Downstream write operation frame:
Header code: 7乙 66 99 5一個
同步: 55
Write operation frame: 33

1. Write frequency and bandwidth command 03 80, the data length is 3 位元組. The first two bytes are the frequency points, and the 3rd bytes is the bandwidth.
   The frequency unit is MHz and retains one decimal place, 例如 474.0 兆赫, which is 12 84 (hexadecimal, decimal data is 4740). Bandwidth data 00, 01, 02 represent 6M, 7中號, 8M respectively
2. Other remote control commands (including all remote control commands such as volume addition, subtraction, 記錄, and stop)
   01FF: The data length is 1 位元組, which is the client code of the remote control code value.
   例如, the volume adds (音量+) is 4D, and the volume subtraction (音量-) 是 05.

Ending E7
例如:
1. Set frequency 666MHz bandwidth 6M
Need to send data 7E 66 99 5一個 55 33 03 80 1一個 04 00 E7
2 set frequency 474MHz bandwidth 8M
Need to send data 7E 66 99 5一個 55 33 03 80 12 84 02 E7

Need to send data 7E 66 99 5一個 55 33 01 FF 4D E7

Explanation:
1, In addition to the data segment, which can be modified, the other head and tail synchronization data do not modify, 否則, it can not respond to commands. The correct response will return data segment 00 FF, the error will return 11 10
2, modify the frequency and bandwidth, please write three bytes at the same time, the separation has not been tested.
3, Please refer to the remote control user code for the remote control code.
4, The above data are all hexadecimal.
Downstream read operation frame:
Currently only tested read frequency and bandwidth
Send the command 7E 66 99 5一個 55 11 03 80 E7
Return data 7E 66 99 5一個 55 77 03 80 12 D4 02 E7 (red is frequency point and bandwidth 482.0M 8M)

常問問題

Q: Will this tuner module work in a Samsung dvd-vr470m?

一個: This DVB-T / DVB-T2 module is only suitable for secondary development by engineers or R&D companies.

Q: Does this DVB-T receiver decode BISS codes?

一個: 沒有. The most function DVB-T / DVB-T2 H264 265 decoder is used for digital TV receivers and COFDM wireless video decoders. Any special function should contact us to verify or further development.

Q: Does this DVB-T receiver decode support ASI output?

1. The demodulation chip on our demodulation module uses a parallel interface called TSI (it has many more data lines than the ASI interface)
2. The demodulation module itself does not have an MCU and cannot be provided to customers alone. It needs to be used on our decoding board.
3. 例如, with our decoding board, we convert the signal from the TSI interface of the demodulation module into a network port signal (例如, 我們的 one-way COFDM transparent transmission does this)

Q: Please check my module with missing SMD parts, Can you tell me the type/value of these three Rs and Cs?

Q: Is the MPEG-TS output of this diversity RF DVB-T DVB-T2 module a serial or parallel interface?

一個: Our Sony EW300 chip module only has a serial TS stream in hardware.

DiBcom module is a parallel TS stream.

The parallel one is the old chip, and the current chips basically support serial and parallel. Most chips now use serial TS stream because they are directly compatible with SPI.

Supported TS stream output formats: TS serial, SPI (奴隸),SDIO (奴隸).

The above can be compatible with a set of data lines. It is convenient to use. 這樣, it is not limited to the TS stream interface, and the other two interfaces can also be used, and there are more compatible decoding chips.

The EW300 chip is currently used, but Sony has stopped production. We are going to replace it with a new chip with the same function.

Q: Your decoder chip provides video output through the standard module. How do I obtain the MPEG-TS output?

一個: Please remove the resistor in the red box in the picture below. The resistance of the resistor is 22 歐姆, and you can add it to restore the HDMI / CVBS video decoding output.

Q: Is there an AFS function on your in-car mobile tuner?

一個: 沒有. The AFS function on an in-car mobile DVB-T2 (數位視訊廣播 – 第二代地面) system typically stands for Automatic Frequency Switching or a similar feature. Its purpose is to ensure seamless reception of TV signals while the vehicle is in motion by automatically switching to the strongest available frequency of the same broadcast.

這是它的工作原理:

1. Signal Scanning: The system continuously scans for DVB-T2 signals while you are traveling.
2. Seamless Handoff: When the current frequency becomes weak due to movement, the AFS feature identifies a stronger frequency carrying the same channel and switches to it without manual intervention.
3. Improved Experience: This ensures uninterrupted viewing of TV programs, especially useful when traveling across regions with varying signal strengths.

Q: Does the system allow me to specify a frequency for searching manually? I wish to look for frequencies in steps of 1Mhz.

一個: 支援. In the below picture you can see that there is an underline at 774. You can enter different frequencies through the remote control, such as 688Mhz, 689Mhz, 690Mhz.
