content delivery operation of the user and establishes an information transmission channel with the content receiving device; the content delivery initiating device transmits the acquisition identifier of the content to be delivered to the content receiving device through the information transmission channel, and the content receiving device establishes connection with the streaming media service according to the acquisition identifier and directly acquires the delivered content for synchronous playing. Compared with the prior art, the content distribution method and the content distribution device have the advantages that the content distribution device is not limited by the computing capacity of the content distribution terminal device and the transmission capacity of the local network, the high fidelity of the distributed content received by the content receiving end is guaranteed, and the content distribution device and the content distribution method have the advantages of being simple, efficient and capable of improving user experience.
In a cloud streaming platform architecture, an application (such as a VR game application) runs on a cloud streaming platform, the cloud streaming platform performs a picture rendering operation in an application running process, encodes a rendered picture and an audio generated in the application running process, and transmits the encoded picture and the encoded audio to a terminal in a real-time audio/video stream form, and the terminal decodes and plays the real-time audio/video stream.
In an optional embodiment of the present disclosure, the content delivery initiating device is used as a playing terminal of the audio and video stream, and establishes a connection with the cloud streaming platform through a streaming media service, and obtains the content to be played (such as VR game video) from the cloud streaming platform for playing.
In this embodiment of the present disclosure, in the process of content delivery, the following step a10 is further included:
step A10, the content delivery initiating device sends the attitude information of the content delivery initiating device to the cloud streaming platform in real time, so that the cloud streaming platform renders the image of the content to be played in real time according to the attitude information.
Exemplarily, the cloud streaming platform determines a field angle corresponding to the posture information by referring to the posture information of the content delivery initiating device, and then renders a scene generated by application operation according to the field angle to obtain a picture of the content to be played, so that the picture rendered by the cloud streaming platform is adapted to the field angle of the user, and the user experience is improved. Or, the cloud streaming platform performs initial rendering on a scene generated by application operation according to an initially enlarged fixed field angle, and performs anisotropic cutting on an initially rendered picture according to the posture information (embodied by the current motion speed and the current motion direction) of the content delivery initiating device to obtain a picture of the content to be played.
In another optional embodiment of the present disclosure, in the content delivery process, the method further includes the following step B10:
step B10, the content delivery initiating device synchronizes the posture information of the content delivery initiating device to the content receiving device through the information transmission channel, so that the content receiving device adjusts the received picture of the delivered content and plays the adjusted picture with reference to the posture information of the content delivery initiating device.
In the embodiment of the disclosure, in the process of issuing the delivered content to the content receiving device by the cloud streaming platform, content displayed by the content receiving device and the content delivery initiating device may be inconsistent due to the influence of network delay, or the smoothness of the picture of the content receiving device may be degraded due to delay jitter, at this time, by synchronizing the posture information of the content delivery initiating device to the content receiving device, and adjusting the received picture of the delivered content by the content receiving device with reference to the posture information of the content delivery initiating device, such as performing Asynchronous Time Warping (ATW), the content displayed by the content delivery initiating device and the content receiving device may be synchronized or may tend to be synchronized as much as possible, and at the same time, the smoothness of the picture of the content receiving device may be improved.
In another embodiment of the disclosure, when the content to be played, which is obtained after the content delivery initiating device is connected to the streaming media service, is a panoramic video, because the content delivery initiating device (such as a VR helmet) may present pictures with different viewing angles in a moving process, in order to make a picture displayed by the content receiving device consistent with a picture displayed by the content delivery initiating device, the content delivery initiating device synchronizes posture information to the content receiving device through an information transmission channel in real time, the content receiving device adjusts and plays the picture of the delivered content with reference to the posture information of the content delivery initiating device, and further makes the viewing angle of the picture displayed by the content receiving device consistent with the viewing angle of the picture displayed by the content delivery initiating device.
Illustratively, in a specific application scenario, the content delivery initiating device is a VR headset, the content receiving device is a set top box, and if the VR headset is connected to a streaming service and a panoramic video stream is obtained from the streaming service for playing, the VR headset synchronizes posture information of the VR headset to the set top box, and when the set top box presents a picture delivered by the content delivery platform, the set top box adjusts the picture by using the posture information of the headset, so that a view angle of the picture viewed on the headset is consistent with a view angle of the picture displayed on the set top box.
