Streaming Playback Automation for Synchronized AV Redistribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices struggle with synchronization issues in wireless transmission and processing of audio/video media streams due to delays, leading to unsynchronized playback on different playback devices.
Innovation Solution
A device configured with a processor and storage that executes instructions to automatically retrieve user credentials, select a web media service, log in, and initiate playback, with the ability to control the stream and send it to connected audio/video devices, using APIs and web browsers to reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio is sent to a wireless audio playback device, then audio playback is enabled on a separate device, but audio and video may not be synchronized due to delays from wireless transmission and processing
Solution Approach 1:
The patent introduces a synchronization mechanism that acts as an intermediary between the video playback and wireless audio transmission. The system sends synchronization data from the first device to the second device, which then uses this data to adjust its audio playback timing, ensuring that audio and video remain synchronized despite wireless transmission delays
Solution Approach 2:
The system implements a feedback loop where the first device receives status information from the second device regarding audio playback progress and synchronization state. Based on this feedback, the first device can adjust video playback timing or send corrective synchronization data to maintain proper audio-video alignment
2Reliability
If manual login and control processes are used for web media services, then user credentials can be verified and streams controlled, but the process is time-consuming and complex
Solution Approach 1:
The system performs preliminary actions by automatically retrieving stored user credentials before the user needs to manually log in. The processor automatically fills in username and password fields on the sign-in page, completing the authentication process without requiring the user to manually enter credentials
Solution Approach 2:
The system enables self-service automation where the device automatically manages the entire login process including credential retrieval, form filling, and submission. The user simply needs to provide a command, and the system handles all subsequent authentication steps autonomously
3Ease of operation
If automated retrieval and insertion of user credentials is implemented, then login process is simplified, but automatic web browser control is required
Solution Approach 1:
The patent employs a web driver as an intermediary software layer that sits between the automated control system and the web browser. This web driver translates high-level commands into browser-specific actions, automatically controlling the browser to navigate to sign-in pages, fill forms, and submit credentials without requiring complex direct browser manipulation

AI summary
Automated playback and redistribution of internet streaming content using a device that is configured to receive a command to select a media service, and automatically, without human intervention, retrieve user credentials for the selected media service, use the command to select a correct media service instance, retrieve a sign-in page from the selected media service, insert the user credentials into the sign-in page, log into the media service, then select a stream on the media service and initiate playback of the selected stream.
