Description

Technical Field

[0001] This application relates to the field of wireless signal transmission, and in particular to a video transmission method, apparatus, electronic device, and storage medium. Background Technology

[0002] With social development, wireless network transmission technology has flourished and is being applied to an increasing number of devices. For example, wireless cameras (IPCs) on the market are primarily used in scenarios where they connect to a public cloud platform via WiFi, allowing users to access the platform via WiFi or mobile networks to view real-time video and alarm recordings of the monitored area. However, when video terminal devices connect to WiFi networks, they are affected by factors such as user installation location, wireless interference, network latency, and competition for wireless resources, resulting in weak wireless networks. This can easily lead to packet loss at the network transmission layer, causing problems such as stuttering, frame drops, latency, and desynchronization in video playback. One effective way to combat weak wireless networks is to increase wireless power and utilize it rationally for video data transmission. In related technologies, in video streaming scenarios using wireless (e.g., Wi-Fi) terminal devices, wireless power control suffers from uneven and mismatched power distribution. With weak wireless signals, this results in numerous video retransmissions, high power consumption, and low transmission efficiency, causing stuttering and frame drops in video playback. Conversely, with strong wireless signals, improper power distribution leads to high power consumption in wireless devices.

[0048] This embodiment provides a video transmission method. Figure 2 This is a flowchart of a video transmission method according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0049] Step S201: Obtain the video frame to be sent and the local transmission parameters, and determine the video parameters of the video to be sent.

[0050] In the embodiments of this application, the transmission scenario is described using a wireless WiFi device as the transmitter. When the device begins sending a video stream to the receiver, it acquires the video frame to be sent and determines the video parameters of the frame. Furthermore, the device also acquires its own transmission parameters. Additionally, the embodiments of this application can also be implemented based on other wireless technologies, such as Bluetooth or mobile cellular network technologies; this application does not impose specific limitations on these.

[0051] Step S202: Determine the number of round trip transmissions based on the video parameters and the parameters sent from the local end.

[0052] Based on the determined video parameters and the local transmission parameters, it can be determined how many round trips are expected to be required to complete the transmission of this video frame, that is, the number of round trips can be determined by calculation.

[0053] Step S203: Obtain wireless signal parameters and determine the estimated transmission time of video frames based on the number of round trips and wireless signal parameters.

[0054] Furthermore, the device obtains wireless signal parameters. The round-trip transmission count and wireless signal parameters calculated above can be used to assess the current wireless quality. Therefore, based on both, the time that this video frame may take to be sent can be estimated, i.e., the estimated transmission time of the video frame.

[0055] Step S204: Determine the video frame type of the video frame to be sent, and determine the target wireless transmission power corresponding to the video frame to be sent based on the video frame type and the estimated transmission time of the video frame.

[0056] The video frame to be transmitted can be of type I-frame or P-frame. Based on the different video frame types and the estimated transmission time of the video frame, the target wireless transmission power that simultaneously meets the requirements of video transmission efficiency and quality, as well as device power consumption, can be determined for transmitting the corresponding video frame to be transmitted.

[0057] Through the above steps, this embodiment of the application determines the video parameters of the video to be transmitted by acquiring the video frame to be transmitted and the local transmission parameters. Based on the video parameters and the local transmission parameters, it determines the number of round-trip transmissions. Simultaneously, it acquires wireless signal parameters to evaluate wireless signal quality. Based on the number of round-trip transmissions and the wireless signal parameters, it determines the estimated transmission time of the video frame and further determines the video frame type. The video frame type reflects the video frame size and service characteristics. Based on the video frame type and the estimated transmission time, it determines the target wireless transmission power corresponding to the video frame to be transmitted. Therefore, this application uses video features, service features, network features, and wireless features for multi-dimensional parameter evaluation. It adaptively controls the wireless transmission power for different video frame types and network conditions, ensuring that the wireless transmission power matches and adapts to the video transmission service. This solves the problem in related technologies of how to perceive network and video conditions in real time and adaptively adjust the wireless transmission power. It can adopt different wireless transmission powers for different video frame types, improving video transmission efficiency and playback quality while reducing device power consumption.

[0058] In some embodiments, step S202 includes:

[0059] Step S2021: Determine the amount of video frame data and fragment data included in the video parameters, as well as the congestion window size and packet loss rate included in the local transmission parameters.

[0060] In this embodiment, the video parameters include the video frame data size and the fragment data size, where the fragment data size refers to the size of a video packet formed by cutting a video frame. For example, the fragment data size corresponding to a video packet can be 1400 bytes. The local transmission parameters include the congestion window size and the packet loss rate.

[0061] Step S2022: Determine the number of round trips based on the video frame data volume, fragment data volume, congestion window size, and packet loss rate.

[0062] Specifically, based on the video frame data size, fragment data size, congestion window size, and packet loss rate, the round-trip transmission count can be calculated using the following formula:

[0063] Round trip transmission count = video frame data volume / fragment data volume / congestion window size + (video frame data volume / fragment data volume × packet loss rate) / congestion window size.

