Hybrid learning is becoming one of the important applications by integrating e-learning and traditional face-to-face instruction together. The paper presents the architecture of PEHLP which can create an environment where the hybrid learning of physical education can be accomplished efficiently using the national elaborate physical education course resources. To integrate the heterogeneous learning resource of different education platforms, the learning course is logically divided into the present part and the content part and the Smart Deliverer is devised. To realize the visibly communication and intercourse during the hybrid learning process, the Video-editor is proposed. Adopting the Video-editor, the teacher can review students' action video and makes comments on the action which is wrong, and the student can find out the mistakes from his/her action video. To promote the review functioning, the algorithm for key frame extraction is proposed and the results show the algorithm is efficient.
