Key research themes

1. How can video-on-demand broadcasting protocols optimize bandwidth and waiting time with client-side storage constraints?

This research area focuses on designing bandwidth-efficient broadcasting protocols for Video-on-Demand (VoD) systems that minimize client waiting time while respecting limitations in set-top box (STB) storage. Achieving a low maximum waiting time is critical for user experience, but it must be balanced with server bandwidth and implementation complexity. The protocols leverage client buffering and preloading strategies to enhance service efficiency, enabling simultaneous servicing of many users watching popular videos without dedicating a separate stream per user.

Key finding: Introduced the pagoda broadcasting protocol combining harmonic broadcasting's fine-grained low-bandwidth streams with pyramid broadcasting's fewer streams of higher bandwidth. This hybrid method requires only slightly more... Read more
Key finding: Proposed two novel protocols that use partial preloading of the first few minutes of top videos in the STB storage to eliminate user waiting time completely. The Polyharmonic Broadcasting with Partial Preloading (PHB-PP)... Read more

2. What multicast and stream-sharing techniques enable scalable, true video-on-demand services with minimal client latency?

This theme explores multicast-based approaches that allow multiple clients to share video streams dynamically, improving bandwidth utilization and reducing server load. It emphasizes reactive or true VoD systems that provide immediate service without batching delays and explores adaptive streaming mechanisms enabling clients to tap into existing streams. These methods enhance scalability and reduce startup latency compared to traditional dedicated streaming approaches.

Key finding: Presented the stream tapping technique that enables clients to tap into existing server streams carrying useful data segments. This reactive system reduces server bandwidth usage to less than 20% of that needed by... Read more
Key finding: Introduced the Patching multicast method wherein an existing multicast stream dynamically expands to serve new clients instantly without batching delays. This enables true VoD with zero service latency by allowing clients to... Read more

3. How does adaptive bitrate streaming improve low-latency live video delivery and user Quality of Experience (QoE)?

This line of research investigates HTTP Adaptive Streaming (HAS) mechanisms for live video delivery that minimize end-to-end latency while maintaining smooth playout. It explores the tradeoffs between client buffering, bitrate adaptation speed, and playback interruptions. Designing fast-reacting yet stable Adaptive Bitrate (ABR) algorithms operational at very small client buffers is critical to reduce startup and peer latency and maintain high video quality with minimal stalling.

Key finding: Evaluated the Llama ABR algorithm designed for HAS live streaming with small client buffers targeting latencies under 10 seconds. Llama achieves quicker adaptation to fluctuating network throughput, substantially reducing... Read more
