Foundation Model Empowered Real-Time Video Conference With Semantic Communications
Summary
This study introduces a novel framework for real-time video conferences using foundation models. It significantly enhances interactivity and achieves high compression ratios with excellent semantic fidelity in video transmission.
Area of Science:
- Computer Vision for Communications
- Multimedia Services
- Artificial Intelligence Foundation Models
Background:
- Real-time video conferences generate substantial traffic due to proliferating interactive multimedia services.
- Existing Computer Vision (CV) techniques lack integration for diverse interactive video tasks like recognition and segmentation.
- The rise of foundation models presents opportunities for task-oriented semantic communications.
Purpose of the Study:
- To propose a novel framework, Real-Time Video Conference with Foundation Model (RTVCFM), for enhanced interactivity in multimedia services.
- To address the limitations of current CV methods in handling complex interactive video demands.
- To leverage foundation models for efficient and high-fidelity video transmission.
Main Methods:
- At the transmitter: Causal understanding and spatiotemporal decoupling using Video Time-Aware Large Language Model (VTimeLLM), Iterated Integrated Attributions (IIA), and Segment Anything Model 2 (SAM2) for semantic segmentation.
- During transmission: Two-stage semantic transmission optimization driven by Channel State Information (CSI) for low bit rate and high semantic fidelity.
- At the receiver: Multidimensional fusion using Diffusion Model for Foreground Background Fusion (DMFBF) for video stream reconstruction.
Main Results:
- Achieved a compression ratio as high as 95.6%.
- Guaranteed high semantic similarity with 98.73% in Multi-Scale Structural Similarity Index Measure (MS-SSIM) and 98.35% in Structural Similarity (SSIM).
- Demonstrated that reconstructed videos are highly similar to original videos.
Conclusions:
- RTVCFM effectively satisfies the interactivity requirements of real-time multimedia services.
- The proposed framework enables significant video compression while preserving high semantic fidelity.
- This approach showcases the potential of foundation models in advancing computer vision for communications.

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.
