Camera Encoding Preconfiguration for Transcoding-Free Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording systems in enterprise networks face resource-intensive transcoding demands due to inconsistent video quality requirements from playback devices, which is resource-intensive and inefficient, and this can lead to resource wastage on the video recorder, which can be addressed by predicting and adapting encoding parameters based on usage patterns, content detection, and access control events to avoid unnecessary transcoding.
Innovation Solution
A video recorder system that selects encoding parameters based on usage patterns, detected content, and access control events to capture and store multiple video streams at different qualities, allowing direct playback without needing transcoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the video recorder receives high quality video streams from cameras and transcodes them to requested encoding formats, then video quality requirements from multiple playback devices can be met, but resource consumption and processing time increase due to transcoding operations
Solution Approach 1:
The video recorder predicts future video stream requests by analyzing usage patterns, detected content, and access control events. Based on these predictions, the system proactively configures cameras to capture and transmit video streams at the anticipated encoding parameters before the actual playback request occurs. This eliminates the need for real-time transcoding when the playback device requests the video stream.
Solution Approach 2:
The system dynamically adjusts camera encoding parameters (such as resolution, frame rate, and bitrate) based on predicted playback requirements. By changing the encoding parameters at the source before transmission, the video recorder avoids resource-intensive transcoding operations while still meeting the specific quality requirements of different playback devices.
2Productivity
If the video recorder stores multiple video streams at different encoding qualities, then direct playback without transcoding is enabled, but storage space requirements increase
Solution Approach 1:
Instead of pre-storing multiple video streams at different qualities, the system predicts the specific encoding parameters needed for future playback requests and configures the camera to generate only those specific streams. This approach maintains playback efficiency by having the correct quality stream ready while avoiding the storage overhead of maintaining multiple versions of all video content.
3Manufacturing precision
If the camera captures video at the highest quality supported, then video quality is maximized, but network bandwidth and processing resources are wasted when lower quality is sufficient
Solution Approach 1:
The system dynamically adjusts the camera's video capture parameters (resolution, frame rate, bitrate) based on predicted playback device requirements. By matching the capture quality to the actual needs of the playback device, the system maximizes video quality when high quality is needed while conserving network bandwidth and processing resources when lower quality suffices, eliminating the waste of capturing at maximum quality for all scenarios.

AI summary
Systems and methods are disclosed for preparing encoded video streams at a video recorder. One or more encoding parameter values for capturing the video using the camera can be selected, based at least in part on one or more of a usage pattern of requesting video from a camera or a detected content of a video from the camera or an access control event in an area associated with the camera. The camera can be configured to provide a video stream using the one or more encoding parameter values, and the video stream encoded based on the one or more encoding parameter values can be received from the camera.
