Simulated Video Streaming via Audio-Synchronized Image Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video conferencing systems face limitations due to bandwidth constraints and costs associated with real-time video streaming, which can hinder the availability and quality of video communication, especially in scenarios where intrusive video generation is undesirable.
Innovation Solution
The method and system utilize image sequences synchronized with voice information to simulate video streaming, where image sequences are generated dynamically, pre-generated, or retrieved from an external source, and encoded into voice streams, allowing for simulated video streaming that reduces bandwidth requirements and can be used in place of actual video streams during communication sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time video streaming is used during video conferencing, then video communication quality is improved, but bandwidth consumption increases
Solution Approach 1:
The patent creates a simulated video stream by generating image sequences that copy the essential visual characteristics of real video (mouth movements, facial expressions) without transmitting actual video data. This allows the receiving device to reconstruct video content from audio data alone, significantly reducing bandwidth consumption while maintaining adequate communication quality
Solution Approach 2:
The patent extracts only the most critical visual elements (mouth position, facial movements) from complete video streams and represents them through image sequences synchronized with audio. By taking out only the essential visual information needed for communication rather than transmitting full video, bandwidth requirements are reduced while preserving communication effectiveness
2Reliability
If real-time video streaming is used during video conferencing, then video communication availability is improved, but costs increase
Solution Approach 1:
By generating simulated video streams locally at the receiving device using audio-driven image sequences, the system eliminates or reduces the need to transmit expensive real-time video data over the network, thereby reducing communication costs while maintaining video availability
Solution Approach 2:
The receiving device performs self-service by generating its own video stream representation from received audio data and stored image sequences, rather than relying on the transmitting device to provide actual video. This shifts the processing burden to the receiving end and reduces network resource consumption
Data Source
AI summary
A communication device is operable to construct one or more image sequences that correspond to voice information, where the image sequences simulate video streaming via the communication device. The image sequences are synchronized with the voice information during active video based connection via the communication device. The image sequences are generated and/or retrieved within the communication device, and/or retrieved from an external source. At least some of the images may be generated via a secondary device that is communicatively coupled with the communication device. The generated images are stored within the secondary device and/or are stored in a dedicated video support server. The secondary device is operable to communicate the images directly during communication with the communication device and/or to communication information that enable retrieving and/or constructing the image sequences. Alternatively, the communication device is operable to generate the image sequences independently.
