The technical solution of the present invention will be described in detail below with specific examples. Several of these embodiments may be combined in some embodiments, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a first flowchart illustrating a video information processing method according to the present application. As shown in fig. 1, a video information processing method according to some embodiments of the present application includes:
s101: and acquiring the network occupancy rate and the video processing mode in the process of receiving the first video code stream.
In some embodiments, the execution subject of the embodiments of the present application is a processor in a display device.
In some embodiments, the video processing mode refers to a generation mode of a received network device code stream, and the video processing mode is a frame skipping processing mode or a non-frame skipping processing mode.
The non-frame-skipping processing mode is a generation mode that the network equipment generates a video code stream frame by frame according to the original data. For example: the data frames contained in the original data are data frame 1, data frame 2, data frame 3, data frame 4 and data frame 5 in sequence, and the video code stream contains a first video frame code stream corresponding to data frame 1, a second video frame code stream corresponding to data frame 2, a third video frame code stream corresponding to data frame 3, a fourth video frame code stream corresponding to data frame 4 and a fifth video frame code stream corresponding to data frame 5 in sequence in a non-frame-skipping processing mode.
The frame skipping processing mode is a generation mode of generating a video code stream by N frames according to original data by network equipment, wherein N is more than or equal to 1. For example: the data frames contained in the original data are data frame 1, data frame 2, data frame 3, data frame 4, data frame 5, data frame 6 and data frame 7 in sequence, and the video code stream contains a first video frame code stream corresponding to data frame 1, a third video frame code stream corresponding to data frame 3, a fifth video frame code stream corresponding to data frame 5 and a seventh video frame code stream corresponding to data frame 7 in sequence in a frame skipping processing mode; or, the video code stream includes a first video frame code stream corresponding to the data frame 1, a second video frame code stream corresponding to the data frame 2, a fourth video frame code stream corresponding to the data frame 4, and a sixth video frame code stream corresponding to the data frame 6 in sequence in the frame skipping processing mode; or, the video code stream includes a first video frame code stream corresponding to the data frame 1, a third video frame code stream corresponding to the data frame 3, a fifth video frame code stream corresponding to the data frame 5, and a seventh video frame code stream corresponding to the data frame 7 in sequence in the frame skipping processing mode.
In some embodiments, the network device sends the video code stream to the display device, and also sends an identifier representing a processing mode according to a generation mode of the code stream, and the display device determines whether the currently received code stream is a frame skipping processing mode or a non-frame skipping processing mode according to the identifier of the video processing mode, and how many frames are skipped during frame skipping processing. The mark of the representation processing mode sent at the beginning is a non-frame-skipping processing mode, and when frame skipping processing is carried out, the N-frame-skipping processing mode is determined according to the number of data frames at the interval of two video frame code streams.
In some embodiments, the network device may adjust the frame skipping processing mode according to the network occupancy rate, and adjust the number of data frames of the two video frame code stream intervals according to the current processing mode and the network occupancy rate.
In some embodiments, the display device determines a video processing mode according to a current video processing identifier, and updates the video processing mode according to the video processing mode and the network occupancy rate, wherein the video processing identifier is determined according to a target frame skipping value sent by the display device. At the beginning, the display device does not send the target frame skipping value, so the display device side video processing identifier represents that the video data received by the display device side is in a non-frame skipping processing mode, when the video processing mode is in the non-frame skipping processing mode, the current target frame skipping value is 0, and the target frame skipping value is determined according to the network occupancy rate and the current target frame skipping value. When the network occupancy rate is increased, improving a frame skipping value of frame skipping processing, for example, determining that a target frame skipping value is 1, and sending the target frame skipping value to a network device, wherein data frames contained in original data of the network device are a data frame 1, a data frame 2, a data frame 3, a data frame 4, a data frame 5, a data frame 6 and a data frame 7 in sequence, and according to the target frame skipping value 1, a video code stream contains a first video frame code stream corresponding to the data frame 1, a third video frame code stream corresponding to the data frame 3, a fifth video frame code stream corresponding to the data frame 5 and a seventh video frame code stream corresponding to the data frame 7 in sequence in a frame skipping processing mode; and the display equipment re-determines the current frame skipping value according to the target frame skipping value 1 and updates the current video processing identifier representing the video processing mode into a frame skipping processing mode. When the current video processing identifier of the display device represents that the video processing mode is a frame skipping processing mode, the current target frame skipping value is 1, the target frame skipping value is determined according to the network occupancy rate and the current target frame skipping value, when the network occupancy rate is increased, the frame skipping value of the frame skipping processing is increased, for example, the target frame skipping value is determined to be 2, the target frame skipping value is sent to the network device, the data frames contained in the original data of the network device are a data frame 1, a data frame 2, a data frame 3, a data frame 4, a data frame 5, a data frame 6 and a data frame 7 in sequence, and according to the target frame skipping value 2, the video code stream contains a first video code stream corresponding to the data frame 1, a fourth video code stream corresponding to the data frame 4 and a seventh video code stream corresponding to the data frame 7 in sequence under the frame skipping processing mode.
S102: and determining a target frame skipping value according to the network occupancy rate and the video processing mode.
