Remote Control Bullet Screen Input via Set Top Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia comment systems, such as 'bullet screens,' are limited in allowing users to easily input comments during video presentations, as they typically require smartphone-based text inputs and are not accessible in the typical viewing area of a user's home.
Innovation Solution
A system comprising a set top box, display device, and wireless remote control input device with audio and tactile inputs, coupled to a media server via a cable television network, enables users to input voice or text comments that are contemporaneously displayed with streaming video content, allowing for easy and accessible comment input during video presentations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smartphone-based text inputs are used for bullet screens, then comments can be displayed contemporaneously with video content, but user accessibility and ease of input are limited in typical viewing areas
Solution Approach 1:
The remote control device is enhanced to serve multiple functions: it acts as both a traditional video control remote and a comment input device. The remote includes an audio input device (microphone) for voice comments, a tactile input device (keyboard) for text comments, and a wireless transceiver for communication, allowing users to input comments conveniently from their seating position without needing a smartphone
Solution Approach 2:
The set top box serves as an intermediary device that receives comments from the remote control via wireless communication and transmits them to the media server. This mediator enables communication between the user's remote control and the bullet screen system, making comment input accessible from the viewing area
2Productivity
If smartphone-based text inputs are used for bullet screens, then real-time comment display is achieved, but system complexity and device requirements increase
Solution Approach 1:
The remote control device contains built-in input capabilities (audio input device and tactile input device) that enable it to generate comments independently without requiring an external smartphone. The set top box receives these comments directly and forwards them to the media server, simplifying the system by eliminating the need for smartphone-based text input applications and browsers
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to input and view comments in real-time with video content, improving user engagement and accessibility by allowing voice or text inputs through a remote control device, enhancing the multimedia comment experience.
Implementation Method 1
The remote control input device includes a wireless transceiver and the set top box includes a radio frequency transceiver
Data Source
AI summary
The example system and method enable a user to post comments to appear as textual content in a streaming graphical content presentation. The textual content and the graphical content may be provided to the user's set top box for presentation on an associated display device and may be provided to another user's set top box for presentation on the other user's display device. Each of the users utilize a wireless remote control enabled to accept text and/or voice inputs of a comment for inclusion in the streaming graphical content. The set top box generates a comment based on the inputted text and/or voice received from the remote control. The set top box provides the generated comment to a media server which distributes textual content based on the generated comment to other set top boxes for presentation with the streaming graphical content.
