A transmission device that generates basic and extended video streams by encoding image data using prediction encoding processes, and inserts identification information into containers to facilitate decoding based on display capabilities, allowing for selective processing of video streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple high-quality format image data streams are transmitted alongside basic format streams, then image quality and adaptability to display capabilities are improved, but transmission complexity and processing overhead increase
Solution Approach 1:
The image data is segmented into multiple distinct video streams, each encoded in a specific image format (e.g., first format, second format, third format). This segmentation allows the transmitting device to provide multiple format options without requiring complex real-time format conversion, as each stream is independently encoded and transmitted with its format identification information.
Solution Approach 2:
The image data is pre-encoded into multiple different formats before transmission. The transmitting device performs the encoding work in advance, creating multiple version streams with different format characteristics (such as different color spaces, resolutions, or compression levels). This preliminary encoding action eliminates the need for complex real-time format conversion at the transmitting end, reducing transmission complexity while maintaining adaptability.
2Measurement precision
If identification information is inserted into each video stream, then decoding accuracy and format recognition are improved, but data overhead and processing load increase
Solution Approach 1:
The format identification information is extracted and placed in a dedicated data structure (such as a format indication table or metadata field) separate from the main video data payload. This extraction allows the identification information to be efficiently transmitted alongside the video streams without being embedded within each data packet, thereby reducing processing overhead while maintaining accurate format recognition.
3Adaptability or versatility
If multiple encoding formats are transmitted, then compatibility with different display devices is improved, but bandwidth consumption and transmission efficiency decrease
Solution Approach 1:
The transmitting device implements a universal transmission framework that can handle multiple image formats through a common structure. The format indication table serves as a universal index that maps different encoding formats to their respective video streams, allowing the system to accommodate various display device requirements without requiring separate transmission protocols for each format, thereby maintaining transmission efficiency while achieving broad compatibility.

AI summary
Basic format image data and the predetermined number of pieces of high-quality format image data are successfully transmitted. A basic video stream obtained by encoding basic format image data and a predetermined number of extended video streams obtained by encoding the predetermined number of pieces of high-quality format image data are generated. A container in a predetermined format including each of the video streams is transmitted. Identification information in a high-quality format corresponding to each of the predetermined number of extended video streams is inserted into a layer of the container and/or the video stream.
