Digital Radio Broadcast Large Object Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital radio broadcasting systems face challenges in efficiently transmitting large data objects due to the non-deterministic nature of radio propagation, which often results in corrupted or lost headers, leading to lengthy delays in decoding.
Innovation Solution
The method involves segmenting large objects into fragments, generating long and short messages with headers containing unique identifiers and object descriptions, and communicating these messages to a digital radio broadcast transmitter, allowing for partial assembly of objects without waiting for the entire header, and repeating transmissions to ensure receipt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional digital radio broadcasting systems transmit large data objects with complete headers before data, then transmission reliability is maintained, but decoding delays increase significantly due to header corruption or loss in non-deterministic radio propagation
Solution Approach 1:
The patent segments large data objects into smaller fragments and transmits them in multiple packets. Each packet contains a portion of the data object along with associated header information. This segmentation allows the receiver to begin decoding data as it arrives in subsequent packets without waiting for the complete header and entire data object to be received, thereby reducing decoding delays while maintaining transmission reliability through progressive data reconstruction
Solution Approach 2:
The patent transmits header information and initial data fragments in advance within early packets. The receiver is prepared to begin decoding operations as soon as sufficient data is received, rather than waiting for complete header verification. This preliminary action enables the system to start processing data before the entire transmission is complete, reducing overall decoding time while maintaining reliability through error checking on received portions
2Loss of information
If large data objects are transmitted as complete units with full headers, then data integrity is ensured, but bandwidth efficiency decreases due to repeated header transmissions and inability to process partial data
Solution Approach 1:
The patent divides large data objects into multiple smaller fragments that can be transmitted across different packets. Each fragment is accompanied by necessary header information for independent decoding. This segmentation improves bandwidth efficiency by allowing parallel transmission and progressive decoding of data portions, while data integrity is maintained through error checking and verification of received fragments
Solution Approach 2:
The patent enables the receiver to perform partial decoding operations on received data fragments without requiring complete reception of the entire data object. The system processes available data incrementally as it arrives, improving bandwidth efficiency by utilizing transmitted data before the complete transmission is finished, while still ensuring data integrity through verification of decoded portions

AI summary
Methods and systems for transmitting and receiving large objects via digital radio broadcast involve retrieving an object and an object description; assigning a unique identifier to the object; segmenting the object into a plurality of fragments; generating at least one long message having selected ones of the fragments and a long header including the unique identifier and the object description; generating at least one short message having selected ones of the fragments and a short header including the unique identifier; and communicating the at least the long message or the short message to a digital radio broadcast transmitter. In accordance with certain embodiments, reassembly of the object can begin with either a long message or a short message.
