A Real-Time Video Quality Metric for HTTP Adaptive Streaming

ICASSP 2024accepted

In HTTP Adaptive Streaming (HAS), a video is encoded at multiple bitrate-resolution pairs, referred to as representations, which enables users to choose the most suitable representation based on their network connection. To optimize the set of bitrate-resolution pairs and improve the Quality of Expe…

Energy-Aware Resolution Selection for Per-Title Encoding

ICASSP 2024accepted

With the ubiquity of video streaming, optimizing the delivery of video content while reducing energy consumption has become increasingly critical. Traditional adaptive streaming relies on a fixed set of bitrate-resolution pairs, known as bitrate ladders, for encoding. However, this "one-size-fits-al…

OPTE: Online Per-Title Encoding for Live Video Streaming

ICASSP 2022accepted

Current per-title encoding schemes encode the same video content at various bitrates and spatial resolutions to find an optimized bitrate ladder for each video content in Video on Demand (VoD) applications. However, in live streaming applications, a bitrate ladder with fixed bitrate-resolution pairs…
