Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted.
As shown in fig. 1, an embodiment of the present invention discloses a method for reducing cloud game delay, including the following steps:
and S10, acquiring a first operation signal of a key in the first equipment, and sending the first operation signal to the second equipment. Specifically, the first operation signal of the key in the first device may be acquired based on a capacitive sensor, a millimeter wave radar, image recognition, or infrared rays. The first device may be a local device at a user side, and the second device may be a server side. The first operation signal is a signal generated when the user touches the key. The key can be a mechanical key or a touch key. In an exemplary embodiment, the first device includes a handle and a display, and the key is a mechanical key on the handle. The first operation signal is generated when a key is touched, and the first operation signal includes key ID information for informing the second device of which key the user operates.
S20, the second device generates a first backup video stream based on the previous video stream, generates a first prediction video stream based on the previous video stream and the first operation signal, and feeds the first backup video stream and the first prediction video stream back to the first device. Specifically, the first backup video stream is used for displaying to the user through the first device after the first device determines that the prediction is wrong. The first predicted video stream is for display to the user via the first device after the first device determines that the prediction is correct.
The video streams are generated in time sequence. And if the previous prediction is correct, generating a first backup video stream corresponding to the current moment according to the predicted video stream at the previous moment, and generating a first predicted video stream corresponding to the current moment according to the predicted video stream at the previous moment and a first operation signal generated by touching a key. If the previous prediction is wrong, generating a first prediction video stream corresponding to the current time according to the backup video stream at the previous time as an initial picture of the prediction video stream at the current time; and replacing the predicted video stream at the previous moment with the backup video stream at the previous moment, and generating a first backup video stream corresponding to the current moment according to the replaced backup video stream.
S30, determining whether a second operation signal generated by continuously operating the key corresponding to the first operation signal in the first device is acquired within a first preset time, if yes, executing step S40: taking the first prediction video stream as a current moment video stream and displaying the current moment video stream; if not, go to step S50: and taking the first backup video stream as a current moment video stream and displaying the current moment video stream. Specifically, in step S10, if the first operation signal is generated by operating the key a, the first device determines whether the key a is to be operated for the next step within a first preset time. If the next operation is performed on the key a, the above-described step S40 is performed. If the next operation is not performed on the key a, the above step S50 is performed.
The first predictive video stream is a video clip which generates a corresponding game effect based on the second operation signal of the key, namely, the game effect generated when the key A is operated to the next step. The first backup video stream is a video clip which is generated corresponding to a game effect under the condition that the key is not continuously operated to generate the second operation signal, namely the game effect generated when the key A is not operated to the next step.
Illustratively, as shown in FIG. 2, at 0 ms: after the user touches the key a (i.e., operation 201), at 40 ms: the server receives a first operation signal corresponding to the touch key a (i.e., operation 202). At 60 ms: the user presses the key a (i.e., operation 203), and the server calculates a video stream corresponding to the pressed key a (i.e., operation 204), that is, the first predicted video stream and the first backup video stream; and starts to send the first predicted video stream and the first backup video stream to the local end respectively. At 100 ms: after receiving the video stream, the local end refreshes the game screen (i.e., operation 205). In this example, the first predictive video stream is the video stream of the game effect generated by key a being pressed. The first backup video stream is a video stream of a game effect generated when the key A is not pressed, and dynamic continuation is carried out on the basis of a game picture of the video stream at the previous moment, so that the game effect of basic dynamic functions is realized, such as river flowing, running of people and the like. The arrow directions in fig. 2 and 3 both indicate the directions in which the time increases from small to large in accordance with the time-series operation. The time labeled in fig. 2 and 3 only represents the interval time between two adjacent operations, for example, 40ms represents the interval of 40ms between two adjacent operations.
For the prior art scheme, as shown in fig. 3, at 0 ms: after the user touches key a (i.e., operation 301), at 60 ms: the user presses key a (i.e., operation 302). At 100 ms: the server receives a signal that key a is pressed (i.e., operation 303). At 120 ms: the server-side calculates that the completion key a is pressed down on the corresponding video stream (i.e., operation 304). At 160 ms: the local side receives the video stream sent by the server side and completes the refreshing of the game screen (i.e., operation 305). Therefore, in this example, compared to the prior art, the technical solution of the present invention directly detects whether the prediction is correct or incorrect, and then displays the corresponding video stream, directly refreshing the picture; the server does not need to wait for judging whether the prediction is correct or not, and then the corresponding video stream is sent, so that the time delay is favorably reduced. The delay of the cloud game is reduced from 160ms to 100ms, and the delay is obviously reduced.
In another embodiment of the present invention, as shown in fig. 4, the method further includes the steps of:
s60, the first device feeds back the identification information of the video stream displayed at the current time to the second device. The identification information of the displayed current video stream is used for representing that the current video stream is a first prediction video stream or the first backup video stream. When the prediction is correct, that is, the second operation signal is acquired, the current time video stream is the first prediction video stream, and at this time, the second device, that is, the server, knows that the prediction is correct, and then a prediction video stream at the next time and a backup video stream at the next time are respectively generated based on the first prediction video stream.
When the current time video stream is the first backup video stream, and the second device, i.e., the server, knows that the prediction error is due, the current time video stream is generated based on the current time video stream, the video segment corresponding to the first prediction video stream is replaced by the first backup video stream, and the second backup video stream corresponding to the next time is generated based on the replaced first backup video stream.
In this embodiment, as shown in fig. 4, after the first predicted video stream is displayed as the current time video stream in step S40, the method further includes:
s402, determining whether the duration of the second operation signal is greater than a second preset time, if so, executing step S403: and sending a long-press trigger signal to the second equipment.
S404, the second device generates a second predicted video stream and a second backup video stream corresponding to a next time based on the long press trigger signal and the first predicted video stream; and feeding back the second prediction video stream and the second backup video stream to the first device respectively.
S405, judging whether a third operation signal generated by continuing to operate the key corresponding to the long-press trigger signal in the first equipment is acquired within a third preset time; if yes, go to step S406: and taking the second prediction video stream as a video stream of the next moment and displaying the video stream. If not, go to step S407: and taking the second backup video stream as a video stream at the next moment and displaying the video stream.
If the duration of the second operation signal is not greater than the second predetermined time, the step S60 is executed.
The second preset time is longer than the first preset time, and the third preset time is longer than the second preset time.
In another embodiment of the present invention, a first pressure at which the first operation signal is generated is smaller than a second pressure at which the second operation signal is generated.
In another embodiment of the present invention, the first device includes a mechanical key, and a length of a first key stroke for generating the first operation signal is smaller than a length of a second key stroke for generating the second operation signal.
In another embodiment of the present invention, the first device includes a touch key, and a first touch area for generating the first operation signal is smaller than a second touch area for generating the second operation signal.
