3D Multimedia Encoding with Null Frames for HD Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for transmitting high definition 3-D multimedia content fail to meet resolution expectations due to the need to squeeze or interleave left-eye and right-eye images into a single frame, resulting in lower image quality compared to standard definition video.
Innovation Solution
The method involves encoding and transmitting 3-D multimedia content at a frame rate twice that of standard content, using null frames to maintain high definition resolution, and employing a synchronization signal to distinguish between left-eye and right-eye frames, ensuring each image type utilizes full frame resolution and is displayed sequentially.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If left-eye and right-eye images are squeezed or interlaced into a single frame for transmission, then transmission compatibility with conventional digital interfaces is achieved, but image resolution deteriorates
Solution Approach 1:
The patent segments the transmission stream into separate left-eye and right-eye frame sequences, allowing each eye's image to occupy its own full-resolution frame rather than being compressed within a single frame. This segmentation enables full HD resolution (1920x1080) for each eye while maintaining compatibility with conventional digital interfaces through the use of null frames and synchronization signals.
Solution Approach 2:
The patent introduces a temporal dimension by transmitting frames at twice the standard frame rate (e.g., 120 fps instead of 60 fps). This allows left-eye and right-eye frames to be transmitted alternately in time rather than being compressed spatially within a single frame, thereby preserving full resolution for each eye while maintaining interface compatibility.
2Manufacturing precision
If frame rate is doubled to transmit both left-eye and right-eye frames separately, then full resolution for each image is maintained, but data transmission rate increases
Solution Approach 1:
The patent extracts and removes redundant data by transmitting only essential synchronization information through null frames containing synchronization signals. Instead of transmitting complete duplicate frames for each eye, the system transmits full-resolution content frames alternately for left and right eyes, with null frames providing minimal synchronization overhead, thereby reducing overall data transmission requirements while maintaining full resolution.
3Manufacturing precision
If null frames are inserted to maintain frame rate and resolution, then high definition quality is preserved, but frame sequence complexity increases
Solution Approach 1:
The patent implements self-service through automatic synchronization signal detection and frame type identification. The display device automatically detects synchronization signals within null frames and autonomously determines the sequence pattern (e.g., left-eye frame, right-eye frame, null frame) without requiring complex external control systems. This self-service approach simplifies the overall system architecture while maintaining HD quality through proper frame sequencing.

AI summary
One particular implementation may take the form of a method and system for decoding 3-D multimedia content. In one example, the present invention may take the form of a method of decoding 3-D multimedia content encoded with at least content frames and null frames. The method may operate to receive the 3-D multimedia content, extract at least one content frame, at least one null frame, and display information. The method may further operate to reconstruct the content and null frames in a display-sequential manner using the display information to indicate the display order of the at least one content frame. In some examples, the method and system for encoding and decoding multimedia content may encode the multimedia content such that the at least one null frame may not be displayed by a display device.
