Solution Overview

Problem

Conventional systems fail to synchronize user inputs with live content during replay, leading to cluttered and missed relevant inputs in replayed content.

Innovation Solution

A method and processing unit that synchronize live content with user inputs using timestamps and spatial stamps, perform context mapping, and modify inputs to ensure relevance and preference alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user inputs are embedded with live content during replay, then user inputs are preserved in replayed content, but the replayed content becomes cluttered and relevant inputs are missed

Engineering Contradiction:
Improvepreservation of user inputs in replayVSAvoidclutter in replayed content
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent segments user inputs into discrete data structures with individual timestamps and spatial stamps. Each input is treated as a separate entity that can be independently synchronized with specific segments of live content, allowing selective inclusion without cluttering the entire replay stream.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces timestamp and spatial stamp data structures as intermediaries between user inputs and live content. These intermediaries enable precise synchronization and context mapping, allowing the system to determine which inputs should be embedded with which content segments, thereby avoiding unnecessary clutter while preserving relevant inputs.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If all user inputs are included in replayed content, then completeness of user interaction is maintained, but user experience deteriorates due to clutter and missed relevant inputs

Engineering Contradiction:
Improvecompleteness of user interaction dataVSAvoiduser experience during replay
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent implements context mapping that provides feedback mechanisms to determine which user inputs are relevant to specific live content segments. By analyzing contextual relationships between inputs and content, the system can selectively embed only those inputs that enhance user experience during replay, filtering out redundant or irrelevant inputs.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent performs preliminary synchronization of user inputs with live content segments before replay using timestamp and spatial stamp data. This advance preparation allows the system to pre-determine which inputs should be associated with which content segments, ensuring that during replay, only contextually relevant inputs are embedded, thereby maintaining completeness while improving user experience.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method and processing unit for creating and rendering synchronized content for content rendering environment are described in present disclosure. Initially, live content rendered to users in content rendering environment is received. Further, inputs from first user, and optionally from second users is collected during rendering of live content. The inputs comprises user inputs provided in at least one of virtual environment and user actions in real-world environment. Inputs are collected along with at least one of corresponding time stamp and corresponding spatial stamp in content rendering environment. Upon collecting inputs, live content is synchronized with the inputs based on at least one of the time and spatial stamp, and context mapping of the inputs with segments of the live content to output a synchronized content. By rendering such synchronized content to the user, replication of live rendering of the content may be experienced by the user.
