Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing MPEG-2 transport stream technology is inefficient in IP-based networks, and the current MMT standard's Measurement Configuration (MC) message lacks sufficient information for precise measurement of transport metrics, leading to inaccurate delivery control.
Innovation Solution
An apparatus and method for generating an expanded MC message with enhanced measurement mode and period settings, including immediate start, predetermined time, and condition-based measurement options, along with improved address formats for measurement reports, to accurately transmit and receive MMT transport data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the MC message uses basic measurement timing information, then the message structure is simple, but the measurement precision is insufficient for accurate transport metrics
Solution Approach 1:
The measurement timing information is segmented into distinct fields: measurement_start_time (32 bits), measurement_stop_time (32 bits), and measurement_period (32 bits). This segmentation allows precise specification of measurement parameters while maintaining clear message structure organization.
Solution Approach 2:
The patent adds temporal dimensionality to the MC message by introducing explicit start time, stop time, and period fields. This transforms the measurement timing from implicit or basic indicators to precise temporal specifications, enabling accurate measurement scheduling without excessive complexity.
2Loss of information
If the MC message includes detailed measurement timing information, then the measurement precision is improved, but the loss of information is reduced
Solution Approach 1:
The measurement timing parameters (start time, stop time, period) are predetermined and encoded in the MC message before transmission. This preliminary encoding ensures that the receiving entity has all necessary timing information in advance, eliminating information loss without requiring complex real-time negotiation or additional messaging.
3Productivity
If the measurement timing information is expanded with start time, stop time, and period fields, then the productivity of measurement operations is improved, but the device complexity increases
Solution Approach 1:
The patent changes the parameters of measurement timing from basic or implicit values to explicit, quantifiable fields (start time, stop time, period). This parameter transformation enables automated measurement scheduling and processing, significantly improving operational productivity while the structured field-based approach keeps the message complexity manageable.

AI summary
A method of transmitting a Moving Picture Experts Group (MPEG) Media Transport (MMT) signaling message for Measurement Configuration (MC) processing in an MMT sending entity. The method includes generating an MC message with header information by setting a measurement mode (measurement_mode), which indicates information on a measurement start time (measurement_start_time) of a measurement item in an MMT receiving entity, to one of: an immediate measurement start, a measurement start at a predetermined time, a measurement start based on a predetermined condition, and an immediate measurement stop; and transmitting an MMT packet including the generated MC message to an MMT receiving entity.
