Broadcast Service Content Identification via Virtual Channel Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the transition from existing broadcasting standards to next-generation standards, users may miss enhanced viewing experiences if they are not aware of the availability of services using the new standard, as receivers lack the ability to identify equivalent programming content across different broadcast streams.
Innovation Solution
A reception apparatus and method that determine whether services in different broadcast streams contain the same programming content by receiving and comparing service information, including identifiers, to ensure users access the more advanced version of a service, such as ATSC 3.0 over ATSC 1.0, offering improved resolutions and features like UHD and interactivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If service information includes identifiers for content identification, then the ability to identify equivalent programming content across different broadcast streams is improved, but the complexity of service information processing increases
Solution Approach 1:
The patent extracts the essential identifier information from service information to create a separate content identification mechanism. By pulling out the core identification data into a dedicated structure, the system achieves accurate content matching without requiring complex processing of entire service information sets, thus resolving the contradiction between identification accuracy and processing complexity.
Solution Approach 2:
The patent creates a universal identifier system that can identify equivalent content across different broadcast streams, standards, and service types. This multi-functional identifier approach allows a single identification mechanism to handle diverse content matching scenarios, improving accuracy while avoiding the need for multiple specialized processing systems.
2Productivity
If receivers automatically select next-generation standard services, then users benefit from enhanced viewing experience, but the ability to choose traditional services is reduced
Solution Approach 1:
The patent performs preliminary identification and comparison of service equivalence before service selection occurs. By pre-processing the content identification and equivalence determination, the system prepares recommendation data in advance, enabling automatic selection of enhanced services while still allowing users to override the recommendation if they prefer traditional services, thus balancing automation with user choice.
Solution Approach 2:
The patent implements a feedback mechanism where the system provides recommendations based on identified equivalent content and user preferences, but allows users to provide feedback on their service selections. This feedback loop enables the system to learn from user choices and adjust future recommendations, maintaining user flexibility while progressively delivering enhanced viewing experiences.

AI summary
Identification of services that carry the same or equivalent content. A reception apparatus includes circuitry configured receive first service information for a first service included in a first broadcast stream, and receive second service information for a second service included in a second broadcast stream. The first service is associated with a first virtual channel number and the second service is associated with a second virtual channel number. The circuitry is configured to determine whether the first service included in the first broadcast stream contains the same programming content as a service included in another broadcast stream based on the first service information. The first service information includes an identifier included in the second service information when the first service included in the first broadcast stream contains the same programming content as the second service included in the second broadcast stream.
