Interactive Multimedia Service System for Real-Time Broadcast Participation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interactive multimedia services using mobile terminals are limited to restricted real-time participation through text messages and voice communication, lacking the ability to upload multimedia content and interactively engage with broadcast programs in a more immersive manner.
Innovation Solution
An interactive multimedia service system and method that enables mobile terminals to create and encode multimedia content in real-time, which is received and synthesized with on-air broadcast programs by a broadcasting station server, allowing for real-time video information exchange and participation, and broadcasting the synthesized program back to mobile terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile terminals use text messages and voice communication for interactive services, then users can participate in broadcast programs in real time, but the interactive services are very restricted
Solution Approach 1:
The patent transitions from traditional text/voice interaction (1D communication) to multimedia content sharing (3D communication with video, audio, and data dimensions). Mobile terminals capture and transmit video content through cameras and microphones, adding spatial and sensory dimensions to the interaction, thereby dramatically expanding service versatility while maintaining real-time participation.
Solution Approach 2:
The system changes the parameters of communication by enabling video encoding and transmission from mobile terminals. The video quality, resolution, and format parameters are dynamically adjusted based on network conditions and terminal capabilities, allowing rich multimedia interaction without compromising real-time performance.
2Adaptability or versatility
If mobile terminals transmit multimedia contents in real time, then user engagement with broadcast programs is enhanced, but system complexity increases
Solution Approach 1:
The base station acts as an intermediary between mobile terminals and the broadcast system. It receives video streams from multiple terminals, performs centralized processing including encoding and multiplexing, and distributes the synthesized content to the broadcast network. This intermediary approach simplifies terminal design while enabling complex real-time multimedia interactions.
Solution Approach 2:
The patent merges multiple video streams from different mobile terminals into a single synthesized broadcast signal. The base station combines these inputs with traditional broadcast content, creating a unified output that integrates user-generated content with professional programming, thereby managing complexity through consolidation.
3Adaptability or versatility
If settop boxes interwork with PSTN and ADSL for interactive services, then digital broadcasting interactivity is enabled, but the transmission rate of return channels is limited
Solution Approach 1:
Instead of relying on limited return channels from set-top boxes to transmit interaction data, the patent inverts the approach by using the forward broadcast channel to transmit synthesized video content from mobile terminals. This reverses the traditional data flow direction, utilizing the high-capacity forward channel rather than the constrained return channel, thereby enabling rich interactive services without bandwidth limitations.

AI summary
Disclosed is related to an interactive multimedia service system and method thereof using mobile station that is enable to see a broadcasting with real time/non-real time. A broadcasting station broadcasts a multimedia contents composed of the broadcasting contents being broadcasted and the other multimedia contents generated by the mobile station, and transmits the composed multimedia contents to the mobile station. Therefore, the user of the mobile station can see the broadcasting, which the user of mobile station participates in the interactive broadcasting with real time/non-real time.
