Synchronized Broadcast Playback With Live Commentary Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving-image delivery services do not allow users to enjoy video content together with the commentary of a favorite deliverer, limiting the ability to watch a video content and its live broadcast simultaneously.
Innovation Solution
A moving-image delivery system that includes a playback device and server, allowing the playback device to transmit a delivery request for live moving images and display both the video content and live moving image on the same screen, with the server delivering the live moving image upon request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users watch video content through existing moving-image delivery services, then they can enjoy video content, but they cannot simultaneously watch the live broadcast with deliverer commentary
Solution Approach 1:
The system merges the video content playback and live broadcast delivery into a single integrated service. The moving-image delivery server delivers both the video content and the live moving image of the deliverer's commentary, allowing users to watch both simultaneously in one interface rather than requiring separate services.
Solution Approach 2:
The moving-image delivery server is designed to perform multiple functions: it can deliver recorded video content, deliver live moving images of deliverers, and coordinate these deliveries to occur simultaneously. This multi-functionality enables the system to provide both video content and live commentary through a single platform.
2Adaptability or versatility
If the system delivers both video content and live moving image simultaneously, then user engagement is enhanced, but system complexity increases
Solution Approach 1:
The moving-image delivery server acts as an intermediary that receives the video content and the live moving image separately, coordinates their delivery timing, and delivers both to the user's device. This mediator approach simplifies the overall system architecture by centralizing the coordination logic in one component rather than requiring complex peer-to-peer synchronization between multiple independent systems.

AI summary
A moving-image delivery system including a recording/playback device 1 for playing back television broadcast programs and live moving images, and a moving-image delivery server 5 for delivering live moving images. The recording/playback device 1 is provided with: a delivery request unit 12 for transmitting a delivery request that requests the delivery of live moving images of a television broadcast program, the delivery request including meta-information for specifying a television broadcast program when playing back television broadcast programs; and a display control unit 13 for, upon receiving the delivery of a live moving image, outputting a display screen image in which the television broadcast program and the live moving image are displayed in the same screen image. The moving-image server 5, upon receiving a delivery request, starts delivering live moving images of the television broadcast program specified by the meta-information included in the delivery request.
