HaiweiTech HSC-S1 H.264/H.265 HDMI Encoder and Decoder User Manual

1. Introduction

The HaiweiTech HSC-S1 (Haiwei SynCodec) is an embedded hardware solution designed for point-to-point interactive transmission and emergency communication. It also functions as an IP transcoder. The HSC-S1 can receive streams and output them via HDMI or a 3.5mm composite jack, while simultaneously sending streams using various IP protocols such as RTSP (over UDP & TCP), RTMP, HTTP, UDP, Unicast, Multicast, and ONVIF. It features SDK decoding for ultra-low latency local network transmission, bypassing the need for a server in P2P solutions.

2. Key Features

• Input Capabilities: Supports 1-channel H.264/H.265 IP input (RTMP/RTSP/RTP/HTTP/HLS/UDP/P-P/SDK), 1 Full HD HDMI input (resolutions up to 1920x1080, minimum 320x180), and 1 Line-in audio input.
• Output Capabilities: Features RS485 output. For decoding, it provides HDMI, CVBS, and Audio outputs. For encoding, it supports RTMP/RTSP/RTP/HTTP/HLS/UDP/P-P/SDK. In Encode+Decode mode, it offers IP out with Picture-in-Picture (PiP). In Encode+Loop mode, it provides IP out and HDMI loop-through.
• Advanced Video System: Built on an advanced encoding and decoding architecture, the HSC-S1 is suitable for video conferencing, interactive communication solutions, and direct stream transmission without requiring a third-party server.
• Additional Services: SDK/API availability, IP finder tool, video management platform, and iOS/Android APP (LiveX) support.

4. Setup Instructions

1. Connect Video Source: Connect your video source (e.g., camera, PC) to the HDMI-IN port on the HSC-S1 using a standard HDMI cable.
2. Connect Display (Optional): If you intend to use the HDMI loop-out function, connect a display device (e.g., monitor, TV) to the HDMI-OUT port.
3. Connect Audio (Optional): For audio input, connect your audio source to the AUDIO-IN port. For analog audio output, connect to the AV-OUT port.
4. Network Connection: Connect the HSC-S1 to your local network using an Ethernet cable plugged into the LAN port.
5. Power Connection: Connect the provided 12V DC power adapter to the DC 12V input on the device and then plug the adapter into a power outlet.
6. Power On: The device will power on automatically. The LED indicator will illuminate, signifying that the device is operational.
7. Web Interface Access: Use the provided IP Finder tool or your network's DHCP server to locate the device's IP address. Access the device's web-based configuration interface by entering its IP address into a web browser.

5. Operating Modes

The HSC-S1 supports five distinct operating modes, configurable via the web interface:

1. Encode Only: In this mode, the HDMI input signal is encoded and streamed out via IP protocols. The HDMI output port is disabled.
2. Decode Only: The device receives an IP stream, decodes it, and outputs the video via HDMI and/or the 3.5mm composite jack. The HDMI input port is disabled.
3. Encode + Loop: The HDMI input signal is simultaneously encoded for IP streaming and passed through to the HDMI output port, allowing for local monitoring of the input source.
4. Encode + Decode: Both the HDMI input and an IP input stream are active. This mode enables Picture-in-Picture (PiP) functionality, allowing for the combination or overlay of both video sources.
5. Transcode: The HSC-S1 receives an incoming IP stream, transcodes it (e.g., changes codec, resolution, bitrate), and outputs it as a new IP stream.

6. Applications

The HaiweiTech HSC-S1 is suitable for a wide range of professional applications, including:

• Broadcasting
• Point-to-point video transmission
• IP/video Transcoding
• Live Streaming events
• Multimedia Screen Splicing
• CCTV/video Surveillance and Monitoring
• Emergency communication systems

8. Package Contents

The HaiweiTech HSC-S1 package includes the following items:

• 1x HSC-S1 Unit (Encoder and Decoder)
• 1x HDMI Cable
• 1x Power Adapter (DC 12V)
• 1x 3.5mm Audio Cable
• 1x CVBS Cable
• 1x Guarantee Card

9. Troubleshooting

• No Power: Ensure the power adapter is securely connected to both the device and a functional power outlet. Check the power LED indicator.
• No Video Output: Verify all HDMI cable connections are secure. Confirm that the correct operating mode (e.g., Decode Only, Encode + Loop) is selected in the web interface. Check display input settings.
• No Network Connection: Ensure the Ethernet cable is properly connected to the LAN port and your network. Check network settings (IP address, subnet mask) in the web interface. Use the IP Finder tool to locate the device on your network.
• Audio Issues: Verify all audio cable connections (AUDIO-IN, AV-OUT). Check audio input/output settings and volume levels within the device's web interface.
• High Latency: Ensure your network is stable and has sufficient bandwidth. For point-to-point solutions, utilizing SDK decoding can help achieve ultra-low latency.
• Web Interface Unresponsive: Try restarting the device. Ensure your computer is on the same network segment as the HSC-S1.
