Live Broadcast Proxy via Dedicated Network Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current live broadcast services over the Internet suffer from poor quality of service (QoS) guarantees, limited uplink bandwidth, and high latency, making it difficult to support ultra-high-definition streaming such as 4K/8K, leading to frequent service disruptions and poor image quality.
Innovation Solution
A live broadcast method and system that utilizes a dedicated network with guaranteed Quality of Service (QoS) for the uplink, allowing the live broadcast client to push data through a live broadcast proxy client connected to both a home network and a dedicated network, such as IPTV, to ensure stable and high-quality streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If live broadcast data is pushed over the Internet uplink, then the live broadcast service can be accessed widely, but the service quality deteriorates due to lack of QoS guarantee, limited bandwidth, and high latency
Solution Approach 1:
The patent introduces a dedicated network as an intermediary transmission path between the live broadcast client and server. This dedicated network acts as a mediator that provides QoS guarantees and sufficient bandwidth, resolving the contradiction between wide accessibility and service stability by offering a reliable transmission channel while maintaining Internet access for broad reach
2Device complexity
If live broadcast data is pushed over the Internet uplink, then the system structure remains simple, but the image quality deteriorates due to limited uplink bandwidth
Solution Approach 1:
The dedicated network serves as an intermediary that bridges the simple Internet-based system structure with the requirement for high image quality. By introducing this intermediate transmission layer with guaranteed bandwidth and QoS, the system achieves both structural simplicity and high-quality image transmission without requiring complex reconfiguration
3Ease of manufacture
If live broadcast data is pushed over the Internet uplink, then the implementation is straightforward, but the latency increases making ultra-high-definition streaming difficult
Solution Approach 1:
The dedicated network acts as a time-efficient intermediary that reduces transmission latency compared to standard Internet uplinks. While maintaining straightforward implementation through similar protocol stacks, the dedicated network's prioritized traffic handling and sufficient bandwidth significantly reduce the time loss associated with pushing ultra-high-definition live broadcast data

AI summary
A live broadcast method includes: receiving, by a live broadcast client, a push-stream address sent by the live broadcast management server; sending, by the live broadcast client, a proxy push-stream request to a live broadcast proxy client; and sending, by the live broadcast client, collected live broadcast data to the live broadcast proxy client, and pushing the live broadcast data to a live broadcast server over an uplink of a dedicated network connected to the live broadcast proxy client.
