Problems solved by technology
At present, there is no subjective quality evaluation device that can be effectively applied to IPTV in the market, and it is impossible to evaluate the video quality based on human vision at the IPTV terminal. Therefore, the QoE applied to IPTV has serious defects, which poses a threat to the further development of IPTV. and promote barriers

The invention relates to a device for estimating the quality of experience (QoE) for an internet protocol television (IPTV) user, comprising a network transmission detection module, a video coding detection module and a comprehensive analysis module, wherein the network transmission detection module is connected with the comprehensive analysis module by the video coding detection module and provided with a video streaming input end. The invention also provides a method for estimating the QoE for an IPTV user, which is realized based on the device. In the method, after the network transmission detection module acquires video streaming, the network transmission detection module detects the video streaming to acquire network transmission influence parameters; then the video coding detection module detects the video streaming to acquire video coding influence parameters; and finally the comprehensive analysis module calculates the sensory mean opinion score (MOS) of the user in accordance with the network transmission influence parameters and the video coding influence parameters so as to realize the estimation for subjective video quality. The device and method provided by the invention can be used to effectively improve the QoE of the existing IPTV.
Description
technical field [0001] The present invention relates to the field of network technology, in particular to the field of Internet TV technology, and specifically refers to an IPTV user experience quality evaluation device and evaluation method. Background technique [0002] Quality of service (quality of service, QoS) requirements and related QoS guarantee technologies are proposed in many telecommunication services. In the ITU-T E.800 standard, QoS is defined as "the comprehensive effect of service performance that reflects the user's satisfaction with business use." For traditional telecommunication services, QoS usually refers to network performance, especially network transmission performance. [0003] Since IPTV is an upper-layer application service in the telecommunication service, traditional QoS cannot satisfy the evaluation of end-user experience. Therefore, the industry often uses quality of experience (QoE) to describe the service quality for end-user applications....
