Events

Demuxed, 24-25 Oct, USA

Demuxed is a conference and community founded in 2015 by video engineers, catering to the technical side of video technology. It offers a platform for engineers involved in encoding, delivery, playback, and related areas. This year we also participated - Alvaro Laserna Lopez, Director of R&D and Test Automation and Country Manager at TestDevLab, attended and discussed the challenge of finding reliable metrics for audio quality assessment, noting limitations in existing algorithms like POLQA and ViSQOL.

To address this, we have developed two new deep learning-based algorithms: SpeechQ for speech transcription and ASQ-ViT for audio classification using spectrogram transformers. The results showed a strong correlation with subjective scoring, demonstrating the effectiveness and simplicity of these algorithms in providing objective quality measurements for audio outputs.

Some topics included:

Kyber, A New Approach for Real-Time Video and Controls Streaming Based on QUIC: Kyber is an innovative open-source project introducing a real-time video and controls streaming approach based on the Quic protocol. Offering low-latency encoding and decoding, it supports many applications such as Remote Desktop, Cloud Gaming, and Drone/Robot control, providing cross-platform compatibility for both client and server side, achieving impressive 20/25ms glass-to-glass latency using codecs like H.264, HEVC, VP9, and AV1, and leveraging FFmpeg and VLC for implementation.

VIDEO @Scale, 29-30 Nov

Video @Scale 2023 is a technical conference for engineers who develop or manage large-scale video systems.

This year there was an in-person meeting hosted by Sony Interactive Entertainment (SIE) at their headquarters in San Mateo, CA, USA from June 26-30. There was also an online meeting hosted by the University of Konstanz from Dec 18-21. Some of the topics discussed included:

Comparison of Conditions for Omnidirectional Video with Spatial Audio in Terms of Subjective Quality and Impacts on Objective Metrics Resolving Power: This discussion revolved around audiovisual quality metrics for video streaming services, particularly models like VMAF_ViSQOL and P1203. The study evaluated the performance of these metrics, emphasizing resolving power and efficiency in assessing 360° videos with high-order ambisonics (HOA) audio across different setups. The conclusion suggested exploring the relationship between metrics' discriminability and resolving power, proposing new parameter-based models, and outlining future work analyzing additional data, including video-only scores and audio impacts across setups.
QoE for Remote Control and Human Interaction in Industrial Tele-Operated Driving: Kjell Brunnström from RISE Research Institutes of Sweden presented RISE's mission to support small and medium enterprises. His focus was on Quality of Experience (QoE) for remote control scenarios, including measurements of perceived sound and eye movement. He also touched on human interaction in industrial tele-operated driving and perceptual aspects of real-time video streaming with drones.
