HLS
A streaming protocol introduced by Apple that segments a video stream into small TS chunks delivered over HTTP. It offers broad compatibility and is currently the dominant live-streaming distribution protocol, with M3U8 serving as its core carrier format.
Timeline (last 90 days)
Traditional HLS latency typically ranges from 6 to 30 seconds.
Adaptive Bitrate Streaming (ABR) pre-encodes the same video into multiple resolution and bitrate versions, with the player switching in real time based on network bandwidth; HLS and DASH are the two most mainstream ABR protocols.
The research team designed and compared four workflows: direct RTL design, agent-based HLS design, post-compilation HLS refinement, and post-HLS RTL refinement.
The paper's core contribution, AHRR (Agent-based HLS with RTL Refinement), combines agent-based HLS design with post-HLS RTL refinement, forming a workflow that first constructs the design at a high level of abstraction and then returns to the RTL layer to reclaim low-level optimization opportunities.
By introducing High-Level Synthesis (HLS) as the agent's working level combined with RTL-level refinement, the research team achieved an average geometric mean speedup of 2.6× over direct RTL design on multi-task benchmarks.
HLS can distill design knowledge into abstract structures that agents can effectively leverage, reducing the cognitive burden on the agent.
The value of post-HLS RTL refinement lies in its ability to re-exploit optimization opportunities that can only be realized at the lower level.
HLS allows designers to describe hardware behavioral logic in high-level languages such as C, C++, or SystemC, with the corresponding RTL implementation automatically inferred by synthesis tools.
The Earth observation foundation model previously released by NASA and IBM is based on the Prithvi architecture and was trained using time-series satellite imagery from the Harmonized Landsat and Sentinel-2 (HLS) dataset.
Modern video platforms widely adopt two adaptive streaming protocols, DASH and HLS; DASH uses MPD manifest files and HLS uses M3U8 manifest files.
