The acquisition module can simultaneously meet three acquisition modes, and the Web page end communicates with the acquisition module through a control program to issue the acquisition modes to each acquisition module so as to achieve the purpose of acquisition control.
The Web page end adds the following information acquisition pages: a single acquisition module can simultaneously support three acquisition modes, such as acquisition of a single TP, a single program and designated PID. The three processes with the same mode are that frequency point parameters are firstly set, signals are locked, programs are searched and then recorded. The three modes are mainly distinguished by different recording modes, which are respectively:
TP frequency point recording; and recording all data of the frequency point of the whole locking signal.
Recording by a specified PID: record a certain type of data (e.g., if video pid of program of cctv-1 is 32, then i can record only cctv-1 video).
Program recording: as a set of several pids (a program contains several pids such as video pids, audio pids, subtitle pids and pids of program information).
