Wireless Stream Control Information for Protocol Version Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional communication systems lack flexibility and efficiency in signaling and versioning, particularly in handling unforeseen changes and new technology innovations, with existing data and control protocols like XML, JSON, and YAML being inefficient in bit usage and not adequately supporting bandwidth requirements in multimedia streaming.
Innovation Solution
A system and method for generating and transmitting control information using a tree-based data structure with a service descriptor that specifies protocol versions and location information, allowing audiovisual devices to ignore incompatible data and dynamically configure communication layers based on channel characteristics and received instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional communication protocols (XML, JSON, YAML) are used for control information, then human readability is improved, but bandwidth efficiency deteriorates due to excessive overhead
Solution Approach 1:
The patent extracts only the essential control information needed for device configuration and presentation, removing unnecessary overhead from traditional text-based protocols. The service descriptor and control information packets transmit only critical parameters (timing, synchronization, format) in a compact binary format, eliminating verbose text while maintaining operational effectiveness.
Solution Approach 2:
The patent changes the parameter representation from human-readable text to compact binary encoding. Control information is transmitted using efficient bit fields and enumerated values rather than text strings, dramatically reducing bandwidth consumption while preserving all necessary configuration data for audiovisual device operation.
2Device complexity
If predefined data formats are used in traditional communication systems, then system simplicity is improved, but adaptability deteriorates when unforeseen changes or new technologies arise
Solution Approach 1:
The patent segments control information into modular components: service descriptor, control information packets, and extensible parameter fields. This segmentation allows individual elements to be updated or extended without redesigning the entire system, enabling forward compatibility while maintaining overall system simplicity through consistent modular interfaces.
Solution Approach 2:
The patent implements dynamic adaptability through versioned service descriptors and extensible control information structures. The system can dynamically incorporate new parameters and technologies by adding fields to the extensible parameter structure, allowing the communication protocol to evolve without breaking existing implementations.
3Reliability
If all control information is transmitted to ensure complete configuration, then configuration completeness is improved, but transmission efficiency deteriorates due to unnecessary data
Solution Approach 1:
The patent applies partial action by transmitting only the specific control information relevant to each audiovisual device's configuration needs. The service descriptor and control information packets include only necessary parameters (timing, synchronization, format) rather than exhaustive configuration data, reducing transmission overhead while ensuring complete functional configuration.
Solution Approach 2:
The patent implements self-service through selective transmission where the receiving device can autonomously determine which control information parameters are applicable to its capabilities. The extensible parameter structure allows devices to process only relevant configuration data while ignoring unnecessary fields, improving transmission efficiency without sacrificing configuration completeness for supported features.
Data Source
AI summary
Control information for configuring an audiovisual device to present multimedia content according to a first service type may be generated. A method may include generating first control information for configuring an audiovisual device to decode a multimedia stream, generating first data that indicates a structure of the first control information, and transmitting the first data and the first control information. The first control information may be generated according to a first protocol version. Second data and second control information may be similarly generated and transmitted according to a second protocol version. Disclosed techniques may facilitate receiving devices to determine whether they support received wireless transmissions and decode the transmissions based on the control information.
