| 发明名称 | Video recording method and video recording device | ||
| 摘要 | A video recording method is provided. The method includes steps of: determining a threshold bit rate according to a storage space and an expected recording period; capturing a video data; determining whether a current bit rate is greater than the threshold bit rate; storing a predictive frame of the video data when the current bit rate is not greater than the threshold bit rate; and not storing the predictive frame when the current bit rate is greater than the threshold bit rate. | ||

| 主权项 | 1. A video recording method, comprising: determining a threshold bit rate according to a storage space and an expected recording period; capturing a video data; determining whether a current bit rate is greater than the threshold bit rate; when the current bit rate is not greater than the threshold bit rate, storing a predictive frame of the video data; and when the current bit rate is greater than the threshold bit rate, not storing the predictive frame; determining whether the video data is an intra frame; and when the video data is the intra frame, calculating the current bit rate according to a recorded period and a recorded data amount. | ||
