Embodiment Construction

[0033] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0034] figure 1 Shown is the method that the present invention realizes PIP in IPTV, comprises:

[0035] 101: Configure the channel numbers of the common channel and the PIP channel in the SMS (channel processing module), save the media stream of the PIP channel and the media stream of the common channel in the media server, and configure the playback of the PIP channel and the common channel in the EPG server address;

[0036] For a certain IPTV channel, its common channel number plus a weight can be used as the PIP channel number. For example, if the common channel number of IPTV channel CCTV1 is 1, its PIP channel number can be configured as 1+1000=1001.

[0037] Since the PIP channel is displayed in a small window, a compression method different from that of the common source file of the IPTV channel can be adopted, and the audio part can be remov...

Abstract

The invention discloses a method for realizing picture-in-picture in an IPTV, comprising the following steps: when playing a common channel of the IPTV, a set-top box (STB) opens a picture-in-picture (PIP) window after receiving a command for playing a PIP channel; the STB acquires a playing address of the PIP channel from an electronic program guide (EPG) server and acquires media stream of the PIP channel from a media server according to the playing address of the PIP channel; and the STB plays the media stream of the PIP channel acquired from the media server in the PIP window. By realizing the PIP function in the IPTV, the invention leads IPTV users to freely switch and preview other video programs in the situation of not withdrawing from the video program which is viewed, thus bringing brand-new experience for the users.

Description

technical field [0001] The invention relates to the technical field of IPTV (Internet Television), in particular to a method, system and set-top box for realizing picture-in-picture in IPTV.
