Seat Map Video Streaming for Low-Latency Ticket Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for providing real-time data to large numbers of clients result in high server resource demands, latency issues, and vulnerability to denial-of-service attacks, particularly during peak demand for rapidly changing data, such as ticket sales, leading to stale data and user frustration.
Innovation Solution
Utilizing video streaming protocols like RTP, RTMP, RTSP, HLS, and DASH to broadcast seat maps in real-time, reducing the need for individual socket connections and minimizing latency by transmitting video streams of seat availability updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a separate socket is opened for each client to provide real-time data, then latency is reduced, but server resource demands increase significantly
Solution Approach 1:
The patent merges multiple individual client connections into a single broadcast channel. Instead of maintaining separate sockets for each client, the server publishes data changes to a single topic and all subscribed clients receive updates through this unified channel, dramatically reducing the number of concurrent connections the server must manage.
Solution Approach 2:
The patent segments the client population into groups that share common data subscription interests. Clients subscribe to specific topics based on their needs, and the server manages separate publication channels for different topics, allowing efficient targeted broadcasting without requiring individual connections to each client.
2Loss of time
If multiple sockets are managed simultaneously to reduce latency, then real-time data delivery improves, but system stability deteriorates
Solution Approach 1:
The patent combines multiple socket management operations into a single standardized publishing interface. The server uses a unified message publishing mechanism that handles all client updates through consistent protocols, eliminating the complexity of managing numerous individual socket connections and their associated synchronization issues.
3Loss of information
If concurrent socket management is implemented to provide real-time updates, then data freshness improves, but code complexity increases
Solution Approach 1:
The patent introduces a message broker as an intermediary between the data source and clients. This broker handles the complex tasks of managing subscriptions, routing messages, and maintaining connection states, while the application code simply publishes updates through a simple interface, significantly reducing code complexity.
Solution Approach 2:
The patent implements automatic acknowledgment and confirmation mechanisms where clients confirm receipt of messages and the system tracks delivery status. This feedback loop ensures data freshness without requiring complex manual synchronization logic in the application code.
4Use of energy by moving object
If blocking I/O operations are used for socket management, then resource consumption decreases, but processing efficiency deteriorates
Solution Approach 1:
The patent implements non-blocking I/O operations that allow the server to continue processing other tasks while waiting for socket operations to complete. Multiple operations proceed concurrently without one blocking another, maintaining high processing efficiency while managing resources efficiently through asynchronous execution.
Data Source
AI summary
Systems and methods for streaming images are described. A venue seat map is accessed from a data store. A current status of seats rendered in the seat map is accessed from memory. The seat map is updated to indicate the current status. A video stream comprising frames is generated, using a real time protocol, comprising the updated seat map indicating the current status of seats rendered in the seat map. The updated seat map is streamed in real time via the video stream to user device clients. A selection of a seat via the updated seat map is received via a message. A seat token for the selected seat is associated in memory with user. The seat map is updated to indicate a change in status of the selected seat in the seat map. The updated seat map is streamed as a video stream to clients hosted on user devices.
