Caller Video Preview Automation for Video Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video call technologies lack efficient methods for automatically providing caller previews to callees, which can enhance call acceptance rates while ensuring privacy and reducing system processing resources.
Innovation Solution
Implement a system where a caller device automatically selects and transmits a caller video to a callee before call acceptance, based on context factors such as location and user consent, and applies filters like blur or hexagon mosaic to maintain privacy, allowing the callee to disable filters when appropriate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If caller video is transmitted before call acceptance, then call acceptance rate increases, but system processing resources increase
Solution Approach 1:
The patent extracts only the necessary video preview function from the complete video call setup process. Instead of establishing full video communication infrastructure before acceptance, the system transmits only a video preview portion, reducing processing overhead while maintaining the ability to improve call acceptance rates through caller identification.
Solution Approach 2:
The system applies partial action by transmitting video preview data rather than complete video call data before acceptance. This partial transmission provides sufficient information for callee decision-making without the full resource commitment of establishing complete video communication channels in advance.
2Loss of information
If caller video is transmitted before call acceptance, then caller identification improves, but privacy protection decreases
Solution Approach 1:
The system performs preliminary privacy protection actions by applying filters to the caller video before transmission. Filters such as blur effects or anonymization are applied in advance to the video preview, allowing callee to see enough to identify the caller while automatically protecting sensitive visual information from exposure.
Solution Approach 2:
The patent applies local quality modification by selectively filtering specific portions of the caller video while maintaining other areas visible. This allows differential privacy protection where certain regions (such as faces or identifying features) are obscured while other contextual information remains visible for caller identification.
3Extent of automation
If automated video selection is implemented, then system automation increases, but device complexity increases
Solution Approach 1:
The system implements self-service automation where the caller device automatically selects and transmits appropriate video previews without requiring manual intervention. The device autonomously manages video source selection, filter application, and transmission timing, reducing user burden while managing complexity through automated decision-making algorithms.

AI summary
Implementations relate to caller previews for video calls. In some implementations, a method includes sending, by a caller device, a call request and establishing a connection with at least one callee device, automatically determining a caller context, selecting a caller video based on the caller context, and automatically transmitting at least a portion of the caller video over the connection with the at least one callee device prior to receiving a call request acceptance from the callee device. In some implementations, a caller device sends a call request to, and determines an identifier associated with, a callee device. Based on the identifier being associated with an address book, or being in an outgoing call record, of the caller device, at least a portion of a caller video is transmitted over a connection with the callee device prior to receipt of a call request acceptance from the callee device.
