Dual Video Presentation for Preserving Playback Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy video presentation trick functions in media devices often result in a change of current presentation time, making it difficult for users to return to the exact point in the media content where they left off, especially when significant events occur during trick operations, leading to a frustrating viewing experience.
Innovation Solution
A dual video presentation mode is implemented, where a first presentation area continues to show the current media content, and a second presentation area shows the media content manipulated by a video presentation trick function, allowing concurrent viewing of both aspects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a video presentation trick function (pause, rewind, fast forward, jump back, jump forward) is used, then the user can control the playback speed and position of media content, but the current presentation time changes making it difficult to return to the exact point where the user left off
Solution Approach 1:
The patent creates a virtual copy of the media content presentation that runs independently from the original. This virtual presentation maintains a separate presentation time that can be manipulated by trick functions without affecting the original presentation time, allowing users to navigate through content while the original position is preserved and can be easily restored.
Solution Approach 2:
The patent introduces a virtual dimension for presentation time that is separate from the original presentation time. By creating a virtual presentation time that operates in a different dimensional space, the system allows trick functions to manipulate this virtual time without impacting the original presentation position, enabling users to explore content at different speeds while maintaining awareness of the original position.
2Ease of operation
If trick functions are used to navigate through media content, then playback control is improved, but users may miss significant events that occur during trick operations
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors the original media content for significant events (such as goals in sports, score changes, or other important moments) and provides notifications to the user even when trick functions are active. This allows users to navigate content at their own pace while staying informed about important events that occur in the original presentation.
Solution Approach 2:
The patent performs preliminary analysis of the media content to identify significant events and their timing before the user begins using trick functions. This advance preparation allows the system to track and report on important events that occur during trick operations, ensuring users don't miss critical moments regardless of their playback position or speed.
3Adaptability or versatility
If the presentation time changes during trick operations, then playback control flexibility is improved, but the complexity of managing presentation state increases
Solution Approach 1:
The patent segments the presentation system into two independent components: the original presentation and the virtual presentation. Each has its own presentation time and state management, allowing trick functions to operate on the virtual presentation without complicating the original presentation state. This segmentation isolates complexity to the virtual presentation layer while keeping the original presentation simple and stable.

AI summary
Systems and methods provide presentation control of media content. An exemplary embodiment receives media content that is currently received in a broadcasted media content stream; presents on a display a first presentation area, wherein the first presentation area presents a video portion of the media content; receives a user command that initiates a video presentation trick function; and presents in response to the user command a second presentation area, wherein the second presentation area presents the video portion of the media content in accordance with the video presentation trick function, and wherein the first presentation area and the second presentation area are concurrently presented on the display.
