Problems solved by technology

Because the prompt voice of an audio and video dynamic menu item generally only has a few words, the audio playback time is very short, and the video and audio are switched at the same time, which will make the user feel that the screen is constantly switching and flickering
However, if the video and audio are not switched at the same time, the audio cannot objectively reflect the content of the current video and cannot meet the requirements of users.

Embodiment Construction

[0024] The embodiment of the present invention is a method for playing a dynamic audio and video menu, which is used to dynamically play more than two audio and video menu items. The specific process includes:

[0025] Firstly, the acquired audio and video data in the two or more audio and video menu items are respectively decomposed into one channel of audio data and one channel of video data. Such as figure 1 As shown, each optional audio and video menu item includes video data (such as a video prompt file) and audio data (such as an audio prompt file). Wherein, the corresponding audio and video menu items may be ordinary files containing audio and video encoding, such as files in encoding formats such as MPEG-4 and H.264. At the same time, the decomposed one-way audio data and one-way video data can also be stored in corresponding storage devices respectively.

[0026] Secondly, at least two channels of video data corresponding to each audio and video menu item obtained ...

Abstract

The present invention provides a playing method of dynamic audio video menu and its realizing device, for dynamically play more than two audio video menu items, in particular decomposing each audio video data of acquired at least two audio video menu single item into one audio data and one video data, and save the video datas; integrating at least two video data corresponding to each audio menu single item obtained by decomposition to a same video streaming data; transmitting the audio data and integrated video streaming data to the terminal, and playing in the terminal. The video streaming data of each menu item in the dynamic audio video menu is smoothly played, and voice prompt is spliced seamless, the effect of audio dynamic menu achieves identical effect of playing single audio file, completely free from user listening.

Description

technical field [0001] The present invention relates to the field of interactive audio and video technologies, in particular to a method and device for playing a dynamic audio and video menu. Background technique [0002] In daily life, people often use IVR (Interactive Voice Response, interactive voice response) service and IVVR (Interactive Voice & Video Response, interactive voice and video response) service, wherein, IVVR can also be called video IVR, or Called "Video Portal (video portal)" etc., described IVVR business is based on the video call to realize the voice and video interaction between the two ends, and its application environment is specifically: one end is a user, and the other end (central office) is Applications (i.e. application systems). [0003] In the IVR service, in order to adapt to the constantly updated service content, the audio dynamic menu function is usually used. The audio dynamic menu creation process is that each optional audio dynamic menu...
