Identification and authentication of user profiles for digital television systems
A recently granted patent (Publication Number: US11778270B2) describes a method and system for providing personalized service data to multiple devices registered under a user profile. The method involves providing service data to a first device, which includes a first identifier of a content source accessed via the user profile registered with both the first and second devices. The second device, with which the user profile is registered, sends a second identifier of a second content source accessed for at least a threshold time. The service data is then updated to include the second identifier and sent back to the first device.
Based on the updated service data, the first device can update its interactive interface to include selectable elements corresponding to the first and second content sources accessed via the user profile. This allows for a personalized and tailored user experience on the first device.
The method also includes receiving a channel change command by the second device and determining that the second content source was accessed for at least the threshold time in response to the command. This ensures that the service data accurately reflects the user's content preferences.
The patent also covers scenarios where there are multiple user profiles registered with both the first and second devices. In such cases, the service data can be specific to each user profile, and the method includes sending second service data corresponding to a second user profile registered with the first device. This allows for personalized content recommendations and preferences for each user.
Additionally, the method includes detecting a request to login with a different user profile at the first device and sending the corresponding service data in response to the request. This ensures that the correct service data is provided when switching between user profiles.
The patent also covers authentication and identification processes. The method involves receiving identification data from the first device and comparing it with authentication data corresponding to multiple user profiles. The user profile is identified based on the matching identification data. In cases where the identification data is invalid, the first device is prompted to create a new user profile.
Overall, this patent describes a method and system for providing personalized service data across multiple devices registered under a user profile. It enables a seamless and tailored user experience by updating service data based on content accessed by different devices and user profiles.
