Image Processing Apparatus Offline HEVC Decoding via Stored History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for displaying HEVC images require continuous connection between image capturing apparatuses and external control apparatuses to manage royalty charges and ensure codec compatibility, which is inconvenient and prone to disconnection issues when power is turned off or interrupted.
Innovation Solution
An information processing apparatus with a communication unit, decoding unit, managing unit, receiving unit, and display control unit that extracts identification information from image files to determine codec compatibility and control decoding based on communication history, allowing for seamless display of HEVC images without constant connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous connection between image capturing apparatus and external control apparatus is maintained to manage royalty charges and ensure codec compatibility, then reliability of codec licensing is improved, but ease of operation deteriorates due to connection requirements and disconnection issues
Solution Approach 1:
The external control apparatus performs preliminary actions by storing identification information of the image capturing apparatus and communication history data before disconnection occurs. This allows the system to verify codec compatibility and manage royalty charges based on pre-collected information, eliminating the need for continuous connection while maintaining licensing reliability.
Solution Approach 2:
The system creates a copy of the identification information from the image capturing apparatus and stores it in the external control apparatus. This copied information includes device identifiers and codec capability data, which can be verified later without requiring the original device to be connected, thus solving the contradiction between reliable verification and operational convenience.
2Manufacturing precision
If codec compatibility is verified through continuous connection, then manufacturing precision of codec handling is improved, but loss of time increases due to connection maintenance requirements
Solution Approach 1:
Codec compatibility verification is performed as a preliminary action when the apparatuses are first connected. The external control apparatus stores the verification results and identification information for future use, eliminating the need for repeated connection-based verification and reducing time loss while maintaining precise codec handling.
Solution Approach 2:
The communication history information stored in the external control apparatus acts as an intermediary that carries codec compatibility verification data. This intermediary allows the system to verify codec handling precision without requiring continuous direct connection between the image capturing apparatus and external control apparatus, thereby reducing time loss.
3Ease of operation
If communication history is stored to enable offline verification, then ease of operation is improved by allowing disconnection, but device complexity increases due to additional storage and management functions
Solution Approach 1:
The managing unit in the external control apparatus is designed with multi-functionality, serving both as a communication interface and a storage system for identification information and communication history. This universal component handles multiple tasks including data storage, verification, and licensing management, thereby reducing overall system complexity despite the added functionality required for offline operation.

AI summary
An information processing apparatus comprises a decoder, a managing unit which manages storage of history information relating to communication with an image capturing apparatus, a receiving unit which, in a case of communication with the image capturing apparatus, receives an image file held in the image capturing apparatus and saves the image file to a predetermined storage unit; and a display control unit which controls a display of an image of the image file saved to the storage unit, wherein, when displaying an image file stored in the storage unit, the display control unit extracts, from the image file, identification information of the image capturing apparatus, and, based on the extracted identification information and the managed history information, determines whether or not to use the decoder to decode the image file.
