Multimedia Playing Apparatus Synchronized Output via MMHL Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic books are limited in displaying multimedia content, leading to eye fatigue and storage issues due to large file sizes, and cannot easily associate and play multimedia files in different formats.
Innovation Solution
A multimedia playing apparatus and method that includes a memory for storing image, audio, and multimedia hyper link (MMHL) files, with a central processing unit (CPU) to read and control the simultaneous output of image and MMHL files based on timeline information, allowing for the playback of digital images, audio, and text.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional electronic books display only text information, then storage space is saved and device complexity is reduced, but user reading experience deteriorates and eye fatigue increases
Solution Approach 1:
The patent combines text, images, audio, and video files into a single integrated electronic book file using a unified data structure. This merging allows rich multimedia content to be stored and played back seamlessly without requiring separate storage or complex coordination between multiple files, thus maintaining device simplicity while enhancing reading experience.
Solution Approach 2:
The electronic book system is designed to handle multiple types of content (text, images, audio, video) within a single file format and playback interface. This multi-functionality allows the device to provide diverse media experiences without requiring separate applications or complex file management, resolving the contradiction between simplicity and versatility.
2Ease of operation
If special electronic books display images and play background music simultaneously, then reading experience is improved, but file size increases and storage becomes difficult
Solution Approach 1:
Multiple media files (text, images, audio) are merged into a single electronic book file with a unified data structure that includes synchronized playback timing information. This consolidation reduces the need for separate file storage and management, effectively managing file size while maintaining enhanced reading experience with multimedia content.
3Adaptability or versatility
If multimedia files in different formats are associated by using same tag or encapsulation, then playback functionality is achieved, but file size increases and compatibility with normal playing programs is lost
Solution Approach 1:
The patent segments multimedia content into distinct components (text files, image files, audio files) within the unified data structure, each with specific format identifiers. This segmentation allows the system to handle different file formats efficiently without requiring complete encapsulation, maintaining smaller file sizes while achieving broad multimedia playback compatibility.
Solution Approach 2:
The unified data structure is designed to be universally compatible with multiple media formats through standardized field definitions and synchronization mechanisms. This universal design enables the system to play back various multimedia formats without requiring format-specific encapsulation, reducing file size overhead while maintaining adaptability.
Data Source
AI summary
A multimedia playing apparatus is provided. The multimedia playing apparatus includes a memory for storing image files and multi media hyper link (MMHL) files, each MMHL file comprising timeline information, audio information, and text information; and a central processing unit (CPU) electrically connected to the memory for reading an image file from the memory, obtaining an MMHL file matched with the image file based on a name of the image file, and controlling simultaneous output of the image file and the MMHL file according to the timeline information. A multimedia playing method is also provided.
