Time-Synchronized Data Request for High-Speed Frame Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home network technologies lack an efficient apparatus and method for data requesting and obtaining, particularly for devices like TVs that output many image frames per second, making it difficult to accurately search for desired data using only time information.
Innovation Solution
A data requesting method and apparatus that includes a time information-generating unit, a request command-generating unit, and a transmitter to create and send data request commands synchronized with the data obtaining apparatus, allowing for accurate data retrieval by searching stored data or requesting from an external server based on time information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a data obtaining apparatus outputs sixty (60) image frames per second, then the output speed is improved, but it becomes difficult to accurately search for the desired data by only using time information
Solution Approach 1:
The patent introduces a new dimension for data identification by capturing an image of the displayed content. Instead of relying solely on time information (one dimension), the system uses image recognition to identify the specific frame being displayed (adding a visual dimension). This allows accurate retrieval of the desired data even when the apparatus outputs 60 frames per second, as the captured image serves as a unique identifier for the specific moment's content.
2Device complexity
If only time information is used for data retrieval, then the device complexity is reduced, but the data search accuracy deteriorates
Solution Approach 1:
The patent introduces an image capture device as an intermediary between the data obtaining apparatus and the retrieval system. The captured image acts as a mediator that bridges the gap between simple time-based requests and accurate content identification. This intermediary approach maintains relative simplicity while dramatically improving search accuracy, as the image serves as a direct visual reference to the desired content.
3Measurement precision
If an image pickup unit is added to capture displayed content, then the data retrieval accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by using the image pickup unit for multiple purposes: capturing the displayed content for identification, verifying the current frame, and potentially other diagnostic functions. This universal approach justifies the added complexity, as a single component serves multiple roles in improving data retrieval accuracy rather than requiring separate specialized devices for each function.

AI summary
Disclosed herein are methods and apparatuses for requesting and obtaining data, in which time information is generated by use of a first device, and a data request command requesting data output by a second device is generated at a time point indicated by the time information. The generated data request command is transmitted, wherein the data request command includes the time information.
