Event Data Transmission via Bandwidth Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting event data, such as live sports or entertainment events, face inefficiencies in bandwidth utilization, especially when additional information like odds or supplemental data requires preparation or post-processing, and when events overlap or have gaps, leading to high transmission costs and suboptimal use of high-bandwidth channels.
Innovation Solution
The method involves splitting event data into different groups and transmitting them over channels with varying bandwidths, with high-bandwidth channels used for image and sound data and lower-bandwidth channels for supplemental data, allowing for parallel or offset transmission of supplemental information, and using a time control apparatus to manage the sequence and timing of events to maximize bandwidth utilization.

Engineering Contradiction Analysis
1Manufacturing precision
If high-bandwidth transmission channels are leased for live event transmission, then image and sound quality can be maintained at high resolution, but transmission costs increase significantly
Solution Approach 1:
The patent segments event data into different categories: live image sequences requiring high bandwidth, supplemental data requiring preparation time, and post-event data. By transmitting only the essential live video feed over the expensive high-bandwidth satellite channel while sending supplemental and post-event data through alternative lower-cost channels, the system maintains high image quality while reducing transmission costs.
2Loss of information
If supplemental event data requiring preparation or post-processing are transmitted over high-bandwidth channels, then complete information can be delivered, but bandwidth utilization becomes inefficient
Solution Approach 1:
The patent divides data transmission into separate channels based on data type and timing requirements. Live image sequences are transmitted over satellite channels during events, while supplemental data (odds, statistics) and post-event information are transmitted through terrestrial or internet channels, maximizing the utilization of expensive satellite bandwidth for time-critical visual content only.
Solution Approach 2:
The system transmits supplemental data such as odds and statistics before events occur or during gaps between events through lower-bandwidth channels, allowing preparation and processing to occur offline. This ensures complete information delivery without occupying high-bandwidth satellite channels during these preparation phases.
3Manufacturing precision
If transmission channels are kept free for preparation and post-processing of supplemental data, then data quality can be maintained, but bandwidth utilization decreases during gap periods
Solution Approach 1:
The patent implements periodic transmission of supplemental data during gap periods between events. When no live event is being transmitted, the system utilizes the available satellite bandwidth to send batches of supplemental information (odds updates, statistics, previews) that require preparation time, thereby maintaining data quality while improving overall bandwidth utilization during otherwise idle periods.
4Productivity
If events are transmitted with overlapping time schedules, then more content can be delivered, but bandwidth conflicts occur requiring channel reservation
Solution Approach 1:
The patent resolves bandwidth conflicts from overlapping events by adding temporal and channel dimensions to the transmission strategy. Different event data types are transmitted at different times (live during events, supplemental during gaps) and through different channels (satellite for live video, terrestrial/internet for supplemental data), allowing multiple events to be supported without direct bandwidth conflicts.

AI summary
The present invention relates to a method and an apparatus for transmitting event data to a display device, wherein both image sequences for displaying images of an event and supplemental data for the display of additional information relating to the event are transmitted as event data by a transmission device to the named display device. The event data are split and are transmitted over a plurality of transmission channels of differing bandwidth, with at least some of the image sequences being transmitted over at least one transmission channel of higher bandwidth and at least some of the supplemental data being transmitted over at least one transmission channel of lower bandwidth.