In an embodiment of the present disclosure, the content receiving device and the content delivery initiating device may be different types of devices, and the content delivery initiating device and the content receiving device have different processing capabilities for video streams (mainly embodied in decoding and display performance); for example, referring to the above embodiment again, the content delivery initiating device is a VR helmet, the content receiving device is a set top box, and since the decoding and displaying capabilities of the set top box are lower than those of the VR helmet and the requirements of the set top box on the fluency of the picture are lower than those of the VR helmet, the streaming media service may set the frame rate of the content to be delivered to be lower than that of the content to be played, and then deliver the video streams of different paths to the content delivery initiating device and the content receiving device. Or, in the case that the network bandwidth of the content receiving device is poor, the frame rate of the content to be delivered may be set to be lower than the frame rate of the content to be played. For another example, the frame rate of the content to be delivered is set to be greater than or less than the frame rate of the content to be played sent by the streaming media service to the content delivery initiating device, by referring to the processing capabilities of the content delivery initiating device and the content receiving device on the video stream and the current network quality of the content receiving device.
FIG. 3 is a flow chart diagram illustrating a method of content delivery in accordance with an exemplary embodiment of the present disclosure; referring to the embodiment shown in fig. 3, an application runs on the cloud streaming platform 10, in the application running process, the cloud streaming platform 10 issues a content to be played, which is generated by the running of the application and is to be played by the content delivery initiating device, to the content delivery initiating device 20 for playing, in the content delivery process, if the processing capability of the content receiving device on the video stream is lower than that of the content delivery initiating device, the content to be played is subjected to frame dropping processing by the cloud streaming platform and then serves as a delivered content, and the content to be played and the delivered content delivered to the content receiving device, which are delivered by the cloud streaming platform to the content delivery initiating device, are not the same video stream. Illustratively, the cloud streaming platform reduces the frame rate of the content to be played from the original 60 frames per second to 30 frames per second as the delivered content through an encoder or other intermediate components.
Furthermore, in this embodiment, the content to be played is adjusted with reference to the video stream processing capability of the content receiving device and then delivered to the content receiving device, so that the requirement on the network bandwidth is reduced while the display effect of the content receiving device is ensured, and the user experience is improved.
In another optional embodiment of the present disclosure, if the performance parameters of the content delivery initiating device and the content receiving device are consistent, the performance parameters mainly include processing capability of a video stream of the device and current network environment quality; for example, if the content delivery initiating device and the content receiving device are both VR helmets having the same performance parameters and the network environment qualities of the content delivery initiating device and the content receiving device are equivalent, the content to be played, which is pushed to the content delivery initiating device by the cloud streaming platform, and the delivery content delivered to the content receiving device may be the same video stream, and then the content to be delivered of the content delivery initiating device is consistent with the content to be played of the device.
FIG. 4 is a flow chart diagram illustrating another method of content delivery in accordance with an exemplary embodiment of the present disclosure; referring to fig. 4, in the embodiment, an application runs on the cloud streaming platform 10, in a content delivery process, the cloud streaming platform 10 encodes a rendered picture and audio generated by the running of the application, the cloud streaming platform 10 simultaneously pushes the same video stream to the content delivery initiating device 20 and the content receiving device 30, and further, a content to be played and a delivered content delivered to the content receiving device, which are pushed by the cloud streaming platform to the content delivery initiating device, are the same video stream, so that the content receiving device can synchronously display the content currently displayed by the content delivery initiating device.
In the embodiment of the disclosure, in the content delivery process, the cloud streaming platform may send the same path of video stream or different paths of video streams to the content delivery initiating device and the content receiving device, so as to improve the environment adaptability of content delivery.
In this embodiment of the disclosure, the content delivery initiating device may establish a connection with a streaming media service through a first network, and acquire a content to be played from the cloud streaming platform to play the content; the content receiving device is connected with the streaming media service through a second network, and obtains the content to be delivered from the cloud streaming platform to play. Furthermore, in this embodiment, the content delivery initiating device and the content receiving device may be in different networks, which alleviates the problem of being limited by bandwidth when in the same network.
