ADAPTIVE PLAYBACK METHOD AND DEVICE FOR VIDEO - A simplified explanation of the abstract
This abstract first appeared for US patent application 18263683 titled 'ADAPTIVE PLAYBACK METHOD AND DEVICE FOR VIDEO
Simplified Explanation
The present disclosure describes an adaptive playback method and device for video, where the playback instruction for a target video is received and the video is played according to a first code rate determined by predicting network speed and using a code rate prediction model.
- Predict network speed using a network speed prediction algorithm.
- Acquire a code rate prediction model corresponding to the network speed prediction algorithm.
- Determine the first code rate corresponding to the first network speed through the code rate prediction model.
Potential Applications
This technology could be applied in video streaming services, online gaming platforms, and other multimedia applications where adaptive playback based on network speed is crucial.
Problems Solved
This technology solves the problem of buffering and lag in video playback by dynamically adjusting the code rate based on predicted network speed, ensuring smooth and uninterrupted viewing experience.
Benefits
The benefits of this technology include improved user experience, optimized video playback quality, and efficient use of network resources by adapting to varying network conditions in real-time.
Potential Commercial Applications
Potential commercial applications of this technology include video streaming platforms, online education services, and video conferencing tools that can benefit from adaptive playback based on network speed.
Possible Prior Art
One possible prior art could be adaptive bitrate streaming technologies used in video streaming services to adjust video quality based on network conditions. Another could be network speed prediction algorithms used in network optimization tools to predict network performance.
Unanswered Questions
How does the code rate prediction model handle sudden fluctuations in network speed?
The code rate prediction model may need to be robust enough to adapt to sudden changes in network speed to ensure optimal video playback quality.
What impact does this technology have on data usage for users with limited data plans?
It would be important to consider how adaptive playback based on network speed affects data usage for users with limited data plans, as higher code rates may consume more data.
Original Abstract Submitted
Embodiments of the present disclosure provide an adaptive playback method and device for video, the method includes: receiving a playback instruction for a target video; and playing the target video according to a first code rate in response to the playback instruction; where the first code rate is determined by the following steps: predicting by using a network speed prediction algorithm to obtain a first network speed; acquiring a code rate prediction model corresponding to the network speed prediction algorithm, where the code rate prediction model is used for representing, under a historical performance parameter before switching to the network speed prediction algorithm, a mapping relationship between a network speed predicted by the network speed prediction algorithm and a code rate; and determining the first code rate corresponding to the first network speed through the code rate prediction model.
