Recording method, entity and system for media stream

Abstract

The invention relates to the field of communication and discloses a method, an entity and a system for recording a media stream so as to ensure that a network television video can be more efficiently and flexibly recorded. In the invention, a PVR support entity at a network side firstly judges whether the property of the media stream to be recorded is matched with a recording property configured by a customer, if so, the media stream is directly recorded into a network storage space, otherwise, the media stream is recorded into the network storage space after being converted according to the recording property configured by the customer; wherein, the conversion can be the conversion between media formats, the intra-format conversion such as the conversion of bit rate, the conversion of frame rate, the conversion of image resolution ratio and the conversion of the number of color channels, etc., and can also be the intelligent conversion such as the extraction and the recording of the key frame of a scene, the extraction and the recording of an intra-frame coding frame, the extraction and the recording of classified scenes and the extraction and the recording of the relevant scenes of specific figures, etc. The PVR support entity at the network side can be positioned in an internetworking functional entity or a media processing functional entity.