In one possible design, the method for determining the target frame skipping value according to the network occupancy rate and the video processing mode includes:
if the video processing mode is a non-frame-skipping processing mode, determining a target frame-skipping value according to the network occupancy rate, the first occupancy rate threshold value and a preset frame-skipping value;
and if the video processing mode is a frame skipping processing mode, determining a target frame skipping value according to the network occupancy rate, the first occupancy rate threshold value, the preset frame skipping value and a first frame skipping value (current frame skipping value) corresponding to the frame skipping processing mode.
In some embodiments, the first occupancy threshold may be 50%, 60%, etc., the preset frame skipping value may be 1, 2, 3, etc., and the first frame skipping value may also be 1, 2, 3, etc.
S103: and sending the target frame skipping value to the network equipment.
In some embodiments, the processor may directly send the target frame skipping value to the network device, and may also send a code stream data request to the network device, where the code stream data request includes the target frame skipping value.
In some embodiments, the bitstream data request may further include an identifier and a network address of the display device, a movie name corresponding to the first video bitstream, and the like.
The network device may process the original code stream according to the received target frame skipping value, and in some embodiments, the first video code stream may only be a video code stream in a non-frame skipping processing mode, or may be a video code stream in a current frame skipping value.
In some embodiments, the target frame skipping value is that the frame rate of a video frame in a video code stream received by the display device conforms to the refresh rate of the display screen, and the frame rates of the video frames in the video code streams corresponding to different target frame skipping values are different and the refresh rates of the corresponding display screens are also different.
S104: and receiving a second video code stream sent by the network equipment according to the target frame skipping value.
In some embodiments, after receiving the target frame skipping value, the network device performs frame skipping processing on the first video code stream according to the target frame skipping value to obtain a second video code stream.
In some embodiments, the first video code stream may be a video code stream in a non-frame-skipping processing mode, and the second video code stream is a video code stream generated after frame skipping according to the target frame skipping value.
In some embodiments, the first video code stream may be a video code stream generated by a first video frame code stream corresponding to a data frame 1, a third video frame code stream corresponding to a data frame 3, a fifth video frame code stream corresponding to a data frame 5, and a seventh video frame code stream corresponding to a data frame 7 in sequence in a frame skipping processing mode according to a target frame skipping value 1; the second video code stream may have a target frame skipping value of 2, and the network device generates a video code stream including a first video frame code stream corresponding to the data frame 1, a fourth video frame code stream corresponding to the data frame 4, and a seventh video frame code stream corresponding to the data frame 7 in sequence.
S105: and determining target video information according to the second video code stream and the target frame skipping value.
In some embodiments, video frames are parsed from the second video stream, and compensation frame information is added between adjacent video frames according to the target frame skipping value to generate target video information.
In some embodiments, the method for determining the target video information may refer to S209 to S211 in the embodiment of fig. 2.
S106: and sending the target video information to the display screen.
The display screen can be a variable refresh rate display screen, and the display screen is used for refreshing the display screen according to the target video information so as to display the image.
Further, the display screen can smoothly display video images according to the target video information.
In some embodiments, the display screen is refreshed only according to video frames in the target video information except the compensation video frame information, and in some embodiments, the refresh rate of the display screen is variable, so that normal display of the video can be ensured.
Some embodiments of the present application provide a video information processing method including: acquiring a network occupancy rate and a video processing mode in the process of receiving a first video code stream; determining a target frame skipping value according to the network occupancy rate and the video processing mode; sending a target frame skipping value to the network equipment; receiving a second video code stream sent by the network equipment according to the target frame skipping value; determining target video information according to the second video code stream and the target frame skipping value; and sending the target video information to the display screen. In the method, the target video information is determined according to the second video code stream and the target frame skipping value, so that the display screen can smoothly display the video image according to the target video information without network channel reconstruction, and the cost is saved. Further, in the present application, when the network occupancy rate is large (i.e., the network quality is poor), the display device receives the second video stream with a default part of data frames (i.e., the amount of data frames included in the second video stream sent by the network device is reduced), so that the required amount of bandwidth by the display device is reduced.
On the basis of the above embodiments, the following describes in detail the video information processing method provided by the present application with reference to the embodiment of fig. 2, and in some embodiments, please refer to fig. 2.
Fig. 2 is a schematic flowchart of a video information processing method according to the present application. As shown in fig. 2, some embodiments of the present application provide a video information processing method including:
s201: and in the process of receiving the first video code stream, acquiring the data communication time length of the network equipment in the preset total communication time length.
S202: and determining the network occupancy rate according to the data communication time length and the total communication time length.
The preset total communication time may be 200 milliseconds, 500 milliseconds, and the like, which is not limited in this application in some embodiments.
In some embodiments, the ratio of the data communication duration divided by the total communication duration is determined as the network occupancy.
In some embodiments, network occupancy may be determined based on latency of requests.
In some embodiments, the network occupancy may be determined from the response speed.
In some embodiments, only the utilization rate capable of characterizing the capability of the network to transmit data needs to be obtained, and the specific obtaining manner may refer to the related art.
