Embodiment Construction
[0031] see figure 1 , a volume adjustment system 100 based on the RF4CE (Radio Frequency for Consumer Electronics, radio frequency for consumer electronics) protocol, including a set-top box 20, a playback device 30 and a remote control 40, wherein the playback device 30 includes but is not limited to a television (TV) , DVD player, speakers, etc. The communication between the STB 20 and the playback device 30 and between the STB 20 and the remote controller 40 is performed through the RF4CE protocol. The remote controller 40 sends a remote control signal to the set-top box 20 through the RF4CE protocol. Wherein, the panel of the remote controller 40 is provided with a plurality of control buttons, such as a volume up button, a volume down button, etc., and the remote controller 40 generates a corresponding remote control signal to the set-top box 20 in response to the operation of the control buttons by the user. The playing device 30 will be described below by taking a TV ...

The invention discloses a volume regulation method, which is applied to a volume regulation system comprising a set-top box, a playing device and a remote controller. A volume regulation sequence table for defining corresponding relationships between volume state combinations of the set-top box and the playing device under volume increasing and decreasing regulation and regulation objects is stored in the set-top box. The method comprises the following steps of transmitting a volume regulation control signal by using the remote controller; sensing the output volumes of the set-top box and the playing device according to the signal by using the set-top box; if the signal is a volume increasing control signal, determining a volume regulation object according to the corresponding relationships between the volume state combinations and the volume regulation objects under the volume increasing regulation; otherwise determining the volume regulation object according to the corresponding relationships between the volume state combinations and the volume regulation objects under volume decreasing regulation; increasing or decreasing the volume of the determined volume regulation object. According to the volume regulation method, the volumes of the set-top box and the playing device are regulated through the set-top box in a staggered way, subtle volume change experiences are provided for a user.
Description
technical field [0001] The invention relates to a volume control system, in particular to a set-top box and a volume adjustment method. Background technique [0002] With the rapid development of digital TV, set-top boxes (Set Top Box, STB for short) have entered thousands of households. Due to the front-end modulation of the TV signal, the volume of each program will be different. When watching TV programs, the user frequently adjusts the volume of the TV set because some volumes are too loud or too low. At present, although the remote control keys for controlling the TV set and the set-top box are concentrated on a learning remote control, these keys are still in charge of each, that is, the learning type remote control controls the TV set and the set-top box separately. There is no integrated remote control effect. If the volume of the set-top box has been adjusted to the minimum volume sometimes, because there is no audio source input in the volume amplifier of the TV...
