Multimedia Device Auto-Tuning Application Information Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data broadcasting systems limit users in accessing and using applications without changing channels, as they can only verify the presence and content of applications by switching to specific channels, restricting the method of accessing data broadcasting services.
Innovation Solution
A multimedia device and method that allow users to verify the presence and content of applications without changing channels by auto-tuning through all channels, extracting information from signaling data, and providing a list of related applications for user selection and independent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users switch to specific channels to verify application presence and content, then they can access data broadcasting services, but the operation becomes complex and time-consuming due to channel switching requirements
Solution Approach 1:
The patent creates a copy of application information from multiple channels and presents it in a channel-independent guide interface. Instead of requiring users to switch channels to view application details, the system extracts application information from signaling data across channels and displays it in a unified interface, allowing users to access application content without physical channel switching.
Solution Approach 2:
The patent introduces an intermediary application guide interface that mediates between the broadcast channels and the user. This intermediary layer aggregates application information from multiple channels and presents it in a unified manner, eliminating the need for users to directly switch channels while still providing access to application content.
2Adaptability or versatility
If applications are bound to specific channels, then channel-specific content can be delivered, but user flexibility and adaptability are reduced when wanting to use applications independently of channels
Solution Approach 1:
The patent segments the relationship between channels and applications by separating application information extraction from channel switching. The system extracts application information from signaling data independently of channel changes, allowing applications to be accessed as separate entities from their original channel context. This segmentation enables users to select and use applications without being constrained by channel-bound restrictions.
3Productivity
If users access applications by switching channels, then they can use data broadcasting services, but time is lost due to the channel switching process
Solution Approach 1:
The patent performs preliminary extraction of application information from multiple channels and prepares it for display in the application guide interface. By pre-processing and organizing application information before user selection, the system eliminates the need for time-consuming channel switching during the user's application access process, significantly reducing the time required to access and use applications.

AI summary
A multimedia device and a method for controlling the same are disclosed. The multimedia device includes a receiving unit configured to receive a broadcast signal, a display unit, and a controller, wherein the controller may be configured to control the receiving unit to receive a broadcast signal through each channel available for tuning, when a first command for executing auto channel tuning is detected, to verify a presence or absence of an Application Information Table (AIT) in signaling information included in the received broadcast signal of each channel, to extract information on an application related to a specific channel from an AIT, when the AIT exists in signaling information included in a broadcast signal of the specific channel, and to store the extracted information on the application in a memory.
