MMT Low Delay Signaling for Multimedia Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Moving Picture Experts Group (MPEG) Media Transport (MMT) protocol does not provide appropriate information for low delay consumption, which is essential for efficient delivery of multimedia content over heterogeneous IP network environments.
Innovation Solution
The implementation of a system and method for wireless communication between base stations and user equipment, where a transceiver receives packets with control messages containing a header indicating whether the message is a low delay consumption message, and processing circuitry configures packets based on the payload and message to facilitate low delay consumption of multimedia content by determining the message type and configuring the packet structure accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the MMT protocol uses standard packet-based delivery without low delay consumption signaling, then compatibility with existing network protocols is maintained, but delay in multimedia content consumption increases
Solution Approach 1:
The system performs preliminary configuration of packet structure and buffering parameters by receiving and processing low delay consumption signaling messages before actual multimedia data delivery. This allows the receiving device to pre-configure its de-capsulation buffer and packet handling logic, enabling low delay consumption without adding complex runtime processing
Solution Approach 2:
The invention changes operational parameters of the MMT protocol by introducing a specific message type (low delay consumption message) that modifies buffer management behavior. The receiving device adjusts its packet buffering and processing parameters based on the received signaling, transitioning from standard delay-tolerant operation to low delay consumption mode
2Speed
If the system configures packets based on low delay consumption messages, then delivery speed of multimedia content improves, but processing complexity increases
Solution Approach 1:
The receiving device performs preliminary configuration of its packet processing logic when the low delay consumption message is received, setting up buffer parameters and processing rules in advance. This eliminates the need for complex real-time decision-making during data delivery, maintaining high speed while managing processing complexity
Solution Approach 2:
The low delay consumption message acts as an intermediary that carries configuration information from the transmitting device to the receiving device. This message mediates the coordination between sender and receiver, enabling synchronized optimization of packet handling without requiring complex direct interaction or continuous negotiation
3Productivity
If the MMT protocol adds signaling for low delay consumption, then multimedia content delivery efficiency improves, but protocol complexity increases
Solution Approach 1:
The invention segments the protocol signaling into distinct, well-defined message types with specific purposes. The low delay consumption message is a separate, standardized signaling element that can be independently processed, allowing the protocol to gain functionality without creating monolithic complexity. Each message type handles a specific aspect of delivery optimization
Solution Approach 2:
The low delay consumption message serves multiple functions: it signals the receiving device to adopt low delay buffering, triggers configuration of packet processing parameters, and coordinates timing between transmitter and receiver. This multi-functionality achieves delivery efficiency improvement through a single, versatile signaling mechanism rather than multiple separate protocols

AI summary
Methods and apparatuses for wireless communication between at least one base station and user equipment, the user equipment including a transceiver and processing circuitry. The transceiver is configured to receive a packet comprising a control message with a header and a payload related to fragments of multimedia content. The header includes a message identifier indicating whether the control message is a low delay consumption message, a length of the controller message, and a version of the control message. The processing circuitry is configured to determine whether the control message is the low delay consumption message based on the message identifier. The processing circuitry is also configured to, responsive to the control message being the low delay consumption message, configure the packet based on the payload and the control message before receiving headers of the fragments of the multimedia content.
