Media Transcoding for Independent Wireless Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack an effective means to transmit and receive media-related content, such as video and audio, in a robust, reliable, and perceptually acceptable manner without deleteriously affecting other communications, particularly in wireless environments where latency and delay can cause significant performance degradation.
Innovation Solution
The implementation of adaptive transcoding and encoding techniques that allow for independent and selective processing of media elements, enabling different media streams to be treated differently based on their characteristics and the wireless communication channel's conditions, ensuring optimal delivery and synchronization across multiple media elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media elements are transmitted as a single bundled stream, then transmission simplicity is maintained, but quality of service and reliability deteriorate due to inability to prioritize different media types
Solution Approach 1:
The patent segments media elements into separate encoded streams rather than transmitting them as a single bundled stream. Each media element (video, audio, subtitles, etc.) is independently encoded and transmitted as a separate stream, allowing selective prioritization and quality control for different media types based on their specific requirements and channel conditions.
2Reliability
If encoding is performed for all media elements regardless of channel conditions, then quality is maintained, but transmission time and energy consumption increase
Solution Approach 1:
The patent implements dynamic encoding where encoding parameters and transmission priorities are adjusted based on real-time wireless channel conditions. The system selectively applies encoding to different media elements based on current channel quality, prioritizing critical media elements when conditions are poor and maintaining higher quality encoding when conditions are favorable, thus optimizing the balance between quality and transmission time.
Solution Approach 2:
The patent changes encoding parameters dynamically based on channel conditions and media element priorities. Different encoding schemes, bit rates, and compression levels are applied to different media elements depending on their importance and the current wireless channel state, allowing flexible adaptation to maintain quality while reducing transmission time when necessary.
3Adaptability or versatility
If single encoding scheme is used for all media elements, then system complexity is reduced, but adaptability to different media characteristics and channel conditions deteriorates
Solution Approach 1:
The patent applies local quality by using different encoding schemes and parameters for different media elements based on their specific characteristics. Video, audio, and subtitle streams receive tailored encoding treatments appropriate to their respective requirements, with each media element optimized independently rather than applying a uniform encoding approach to all media types.

AI summary
Transcoding multiple media elements for independent wireless delivery. Respective media or multimedia elements are selectively and respectively encoded and/or transcoded. Such respective and selective processing of different media elements provides for their unbundled and independent communication to one or more other devices. In one instance, different respective overlays of a display (e.g., a computer, TV, PDA display, etc.) are respectively and selectively transcoded and/or encoded to generate different respective streams that may each be handled differently as a function of any number of parameters (e.g., media element type, content, communication channel characteristic, source proximity, priority, etc.). Different types of media elements include photo/image, video, graphics, text, audio, picture-in-picture, two-dimensional (2D), three-dimensional (3D), and/or other types of media elements as may be included within a given configuration of a display. Each respective encoding and/or transcoding may be particularly optimized or tailored for a given media element type.
