Digital Device Cross-TV Playback Continuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in continuing to watch specific content on one TV from a specific timing point on another TV, and in synchronizing settings across multiple TVs, as they need to manually remember and adjust settings and playback information.
Innovation Solution
A digital device that connects to TVs, receives play information and setting data, saves this information, and allows control of another TV to resume playback and adjust settings automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually controls a 2nd TV to play content in continuation with a specific timing point, then the content playback can be continued, but the user must memorize the specific timing point which increases operation complexity
Solution Approach 1:
The patent applies the copying principle by transmitting playback position information from the first TV to the digital device, which then copies and stores this information. When the user selects content on the digital device, the playback position information is automatically transmitted to the second TV, eliminating the need for manual memorization of timing points.
Solution Approach 2:
The digital device serves as an intermediary between the first TV and the second TV. It receives playback position information from the first TV, stores it, and automatically transmits it to the second TV when needed, thereby mediating the information transfer and eliminating manual intervention.
2Ease of operation
If a user manually changes setting values for each TV, then the settings can be adjusted, but the user must memorize setting values which increases operation complexity and time consumption
Solution Approach 1:
The patent applies the copying principle by receiving setting values from the first TV, storing them in the digital device's memory, and automatically transmitting these copied settings to the second TV. This eliminates the need for manual memorization and repeated adjustment of setting values across multiple devices.
Solution Approach 2:
The patent implements preliminary action by pre-storing setting values in the digital device's memory before they are needed. When the user wants to control the second TV, the settings are already prepared and can be automatically transmitted, saving time that would otherwise be spent on manual adjustment.
3Ease of operation
If play information is transmitted from 1st TV to digital device and then to 2nd TV, then seamless playback continuation is achieved, but communication and data transmission complexity increases
Solution Approach 1:
The digital device performs multiple functions: it acts as a remote controller for TV control, a memory device for storing playback position information and setting values, and a communication hub for transmitting data between devices. This multi-functionality consolidates complexity into a single universal device rather than requiring complex integration between TVs.

AI summary
Disclosed are a digital device and controlling method thereof. The present invention includes a display unit, a communication unit connecting a communication with a 1st external device, the communication unit receiving a play information of at least one content played in the 1st external device from the 1st external device, a memory storing the play information of the at least one content received from the 1st external device and a controller configured to control the communication unit to connect a communication with a 2nd external device, control the display unit to display at least one indicator corresponding to each of the at least one content on a screen based on the play information of the at least one content, and control the communication unit to transmit a control signal for playing a specific content corresponding to the 1st indicator and a play information of the specific content to the 2nd external device in response to a 1st command for selecting a 1st indicator from the at least one indicator.
