D2D Video Data Separation for Synchronized Multi-Device Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face challenges in efficiently transmitting and receiving video data due to the complexity of separating and synchronizing video data and related data, such as audio or text, across device-to-device (D2D) communication networks, particularly in ultra-high frequency bands and diverse communication environments.
Innovation Solution
A method and apparatus for D2D communication systems that separate video data from video container data and transmit video-related data to receiving devices, using techniques like broadcasting, grouping, and unicast, ensuring synchronization with video data output, and managing radio resources through nodes and servers to maintain data integrity and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video container data is transmitted as a single unit in D2D communication, then data transmission is simple, but video data and video-related data cannot be separated for synchronized output across multiple devices
Solution Approach 1:
The patent segments video container data into separate video data and video-related data components during transmission. This allows receiving devices to process and output video and audio (or other related data) independently, enabling synchronized multi-device output while maintaining the ability to separate data types for efficient handling
2Reliability
If video data and video-related data are transmitted together to all receiving devices, then data integrity is maintained, but transmission efficiency and resource utilization decrease
Solution Approach 1:
The patent applies local quality by allowing different receiving devices to receive different types of data based on their specific capabilities and roles. For example, display devices receive video data while audio devices receive video-related data, optimizing resource utilization and transmission efficiency while maintaining data integrity for each device type
3Productivity
If video container data is separated into video data and video-related data during transmission, then synchronized output across multiple devices is enabled, but transmission complexity increases
Solution Approach 1:
The patent performs preliminary action by separating video data and video-related data during the transmission phase rather than at the receiving end. This upfront segmentation simplifies the processing burden on receiving devices while enabling synchronized output across multiple device types with different capabilities
Data Source
AI summary
A method and apparatus for transmitting and receiving data in a communication system are disclosed and relate to 5th generation (5G) or pre-5G communication system that will be provided to support a higher data transmission rate after the 4G communication system, such as long term evolution (LTE). A method for transmitting data by a transmitting device in a wireless communication system that supports device-to-device (D2D) communication, may include separating, from a piece of video container data, video data and video-related data that is output together with the video data, outputting the video data, and transmitting the video-related data to a receiving device.
