Communication Device Playback Control via Source Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices lack appropriate control over content playback when receiving new playback requests, often interrupting ongoing content or failing to switch between content streams due to inadequate identification of source devices or users.
Innovation Solution
Incorporating a receiving unit for playback requests, an obtaining unit for device/user identification information, and a control unit that determines whether to start or continue playback based on the identity of the source devices/users, ensuring seamless transitions or maintaining current playback when requests are from the same or different entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the communication device determines to play back the second content without considering the source device or user identity, then the playback request is processed quickly, but the first content playback is interrupted unnecessarily and user convenience deteriorates
Solution Approach 1:
The patent introduces identification parameters (source device ID and user ID) to the playback decision-making process. The control unit changes its behavior based on these parameters by determining whether the source device or user is identical between the first and second playback requests, thereby resolving the contradiction between processing speed and user convenience through parameter-based differentiation.
2Stability of the object's composition
If the communication device determines not to playback the second content without considering source device or user identity, then the first content playback continues uninterrupted, but the user cannot switch content and convenience deteriorates
Solution Approach 1:
The control unit utilizes source device identification and user identification parameters to make intelligent playback decisions. When the parameters indicate the same source device and user, the system allows content switching while maintaining playback stability for different sources, thus resolving the contradiction between playback continuity and content switching capability.
3Device complexity
If the communication device uses simple playback request handling without source/user identification, then the device complexity is low, but the playback control precision and user experience are insufficient
Solution Approach 1:
The patent enhances playback control precision by introducing identification parameters (source device ID and user ID) into the control mechanism. The control unit processes these parameters to determine appropriate playback actions, thereby improving measurement precision of playback control without significantly increasing device complexity through structured parameter handling.

AI summary
In a case where a communication device receives a playback request for second content while playing back first content, the communication device starts playing back the second content, based on a fact that a communication device identified by identification information about a communication device that has transmitted a playback request for the first content is identical to a communication device identified by identification information about a communication device that has transmitted the playback request for the second content, and continues playing back the first content, based on a fact that the communication devices are different. The communication device starts playing back the second content, based on a fact that a user identified by user identification information about the first content is identical to a user identified by user identification information about the second content, and continues playing back the first content, based on a fact that the users are different.
