Panoramic Video Server Segmentation for Set-Top Box Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing set-top box (STB) devices struggle to provide high-definition panoramic video services due to hardware limitations, as they require complex pre-treatment and processing of panoramic videos, which can be resource-intensive and not optimized for low-specification devices.
Innovation Solution
A method where a panoramic video server pre-treats panoramic videos by dividing and processing them into multiple segments, which are then assigned to multiple video controllers on a low-specification STB, allowing for efficient playback and perspective switching based on user input, minimizing hardware dependence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a set-top box performs complex pre-treatment processes (stitching, warping, de-warping) on panoramic videos, then high-definition panoramic video quality can be achieved, but hardware specifications and processing power requirements increase significantly
Solution Approach 1:
The server performs the complex pre-treatment processes (stitching, warping, de-warping) on panoramic videos before transmission to the set-top box. This preliminary processing at the server side eliminates the need for the STB to perform these resource-intensive operations, allowing high-definition panoramic video playback on low-specification devices
Solution Approach 2:
The patent extracts the complex processing functions from the set-top box and relocates them to the server. The server handles all pre-treatment operations including stitching multiple camera feeds, warping for perspective correction, and de-warping for distortion removal, leaving only simple decoding and playback functions for the STB
2Manufacturing precision
If panoramic videos are processed in real-time on the set-top box, then viewing quality can be maintained, but processing time and energy consumption increase
Solution Approach 1:
All video processing operations are performed in advance on the server before the video is transmitted to the set-top box. The server completes stitching, warping, and de-warping operations during video encoding or pre-processing, so that the STB receives ready-to-play high-definition panoramic video without requiring real-time processing
3Adaptability or versatility
If multiple video controllers are assigned to multiple divided panoramic videos, then perspective switching capability is improved, but device complexity increases
Solution Approach 1:
The panoramic video is divided into multiple segments or regions, with dedicated video controllers assigned to each segment. This segmentation allows independent control of different video regions, enabling smooth perspective switching by activating only the relevant video controller for the current viewing angle, thus providing versatile perspective control without requiring all controllers to operate simultaneously

AI summary
High definition panoramic videos may be facilitated by, e.g., assigning video controllers to respective panoramic videos or portions thereof; activating a first video controller assigned to a first one of the panoramic videos; and producing a first view-point perspective from the first panoramic video utilizing the activated controller.
