IPTV Broadcast Controller Mixing Remote User Video Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interactive IPTV broadcasting systems do not allow broadcasters to synthesize user-generated videos into broadcast content in real-time and transmit them on IPTV channels, limiting true user participation.
Innovation Solution
A system and method that includes a broadcast controller for reserving IPTV channel time, notifying users for participation, and controlling the integration of user videos into the broadcast, with a media server relaying and mixing user and broadcaster video and audio traffic, and a platform server for multicasting broadcast streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a broadcaster invites guests to a studio for broadcasting, then the broadcast content variety is improved, but the broadcasting cost increases
Solution Approach 1:
The patent uses video copying technology to capture and transmit user videos from remote locations to the broadcast studio. Instead of requiring physical guest presence, the system creates video copies of users that can be integrated into the broadcast, thereby reducing travel and accommodation costs while maintaining content variety.
Solution Approach 2:
The patent introduces a video communication system as an intermediary between remote users and the broadcast studio. This intermediary technology enables real-time video transmission and integration, allowing users to participate in broadcasts without physically being present in the studio, thus reducing costs while preserving content diversity.
2Adaptability or versatility
If multiple user videos are integrated into broadcast in real-time, then user participation is improved, but the system complexity increases
Solution Approach 1:
The patent employs a universal video processing platform that can handle multiple user video streams simultaneously. This multi-functional system is capable of receiving, processing, and integrating videos from numerous users through a single standardized interface, thereby enabling broad user participation without proportionally increasing system complexity.
Solution Approach 2:
The patent replaces complex manual video switching and integration operations with automated electronic systems. The video processing platform automatically manages multiple video streams, performs real-time mixing and switching, and integrates user videos into the broadcast without requiring complex mechanical or manual intervention, thus reducing operational complexity despite handling multiple participants.
3Productivity
If user videos are processed and integrated in real-time, then the broadcasting efficiency is improved, but the processing time requirement increases
Solution Approach 1:
The patent implements preliminary encoding and compression of user videos before they are transmitted to the broadcast studio. Users' videos are pre-processed with appropriate codecs and formatting, so that when the videos arrive at the studio, minimal additional processing is required for integration into the broadcast, thereby reducing real-time processing time requirements while maintaining broadcasting efficiency.

AI summary
There is provided a interactive IPTV broadcasting service system of user participation, the system including: a broadcast controller reserving time of IPTV broadcast channels to perform an IPTV broadcast according to the reserved time, notifying user participation to accept the user participation during the broadcasting service, and controlling so that video of the user making a request for participation in broadcasting is included in video of the broadcast in progress, and then broadcast, a plurality of clients each notifying the broadcast controller of the request of the corresponding user when the participation in broadcasting is requested according to a selection of the IPTV broadcasting user and generating video and audio traffic of the corresponding user, and a media server relaying the users' participation in broadcasting between the broadcast controller and the clients, and receiving and mixing video and audio traffic of a broadcaster and the video and audio traffic of each of the users making the requests for the participation in broadcasting. Accordingly, the broadcaster can synthesize videos of users into broadcast contents.
