Multimedia Traffic Information Encoding and Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing traffic information do not effectively allow users to visually and audibly recognize traffic situations in a convenient manner, especially in dynamic environments like downtown areas during holidays.
Innovation Solution
A method and apparatus that encode and decode multimedia information messages with video and audio attributes associated with traffic information, using service component identifiers, message identifiers, and version numbers to provide visual and auditory feedback about traffic conditions, enabling easy access and billing for multimedia data through different transmission channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traffic information is provided through traditional text-based broadcast signals, then the information can be transmitted efficiently, but users cannot visually and audibly recognize traffic situations in a convenient manner
Solution Approach 1:
The patent combines multiple types of information (traffic status, location, video, audio) into a single integrated multimedia message structure. The message management container aggregates diverse data elements with different identifiers and types, allowing simultaneous transmission of text, video, and audio information through one broadcast signal, thereby improving ease of recognition without significantly reducing transmission efficiency
Solution Approach 2:
The patent introduces a message management container as an intermediary structure that mediates between different information sources and the user's reception device. This container organizes and coordinates multiple information elements (traffic information messages, video objects, audio objects) with unique identifiers, enabling efficient processing and presentation of diverse data types without requiring separate transmission channels for each information type
2Ease of operation
If multimedia information with video and audio attributes is added to traffic information messages, then users can visually and audibly recognize traffic situations, but the complexity of encoding and decoding the information increases
Solution Approach 1:
The patent segments the multimedia information into distinct, independently identifiable components within the message management container. Each video object and audio object is assigned a unique identifier that separates it from other information elements, allowing the receiving device to process and decode only the necessary components based on user needs, thereby reducing overall decoding complexity while maintaining comprehensive information availability
Solution Approach 2:
The patent implements preliminary organization of multimedia information during the encoding phase by pre-assigning unique identifiers and structuring data according to predefined message management container formats. This preliminary structuring eliminates the need for complex real-time parsing at the receiving end, as the organized structure guides the decoding process, thereby reducing operational complexity while enabling rich multimedia content delivery
3Ease of operation
If reference information specifying traffic information messages is recorded in the multimedia information message, then users can easily access associated traffic information, but the size of the information message increases
Solution Approach 1:
The patent extracts essential identification parameters (service component identifier, message identifier, version number) from the full traffic information messages and incorporates only these condensed reference elements into the multimedia information message. This extraction approach provides sufficient referencing capability with minimal data overhead, enabling easy access to complete traffic information through the reference identifiers without unnecessarily increasing message size
Solution Approach 2:
The patent transforms the complete traffic information messages into a condensed parameter set for referencing purposes. By changing the representation from full message content to key identification parameters (service component identifier, message identifier, version number), the system achieves efficient referencing with reduced data volume, maintaining ease of access while minimizing the increase in information message size
Data Source
AI summary
Encoding and decoding of application information is disclosed. An encoding method includes creates multimedia object information on video and/or audio data related to content carried by a traffic information message provided through traffic information service, creates reference information indicating the traffic information message, and organizes a multimedia information message that includes the multimedia object information and the reference information. While using a traffic information provided by a traffic information service, a user can, if necessary, recognize visually and/or audially a special traffic situation of which information is provided by a traffic information service.
