Device and method for inserting and controlling advertisements in audio/video playing

Abstract

The invention discloses a device for interring and cutting as well as controlling advertisements in audio-video play and a method thereof. Besides a stream media service module, the device also comprises a playing-controlling management backstage, a playing-controlling service module, a playing-controlling interface; wherein, the playing-controlling management backstage is used for monitoring and controlling source devices and the playing-controlling module is used for keeping communication which the playing-controlling management backstage through the playing-controlling interface. The playing-controlling service module also comprises: a list-updating submodule, a service-guarding submodule and a communication-managing submodule. The method includes the steps: when obtaining a playing strategy list from the playing-controlling management backstage, the playing-controlling module automatically analyzes the strategy list, searches for the content played currently and calculates time length which has been played; then, the playing-controlling module generates a playing list file with a suffix of wsx of a server terminal and begins to play the content at this moment. Base on WMS9 technology, the method for interring and cutting as well as controlling the advertisements in the audio-video play and the method thereof maintain the interring-cutting and playing time of the advertisements, thus realizing the audio-video play with relatively high implementation efficiency, relatively good reliability and flexible playing strategy.

Description

technical field [0001] The invention relates to computer software, multimedia technology and audio and video playback technology, in particular to a device for inserting and controlling advertisements in audio and video playback based on Windows Media Service9 technology. The invention also relates to an implementation method applied to the device. Background technique [0002] At present, the development of multimedia technology and Internet technology has promoted the improvement of people's demand for network streaming media, especially the presentation of complex audio and video content. Internet content operators (SP) often publish a series of organized audio and video program content through the Internet in real time according to certain playback rules. management system to support. The audio and video playback and advertisement insertion control method based on Windows Media Service9 (hereinafter referred to as WMS9) satisfies the pre-scheduled management of Windows...

AI Technical Summary

Problems solved by technology

[0011] But the existing network streaming media broadcast control system has the following defects: 1, the efficiency is low

Due to its real-time re-encoding feature, the demand for device resources is high, and it is impossible to output multiple audio and video streams on a single device under the premise of ensuring playback control requirements

2. Restricted playback strategy

There are currently similar solutions, but there is no comprehensive broadcast strategy control capability. The pre-broadcasted programs can only be broadcast in the relevant order, which cannot meet the needs of scheduled advertisement insertion and temporary content playback adjustment.

3. Poor reliability

Real-time re-encoding cannot guarantee that the program will be interrupted due to a fatal error during the encoding process. Once the playback control is interrupted, the system will restart the source output manually or automatically, resulting in the timeliness of the source output cannot be guaranteed.