S203: and acquiring a video processing mode in the process of receiving the first video code stream.
S204: and judging whether the video processing mode is a non-frame skipping processing mode or not.
If yes, go to S205.
If not, go to S206.
S205: and if the network occupancy rate is greater than or equal to the first occupancy rate threshold value, determining the preset frame skipping value as a target frame skipping value.
In some embodiments, when the network occupancy is less than the first occupancy threshold, 0 is targeted to the frame skip value.
In some embodiments, the target frame skip value is determined according to a preset mapping relationship.
In some embodiments, the target frame skip value is determined directly from the preset mapping relationship without the occupancy threshold.
S206: if the network occupancy rate is smaller than the second occupancy rate threshold value, determining a difference value between a first frame skipping value corresponding to the frame skipping processing mode and a preset frame skipping value as a target frame skipping value; if the network occupancy rate is greater than or equal to the second occupancy rate threshold value and less than the first occupancy rate threshold value, determining the first frame skipping value as a target frame skipping value; and if the network occupancy rate is greater than or equal to the first occupancy rate threshold value, determining the sum of the first frame skipping value and a preset frame skipping value as a target frame skipping value.
Wherein the second occupancy threshold is less than the first occupancy threshold. In some embodiments, the second occupancy threshold is a ratio of the first occupancy threshold divided by N, where N may be any positive integer.
For example, when N is 2 and the first occupancy threshold is 50%, the second occupancy threshold is 25%.
For example, when the first occupancy threshold is 50%, the second occupancy threshold is 25%, the first frame skipping value is 1, and the preset frame skipping value is 1, if the network occupancy is 10%, the obtained target frame skipping value is 0(1-1 is 0), if the network occupancy is 30%, the obtained target frame skipping value is 1 (that is, equal to the first frame skipping value), and if the network occupancy is 60%, the obtained target frame skipping value is 2(1+1 is 2).
S207: and sending the target frame skipping value to the network equipment.
In some embodiments, the execution process of S207 is the same as the execution process of S103, and the execution method of S207 is not described herein again
S208: and receiving a second video code stream sent by the network equipment according to the target frame skipping value.
In some embodiments, the execution method of S208 is the same as the execution method of S104, and the execution process of S208 is not described herein again.
S209: and decoding the second video code stream to obtain a video frame to be displayed.
The video frame to be displayed comprises at least one effective video frame, and each effective video frame is obtained after one data frame in the second video code stream is decoded.
In some embodiments, each valid video frame includes a display identifier, and the display identifier is used to trigger the display screen to display a video image corresponding to the valid video frame where the display identifier is located.
In some embodiments, the valid video frames contain different display identifiers than the invalid video frames in the compensated video frames, such that the display screen determines whether the received video frames are valid video frames or invalid video frames according to the different display identifiers.
In some embodiments, the display identification is vertical synchronization data and/or horizontal synchronization data.
S210: and determining a compensation video frame according to the target frame skipping value.
The compensation video frame comprises at least one invalid video frame, and the number of the at least one invalid video frame is the same as the target frame skipping value.
In some embodiments, the amount of compensation information is determined according to the frame skipping value and the number of preset display lines, and a compensated video frame is obtained according to the amount of compensation information.
In some embodiments, the amount of compensation information is a product of the target frame skipping value and a preset number of display lines. For example, when the target frame skipping value is 2 and the number of preset display lines is 2200, the number of compensation information is 4400 lines. Further, the ineffective video information of 4400 lines is divided into 2 ineffective video frames, so as to obtain the compensated video frame.
In some embodiments, if the target frame skip value is 2 and the preset number of display lines is 2200, i.e. the number of lines per active video frame is 2200, meaning that two data frames are missing in the video bitstream, 2200 by 2 data needs to be compensated to ensure saturation of the data path between the processor and the display screen, and thus 2 frames of blank data (i.e. 2 inactive video frames) need to be compensated between two adjacent active video frames. Saturation of the data path between the processor and the display screen is required in some embodiments by the display device.
In some embodiments, if the data path between the processor and the display screens does not require saturation, the valid video frames can be directly sent to the display screens, so that the display screens perform refresh display according to the valid video frames, and the display screens can work normally because the target frame skipping value is that the frame rate of the data frames in the video code stream received by the display device conforms to the refresh rate of the display screens.

If the compensated video frames include 2 invalid video frames, the determined target video information includes: the effective video frame and the 2 ineffective video frames corresponding to the data frame 1, the effective video frame and the 2 ineffective video frames corresponding to the data frame 2. The sequence of the video frames included in the target video information sent to the display screen is as follows: the effective video frame and the 2 ineffective video frames corresponding to the data frame 1, the effective video frame and the 2 ineffective video frames corresponding to the data frame 2.
Further, after the display screen receives the target video information, the video image corresponding to the valid video frame corresponding to the data frame 1 is displayed according to the display identifier in the valid video frame corresponding to the data frame 1, and the video image corresponding to the valid video frame corresponding to the data frame 2 is displayed according to the display identifier in the valid video frame corresponding to the data frame 2, but the video image corresponding to the invalid video frame is not displayed.
