Stream Portion Presentation Management via Background Channel Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern broadcast systems face challenges in managing stream portions, such as advertisements, which require separate auxiliary channels for transmission and can lead to inefficient resource allocation and user channel changes during presentations.
Innovation Solution
A system and method for managing stream portions by retrieving high-priority portions from a background channel, storing them in memory, and controlling their presentation to ensure desired duration and efficiency, using lists with priority values and markers for seamless integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stream portions are transmitted over separate auxiliary channels, then they can be retrieved and presented, but device complexity and resource management difficulty increase
Solution Approach 1:
The patent extracts the stream portion retrieval function from the auxiliary channel transmission mechanism and implements it through a background channel with marker-based triggering. This eliminates the need for separate auxiliary channels while maintaining reliable stream portion retrieval, thereby reducing device complexity without sacrificing reliability.
Solution Approach 2:
The background channel serves multiple functions: it transmits stream portions, carries markers for triggering, and enables efficient resource management. This multi-functional approach replaces the dedicated auxiliary channel system, reducing overall system complexity while maintaining retrieval reliability.
2Adaptability or versatility
If multiple auxiliary channels are used for stream portions, then comprehensive coverage is achieved, but bandwidth and memory resources are inefficiently allocated
Solution Approach 1:
The patent merges the stream portion transmission function with the background channel infrastructure. By combining stream portion delivery with existing background channel resources, the system achieves comprehensive stream portion coverage without requiring additional dedicated auxiliary channels, thereby optimizing bandwidth and memory resource allocation.
Solution Approach 2:
The system retrieves and stores high-priority stream portions in memory beforehand based on priority lists. This preliminary action enables efficient resource management by pre-loading only necessary stream portions, reducing real-time bandwidth requirements and memory usage while maintaining comprehensive coverage capability.
3Ease of operation
If channel changes are allowed during stream portions, then user freedom is maintained, but valuable viewing time is lost
Solution Approach 1:
The patent applies preliminary anti-action by blocking channel changes during stream portion presentation. This preventive measure stops users from changing channels while stream portions are playing, thereby preventing viewing time loss. The system maintains user freedom by allowing channel changes only when appropriate (e.g., after stream portions complete), balancing ease of operation with time efficiency.

AI summary
A method of selectively decrypting encrypted data may include selecting a plurality of encrypted data bits between and including a first encrypted data bit and a last encrypted data bit; for each encrypted data bit from the plurality of encrypted data bits: determining a corresponding encrypted block and a block number that contains the encrypted data bit, determining a corresponding counter for the determined block number, determining a bit position of the encrypted data bit within the determined encrypted block, selecting a counter bit at the bit position within the counter, encrypting the counter, and executing an XOR operation between the encrypted data bit and the corresponding encrypted counter bit.
