Reproduction Path Information for Selective Image Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording and reproducing apparatuses are not user-friendly when transmitting image data through communication channels, as they lack the ability to efficiently specify which parts of the image data to transmit, leading to inefficient storage and re-transmission processes.
Innovation Solution
A recording/reproducing apparatus with a recording/reproducing circuit, transmitting circuit, and control circuit that records and reproduces image data based on reproduction path information, allowing users to select and transmit specific image data according to predefined play lists, which include transmission event information, destination information, and signal format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data is stored as transmitted to enable re-transmission and different address transmission, then transmission flexibility is improved, but storage consumption increases significantly
Solution Approach 1:
The patent extracts only the necessary transmission path information (play list) from the complete image data, storing just the reproduction path instructions rather than duplicate image data. This allows the system to retrieve and transmit specific image portions on demand without consuming storage space for redundant copies of the actual image content.
Solution Approach 2:
The system pre-organizes image data into a play list structure that defines reproduction paths before transmission is needed. This preliminary organization allows the apparatus to quickly retrieve and transmit specific image portions without needing to store multiple copies, as the retrieval path is already established.
2Adaptability or versatility
If all image data is stored for potential transmission to different addresses, then transmission adaptability is improved, but recording medium storage efficiency deteriorates
Solution Approach 1:
The patent segments the image data into distinct portions with associated play list entries, allowing selective transmission of only the required segments rather than the entire image dataset. This segmentation enables transmission adaptability while maintaining storage efficiency by only retaining necessary portions.
Solution Approach 2:
The play list acts as an intermediary between the stored image data and the transmission process. It mediates by providing reproduction path information that guides selective retrieval and transmission of specific image portions, eliminating the need to store all data for all potential transmission scenarios.
3Ease of operation
If reproduction path information is recorded and used for selective transmission, then user-friendliness is improved, but system complexity increases
Solution Approach 1:
The play list structure serves multiple functions: it stores reproduction path information, enables selective image retrieval, supports transmission to different addresses, and provides user-friendly selection capabilities. This multi-functionality achieves user-friendliness without proportionally increasing system complexity, as a single data structure handles multiple operations.

AI summary
Disclosed are an image recording/reproducing apparatus and a transmitting method which are user-friendly when transmitting image data recorded on a medium to an external device. Reproduction path information for transmitting image data edited by a user is recorded on the record medium. When transmitting, reproduction path information read from the recording medium is selected, the image data is reproduced according to the reproduction path information, and the reproduced data is transmitted to the external device. The reproduction path information includes transmitting event information such as the date and time of transmission, destination information, and information related to the signal format of the image data to be transmitted.
