Definitions
- the present invention relates to the field of communications technologies, and in particular, to a video recording method and system.
- Video recording is an indispensable feature in current networking protocols (IP), and its video communication standards are diverse.
- the current video communication standard mainly uses two types of parameter sets: Sequence Parameter Set (SPS) and Picture Parameter Set (PPS).
- SPS Sequence Parameter Set
- PPS Picture Parameter Set
- the methods of transmitting parameter sets mainly include in-band transmission and out-of-band transmission.
- the out-of-band transmission is performed by using SPS and PPS binary coding (BASE64 coding) to generate a network identification parameter set field (Sprop-Parameter-Sets, SPPS) for transmission by out-of-band signaling.
- SPS and PPS binary coding BASE64 coding
- SPPS network identification parameter set field
- This method sends the parameter set information and the media stream separately, ensuring that the parameter set information can be sent to the decoder in time, but the disadvantage of this method is: in the process of network transmission, because the device is compatible Problems such as sex may cause SPPS information to be filtered by intermediate network elements, making information transmission incomplete.
- In-band transmission is the process of encapsulating SPS and PPS information in a specific unit along with the media stream.
- the decoder can decode the video stream by parsing these specific units to obtain decoded information.
- this method guarantees the reliability of the parameter set transmission, but the disadvantages of this method are: 1) Since the parameter set information is extracted from the media stream, each specific unit must be judged and processed. Slow speed; 2) If the time margin of the decoder is insufficient, it will cause loss of video information.
