Multimedia Data Backup via Segmented Contact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact person formats in smartphones are limited, leading to issues such as distortion and loss of multimedia data like head portraits during backup and transmission, failing to meet user requirements for frequent data backup and storage.
Innovation Solution
A multimedia data backup method that allows for full or selective backup of contact person information, including head portraits, using a user terminal with a display area and storage medium, which checks available storage space and prompts users if space is insufficient, enabling seamless backup and synchronization across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing contact person format (.vcf) is used to store contact information, then contact person information can be stored, but multimedia data such as head portraits cannot be stored properly and may be distorted
Solution Approach 1:
The patent segments contact person information into two distinct parts: basic contact information (stored in .vcf format) and multimedia data (stored separately in a database). This segmentation allows each part to be stored in the most appropriate format, with basic information maintaining format compatibility and multimedia data achieving proper storage without distortion.
Solution Approach 2:
The patent introduces a mapping relationship as an intermediary between contact person information and multimedia data. This mapping table stores the correspondence between contact person identifiers and multimedia file paths, enabling the system to link basic contact information with associated multimedia files without compromising either the format compatibility or the multimedia quality.
2Productivity
If contact person information is frequently backed up using existing formats, then contact information can be transmitted, but head portrait information is lost during transmission process
Solution Approach 1:
The patent performs preliminary action by pre-storing multimedia data in a database before backup operations. When backup is needed, the system retrieves the mapping relationship and associates multimedia file paths with contact person information, ensuring that head portrait information is included in the backup package before transmission occurs, thus preventing information loss during the backup process.
3Adaptability or versatility
If multimedia data is stored in contact person information, then user requirements for storing head portraits can be met, but storage space consumption increases
Solution Approach 1:
The patent extracts multimedia data from the contact person information structure and stores it separately in a database. Only the mapping relationship (which occupies minimal space) is stored within the contact person record, while the actual multimedia files are stored externally. This extraction significantly reduces storage space consumption while maintaining complete contact person information with multimedia capabilities.

AI summary
The present disclosure discloses a multimedia data backup method, a user terminal and a synchronizer. The method includes: triggering a first user operation, which is used for acquiring configuration data; displaying the configuration data in the display area in response to the first user operation, and selecting a backup mode from the configuration data; triggering a second user operation, which is used for executing data backup processing corresponding to the backup mode; and searching multimedia data corresponding to the backup mode in response to the second user operation, and backing up the multimedia data to the storage medium when it is detected that an amount of free storage space of the storage medium is matched with an amount of the searched multimedia data.
