Key research themes

1. How can broadcasting protocols optimize bandwidth and reduce latency for live streaming in video on demand (VoD) services?

This research area investigates the design and evaluation of broadcasting protocols that improve the efficiency of delivering video on demand services, focusing on minimizing bandwidth consumption while ensuring low maximum waiting times and latency for viewers. It is critical because VoD systems must scale to many simultaneous viewers without excessive bandwidth use and must offer high-quality, low-latency viewing experiences to compete with traditional broadcast and video rental services.

Key finding: Introduced the pagoda broadcasting protocol, a hybrid approach combining the high efficiency of harmonic broadcasting with the manageability of non-harmonic protocols, using fewer high-bandwidth streams while requiring only... Read more
Key finding: Presented two variants of harmonic broadcasting—cautious harmonic broadcasting and quasi-harmonic broadcasting—that guarantee on-time delivery of all video frames without increasing user waiting times, achieving lower... Read more
Key finding: Developed a forward unilateral prediction model in the SNP/VQR codec enabling scalable video streaming with dynamic bandwidth adaptation and robust error concealment in wireless environments, resulting in relatively constant... Read more

2. What strategies enhance low latency and quality of experience (QoE) for adaptive live streaming over HTTP and mobile networks?

This theme addresses optimizing HTTP Adaptive Streaming (HAS) technologies and adaptive bitrate (ABR) algorithms to minimize end-to-end latency, reduce buffering events, and improve video quality, especially for live content. It also investigates mobile-friendly adaptive streaming implementations, including reinforcement learning approaches and emerging protocols like HTTP/2 to improve interactivity and reduce start-up delays.

Key finding: Proposed Llama, a low-latency adaptive bitrate (ABR) algorithm designed for HTTP Adaptive Streaming with small client buffers, which reacts rapidly to network changes to reduce playback latency and rebuffering events, showing... Read more
Key finding: Introduced a push-based HTTP/2 live streaming method that pushes super-short segments immediately upon availability, achieving a 90.1% reduction in server-to-display delay and 40.1% reduction in start-up delay compared to... Read more
Key finding: Developed and experimentally validated a reinforcement learning-based adaptive streaming client for Android using MPEG-DASH, improving quality of experience by dynamically adapting bitrate to wireless network conditions,... Read more

3. How do social and interactional dynamics influence user engagement and monetization behaviors in live streaming apps?

This research area examines the user motivations, social relationships, and engagement patterns underlying virtual gift donations and participation in live streaming platforms. It explores parasocial relationships between viewers and streamers, social presence among viewers, and community dynamics, which affect both the experience quality and the economic models of live streaming ecosystems.

Key finding: Demonstrated that viewer motivations to purchase virtual gifts for streamers are positively influenced by parasocial relationships, enjoyment, loyalty, and trust, and that social presence among viewers moderates these... Read more
Key finding: Proposed the SCORE system that combines broadcast push and online pull methods by predicting user viewing patterns and pre-recording content on local devices, thereby reducing network load and energy consumption while... Read more
Key finding: Identified and analyzed the extensive off-camera labor of professional and semi-professional live streamers, including community building, content planning, and self-presentation, revealing the high social and psychological... Read more
