Recall and Triggering System for On-Air Content Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Television networks face challenges in adding content and graphics to programming after it has been provided to affiliated stations, as existing protocols do not allow for efficient insertion of local content into video signals in real-time or file-based systems.
Innovation Solution
A recall and triggering system that uses standard protocols like SCTE 104 and SMPTE for inserting commands into video signals, allowing television networks to transmit video with embedded commands to affiliated stations, which then detect and insert local data, such as graphics and content elements, into the video using cloud/server data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard protocols are used for video signal transmission, then compatibility and ease of operation are improved, but the ability to insert local content and graphics after video provision is lost
Solution Approach 1:
The system embeds recall commands and triggering data into the video signal during initial encoding at the television network, before transmission to affiliated stations. This preliminary embedding of control information allows remote stations to dynamically insert local content without requiring post-transmission protocol modifications or complex real-time communication infrastructure.
2Productivity
If video signals are transmitted to affiliated stations before adding local content, then production workflow is simplified, but real-time content insertion capability is reduced
Solution Approach 1:
The patent uses an intermediary data structure (recall commands embedded in video signals) that enables asynchronous content insertion. The affiliated station's processor acts as an intermediary that detects these embedded commands and automatically retrieves local content from cloud/server databases, eliminating the need for real-time manual coordination between network and station producers while maintaining topical relevance.
3Device complexity
If existing protocol systems are used, then infrastructure complexity is minimized, but functionality for adding content after video provision is limited
Solution Approach 1:
The system makes the existing video signal transmission infrastructure multi-functional by embedding recall commands and triggering data within standard video protocols. This allows the same transmission infrastructure to simultaneously perform its traditional function of delivering video content while also carrying control information for dynamic local content insertion, eliminating the need for separate communication channels or protocol modifications.

AI summary
There is provided a recall and triggering system and method for the control of on-air graphics at remote locations. The system including a television network and an affiliated station, the television network configured to insert a command into a video and transmit the video including the command to the affiliated station, and the affiliated station configured to receive the video including the command from the television network, store the video in the memory, detect the command from the video stored in the memory, retrieve the data from a database based on the command, modify the video using the data to generate a modified video, and transmit the modified video to a display device. The database may be stored in the memory of the affiliated station or on a separate server. The data may include graphics, content, databases, spreadsheets, tables, websites, news, or other graphical content.