[0064] Through the above steps, this application embodiment provides a specific method for calculating the number of round-trip transmissions based on the video frame data volume, fragment data volume, congestion window size, and packet loss rate, which is highly feasible.

[0065] In some embodiments, step S203 includes:

[0066] Step S2031: Determine the wireless data round-trip delay and wireless packet loss rate included in the wireless signal parameters.

[0067] Step S2032: Determine the estimated transmission time of the video frame based on the number of round-trip transmissions, the wireless data round-trip delay, and the wireless packet loss rate.

[0068] In this embodiment, the wireless signal parameters include wireless data round-trip delay and wireless packet loss rate. Based on the number of round-trip transmissions, wireless data round-trip delay, and wireless packet loss rate, the estimated transmission time of video frames can be calculated using the following formula:

[0069] Estimated transmission time for video frames = (Number of round trips + (Video frame data size / Fragment data size × Wireless packet loss rate) / Congestion window size) × Wireless data round trip delay.

[0070] Through the above steps, this application embodiment provides a specific and accurate method for calculating the estimated transmission time of video frames based on the number of round-trip transmissions, wireless data round-trip delay, congestion window size, and wireless packet loss rate.

[0071] In some embodiments, step S204 includes:

[0072] Step S2041: Determine the video frame type and power configuration rules for the video frame to be sent.

[0073] Step S2042: Determine the target wireless transmission power corresponding to the video frame to be transmitted based on the video frame type, power configuration rules, and estimated transmission time of the video frame.

[0074] In this embodiment, the power configuration rules can be determined based on a preset power configuration table. This table records the corresponding wireless transmission power determined based on parameters such as video frame type and estimated transmission time. Therefore, the target wireless transmission power for transmitting the video frame to be sent is determined according to the video frame type, power configuration rules, and estimated transmission time.

[0075] Through the above steps, this embodiment of the application determines the power configuration rules through a power configuration table, and further determines the target wireless transmission power corresponding to the video frame to be transmitted based on the video frame type, power configuration rules and estimated transmission time of the video frame, thereby improving the configuration efficiency of wireless transmission power.

[0076] In some embodiments, step S2042 includes:

[0077] Step S2142: When the video frame type is the first I-frame and the estimated transmission time of the video frame is greater than the first preset threshold, the first target wireless transmission power corresponding to the video frame to be transmitted is determined according to the power configuration rule.

[0078] In this embodiment, if the data to be sent is the first video I-frame of the stream, i.e., the video frame type of the video to be sent is the first I-frame, and the estimated transmission time of the video frame exceeds the first preset threshold α, then the transmission of the first I-frame needs to be accelerated. The device increases the current power configuration by k1×δdBm according to the power configuration table commonly used in the industry as stipulated by law, in order to determine the first target wireless transmission power corresponding to the video frame to be sent. The first preset threshold α can be set according to business requirements. For example, when the business requires the transmission to be completed within 40ms, it is set to 40ms. This setting is suitable for scenarios where users need to quickly display the video and improve the streaming speed. In the case of large WiFi signal interference or weak signal, the power can be instantly increased to speed up the transmission of the video I-frame. k1 is (WT1-α) / α, where WT1 is the estimated transmission time of the video frame; δ is the wireless transmission power value for the I-frame before adjusting the power configuration.

[0079] Through the above steps, this application embodiment, when the video frame type of the video to be sent is the first I-frame, specifically increases the wireless transmission power under weak wireless signal conditions, accelerates the transmission of the first video I-frame, reduces the problem of user video playback stuttering and frame dropping caused by wireless link packet loss, improves the outgoing speed of the first I-frame, and ensures video transmission efficiency and quality.

[0080] In some embodiments, step S2042 includes:

[0081] Step S2242: Obtain channel utilization and signal strength.

[0082] Step S2342: When the video frame type is not the first I-frame, and the estimated transmission time of the video frame is greater than the second preset threshold, the channel utilization is greater than the utilization threshold, and the signal strength is less than the strength threshold, the second target wireless transmission power corresponding to the video frame to be transmitted is determined according to the power configuration rules.

[0083] In this embodiment of the application, channel utilization and signal strength are further obtained. If the data to be transmitted is a non-first video I-frame, that is, the video frame type of the video frame to be transmitted is a non-first I-frame, and the estimated transmission time WT1 of the video frame exceeds the second preset threshold β, and the channel utilization exceeds the preset utilization threshold, and the signal strength is lower than the preset strength threshold, then the transmission of the non-first I-frame needs to be accelerated. The device increases the current power configuration by k2×δdBm according to the power configuration table to determine the second target wireless transmission power corresponding to the video frame to be transmitted, where k2 is (WT1-β) / β, WT1 is the estimated transmission time of the video frame, and δ is the wireless transmission power value for the I-frame before adjusting the power configuration. Specifically, during video playback, if the user only cares about smoothness, as long as the video is sent within a preset threshold (e.g., 200ms), the user will not experience any stuttering or other poor viewing experience. However, in scenarios where wireless transmission efficiency is low due to strong wireless interference, the transmission of non-first I-frames slows down, resulting in a poorer viewing experience for the user. In this case, the aforementioned power configuration enhancement scheme can allow WiFi to instantly increase its power, thereby accelerating the transmission of non-first I-frames.

