Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 Shown, the computing method of IPTV set-top box VMOS value of the present invention specifically comprises the steps:

[0021] S1. During playback, the playback terminal of the IPTV set-top box receives RTP packets from the streaming media server, and each RTP packet consists of an RTP packet header and 1 to 7 TS packets. In a calculation cycle, record the number of TS (Transport Stream, transport stream) packets actually received from the streaming media server, that is, the number of TS packets=the data length / 188 bytes received in a calculation cycle (TS packet length ).

[0022] Before the playback terminal of the IPTV set-top box is playing, the playback terminal can establish a connection with the quality management platform as required, obtain the video quality monitoring threshold value (3.6 in this embodiment...

Abstract

A calculating method of an IPTV set top box VMOS value relates to the IPTV set top box technology field. The method comprises the steps that a play terminal of an IPTV set top box receives an RTP packet of a streaming media server during a play process, the RTP packet comprises a TS packet, in one calculating period, the number of the actually-received TS packets is recorded and the number of the TS packets which should be received is calculated; a packet loss probability of one calculating period is calculated; network jitters of all the RTP packets in one calculating period are calculated; the play terminal calculates an influence factor of the packet loss probability to a VMOS, calculates an influence factor of the network jitters to the VMOS and acquires the VMOS value through a formula which is VMOS=5-f(drop)-g(jitter). By using the method, a calculation amount of the VMOS value is reduced and the current VMOS value is rapidly calculated. The method is suitable for a present network environment.

Description

technical field [0001] The invention relates to the technical field of IPTV set-top boxes, in particular to a method for calculating the VMOS (Mean Opinion Score for Video, video quality average subjective opinion score) value of an IPTV set-top box. Background technique [0002] As an interactive video service bearing mode, IPTV (Interactive Internet Television) has changed the traditional way of watching TV. With the network as the transmission channel and the set-top box as the terminal, it provides users with various interactive services including on-demand, live broadcast, and time-shifting. Video programs and value-added services. When implementing IPTV services, operators will set different access methods for users according to the local network structure and user scale, and establish an end-to-end service channel between the platform and users to carry video services. Through authentication and authentication on the service platform, the IPTV set-top box interacts w...
