Key research themes

1. How can video streaming protocols optimize bandwidth and latency for scalable game streaming?

This research area investigates novel broadcasting and streaming protocols designed to enhance the efficiency of game video delivery, focusing on reducing bandwidth usage while minimizing start-up and waiting times. It matters because the scalability and quality of game streaming services critically depend on the optimization of network resources and latency management. Efficient protocols enable simultaneous servicing of multiple viewers with low buffering delays, thus improving overall Quality of Experience (QoE) for games with varying demand profiles.

Key finding: Introduced the Pagoda broadcasting protocol, which hybridizes harmonic and non-harmonic broadcasting to utilize a small number of data streams with almost the minimal bandwidth required to guarantee a specific maximum waiting... Read more
Key finding: Proposed the use of partial preloading of initial video segments on client devices to eliminate extra bandwidth requirements and achieve instantaneous access to popular videos. Two new protocols, PHB-PP and Mayan Temple... Read more
Key finding: Presented the Patching multicast scheme that dynamically expands existing multicast streams to serve new clients, eliminating service latency and improving multicast efficiency. Simulation results show substantial... Read more
Key finding: Developed HTTP/2-based push mechanisms to reduce start-up delay and camera-to-display latency by over 40% and 90% respectively in live adaptive streaming. By enabling super-short segments to be pushed immediately, it offers a... Read more

2. How is adaptive streaming being enhanced to address latency and quality trade-offs in mobile and live game streaming?

This theme focuses on adaptive bitrate algorithms and streaming methodologies tailored for the constraints of live and mobile streaming environments. It is essential because game streaming demands low latency and high video quality despite fluctuating network conditions, especially on wireless or mobile devices. Enhancements in adaptive streaming algorithms directly impact smooth gameplay and visual experience.

Key finding: Proposed the Llama ABR algorithm optimized for low latency HTTP Adaptive Streaming (HAS) with small client buffers, enabling faster response to bandwidth variation while reducing latency to 30-90 seconds. This approach... Read more
Key finding: Implemented a Reinforcement Learning (RL) based adaptive bitrate streaming client on Android, integrating network-aware reward functions to optimize video quality and prebuffering. Experiments in real wireless testbeds... Read more
Key finding: Conducted a comparative study of congestion control and adaptation protocols (VTP, TFRC Wireless, MULTFRC) for real-time streaming over wireless links, highlighting the challenges of random packet loss and high error rates.... Read more
Key finding: Introduced ADWS, an aggressive and dynamic window-sliding method for online smoothing of variable bit rate (VBR) streams, dynamically optimizing transmission schedules to lower peak bandwidth demands. This technique ensures... Read more

3. What are the social, economic, and industry implications of live game streaming for the video game ecosystem?

This theme explores how live game streaming platforms like Twitch and cloud gaming services are reshaping the video game industry, affecting game marketing, user engagement, and business models. Understanding these socio-economic effects is crucial for researchers analyzing the evolving interplay between streaming technology, content creators, players, and commercial stakeholders in gaming.

Key finding: Through extensive ethnographic research and interviews with live streamers, the paper showed that Twitch streaming has fundamentally influenced game marketing, visibility of niche games, and game development processes. It... Read more
Key finding: Affirmed and expanded the findings on Twitch's role in the modern games industry by documenting how streaming informs consumer choice, offers exposure to independent titles, and revolutionizes game creation visibility. Based... Read more
Key finding: Analyzed the technical advances and economic transformations induced by cloud gaming, emphasizing shifts from ownership to subscription models and the resulting challenges such as latency and player loyalty. Provides... Read more
Key finding: Identified the critical yet overlooked off-camera labor in game live streaming, including community building, content planning, and networking, that sustains professional streamers’ careers. Interview data revealed how this... Read more
Key finding: Demonstrated that microstreamers’ unstaged, shared physical environments foster deep audience intimacy and authenticity, differentiating smaller scale streaming from professional broadcasted streams. Explores the interplay... Read more
