Abstract
This set-top box (SB) communicates with the video server (VS). SB consists of the user port (UP), the broadcast group administrating module (BGA), the decoding module (DE), the TV signal testing module (TST), the timing module (TM) and the feedback signal generating module (FSG). UP receives the user info (UI). BGA adds SB into the broadcast group (BG) according to UI. DE decodes codes according to the BG residing SB. TST tests whether SB receiving the TV signal. TM counts time according to the preset timing period and generates interruption instruction (II) while time exceeded. FSG generates a feedback signal (FS) depending on II and sends FS to VS. This SB and the FS generating method use timer to generate FS and sends FS back to VS. This makes the service supplier using flexibly the FS to meet user's various requirements.
