Program Reservation System Using Mapping Information for Extended Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional program reservation systems lack a standardized communication protocol for devices when instructing timer-recording or timer-reproduction of programs, leading to complexity in user interactions, especially when devices are not adapted to extended program information.
Innovation Solution
A program reservation system that includes a reservation instruction device and a reservation execution device, where the instruction device receives extended program information and transmits an extended reservation instruction, and the execution device acquires and uses mapping information to convert the instruction into a standard program reservation, allowing seamless execution regardless of device adaptation to extended program information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standardized communication protocol is implemented for device communication in program reservation systems, then device compatibility and ease of operation improve, but implementation complexity and device complexity increase
Solution Approach 1:
The patent introduces a standardized communication protocol as an intermediary layer between devices in the program reservation system. This protocol acts as a mediator that enables seamless communication and data exchange between the receiving device and recording device, regardless of their individual adaptations to extended program information. The protocol includes standardized message formats for reservation instructions, mapping information transmission, and device capability indication, thereby improving ease of operation without requiring complex custom integration between each device pair.
2Adaptability or versatility
If extended program information is transmitted to enable future program reservations, then adaptability improves, but device complexity and information processing requirements increase
Solution Approach 1:
The patent implements preliminary action by transmitting mapping information in advance that correlates extended program identifiers with standard program identifiers. This allows devices to prepare for future program reservations by storing the mapping relationships before actual reservation requests are made. The receiving device can indicate its adaptation status to extended program information in advance, and the system can pre-establish communication channels and data structures needed for handling extended program information, thereby reducing the complexity burden during actual reservation operations.
Solution Approach 2:
The patent segments the program information handling into distinct components: extended program information, mapping information, and standard program information. This segmentation allows devices to process only the portions they are adapted to handle. The mapping information serves as a bridge that connects the extended identifier system with the standard identifier system, enabling devices to work with segmented information sets rather than requiring complete processing capability for all information types, thus managing device complexity while maintaining adaptability.
3Reliability
If mapping information is transmitted between devices to convert extended program identifiers, then reliability of program reservation improves, but communication overhead and loss of time increase
Solution Approach 1:
The patent applies preliminary action by transmitting and storing mapping information in advance, before actual program reservation operations occur. The receiving device and recording device can exchange and cache the mapping relationships between extended program identifiers and standard program identifiers beforehand. This pre-loading of mapping data eliminates the need for real-time conversion during reservation execution, thereby maintaining high reliability of program reservation while minimizing communication overhead and time loss during critical operations.

AI summary
In a receiving device, a receiver receives extended program information. A user selects a program to be reserved by a selection operation using an operation input unit. An extended reservation manager causes an instruction receiver to transmit an extended reservation instruction based on an extended program identifier for identifying the selected program. In a recording device, a receiver receives program data, mapping information, and program information. The instruction receiver receives the extended reservation instruction transmitted from the receiver. An extended reservation executor acquires an extended program identifier from the received extended reservation instruction and acquires a program identifier corresponding to the extended program identifier on the basis of the mapping information, to store a program reservation on the basis of the program identifier. A program recorder/reproducer records and/or reproduces the program data in accordance with the stored program reservation. The extended reservation instruction is configured so as not to be recognized as a reservation instruction by a recording/reproducing appliance that is not adapted to the extended program information.
