Closed Caption Service Buffer Embedding Diagnostic Traces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closed captioning systems require a decoder to render text, and devices equipped to decode closed caption information often lack upstream diagnostic feedback, leading to limitations in content delivery and control.
Innovation Solution
The system includes a data stream with closed caption service buffers that can embed and store service traces, allowing for the selection and presentation of closed caption information and service information, enabling diagnostic feedback and improved content control through embedded service traces in the data stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If closed caption information is encoded within a video signal using conventional techniques, then text can be displayed on screen, but the text only becomes visible with the use of a decoder and devices may not provide upstream diagnostic feedback
Solution Approach 1:
The patent merges closed caption data and service trace data into a single closed caption service buffer, allowing both content information and diagnostic information to be transmitted together through the same decoding path, eliminating the need for separate diagnostic hardware
Solution Approach 2:
The closed caption service buffer is designed to serve multiple functions: it can carry both closed caption content data and service trace diagnostic data, making the same transmission buffer universal for both content delivery and diagnostic feedback purposes
2Loss of information
If service trace data is stored in a separate buffer, then diagnostic information can be maintained, but the system complexity increases and integration with content delivery becomes more difficult
Solution Approach 1:
The patent combines service trace buffer and closed caption service buffer into a single unified buffer structure, eliminating the need for separate buffer management while preserving both content and diagnostic information through selective reading
3Productivity
If closed caption buffers are used for content delivery, then content information can be transmitted, but upstream diagnostic feedback capability is lost
Solution Approach 1:
The patent segments the buffer into different readable portions: one portion for closed caption content data and another portion for service trace data. The decoder can selectively read from the appropriate segment based on the needed function, maintaining both content delivery and diagnostic capabilities
Solution Approach 2:
The closed caption service buffer is designed as a multi-functional buffer that can simultaneously serve content delivery and diagnostic feedback purposes by storing both types of data and allowing selective access to each type as needed
Data Source
AI summary
Methods and systems for providing data such as content are disclosed. A method can comprise selecting a closed caption buffer and storing a service trace in the selected closed caption buffer. The closed caption buffer comprising the stored service trace can then be activated to provide service information.
