Current 5G broadcast technologies face limitations in efficiently transmitting high-quality media content with low latency and widespread availability of multimedia services to multiple users, particularly in mobile terminals, due to constraints in network performance and real-time data transmission protocols.
Innovation Solution
A media data processing method and device that includes a receiver configured to receive multicast data over an IP network, with components for decoding signaling information, parsing multimedia data, and synchronizing service data, enabling efficient transmission of high-definition content and real-time live broadcasting through a combination of streaming and file-based services, integrated with 5G core infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multicast data is transmitted over IP network for 5G broadcast services, then widespread availability of multimedia services to multiple users is achieved, but network performance constraints and high latency occur
Solution Approach 1:
The receiver divides multicast data into two separate processing paths: streaming service data and file-based service data. The streaming service parser handles real-time multimedia content while the download service parser processes file downloads, allowing simultaneous processing without mutual interference and reducing overall latency
Solution Approach 2:
The component synchronizer pre-synchronizes timing information from both streaming and file-based services before actual media playback. By advance synchronization of service data timestamps and sequence numbers, the system prepares for seamless real-time delivery without last-minute delays
2Manufacturing precision
If signaling information is decoded and service data is synchronized for high-quality media transmission, then high-definition media content with low latency is achieved, but device complexity increases
Solution Approach 1:
The component synchronizer serves multiple functions simultaneously: it synchronizes timing between streaming and file-based services, manages service data sequencing, coordinates parser operations, and ensures timestamp alignment. This multi-functionality reduces the need for separate dedicated components for each function
Solution Approach 2:
The signaling decoder and component synchronizer work as an integrated processing unit that combines signaling information decoding with service data synchronization in a single coordinated workflow, reducing the number of separate processing stages and associated complexity
3Productivity
If multiple parsers process streaming and file-based services simultaneously, then real-time live broadcasting is supported, but processing overhead increases
Solution Approach 1:
The system dynamically allocates processing resources between the streaming service parser and download service parser based on real-time service requirements. When live broadcasting is active, the streaming parser receives higher priority; when file downloads are needed, the download parser is activated, optimizing energy usage based on actual operational needs

AI summary
A media data processing method according to embodiments may comprise the steps of: receiving a signal including multicast data on the basis of a network, wherein the network includes an Internet protocol (IP) network, the signal includes a packet containing multicast data, and the packet includes signaling information for the multicast data; decoding the signaling information; parsing the multicast data; parsing a file from the packet; parsing announcement information associated with the multicast data from the packet; and synchronizing service data of the multicast data on the basis of the multicast data and the file.
