How to set UDP

If you don’t modify the default setting, then you need to modify your computer ip address to 192.168.1.110.

VLC player net stream address should be udp://@:6001

On the screen, if you see U, that current DVB-T2 receiver board does not get the signal, maybe you need check the frequency. L means lock the signal.

1. Bộ thu DVB-T với thiết bị chuyên nghiệp cấp độ phát sóng ASI

2. EW300 dual tuner demodulation module technical description

Thiết bị này là một professional-grade broadcast receiver designed for robust digital television signal reception and distribution. Đây là bảng phân tích các tính năng và mục đích chính của nó:

1. DVB-T2 Decoder Receiver:

   • DVB-T2: The latest and most advanced standard for terrestrial (over-the-air) digital television broadcasting. It offers significantly higher data capacity and better resilience to interference compared to older DVB-T.

   • Decoder/Receiver: It tunes into DVB-T2 signals transmitted over the air, demodulates them, and decodes the digital streams (băng hình, âm thanh, dữ liệu) contained within the multiplex.

2. Diversity Dual RF Input:

   • Dual RF Input: Has two separate coaxial antenna input connectors.

   • Đa dạng: This is the crucial feature. Instead of just switching to the “tốt hơn” ăng-ten, true diversity receivers combine the signals from both antennas intelligently:

     • Maximal Ratio Combining (MRC): The most sophisticated method. The receiver continuously analyzes the signal quality (ví dụ., cường độ tín hiệu, Tỷ lệ tín hiệu trên tạp âm – SNR) and phase from cả hai anten. It then weights and combines the signals mathematically to maximize the overall SNR and minimize errors (BER – Tỷ lệ lỗi bit). This provides the most robust reception, especially in challenging conditions like multipath interference or mobile reception.

   • Mục đích: Dramatically improves reception reliability, especially in areas prone to signal reflections (đa đường), sự can thiệp, or when the receiver is moving (ví dụ., in a broadcast truck).

3. Outputs:

   • IP Ethernet UDP: Provides the decoded TV channels as digital streams over an Ethernet network.

     • IP (Giao thức Internet): The fundamental protocol for network communication.

     • Ethernet: The physical and data link layer standard for wired networking.

     • UDP (Giao thức gói dữ liệu người dùng): A transport protocol often used for live video/audio streaming because it’s fast and connectionless. It typically sends streams as Đa phương tiện UDP packets, allowing multiple devices on the network to efficiently receive the same stream simultaneously. This is ideal for distributing channels within a facility (headend, phòng thu, campus).

   • NHƯNG (Asynchronous Serial Interface) Đầu ra video:

     • A very common, khỏe mạnh, and simple professional broadcast video transport standard.

     • Uses a coaxial cable (typically 75-ohm BNC connector).

     • Carries a single MPEG Transport Stream (TS) containing one or more TV channels/programs.

     • Mục đích: Directly feeds into traditional broadcast equipment like encoders, multiplexers (muxes), modulators, or playout servers that expect an ASI input. Essential for integration into existing broadcast infrastructure.

What It Does & Why It’s Used:

This device is built for mission-critical reception and distribution of DVB-T2 signals:

1. Superior Reception: các Dual RF Diversity (MRC) ensures the most stable and error-free reception possible, even in difficult signal environments or on moving platforms.

2. Flexible Outputs:

   • IP/UDP Output: Enables distribution of channels over standard IP networks for modern IP-based workflows (IPTV headends, OTT contribution, monitoring systems, cloud processing, KVM extenders).

   • ASI Output: Provides compatibility with traditional broadcast SDI/HD-SDI infrastructure and equipment. Offers a simple, dedicated, and often lower-latency path.

3. Chức năng cốt lõi: Receives terrestrial DVB-T2 broadcasts, decodes the transport stream, and makes the content available simultaneously via both modern IP networking and legacy professional video interfaces.

Ứng dụng điển hình:

• Broadcast Headends: Receiving off-air signals for re-distribution via cable, vệ tinh, or IPTV.

• Outside Broadcast (OB) Xe tải & SNG Trucks: Reliable mobile reception for live events.

• Contribution Links: Receiving feeds from remote locations transmitted via DVB-T2.

• Cable TV Operators: Receiving terrestrial channels for inclusion in their cable lineup.

• IP Migration: Facilities transitioning from ASI/SDI to IP can use both outputs during the transition.

• Giám sát & Measurement: Monitoring terrestrial broadcast quality at transmission sites or network operation centers.

• Corporate/Enterprise AV: Distributing broadcast TV within large buildings or campuses over the IP network.

Về bản chất, it’s a high-performance, flexible bridge: It captures fragile over-the-air DVB-T2 signals with maximum reliability (đa dạng) and delivers the decoded content to modern IP-based systems and/or traditional broadcast infrastructure simultaneously. các “Diversity Dual RF Input” is key to its robustness, while the dual outputs (IP & NHƯNG) ensure broad compatibility.**

Hỏi đáp

Q1: Can I get the Transport Stream (TS) output through serial, TTL, or other interfaces instead of UDP?
KHÔNG. The TS (Luồng vận chuyển) output of this DVB-T2 decoder is available only via the Ethernet port using UDP protocol. This model does not support TS output through serial (UART), TTL, or other low-speed interfaces.

Q2: Why is TS output not available through serial or TTL?
A DVB-T2 Transport Stream typically has a high data rate, often reaching tens of Mbps, depending on the broadcast configuration.

nối tiếp (UART) or TTL interfaces are designed for low-speed data communication such as control commands or configuration. Their bandwidth is usually limited to:

• Standard UART: thường ở dưới 1 Mb/giây

• Even high-speed TTL serial: still far below the required TS bitrate

Because of these physical bandwidth limitations, serial or TTL interfaces are not suitable for transmitting a full real-time MPEG Transport Stream.

Ethernet, mặt khác, provides sufficient bandwidth and stable transmission performance, which is why TS output is supported via UDP over Ethernet.

Q3: Can this DVB-T2 decoder board be controlled via RS232?
Vâng. This DVB-T2 decoder control board supports RS232 serial control. Users can send commands through the RS232 interface to configure and control the device.

• The serial communication structure
• Định dạng lệnh
• Control commands and response handling
• Initialization and configuration procedures

Q5: Do you provide technical support for RS232 software development?
We provide the C source code as a reference example.However, we do not provide additional technical support for:

• Custom RS232 protocol development
• Third-party software integration
• Application-layer software modification

Customers are expected to develop and integrate the RS232 control function into their own systems based on the provided reference code.

Q6: What is the purpose of the RS232 interface?
The RS232 interface is designed for:

• Device configuration
• Điều chỉnh thông số
• Chuyển kênh
• Status monitoring
• Remote system integration

It is not intended for high-speed data transmission such as Transport Stream (TS) đầu ra.
