Selective Video Packet Encryption for Lower Transmission Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission encryption methods encrypt large data granules, including non-essential data, leading to increased system power consumption.
Innovation Solution
Implement fine-grained control by encrypting data packets based on video data lines and auxiliary data packets, using encryption identifiers to differentiate between types of data for selective encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption protection is performed on all transmitted video data using conventional technologies, then data security is improved, but system power consumption increases due to encrypting non-essential data
Solution Approach 1:
The patent segments video data into different types (image frame data and auxiliary data) and applies encryption selectively based on the data type. Image frame data is encrypted while auxiliary data is transmitted without encryption, thereby reducing power consumption while maintaining security for critical content.
Solution Approach 2:
The patent applies different encryption treatments to different parts of the video data stream based on their importance. Critical image frame data receives encryption protection while less critical auxiliary data is transmitted in plain text, optimizing the balance between security and power consumption.
2Productivity
If encryption granularity is large (encrypting entire video frames or large data blocks), then encryption processing speed is improved, but unnecessary data including non-essential information is also encrypted increasing power consumption
Solution Approach 1:
The patent further segments image frame data into line-based units and applies encryption at this finer granularity level. This allows precise control over which data is encrypted while maintaining efficient processing through systematic line-by-line encryption of only necessary video content.
3Reliability
If encryption is applied to all data packets regardless of content type, then data protection coverage is improved, but system complexity increases due to unnecessary encryption operations
Solution Approach 1:
The patent implements a data type identification mechanism that recognizes different video data types (image frame data requiring encryption and auxiliary data not requiring encryption). This local differentiation simplifies the overall system by avoiding unnecessary encryption operations on non-critical data while maintaining comprehensive protection where needed.
Data Source
AI summary
This application discloses a data transmission encryption control method and apparatus, and relates to the field of media technologies. The method includes: determining that a to-be-transmitted data packet includes an encryption identifier indicating that the to-be-transmitted data packet is transmitted in an encrypted transmission mode, and encrypting the to-be-transmitted data packet. The to-be-transmitted data packet includes a video data packet. The video data packet is a video data packet obtained based on any line of video data in image frame data of the to-be-transmitted video.
