Remote Viewing Terminal for Shared TV Channel Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display technologies do not effectively manage scenarios where multiple users view different content on a shared display, and users may miss content when one user changes channels without consideration for others.
Innovation Solution
A terminal apparatus with remote control functionality that includes a communication unit, signal receiving unit, memory unit, and display unit, capable of transmitting commands to a video display apparatus, decoding stored content, and displaying it on a user's terminal, ensuring seamless viewing across multiple users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single video display apparatus is shared by multiple users, then device utilization is improved, but content viewing continuity deteriorates when one user changes channels
Solution Approach 1:
The system segments the viewing experience by associating each terminal apparatus with a specific user and their preferred channel. When a channel change occurs on the video display apparatus, the system detects this change and independently controls each terminal apparatus to display appropriate content (either the changed channel or the user's preferred channel), ensuring continuous viewing experience for each user segment.
Solution Approach 2:
The video display apparatus acts as an intermediary that not only displays content but also monitors channel changes and communicates this information to terminal apparatuses. This intermediary function enables the system to coordinate between the shared display and individual user terminals, maintaining viewing continuity without requiring direct user intervention.
2Ease of operation
If channel switching is allowed during CM playback, then user control flexibility is improved, but content loss increases for users who switch channels
Solution Approach 1:
The system performs preliminary detection of channel changes during CM playback. When a channel change is detected, the system proactively stores the CM content and prepares to display it on the terminal apparatus after the channel change occurs, preventing content loss before it happens rather than reacting after the fact.
Solution Approach 2:
The system creates a copy of the CM content when a channel change is detected during CM playback. This copied content is then displayed on the terminal apparatus, allowing users to view the CM content they might have missed due to channel switching, thereby preventing information loss while maintaining operational flexibility.
3Reliability
If CM content is stored and displayed after channel switching, then content completeness is improved, but device complexity increases
Solution Approach 1:
The video display apparatus performs multiple functions: it serves as the primary display device, a channel change detector, a content monitor, and a controller for terminal apparatuses. By consolidating these functions in a single device, the system achieves content completeness without proportionally increasing overall system complexity, as the video display apparatus leverages its existing capabilities for additional purposes.

AI summary
A terminal apparatus having a function of remotely controlling a video display apparatus includes a communication unit that transmits a command related to setting of the video display apparatus and receives status information, a signal receiving unit that receives a signal output from a broadcast station and decodes a video content, a memory unit that stores a content of a command including a channel of the video content, and a display unit that displays the video content and various types of information. In this terminal apparatus, the communication unit transmits an identification code specific to the terminal apparatus when transmitting the command, and when the status information is received after a channel of the video display apparatus is set by remote control, the video content of the channel stored in the memory unit is decoded by the signal receiving unit and is displayed on the display unit.
