Embodiment 1

[0036] An embodiment of the present invention provides a method for processing packet loss during video transmission, which is applied on the side of the video receiving end, such as figure 1 As shown, the method specifically includes:

[0037] Step S101, detecting whether packet loss occurs in the data packet of the currently received video frame, and when packet loss occurs, stop video decoding and notify the video sending end to perform video update;

[0038] In this step, the mode of detecting whether packet loss occurs in the data packet of the currently received video frame includes but is not limited to:

[0039] Detect the sequence number of the data packet of the currently received video frame, if the sequence number of the previously received and currently received data packet is not continuous, it is determined that packet loss occurs, otherwise no packet loss occurs.

[0040] Further, in this step, preferably, the data packet of the video frame in which the packet...

Embodiment 2

[0046] An embodiment of the present invention provides a method for processing packet loss during video transmission, which is applied on the side of the video sending end, such as figure 2 As shown, the method specifically includes:

[0047] Step S201, sending video frames to the video receiving end in the form of data packets;

[0048] Step S202, when receiving the video update notification sent by the video receiving end, based on the current video image, reorganize the frame, and use the reorganized video frame as the updated video frame, and send it to the video receiving end in the form of data packets .

[0049] In this step, reframing based on the current video image specifically includes: taking the current video image as a starting point for reframing to generate key frames and reference frames. That is to say, after reframing, the video stream resumes continuous from a key frame.

[0050] The method described in this embodiment provides key technical support for...

Embodiment 3

[0052]An embodiment of the present invention provides a method for processing packet loss during video transmission, which describes the implementation process of the present invention in detail by giving a specific example, so as to better support the solutions described in Embodiments 1 and 2. It should be noted that the technical details disclosed in this embodiment are used to explain the present invention, and are not used to limit the present invention exclusively.

[0053] In this embodiment, the RTP protocol is used to transmit the video stream between the video sending end and the video receiving end, and each RTP data packet has a serial number of the current packet, and the serial number is incremented according to the sending order of the packets.

[0054] Such as image 3 As shown, the method described in this embodiment includes the following steps:

[0055] Step S301, the video sending end sends video frames to the video receiving end according to the RTP proto...

Abstract

The invention discloses a packet loss processing method, a packet loss processing device and packet loss processing system of a video transmission process. The method comprises the following steps: detecting whether a data packet of a video frame has packet loss, the video frame is received at present, if having packet loss, stopping video decoding and informing a video sending end for performing a video updating operation; detecting whether the updated video frame sent by the video sending end is received, and decoding the updated video frame after receiving the updated video frame. According to the technical scheme, the decoding process is stopped immediately while the packet loss is detected for some video frame, the image flower screen phenomenon is avoided, the video sending end is informed for updating the video and the Caton time is reduced to the minimum. The video playing efficiency and the user experience are improved by adopting the method.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for processing packet loss during video transmission. Background technique [0002] With the continuous development of the Internet, people hope to transmit more multimedia information on the Internet. The transmission of video signals is the core of multimedia information transmission. In the process of video transmission, especially in the process of wireless data transmission, data packet loss often occurs, which will cause image blurring, freeze and other phenomena, which greatly affect the user's perception. Therefore, how to provide a solution that can avoid blurry screens and minimize stuck phenomena when data packet loss occurs has become a technical problem to be solved by the present invention. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a method, device and...
