Video Stream Resumption via DVR Buffering During WiFi Disconnects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home-based video distribution networks are not well-suited for wireless transmission of live video streams due to transient interruptions in wireless connectivity, which disrupt the user experience.
Innovation Solution
A system with a wireless access point that automatically records live video streams to a DVR during transient disruptions and resumes playback from the recorded stream upon reconnection, ensuring continuous viewing without loss of continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission of live video streams is implemented, then user convenience and mobility are improved, but connection stability and viewing continuity deteriorate due to transient interruptions
Solution Approach 1:
The system performs preliminary recording of the video stream to the DVR before a disconnect occurs. When a wireless connection interruption is detected, the already-recorded video is immediately played back from the DVR, avoiding any interruption in the user experience. This preliminary action ensures that the video content is preserved and can be resumed without gaps.
Solution Approach 2:
The DVR acts as an intermediary between the video source and the wireless client device. Instead of directly streaming video over the potentially unstable wireless connection, the system uses the DVR as a buffer and relay. The video is recorded to the DVR and then played back, with the DVR serving as a stable intermediate storage device that decouples the video delivery from the unstable wireless connection.
2Speed
If the video stream is continuously transmitted over wireless network, then real-time viewing is achieved, but transient disconnects cause interruptions and degrade user experience
Solution Approach 1:
The system ensures continuous video playback by recording the video stream to the DVR and then playing it back. Even when the wireless connection is interrupted, the video playback continues uninterrupted from the DVR. This maintains the continuity of the useful action (video viewing) despite the transient disconnect, as the video is delivered from the stable DVR rather than relying on continuous wireless transmission.
3Adaptability or versatility
If wireless client devices are integrated into the video distribution network, then device versatility and accessibility are improved, but transient WiFi disruptions cause stream interruptions
Solution Approach 1:
The DVR serves as an intermediary that stabilizes the video delivery to wireless devices. Instead of having the video source directly communicate with the unstable wireless connection, the video is recorded to the DVR and then played back. This intermediary approach allows wireless devices to be integrated into the network with improved reliability, as the video delivery is buffered and managed by the stable DVR rather than being directly dependent on wireless connection stability.

AI summary
Systems and methods executable by a home based media distribution system for preserving the continuity of a video transmission following a WiFi disconnect include transmitting a media stream via a wireless access point associated with a wireless client; receiving a disconnect report from the access point; in response to the disconnect report, diverting the media stream to a digital video recorder (DVR); receiving a reconnect report from the access point; and automatically resuming the media stream from the point when the disconnect occurred.
