Broadcast Control Data Segmentation for Personalized Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast techniques are inefficient in delivering personalized content to television viewers due to bandwidth limitations and user experience issues, as they either waste bandwidth or require cumbersome viewer interactions to receive personalized content.
Innovation Solution
A method and system that generate and transmit control data indicative of a receiver-accessible source of personalized content, inserting it into multiple control streams accessible in different operational states, allowing seamless delivery of personalized content without disrupting regular channel viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personalized content is broadcast on every channel of every transponder frequency, then all viewers can receive personalized content regardless of their current channel, but bandwidth is severely wasted
Solution Approach 1:
The patent segments the delivery of personalized content by separating control data transmission from content delivery. Control data is inserted into multiple control streams across different transponder frequencies, while the actual personalized content is delivered through a designated data stream. This segmentation allows receivers to obtain control information without requiring all transponders to carry full personalized content, thereby reducing bandwidth waste while maintaining ease of access.
Solution Approach 2:
The patent introduces control data as an intermediary element that mediates between the broadcast system and personalized content delivery. The control data contains information about where and how to access personalized content, acting as a pointer or reference that enables viewers to receive personalized content without requiring every transponder to carry the actual content data. This intermediary approach resolves the contradiction by enabling access while conserving bandwidth.
2Loss of energy
If personalized content is delivered on a unique channel of a single transponder frequency, then bandwidth is saved, but viewers must tune their receivers to the correct channel in synchronization with content arrival
Solution Approach 1:
The patent applies preliminary action by inserting control data into control streams that are accessible across multiple transponder frequencies before the actual personalized content is delivered. The control data is prepared in advance and placed in streams that receivers can access regardless of which transponder frequency they are currently tuned to. This preliminary placement of control information eliminates the need for viewers to manually tune to specific channels or synchronize with content arrival times.
Solution Approach 2:
The patent makes the control data transmission universal by distributing it across multiple control streams on different transponder frequencies. This multi-functional approach ensures that regardless of which transponder a receiver is accessing, the control data for personalized content delivery is available. This universality resolves the contradiction by maintaining bandwidth efficiency while eliminating the need for complex viewer tuning operations.
3Productivity
If the amount of personalized content or number of recipients increases, then more personalized content can be delivered, but bandwidth scarcity becomes a serious obstacle
Solution Approach 1:
The patent transitions from a single-dimension bandwidth constraint to a multi-dimensional solution by utilizing multiple transponder frequencies and control streams simultaneously. Instead of increasing bandwidth on a single channel, the system distributes control data across multiple frequency dimensions. This dimensional expansion allows the system to serve more recipients and deliver more personalized content without proportionally increasing the bandwidth burden on any single resource.
Solution Approach 2:
The patent segments personalized content delivery across multiple control streams and transponder frequencies rather than consolidating it on a single channel. This segmentation allows the system to scale to more recipients and more content by distributing the load across multiple dimensions of the broadcast infrastructure, thereby increasing productivity without creating a proportional bottleneck in bandwidth availability.
Data Source
AI summary
A method, system and apparatus for conveying personalized content to a viewer associated with a receiver are disclosed. In some embodiments, the method comprises generating control data indicative of a receiver-accessible source of personalized content for the viewer and inserting the control data into a plurality of control streams for transmission to the receiver, each of the control streams being accessible to the receiver when in a different respective operational state.
