Multi-Screen Video Distribution Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for multi-screen viewing of video programs inefficiently manage network bandwidth, particularly when users access video content on both standalone and handheld devices, often resulting in unnecessary data transmission and reduced quality of content delivery.
Innovation Solution
A method and system where a server determines the distance between standalone and handheld devices, adjusting the transmission of video programs and related information based on predefined thresholds, and utilizes view change information to optimize bandwidth allocation, ensuring the best quality of content is delivered to the actively viewed device while degrading it on inactive devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system transmits video program and related information to all registered devices, then all devices can access content, but network bandwidth is wasted due to redundant transmissions
Solution Approach 1:
The system assigns different roles (primary or secondary) to different devices based on their characteristics and user behavior patterns. The primary device receives both video program and related information, while secondary devices receive only video program or only related information, creating localized optimization for each device's content reception quality
Solution Approach 2:
The content distribution is segmented into two types: video program and related information. The system selectively transmits different content types to different devices based on their primary/secondary status, dividing the transmission task to avoid redundant data transfer while ensuring all devices can access necessary content
2Manufacturing precision
If the system transmits high quality video program to all devices, then content quality is maintained, but network bandwidth consumption increases
Solution Approach 1:
The system provides high quality content (both video program and related information) selectively to the primary device, while secondary devices receive only essential content in optimized formats. This localized quality differentiation maintains excellent viewing experience on the primary device while reducing overall network bandwidth consumption
3Loss of energy
If the system monitors user view changes and adjusts content transmission, then bandwidth is optimized, but system complexity increases
Solution Approach 1:
The system implements a feedback mechanism where devices send view change information to the server, which then adjusts content transmission accordingly. When the user switches viewing devices, the server reassigns primary/secondary device roles and adjusts content distribution, creating a closed-loop system that optimizes bandwidth based on actual usage patterns
Solution Approach 2:
Devices automatically detect and report their own view change status to the server. The system uses simple status flags and automated role reassignment based on predefined rules, avoiding complex real-time monitoring while achieving effective bandwidth optimization through device-initiated feedback

AI summary
A method of receiving a video program and information related to the video program by a first device registered in a user account of a user as a standalone device at a server is disclosed. The method comprises sending location information of the first device to the server; sending a request to the server for the video program; receiving the video program; and receiving information related to the video program according the location information.
