Embodiment

[0029] see figure 1 , the invention discloses a method for acquiring multimedia push content based on ultrasound, which comprises the following steps:

[0030] S1. Pre-generate a push tag corresponding to the push content, convert the push tag into an ultrasonic signal by means of ultrasonic coding, and then superimpose the code stream with the multimedia file to synthesize multimedia data containing the ultrasonic signal. The push content is one or more of video, audio, text, image and web page.

[0031] S2. The multimedia terminal plays multimedia data containing ultrasonic signals. At this time, the push tag is played along with the multimedia content in the form of ultrasonic waves. Since ultrasonic waves cannot be heard by human ears, users will not receive additional audio-visual interference when enjoying multimedia content. . The multimedia terminal may be a multimedia playback device such as a TV or a computer.

[0032] S3. When the user is interested in the playin...

Abstract

The invention discloses a multimedia push content acquisition method based on ultrasonic. The method comprises the following steps: pre-generating a push label corresponding to push contents, converting the push label into an ultrasonic signal, and synthesizing multimedia data containing the ultrasonic signal; playing the multimedia data containing the ultrasonic signal by a multimedia terminal; when a user is interested in the played multimedia contents of a certain node, receiving the ultrasonic signal played by the multimedia terminal at the node by using a mobile terminal; and decoding the ultrasonic signal by the mobile terminal, generating a corresponding push label again, and displaying the corresponding push contents to the user according to the push label. According to the method disclosed by the invention, the label information of the push contents is converted into the ultrasonic form to be played with the multimedia contents, the user can select the play information needing to be received according to personal preference and interests, and when the multimedia contents are played, the multimedia contents will not influence the play effect or the audio-visual experience of the user.

Description

technical field [0001] The invention relates to the field of multimedia technologies, in particular to an ultrasonic-based method for acquiring multimedia push content. Background technique [0002] At present, when playing multimedia content, most advertisements, short messages and other push information are directly inserted into the multimedia content, directly displayed or broadcast on the multimedia terminal, and passively received by consumers. These push services take up too much time or space for playing multimedia content, which not only affects the playback effect of multimedia content, but also affects the user's audio-visual experience. Users cannot selectively receive push services according to their personal preferences. Contents of the invention [0003] The purpose of the present invention is to provide an ultrasound-based multimedia push content acquisition method.
