## Background
TECHNICAL FIELD
The present disclosure relates to the field of mobile terminal techniques, and in particular to a method for audio-video re-matching of TV programs on a mobile terminal, and a mobile terminal.
BACKGROUND
With the development of science and technology, a television (TV) service has been extensively applied in various electronic products. In recent years, a television service on a mobile terminal, such as China Mobile Multimedia Broadcasting (CMMB), Digital Video Broadcasting-Handheld (DVB-H), Satellite Digital Multimedia Broadcasting (S-DMB), has become a new selling point of the mobile terminal gradually. The popularity of the television service on a mobile terminal mainly comes from the fact that a user may be freed from various restrictions of a traditional television by watching a television program such as one on sports, entertainment, news, and the like conveniently with a mobile terminal.
When a user watches a television program on a mobile terminal, a network platform will provide complete information on an audio and a video of the TV program. However, sometimes the user desires to receive only information on the video (or audio) of one program, and to receive at the same time information on the audio (or video) of another program. For example, when watching a sports program, the user may desire to watch only scenes of a great game, and at the same time to listen to an audio from a music channel. With existing techniques, a program can only be muted, and can not be matched with any other audio by incorporating an audio from another program.
The existing techniques also provide a solution of embedded displaying, wherein complete information on the audio and video of a program is presented in a primary displaying area of a mobile terminal, and the video of another program is shown in a secondary displaying area; although the solution may provide multiple programs for a user at the same time, it cannot re-match a current program with a new audio/video. In addition, the solution requires use of two modulators and two demodulators, and applies only to a mobile terminal with a large screen, thereby causing a problem such as high cost, difficulty in popularization.

A mobile terminal with a type of television service “DVB-H” acquires the target information called for by the user from the network platform by
sending the network platform a calling request calling for a target channel corresponding to the address of the target information;
receiving an encrypted program stream corresponding to the target channel and a copyright object corresponding to the encrypted program stream sent by the network platform after the network platform receives the calling request;
acquiring the target information called for by the user by decrypting the encrypted program stream using the copyright object.
In the step S104, after outputting the target audio included in the target information and the video of the current program respectively to the corresponding local playing module(s) so as to be played, the mobile terminal may also locally save the the target audio and the video of the current program being played as a custom program according to user requirement.
Step S105, otherwise the mobile terminal stops playing the video of the current program, acquires target information called for by the user, and outputs a target video in the target information and the audio of the current program respectively to the corresponding local playing module so as to be played;
In the step S105, after outputting the target video included in the target information and the audio of the current program respectively to the corresponding local playing module(s) so as to be played, the mobile terminal may also locally save the target video and the audio of the current program being played as a custom program according to user requirement.
Step S106, the user sends the mobile terminal a request for resuming playing the current program;
When the user needs to resume the original audio and video of the current program, the user may send the request for resuming playing the current program to the mobile terminal.
Step S107, the mobile terminal stops calling for the target audio/video called for by the user, and outputs the audio and video of the current program respectively to the corresponding local playing module(s) so as to be played.
Step S108, when the user ends the television program application on the mobile terminal, the mobile terminal stops playing the television program.
