3D Media Content Distribution via Pixel Filtering and Transport Frame Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing quality of three-dimensional media content leads to higher bandwidth requirements, causing a significant load on networks used for media content distribution, which existing technologies struggle to efficiently manage.
Innovation Solution
A method involving a server that receives 3D image content with left and right eye frames, removes and combines pixels to form transport frames in an alternating pattern, and encodes these for transmission over an IPTV network, allowing for efficient compression and delivery of 3D media content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution three-dimensional media content is transmitted, then image quality and clarity are improved, but network bandwidth requirements increase significantly
Solution Approach 1:
The patent segments the 3D image content into multiple views (left eye, right eye, intermediate views) and processes each view separately through gradient filtering. This segmentation allows selective compression of different view components while maintaining overall image quality, reducing the total bandwidth required for transmission.
Solution Approach 2:
The patent applies gradient filtering to modify the spatial frequency parameters of the image content. By filtering out high-frequency gradient components that are less perceptible to human vision, the method reduces the amount of data that needs to be transmitted while preserving the visually important low-frequency components, thus maintaining image quality with lower bandwidth.
2Measurement precision
If more pixel data is transmitted for each frame, then image clarity is improved, but network load increases
Solution Approach 1:
The patent transforms the image data from spatial domain to gradient domain, changing the representation parameters. This transformation allows for more efficient compression because gradient information can be compressed more effectively than raw pixel data, reducing network load while maintaining the ability to reconstruct clear images at the receiver.
Solution Approach 2:
The patent generates intermediate views by synthesizing new pixel data from existing left and right eye views through gradient filtering. This copying approach allows multiple view perspectives to be transmitted with less total data than would be required to transmit each view independently at full resolution, thereby reducing network load while maintaining image clarity.

AI summary
A system that incorporates teachings of the present disclosure may include, for example, a process that includes obtaining three-dimensional image content having first and second images. The first and second images include first and second numbers of pixels. The first and second images are arranged according to a shared coordinate system to portray different perspectives of a common scene. A first portion of pixels are removed from the first image based on a filtering of the first image, resulting in a first remaining number of pixels. A second portion of pixels are removed from the second image based on positions of the first portion of pixels in the shared coordinate system, resulting in a second remaining number of pixels. The first remaining portion of pixels is combined with the second remaining portion of pixels to form a transport frame for delivery to a media processor. Other embodiments are disclosed.
