[0027] Example 1

[0028] Regarding the problem 1 that needs to be solved above: traditional video conferencing equipment is often bulky, expensive, and requires dedicated meeting rooms and a complex installation and debugging process, which to some extent limits the popularization and application of video conferencing.

[0029] The solution is as follows: A video conferencing set-top box that can be connected to a TV in this embodiment includes a housing 100 and a mounting base 200.

[0030] The housing 100 houses the main control module. Near the center of the rear side wall of the housing 100 are an HDMI port 110 and an AV port 120. On the left side of the rear side wall of the housing 100 are two USB 3.0 ports 130. Two first microphones 140 are symmetrically arranged on the front side wall of the housing 100. A display screen 150 is mounted in the center of the front side wall of the housing 100. The two first microphones 140 are symmetrically arranged on the front side wall of the housing 100 with the display screen 150 as the center. A second microphone 160 is located at the bottom of the housing 100. A mounting bracket 200 is mounted on the top of the housing 100. A camera 210 is mounted at the front end of the mounting bracket 200, and a third microphone 220 is mounted at the rear end of the mounting bracket 200. The dimensions of the housing 100 are ≤150×100×30mm. The HDMI port 110 and AV port 120 are compatible with different TV models. USB 3.0 ports are also included. Interface 130 supports external HD cameras: 1080P / 60fps. The housing 100 has a built-in array microphone: two first microphones 140, two second microphones 160 and three third microphones 220 in a circular layout, with a signal-to-noise ratio ≥70dB. The main control module adopts a quad-core ARM processor: CPU+GPU+NPU heterogeneous architecture, which dynamically switches H.264 / H.265 encoding strategies according to network bandwidth. Not shown in the figure, the housing 100 also integrates a network module. The two first microphones 140, two second microphones 160 and three third microphones 220 form an audio processing module, which integrates the AEC echo cancellation algorithm. The main control module is pre-installed with an embedded Linux system, which automatically matches the TV resolution upon startup: supports 4K adaptation. The network module supports hot switching between dual-band WiFi 2.4G / 5G and Gigabit Ethernet.

[0031] Compared to traditional dedicated video conferencing equipment, this device reduces hardware costs by more than 60% and saves on investment in dedicated display equipment. It features video latency of ≤200ms, an audio sampling rate of 48kHz, support for background noise suppression, and the ability to expand peripherals such as document scanners via USB interface. It also supports integration with smart home systems, such as automatically adjusting indoor lighting in meeting mode.

[0032] The main control module uses the Rockchip RK3399 chipset and integrates:

[0033] Video encoding: Supports H.265 4K@30fps hardware encoding;

[0034] Network transmission: QoS is guaranteed through RTP / RTCP protocol;

[0035] Audio processing: 3A algorithms based on the WebRTC open-source framework: AEC / ANS / AGC;

[0036] The HDMI interface 110 and AV interface 120 are equipped with an adaptive EDID controller, which automatically recognizes the TV resolution 720P / 1080P / 4K and adjusts the output format to avoid overscanning issues.

[0037] The power interface 170 is located on the right side of the rear wall of the housing 100. A switch 180 is located on the rear wall of the housing 100 between the HDMI interface 110 and the USB 3.0 interface 130. The power interface 170 is connected to the power module. The power module adopts a wide voltage design: input 100-240VAC, built-in overvoltage / overcurrent protection circuit, and is compatible with multiple international power standards.

[0038] Example 2

[0039] Regarding the second problem to be solved above: most existing set-top boxes require screws for installation, which takes a long time and is cumbersome, making subsequent disassembly and maintenance inconvenient.

[0040] The solution is as follows: A video conferencing set-top box that can be connected to a TV in this embodiment also includes a clamping component 300.

[0041] The clamping assembly 300 includes a fixed plate 310 detachably connected to the center of the bottom of the housing 100 and a clamping plate 320 located at the bottom of the fixed plate 310. The tail end of the clamping plate 320 is hinged to the tail end of the fixed plate 310. A torsion spring is connected to the hinge point between the clamping plate 320 and the fixed plate 310. Anti-slip pads 330 are installed at corresponding positions on the top of the clamping plate 320 and the bottom of the fixed plate 310. Four suction cups 190 are symmetrically installed on the bottom of the housing 100 with the clamping plate 320 as the center. By pressing the clamping plate 320, the clamping plate 320 is flipped open and the torsion spring is squeezed, allowing the housing 100 to be moved until the desired position is reached. The fixed position is located between the fixing plate 310 and the clamping plate 320. When the clamping plate 320 is released, the torsion spring rebounds and pushes the clamping plate 320 to flip and reset. The clamping plate 320 and the fixing plate 310 clamp the position that needs to be fixed, such as the edge of the table or other protruding parts. The anti-slip pad 330 can increase the friction between the fixing surface and the fixing surface, and can quickly clamp and fix the housing 100. Furthermore, by disassembling the fixing plate 310, the fixing plate 310 can be separated from the bottom of the housing 100. When the housing 100 is placed on a horizontal surface, the suction cup 190 is attracted to the surface, which allows the housing 100 to be placed horizontally for use.

[0042] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
