Problems solved by technology
[0003] However, known video surveillance algorithms tend to be complex and require frequent deep packet inspection (DPI) of the bitstream in order to obtain the required information about the video, or they require the original video source in order to perform a comparison between the monitored video and the original video. comparison between
Due to the computing capacity that such a task would require, such a solution would not be feasible for a network monitoring detection system that must analyze thousands of sessions in parallel and in real time

Embodiment Construction
[0090] figure 1 A block diagram of a monitoring device according to one embodiment is shown. The monitoring device 101 includes a data interface 102 and a determination unit 103 . The data interface connects to the end-to-end communication path between the video server 105 and the video client 104 and is configured to capture video resolution information and retrieve client display resolution information. The determining unit 103 is configured to determine a quality measure of the video session based on the video resolution information and the client display resolution information and based on a buffer model modeling a fill level of a receive buffer in the video client 104 , the receive buffer is buffering the video file before playback. The video client 104 is implemented in a user equipment (UE), which handles the protocol stack HTTP / TCP / IP / PDCP / RLC / MAC / L1. Video server 105 is implemented at a service provider's location within the Internet and implements the protocol st...

The invention relates to a monitoring device for monitoring a video session in a data network between a video server providing a video file and a video client playing the video file, comprising: a data interface configured to connect to an end-to-end communication path between the video server and the video client and configured to capture video resolution information and to retrieve client screen resolution information; and a determination unit configured to determine a quality measure for the video session based on the video resolution information, based on the client screen resolution information and based on a buffer model, the buffer model modeling a fill level of a receive buffer in the video client, the receive buffer being configured to buffer the video file before playing the video file.
Description
technical field [0001] The invention relates to a monitoring device and method for monitoring a video session between a video server and a video client in a data network. Background technique [0002] Video streaming or progressive downloading is a common application within the Internet. Video Streaming A video streaming client, such as a mobile or stationary operator, connected via an ISP (Internet Service Provider) requests a streaming server located somewhere within the ISP network or outside the Internet to send a video stream. One protocol that may be used is HTTP over TCP / IP. As opposed to accessing a web page or traditional video downloads, a video client begins displaying the content of the requested file before the client has successfully downloaded the entire source file. The transmission of video content in an IP network is affected by the transmission characteristics of the underlying transmission network, such as bandwidth, delay, jitter, and packet loss. The...
