AV Device Automatic OSD Synchronization via HDMI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional AV systems require manual OSD display setting for each individual device, making it impossible to automatically reflect settings across multiple connected AV devices, especially when OSD settings differ between TV and external AV devices.
Innovation Solution
An AV device with a connection portion for external AV devices, an OSD display portion, a display setting portion, a setting data generation portion, and a setting data transmission portion that generates and transmits OSD display setting data to connected AV devices, allowing for automatic synchronization of OSD settings across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual OSD display setting is performed for each individual AV device, then each device can have its own customized settings, but it requires switching input for each device and performing separate setting operations, increasing operation time and complexity
Solution Approach 1:
The patent merges the OSD display setting operations for multiple AV devices into a single unified setting process. By combining the setting functions of the TV and external AV devices, the system allows users to perform OSD display settings for all connected devices simultaneously through one operation, eliminating the need to switch inputs and perform separate settings for each device.
Solution Approach 2:
The patent implements a universal setting mechanism that can apply OSD display settings across multiple types of AV devices (TV, external devices) through a single interface. The setting operation performed on the TV is universally applied to all connected external AV devices, making the setting function multi-functional and device-agnostic.
2Adaptability or versatility
If manual OSD display setting is performed by switching input for each device, then individual device settings can be adjusted, but the operation complexity increases and it becomes difficult to track which device is being configured
Solution Approach 1:
The patent combines multiple device setting operations into a single unified interface. Instead of requiring users to switch between different input sources and perform separate settings for each device, the system merges all OSD display settings into one operation that simultaneously configures the TV and all connected external AV devices.
Solution Approach 2:
The patent introduces the TV as an intermediary device that mediates the setting operation between the user and multiple external AV devices. The user performs the setting operation on the TV, which then acts as a mediator to automatically transmit and apply the same settings to all connected external devices, simplifying the operation while maintaining individual device configurability.
3Stability of the object's composition
If OSD display settings are made common across TV and external AV devices, then consistency is improved, but when direct opposite settings are needed, separate configuration is required for each device
Solution Approach 1:
The patent implements a dynamic setting system that can adaptively switch between common and individualized configurations. The system initially applies common OSD display settings to all devices for consistency, but allows users to easily modify individual device settings when needed, with changes automatically updated only for the specific device without affecting other devices.
Solution Approach 2:
The patent segments the setting management into two independent layers: a common setting layer that applies to all devices for consistency, and an individual device setting layer that allows device-specific customization. This segmentation enables users to manage common settings once and then make targeted individual adjustments without affecting the overall system consistency.

AI summary
An AV device is provided that can automatically perform OSD display setting of other AV devices at a time based on local ODS display setting even when a plurality of AV devices are connected. The AV device (depicted as TV 1) includes a connection means (depicted as an HDMI connector 21 and an HDMI connector 22) for making connection with external AV devices 3 and 4 capable of performing OSD display, an OSD processing portion 23 for performing OSD display on a display 17, and a system controller 20 for controlling the entire system. The OSD processing portion 23 generates ODS display setting data 23a from the display setting such as a character color and size in OSD display received from a user using a TV remote controller 2 or the like and stores it. The system controller 20 transmits the OSD display setting data 23a for the TV 1 stored here to the external AV devices 3 and 4 via the HDMI connectors 21 and 22.