[0084] Through the above steps, this application embodiment further obtains channel utilization and signal strength to evaluate wireless signal quality when the video frame type of the video to be sent is not the first I-frame. In the case of weak wireless signal, it increases wireless transmission power, accelerates the transmission of non-first video I-frames, reduces the problem of user video playback stuttering and frame dropping caused by wireless link packet loss, and improves video transmission efficiency and quality.

[0085] In some embodiments, step S2042 includes:

[0086] Step S2442: Obtain the device power mode. Under the conditions that the video frame type is P frame, the estimated transmission time of the video frame is less than the third preset threshold, the device power mode is low power mode, the channel utilization is less than the utilization threshold, and the signal strength is greater than the strength threshold, determine the third target wireless transmission power corresponding to the video frame to be transmitted according to the power configuration rules.

[0087] In this embodiment, the device power mode is further obtained. If the data to be transmitted is a streaming video P-frame, that is, the video frame type of the video frame to be transmitted is P-frame, and the device power mode is low power mode, and the estimated transmission time of the video frame is lower than the third preset threshold φ, and the channel utilization is lower than the preset utilization threshold, and the signal strength is higher than the preset strength threshold, then the transmission speed of the P-frame can be reduced. The device reduces the current power configuration by h×εdBm according to the power configuration table to determine the third target wireless transmission power corresponding to the video frame to be transmitted, where h is (φ-WT1) / φ, WT1 is the estimated transmission time of the video frame, and ε is the wireless transmission power value for the P-frame before adjusting the power configuration. Specifically, during video playback, if the user only cares about smoothness, as long as the video is sent within a preset threshold (e.g., 200ms), the user will not experience any stuttering or other poor viewing experience. Therefore, in scenarios with low wireless interference and high signal quality, wireless transmission efficiency is high. Even if the wireless power is momentarily reduced to transmit P-frames slowly, it will not affect business needs (the video can still be sent within the preset threshold). At the same time, it can reduce device power consumption and extend the battery life of products such as battery-powered cameras.

[0088] Through the above steps, in this embodiment of the application, when the video frame type of the video frame to be sent is a P-frame, the wireless transmission power during P-frame transmission is reduced when the wireless signal is strong, thereby saving the problem of large power consumption loss caused by the waste of wireless device transmission power and reducing device power consumption loss.

[0089] As can be seen, the embodiments of this application perform multi-dimensional parameter estimation based on video features, service features, network features, and wireless features, and dynamically adjust the wireless transmission power for different video frame types. This achieves accelerated transmission of video I-frames and energy-saving transmission of video P-frames under a wireless network, thereby ensuring that the wireless transmission power is perfectly matched and adapted to the peak-valley characteristics and service status of different types of video frame sizes. This improves video transmission efficiency and reduces device power consumption. Furthermore, in the embodiments of this application, once video frame transmission is complete, the device restores the wireless transmission power to its previous configuration.

[0090] The embodiments of this application will be described and illustrated below through preferred embodiments.

[0091] Figure 3 This is a flowchart of a video transmission method according to a preferred embodiment of this application. Figure 3 As shown, the video transmission method includes the following steps:

[0092] Step S301: Obtain the video frame to be sent and the local transmission parameters, and determine the video parameters of the video to be sent.

[0093] Step S302: Determine the amount of video frame data and fragment data included in the video parameters, as well as the congestion window size and packet loss rate included in the local transmission parameters.

[0094] Step S303: Determine the number of round trips based on the video frame data volume, fragment data volume, congestion window size, and packet loss rate.

[0095] Step S304: Determine the wireless data round-trip delay and wireless packet loss rate included in the wireless signal parameters.

[0096] Step S305: Determine the estimated transmission time of the video frame based on the number of round-trip transmissions, the wireless data round-trip delay, and the wireless packet loss rate.

[0097] Step S306: Determine the video frame type of the video frame to be sent, and determine the target wireless transmission power corresponding to the video frame to be sent based on the video frame type and the estimated transmission time of the video frame.

[0098] Furthermore, when the transmitting end includes a wireless power control transmission module and a wireless driving module, this application can also have the following implementation methods. First, the transmitting end segments the video frame into video packets of different sizes according to a certain size, and the video packets are transmitted to the receiving end via the wireless power control transmission module and the wireless driving module. Second, the wireless driving module senses changes in the wireless signal status in real time and sends the signal parameters to the wireless power control transmission module for evaluation. Third, after receiving the video packets, the receiving end also sends reception information and evaluates the packet loss and acknowledgment status of the receiving end. This information is fed back to the transmitting end through an acknowledgment character message. Fourth, the wireless power control transmission module of the transmitting end performs a comprehensive evaluation based on the acknowledgment character feedback information, wireless signal feedback information, and the transmitting end's video frame information, and calculates the wireless transmission power of the device in the next video frame transmission time slot in real time. Finally, the wireless power control transmission module sends a power configuration to the wireless driving module to adaptively adjust the wireless transmission power, thereby improving the video frame transmission's ability to resist weak signals, especially the enhancement capability of video I-frame transmission signals.
