It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
At present, when a user browses a large-scene video and performs operations such as rotation, translation, and scaling on a video picture, consumption of GPU and CPU resources of a Server end is increased, but system resources of a rendering Server (Server end) are limited. When the resources occupied by video display are too much, the resources occupied by picture acquisition and video coding are reduced, thus increasing the time delay of the overall browsing experience.
In view of the foregoing problems in the prior art, an embodiment of the present invention provides a video display method for network adaptive rendering. Fig. 1 is a schematic flow chart of a video display method of network adaptive rendering according to an embodiment of the present invention, and referring to fig. 1, first, steps of the video display method of network adaptive rendering according to an embodiment of the present invention are briefly described, which may specifically include the following steps:
And 102, the Server end receives the first signaling, and reduces the code rate and the resolution of the subsequent frame sent to the Client end.
Specifically, fig. 2 is an interaction schematic diagram of a Server and a Client according to an embodiment of the present invention, and referring to fig. 2, the Client includes a first signaling interaction unit, the Server includes a second signaling interaction unit, and the Client and the Server perform signaling interaction through the first signaling interaction unit and the second signaling interaction unit.
The Server end also comprises an acquisition unit, a data coding unit and a frame transmission unit. And the second signaling interaction unit is in communication connection with the frame transmission unit sequentially through the acquisition unit and the data coding unit. The acquisition unit is used for acquiring original data to be acquired by driving a display card of the Server end. And the data encoding unit is used for calling the hardware acceleration capability of the display card to encode and compress the original data. And the frame transmission unit is used for transmitting the encoded and compressed frame data to the Client terminal. In this embodiment, the frame transmission unit carries the data packet of the private protocol through the IP network, and the server sends the video data packet to the Client.
The Client terminal also comprises a frame receiving unit and a frame rendering unit. The first signaling interaction unit is in communication connection with the frame rendering unit through the frame receiving unit. The frame receiving unit is used for receiving the frame data sent by the Server end frame transmission unit and transmitting the frame data to the frame rendering unit. And the frame rendering unit is used for rendering the frame data to a display at a Client end.
Referring to fig. 1 and fig. 2, in the video display method of network adaptive rendering according to the embodiment of the present invention, first, when a user drags a video picture at a Client, the Client detects a video dragging instruction. And then, the first signaling interaction unit of the Client end sends a first signaling to the second signaling interaction unit of the Server end, and the code rate and the resolution ratio are required to be reduced. And finally, the Server end receives the first signaling, and reduces the code rate and the resolution of the subsequent frame sent to the Client end.
Compared with the prior art, the network self-adaptive rendering video display method and system provided by the embodiment of the invention have the following beneficial effects: when a user drags a video picture, the Server end reduces the resolution and code rate of sent frame data, reduces resources occupied by video picture display, reduces video browsing time delay and improves user experience.
At present, in the process of browsing a video scene, if the whole process time is fragmented, a video picture is in a static state at some time, and if a Server side continuously sends video data to a Client side in the static state of the video picture, network bandwidth is greatly wasted. To address this problem, as an optional embodiment, the video display method with network adaptive rendering provided by the present invention further includes:
and after detecting that the video image is still for more than the preset time, the Client end sends a second signaling to the Server end. For example, the preset time period may be 3 seconds, which is not specifically limited in this embodiment of the present invention.
And the Server end receives the second signaling, sends the high-definition frame of the current video picture to the Client end and suspends sending the subsequent frame.
In an application scenario of this embodiment, after the user stops the drag operation and the video image is still for 3 seconds, the first signaling interaction unit at the Client end sends the second signaling to the second signaling interaction unit at the Server end. And after receiving the second signaling, the Server end sends the high-definition frame of the current video picture to the Client end and then does not continue to acquire and send the video data. Meanwhile, the Server end informs a frame receiving unit of the Client end that the subsequent frame is not received after the high-definition frame sent by the Server end is received. And finally, rendering the high-definition picture by a frame rendering unit at the Client end and displaying the high-definition picture on a display at the Client end.
According to the video display method of the network self-adaptive rendering, when the video image is still, the Client terminal presents a high-definition image in a map mode, so that the situation that the video display occupies the network bandwidth for a long time is avoided.
On the basis of the foregoing embodiments, as an optional embodiment, after receiving the first signaling at the Server end and reducing the code rate and the resolution of the subsequent frame sent to the Client end, the method further includes:
when the Client terminal detects that the video dragging instruction stops, sending a third signaling to the Server terminal;
and the Server end receives the third signaling and sends frame data with normal code rate and resolution ratio to the Client end.
In an application scenario of this embodiment, after a user stops dragging a video image, the Client detects that a video dragging instruction stops, and immediately sends a third signaling to the Server, and the Server receives the third signaling and sends frame data with a normal code rate and a normal resolution to the Client, so that the Client can continue to play a high-definition image.
On the basis of the foregoing embodiment, fig. 3 is a block diagram of a video display system with network adaptive rendering according to an embodiment of the present invention, and referring to fig. 1, fig. 2, and fig. 3, the system includes a first signaling sending module 301 and a first signaling feedback module 302, where:

And the first signaling feedback module 302 is configured to receive the first signaling at the Server end, and reduce a code rate and a resolution of a subsequent frame sent to the Client end.
For details, how to perform video display of network adaptive rendering by using the first signaling sending module 301 and the first signaling feedback module 302 can refer to the above embodiments of the method, and details are not repeated here.
