Unicast Session Manager for Subscriber Consent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable TV networks lack a reliable and simple means to transmit user-uploaded or web-based content to individual subscribers while ensuring subscriber consent, particularly for advertising content.
Innovation Solution
A system that initiates a unicast session with an end-user device over a dedicated channel, transmits an identification unicast multimedia stream to provide a recognizable service identifier, and receives a content transmission command to deliver multimedia content in response, ensuring human authorization through mechanisms like CAPTCHA to prevent computerized deciphering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable TV networks use traditional broadcast infrastructure, then content transmission coverage is wide, but there is no reliable means to ensure subscriber consent and personalize content transmission
Solution Approach 1:
The patent segments the content transmission process into distinct phases: identification phase (transmitting identification unicast multimedia stream to obtain service identifier), authorization phase (receiving content transmission command with service identifier), and content delivery phase (transmitting content multimedia stream). This segmentation enables reliable subscriber consent assurance through structured interaction while maintaining system manageability.
Solution Approach 2:
The patent introduces a service identifier as an intermediary element that mediates between the content transmission system and the subscriber. The service identifier, obtained through the identification unicast multimedia stream, serves as a unique authorization token that ensures subscriber consent before content delivery, resolving the contradiction between reliability and complexity.
2Adaptability or versatility
If dedicated unicast channels are established for each subscriber, then personalized content transmission is enabled, but network bandwidth consumption increases
Solution Approach 1:
The patent implements dynamic channel allocation where unicast channels are established only when needed for personalized content transmission. The system transitions between broadcast and unicast modes based on subscriber requests and content type, enabling personalized delivery without continuously consuming dedicated bandwidth for all subscribers.
Solution Approach 2:
The identification unicast multimedia stream is transmitted preliminarily before actual content delivery to obtain the service identifier. This preliminary action establishes the authorization framework without immediately consuming bandwidth for content transmission, as the actual content delivery only occurs after successful authorization.
3Reliability
If complex authentication mechanisms are implemented, then subscriber consent can be ensured, but the transmission process becomes more complicated
Solution Approach 1:
The patent extracts the authentication mechanism into a separate identification unicast multimedia stream that is transmitted independently from the main content delivery process. This extraction allows the authorization function to be isolated and simplified, with the service identifier serving as a concise authorization token that doesn't complicate the overall transmission process.
Solution Approach 2:
The patent changes the parameter representation from complex authentication data to a simplified service identifier. By transforming the authentication mechanism into a compact identifier format, the system maintains reliable authorization while significantly simplifying the transmission process and reducing the complexity of handling authentication information.

AI summary
This disclosure provides systems and methods for transmitting content to users. In some implementations, a system can include a session manager operable to initiate a unicast session with an end user device over a dedicated channel and to transmit a unicast multimedia stream associated with the unicast session. The unicast multimedia stream can include service identifier that is recognizable to the end user. The system can also include an interface operable to receive a transmission command that includes the end-user recognizable service identifier, and to transmit the content associated with the multimedia stream to the end user device in response to the content transmission command.
