CCTV Language Display Offset Memory Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closed circuit television (CCTV) surveillance systems face challenges in efficiently supporting multiple languages, leading to increased memory requirements, system complexity, and impaired user understanding due to the need for redundant code and storage of character font data for languages like Chinese and Japanese.
Innovation Solution
A system and method that allows simultaneous display of multiple languages by storing character data with offset values in memory, enabling efficient programmatic code that minimizes the need for duplicate code across languages, using a memory arrangement with a main unit, switch, and monitor card to generate composite video signals with overlay data for selected languages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple languages are supported in existing CCTV systems, then language versatility is improved, but memory requirements and system complexity increase due to redundant code and character font data storage
Solution Approach 1:
The patent implements a universal memory structure where a single memory location can serve multiple languages through offset addressing. The character data is organized such that the same memory address structure can retrieve characters from different languages by applying language-specific offsets, eliminating the need for separate storage structures for each language and reducing overall system complexity
Solution Approach 2:
The patent embeds multiple language character sets within a single memory structure using offset values. Each language's character data is nested within the same memory space, with language-specific offsets allowing the system to access the appropriate character set without requiring separate, independent storage areas for each language
2Adaptability or versatility
If multiple languages are supported in existing CCTV systems, then language versatility is improved, but memory requirements increase due to redundant code and character font data
Solution Approach 1:
The patent merges multiple language character sets into a single unified memory structure. By combining the character data for different languages into one memory space and using offset addressing to access language-specific characters, the system reduces total memory requirements compared to having separate, redundant storage areas for each language
Solution Approach 2:
The memory structure is designed to be universal, serving multiple languages through a single storage area. The same memory locations can be accessed for different languages by applying appropriate offsets, making the memory system multi-functional and eliminating the need for language-specific duplicate storage
3Adaptability or versatility
If redundant code is used to support multiple languages, then language versatility is improved, but programming efficiency decreases due to code duplication
Solution Approach 1:
The patent creates a universal code structure that can handle multiple languages without duplication. The same programming logic and memory access routines work for all supported languages by simply applying different offset values, eliminating the need to write and maintain separate code paths for each language and significantly improving programming efficiency
Data Source
AI summary
A system and method which provides simultaneous display of characters on one or more display monitors in multiple languages. The languages can include icon based languages such as Chinese and Japanese or can be traditional character based languages such as romance and Germanic languages. The system includes a main unit having a first memory in which the first memory includes character data stored in a plurality of languages. A portion of the character data in a first language corresponds to another portion of the character data in a second language, the portion of the character data in the first language and the portion of the character data in the second language are stored in the first memory at memory locations having an offset value from each other.
