What is it about?
The focus of this article is to introduce a new mobile video streaming system called BiSR, which aims to reduce bandwidth consumption while improving perceived video quality. To achieve this goal, our work utilizes a new video codec, which improves video quality through keyframe downsampling and super-resolution. Additionally, we have modified the structure of the DNN to accelerate the inference time of the SR process. Finally, we apply the proposed BiSR to a reinforcement learning-based adaptive bitrate streaming mechanism and design a performance evaluation based on real network tracking. Through comparison with NEMO and traditional H.264 video codecs, we demonstrate the superiority of BiSR, which can achieve better results in video quality and data rate, thereby improving the quality experience for users.

Why is it important?
Our research shows that integrating multiple modules can provide a better video experience for mobile devices, even with limited computing power.
Perspectives
I hope this article can provide assistance to researchers in the field of video streaming transmission, making the most of mobile computing power to improve video transmission quality.
