Interactive Sports Video System with On-Demand Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional viewing experiences, including television and early Internet video, lack interactivity and flexibility, restricting viewers to a linear broadcast schedule and limited control over content timing, especially for sports events.
Innovation Solution
The development of an interactive sports video system that allows viewers to access and navigate sports video streams online, using sport-specific definition files, game annotation files, and user interfaces to enable features like instant replay, camera angle changes, and social sharing, without the need for prerecording, leveraging improved internet bandwidth and video protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional television broadcasting is used, then viewers can access sports content, but viewers are restricted to linear broadcast schedules with limited control over timing and content selection
Solution Approach 1:
The system transitions from static linear broadcasting to dynamic on-demand access, allowing viewers to control playback timing, pause, rewind, and fast-forward sports content at will, making the viewing experience adaptable to individual schedules
Solution Approach 2:
The video stream is segmented into discrete playable units that can be independently accessed and controlled, enabling viewers to navigate to specific moments in the sports event rather than being constrained to continuous linear playback
2Adaptability or versatility
If early Internet video systems were used, then viewers could access video online, but viewers experienced long buffer waits, low resolution, and limited ability to select video parts
Solution Approach 1:
The system pre-loads and buffers video data in advance during idle periods or using available bandwidth, so that when viewers request specific video segments, the content is already prepared and can be delivered immediately without long wait times
Solution Approach 2:
The system dynamically adjusts video delivery parameters including resolution, bitrate, and buffer size based on available network bandwidth and viewer preferences, enabling high-definition playback without prolonged buffering by optimizing data transmission efficiency
3Adaptability or versatility
If interactive features are added to sports video viewing, then user engagement is improved, but system complexity increases
Solution Approach 1:
The system implements a universal interactive framework that handles multiple functions (replay, slow-motion, multi-angle viewing, social sharing) through a common architecture, reducing overall system complexity by avoiding separate dedicated systems for each feature
Solution Approach 2:
The system introduces an intermediary layer between the video stream and the viewer interface that manages complex interactions, allowing sophisticated features to be implemented without directly complicating the core video delivery infrastructure
Data Source
AI summary
A primary video stream of a sporting event may be provided via the Internet. In addition, at least one secondary video stream of the sporting event may be provided via the Internet. Moreover, metadata corresponding to the primary video stream and the at least one secondary video stream may be provided via the Internet. The primary video stream, the at least one secondary video stream, and the metadata may be utilized to provide interactive viewing of the sporting event.
