Hotel Stream Routing With Multicast for Bandwidth-Limited Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hospitality environments face challenges in providing seamless entertainment services to guests, which are unique due to the nature of providing a seamless guest experience with limited network resources, especially with the increasing demand for personalized per-user content streaming.
Innovation Solution
A stream manager device that operates as an edge routing device on the hotel's network, managing content streams by converting them into broadcast or multicast streams, ensuring that only one copy of each stream is retrieved from the source, thereby reducing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personalized per-user content streaming is provided to each guest, then guest experience is improved, but bandwidth consumption increases
Solution Approach 1:
The system merges multiple unicast streams into a single multicast stream when multiple users request the same content. The stream manager device detects duplicate content requests and consolidates them into one multicast stream that can be simultaneously delivered to multiple destination devices, thereby reducing overall bandwidth consumption while maintaining personalized streaming capability.
Solution Approach 2:
The stream manager device performs multiple functions: it acts as a content request receiver, a duplicate detector, a stream converter (unicast to multicast), and a content delivery router. This multi-functionality enables the system to handle both unique and duplicate content requests efficiently, providing personalized streaming to each user while optimizing network resource utilization through intelligent stream management.
2Reliability
If multiple copies of content streams are retrieved for different users, then content delivery reliability is improved, but network bandwidth usage increases
Solution Approach 1:
The system combines multiple content stream requests into a single multicast stream when the content is identical. Instead of retrieving and transmitting separate unicast copies to each user, the stream manager creates one multicast stream that delivers the same content to multiple destination devices simultaneously, reducing bandwidth usage while ensuring reliable content delivery to all requesting users.
Solution Approach 2:
The system creates virtual copies of the content stream through multicast technology. While multiple users receive the content simultaneously (effectively copying the stream to multiple destinations), the actual content transmission occurs over a single network path using multicast protocols, thereby avoiding the bandwidth consumption of multiple separate unicast transmissions while maintaining content availability for all users.
3Adaptability or versatility
If unicast streaming is used for each user, then content personalization is improved, but network resource efficiency deteriorates
Solution Approach 1:
The system dynamically switches between unicast and multicast streaming modes based on real-time content request patterns. When a user requests content, the system initially provides it via unicast for personalization. When duplicate requests are detected, the system dynamically converts to multicast mode to improve network efficiency. This dynamic adaptation allows the system to maintain content personalization while optimizing network resource utilization based on actual usage patterns.
Solution Approach 2:
The system changes the streaming parameter from unicast to multicast when duplicate content requests are detected. This parameter change transforms the delivery mechanism from individual dedicated streams to a shared group stream, thereby improving network resource efficiency while maintaining the ability to provide personalized content to each user based on their specific requests and preferences.

AI summary
A system for a hospitality environment includes a plurality of destination devices and a first routing device in communication with the plurality of destination devices. The first routing device may receive a request for a content stream from a first destination device of the plurality of destination devices, and determine whether the content stream is currently being provided by the first routing device to a second destination device of the plurality of destination devices. When the content stream is currently being provided by the first routing device to the second destination device, the first routing device sends the content stream to the first destination device and the second destination device, and when the content stream is not currently being provided by the first routing device to the second destination device, the first routing device forwards the request for the content stream to a first network element.
