Baidu Shadow Stick 3S Appearance
1, size.
The outer box of Baidu's 3S is a 179x127x63mm small box that looks small, but its weight is 650 grams, which shows its real material.
2, parameter configuration.
Baidu Shadow Stick 3S uses the Cortex-A9 architecture's Jing Chen 2.0 GHz quad-core processor, Mali-450 eight-core graphics processor, 1GB DDR memory, 8GB MLC storage space, 4K and Dolby support, and the supported protocols include DLNA/ AirPlay. The hardware parameters are the mainstream configurations of various box products currently on the market, but since there is no 4K TV this time, the 4K playback function cannot be tested.
3, video content.
From the perspective of packaging, Baidu's 3S is a product that supports Mango's Internet TV, that is, it integrates the high-quality mass content of Mango TV, the largest entertainment TV platform in mainland China, and officially claims that there are 1 million hours of built-in TV. Various types of program content.
4, accessories.
Open the box, there are Baidu shadow stick 3S TV box, remote control, HDMI cable, power adapter and instructions. According to the instructions, Baidu Shadow Stick 3S is a product manufactured by Skyworth, a well-known household electrical appliance manufacturer in China. It is black and has a matte finish on the surface. It does not collect fingerprints.
5, interface and OEM.
Baidu shadow stick 3S on the back of the HDMI interface, cable port, USB port and 5V power adapter port, the back of a rubber pad, easy to place, the middle of the front is Baidu's Logo. The design of 3S is very delicate and beautiful. Because it is a large-scale OEM, the mold and manufacturing process are also perfect. Placing it on the living room TV cabinet is a pleasing artwork.
Baidu shadow stick 3S use articles
1, the application store.
Baidu Shadow Stick 3S application is not much inside, but fortunately the Baidu Shadow Stick 3S supports external USB installation files, so do not worry.
2, Mango TV authorization.
Baidu Shadow Stick 3S Focus: Mango TV. Due to the licensing relationship, TV sets authorized by Mango TV have not been approved. After that, it may not be possible to watch Hunan Satellite TV's variety shows and stand-alone broadcasts.
Mango TV is actually an embedded application, which includes carousels, movies, TV series, variety shows, animation, music, MV, documentary, lifestyle, microfilm, 1080P area, Dolby area, and so on. There are a wide variety of programs and a rich source of programs, including TVB's drama series in Hong Kong and Huayi Brothers' movies.
In fact, the TV box is the most important content of the program. Due to the ban of the SARFT, many Internet video applications are no longer available on the TV box. The Baidu film stick 3S solved the problem of genuine program sources through cooperation with Mango TV. Therefore, Baidu's 3S is reassuring.
3, local play.
Baidu Shadow Stick 3S also supports external USB devices for local playback. Since the TV does not support 4K, 4K playback is not tested this time. However, depending on its hardware configuration, playing 4K is not a problem.
On-Grid Inverter converts DC power to AC power for feeding back to the grid. The frequency of the output voltage of the grid-connected inverter needs to be the same as the grid frequency (50 or 60Hz), which is generally achieved by the oscillator in the machine, and the output voltage will also be limited not to exceed the grid voltage. Modern high-quality grid-connected inverters can have an output power factor of 1, which means that the output voltage and current phases are the same, and the phase difference between them and the grid voltage is within 1 degree. There is a microprocessor in the inverter that can sense the AC waveform of the grid, and according to this waveform, generate voltage and send it back to the grid. However, the electricity sent back to the grid needs to have a certain proportion of reactive power, so that the power of the nearby grid is within the allowable limit. noon) its voltage may rise too high.
If the power of the grid is cut off, the grid-connected inverter needs to be disconnected from the grid quickly. This is a regulation of the National Electrical Code (NEC) in the United States to ensure that when the grid is out of power, the grid-connected inverter will not provide power to the grid, and at this time the workers who maintain the grid will not be electrocuted.
Properly configured, grid-tie inverters allow a home to use alternative energy sources that it generates itself (such as solar or wind power) without cumbersome wiring and without the need for batteries. If there is insufficient alternative energy, the insufficient part will still be provided by electricity from the grid.
Grid-connected inverters are widely used in household photovoltaic power generation systems, commercial and industrial photovoltaic power plants and other scenarios. By connecting to the grid, they help to achieve efficient use of renewable energy and reduce carbon emissions, promoting sustainable development and popularization of clean energy.
