Solution Overview
Problem
The existing network architecture for streaming media services is complex and costly due to the need for multiple servers and switches, which complicates the processing and transmission of live program contents across different terminal types.
Innovation Solution
A network device with an embedded streaming function module that receives and processes streaming media service signals directly from an encoder, eliminating the need for Ethernet switches and streaming servers, and includes active and standby input ports for fault detection and switchover, simplifying the network architecture and reducing operating costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple servers and switches are deployed to support different terminal types, then the system can provide multi-screen integrated services, but the network architecture becomes more complicated and operating costs increase
Solution Approach 1:
The patent combines the functions of multiple servers and switches into a single integrated network device. The network device includes an embedded streaming function module that can directly receive coded signals from encoders and provide services to different terminal types, eliminating the need for separate streaming servers and reducing network architecture complexity while maintaining multi-screen integrated service capability
Solution Approach 2:
The network device is designed with universal functionality to serve multiple terminal types (traditional STB terminals and other terminals like smart phones, netbooks, computers). The embedded streaming function module can handle different service modes (MPEG2-TS over RTP for STB, HTTP for other terminals) within a single device, providing adaptability without requiring separate specialized servers for each terminal type
2Adaptability or versatility
If multiple servers and switches are deployed, then the system can process streaming media services for different terminals, but operating costs increase
Solution Approach 1:
The patent merges the functions of multiple network devices (streaming servers, switches) into a single network device with an embedded streaming function module. This consolidation reduces the quantity of network devices from multiple separate components to one integrated unit, thereby reducing operating costs while maintaining the ability to process streaming media services for different terminal types
3Productivity
If an active input port is used to receive streaming media packets, then the system can process live program contents, but fault detection and system maintenance become difficult
Solution Approach 1:
The patent implements a standby input port that is pre-configured and ready to take over from the active input port in case of failure. The standby port is prepared in advance with the necessary configuration, allowing for immediate failover without interrupting service. This preliminary preparation of the standby port enables easy fault detection and maintenance, as the system can switch to the standby port when the active port needs to be serviced or when a fault is detected

AI summary
A system for processing a streaming media service and a method and a network device thereof are provided. The system includes a network device and an encoder. The network device has an embedded streaming function module. The encoder includes two egress ports, where the two egress ports of the encoder are connected to an active input port and a standby input port of the network device respectively. The encoder is configured to: receive a streaming media service signal, encode the streaming media service signal to generate a streaming media service coded signal, and send the streaming media service coded signal to the network device. The network device is configured to receive, by using the embedded streaming function module through the active input port or the standby input port, a streaming media service coded signal sent by the encoder, and provide the streaming media service coded signal for a terminal.
