SpaAbr: Size Prediction Assisted Adaptive Bitrate Algorithm for Scalable Video Coding Contents

Dynamic Adaptive Streaming over HTTP(DASH) is a video transmission ptotocol to adapt to different network conditions and heterogeneous client devices. The client first requests and parses the Media Presentation Description(MPD) file from the DASH …

An Elastic System Architecture for Edge Based Low Latency Interactive Video Applications

5G and edge computing have brought great changes to video industry. Interactive video is becoming an emerging application form of multimedia service, which provides attraction beyond typical scenarios like cloud gaming and remote virtual reality …

Deep Blind Video Quality Assessment for User Generated Videos

As short video industry grows up, quality assessment of user generated videos has become a hot issue. Existing no reference video quality assessment methods are not suitable for this type of application scenario since they are aimed at synthetic …

Quality of Experience Evaluation for Streaming Video Using CGNN

One of the principal contradictions these days in the field of video i s lying between the booming demand for evaluating the streaming video quality and the low precision of the Quality of Experience prediction results. In this paper, we propose …

TSGAN: A Two-Stream Generative Adversarial Network for Bit-Depth Expansion

The rapid development of display devices and the continuous improvement of visual quality requirements put urgent demands on high bit-depth (HBD) image, but most legacy data are stored and transmitted at low bit-depth (LBD). Bit-depth expansion (BDE) …

FPGA Based Video Transcoding System with 2K-4K Super-Resolution Conversion

We present a FPGA-based system supporting video stream transcoding with 2k full high-definition (FHD) video to 4k ultra high-definition (UHD) video super- resolution(SR) conversion. Our system focuses on building a functional pipeline with …

Guest Editorial Special Issue on Quality of Experience for Advanced Broadcast Services

During the last decade, the evolution of the TV market has been remarkable. Broadcasters have been facing fresh challenges to cope with an increasing user demand for new services. With second-screen adoption and the increase of real-time news …

Two-stream deep encoder-decoder architecture for fully automatic video object segmentation

We propose a two-stream Deep Encoder-Decoder architecture to tackle the task of fully automatic video object segmentation. Both two streams, i.e., ImSeg-Stream (for static image segmentation) and MoSeg-Stream (for optical flow segmentation), hold the …

The SJTU UHD 360-Degree Immersive Video Sequence Dataset

This paper presents a set of 12 new 8K resolution ultra-high definition (UHD) 360-degree immersive video sequences. This video sequences can satisfy the enhancing requirements of the researches on UHD 360-degree immersive video, such as …

View-Dependent Omnidirectional Video Encapsulation Using Multiple Tracks

In recent years, there has been a significant interest towards virtual reality applications, especially omnidirectional videos. Due to the huge resolutions, omnidirectional videos are difficult to codec and stream in term of traditional multimedia …
