Some time ago, Fangzheng Box F5, the first TV box product launched by Founder, attracted a lot of attention from users because of its “watching videos, 0 advertisementsâ€. I had the privilege of starting a fancy box F5 in the near future. Let's take a look at its actual performance.
[Appearance: Unlike "box" box]
The appearance of the F5's box is unique, and it is different from the flat style of the general TV box. The square box F5 uses a three-dimensional design. The whole shape is a "cuboid" (it is indeed "founder").
The color of the box is very good with the box, the overall black tone, with the orange waistline, steady yet lively, really impressive. The indicator light of the power supply is hidden behind the orange line on the front side and lights up when the power is turned on.
Founder F5's back socket configuration quite satisfactory, the power input, HDMI, cable network port, USB2.0 and AV input, can only say that just enough, but the back of the waist line at the two small forks is very cute.
However, the Founder Box F5 equipped with a remote control on the LOW somewhat, the key button is short, pressing feedback awkward and actually still infrared remote control, does not support Bluetooth. In today's era of basic Bluetooth, infrared remote control is not enough humanity.
[See video, 0 ads]
Here's a look at its flagship feature: "watch the video, 0 ads." The UI main interface adopts a horizontal design with a navigation option at the bottom. Compared to the popular waterfall flow design from top to bottom, less information is obtained, and since the search is not supported, the corresponding search will be increased. , find the steps to increase the operation. However, it is worthy of recognition that each film and television has its own background poster and it is indeed beautiful.
Opened several recent movies and television dramas, are click to play, like "Surgical Storm" "World of Warcraft" "Battle" and other movies, television shows as manufacturers do not have advertising, I specifically observed, Most of the basic sources are from Tencent video.
Not only movies and television dramas, like running men, NBA sports events, animations, etc., also have no advertisements, and the definition is basically maintained in high definition and super clear.
Founder Box F5 also has a small feature, that is, back to the main page during playback, the background will still play video, the manufacturer may want to allow the audience not to miss every exciting moment, but the main interface viewing effect is not good, benevolent see the wise see wisdom bar .
The last thing to be reminded is: I try to install third-party applications, and there will still be advertisements through the third-party software on-demand television dramas, so this Founder box F5 "0 advertising" only supports the system's own content, can not remove third-party applications advertising.
[Local play]
Usually the next high-definition movie wants to be played on a big screen, but it's found that the box or TV does not support decoding. Therefore, the video decoding capability has become one of the important indicators for everyone to consider the box.
According to the test results of "An Bunny Video Test," the Founder Box F5 does not have a format that does not support playback (only three formats are not fully supported).
However, when the author pro-tested, the movie formats such as m2ts, TP, VOB, FLV, and TS could not be decoded and played, and even some high-rate MP4 format 4K videos could not be played normally, which was worse than my psychological expectations. Large cut.
ã€summary】
In general, the performance of the Founder Box F5 is quite satisfactory, and its own video content resources do indeed have no advertisements (except third parties) as the manufacturer said.
However, many video formats do not support decoding and cannot be played. This is a big regret for this box. Users who love online chasing dramas and hate advertisements may consider choosing. If there are users who like the author and watch 4K movies locally, they must be carefully considered.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.The story of Ethernet began in the ALOHA period. The exact time was after a student named Bob Metcalfe received a bachelor's degree from the Massachusetts Institute of Technology and moved to Harvard University across the river to pursue a PhD. During his studies, he came into contact with Abramson's work, and he was very interested in it. After graduating from Harvard, he decided to stay in Hawaii for vacation before going to Xerox Palo Alto Research Center to work in order to help Abramson work. When he arrived at the Palo Alto Research Center, he saw that researchers there had designed and built machines that would later be called personal computers, but these machines were solitary; he used the knowledge he gained to help Abramson work with his colleague David Boggs designed and implemented the first local area network. The local area network uses a long thick coaxial cable and runs at a rate of 3Mbps.
They named this system Ethernet, and people once thought that electromagnetic radiation could be transmitted through it.
Shared medium
The Carrier Sense Multiple Access (CSMA/CD) technology with collision detection specifies a method for multiple computers to share a channel. This technology first appeared in the ALOHAnet developed by the University of Hawaii in the 1960s, which uses radio waves as a carrier. This method is simpler than token ring network or main control network. When a computer wants to send information, it switches between the following actions and states:
Start-If the line is idle, start the transmission, otherwise skip to step 4.
Send-If a conflict is detected, continue to send data until the min echo receive interval is reached to ensure that all other transponders and terminals detect the conflict, and then skip to step 4.
Successful transmission-report to the higher-level network protocol that the transmission was successful, and exit the transmission mode.
Line is busy-keep waiting until the line is free.
Line is idle-before reaching the maximum number of attempts, go to step 1 to try again at random intervals.
Exceeded the maximum number of transmission attempts-report the transmission failure to the higher layer network protocol, and exit the transmission mode.
Because all communication signals are transmitted on the shared line, even if the information is only sent to one of the terminals (destination), it will be sent to all computers on the line in the form of broadcast. Under normal circumstances, the network interface card will filter out the information that is not sent to itself, and will send an interrupt request to the CPU when it receives the information whose destination address is its own, unless the network card is in Promiscuous mode. This "one talk, everyone listen" characteristic is the security weakness of the shared medium Ethernet, because a node on the Ethernet can choose whether to listen to all the information transmitted on the line. Sharing cables also means sharing bandwidth, so in some cases the speed of Ethernet may be very slow, such as after a power failure, when all network terminals are restarted.
