Four-Channel HD Encoder
HS-5504-HD

HS-5504-HD 4-in-1 HDMI HD Encoder is a professional high-definition audio/video encoding and multiplexing solution. This device supports 4 channels of HD HDMI audio/video capture, 4 channels of SD AV video capture, and 4 independent 3.5mm external audio inputs. It encodes and outputs dual-stream H.264 video formats with MP3/AAC audio formats. Encoding bitrate is adjustable, and image quality is controllable. Supports transmission via protocols including HTTP/RTSP/RTP/RTMP/UDP. Easy to use with no hardware compatibility issues.

AVC/H.264 Quad-Channel HDMI HD Encoder supports four HDMI HD signal inputs. It encodes these signals using H.264 video and MPEG-1 audio codecs to form a TS multiplexed stream or generate four independent IP streams (4xSPTS). The output interface is IP (TS over UDP). This encoder is primarily used for HD signal broadcasting in digital TV headend live systems and for encoding implementation in IPTV live systems.

Product Features
01
Multi-channel Signal Acquisition and Encoding
Supports simultaneous input of up to 4 high-definition video signals, including common interface types such as HDMI, SDI, and CVBS. These analog or digital signals are then converted into mainstream compressed digital formats like H.264 and H.265 (HEVC). This process significantly reduces video data volume while maintaining video quality, facilitating efficient transmission and storage.
02
Support for multiple encoding formats
In addition to mainstream H.264 and H.265, some high-end models also support encoding formats like MPEG-2 and MPEG-4 to accommodate different application scenarios and device compatibility requirements. For instance, H.265 can save approximately 50% bandwidth compared to H.264 while maintaining equivalent image quality, making it more suitable for bandwidth-constrained network environments.
03
Resolution Adaptation
Supports resolution adjustment for input video signals, enabling the unified encoding of input signals with different resolutions into output signals of a specified resolution, such as 1080P or 720P, to meet the requirements of various display devices or transmission platforms.
04
Frame rate control
The frame rate of videos can be adjusted. Common frame rates include 25fps, 30fps, 60fps, etc. Select an appropriate frame rate based on actual requirements to balance bandwidth usage while ensuring video smoothness.
05
Multi-channel Signal Acquisition and Encoding
Supports simultaneous input of up to 4 high-definition video signals, including common interface types such as HDMI, SDI, and CVBS. These analog or digital signals are then converted into mainstream compressed digital formats like H.264 and H.265 (HEVC). This process significantly reduces video data volume while maintaining video quality, facilitating efficient transmission and storage.
06
Picture Quality Adjustment
Features adjustable parameters such as brightness, contrast, and saturation to optimize video picture quality, ensuring the output video better meets viewing requirements.
07
Support for multiple network protocols
Supports multiple network transmission protocols including RTSP, RTMP, HTTP, HLS, and UDP, enabling the transmission of encoded video signals over local area networks or the internet to various receiving devices such as monitors in monitoring centers, mobile phones, and computers.
08
Adaptive Bitrate Adjustment
Certain models feature adaptive bitrate functionality, automatically adjusting video encoding bitrates based on network bandwidth fluctuations. This ensures smooth video transmission even during unstable network conditions, preventing issues like stuttering or pixelation.
09
Web Management Interface
Typically equipped with a web management interface, users can log in to the device via a browser to perform parameter configuration, status monitoring, firmware upgrades, and other operations, offering simple and convenient operation.
010
Remote Control
Supports remote control via the network, enabling users to manage and operate encoders from remote locations, facilitating centralized management and maintenance of equipment.
011
Logging
The device can record operational logs, such as startup times, fault information, and changes in coding parameters, facilitating troubleshooting and analysis of equipment performance.
012
Audio Encoding and Synchronization
Not only can it encode video signals, but it also encodes accompanying audio signals, supporting audio encoding formats such as AAC and MP3, while ensuring synchronized audio-video output.
013
Alarm linkage
Certain models feature alarm input/output interfaces that can integrate with alarm devices. Upon an alarm event, these interfaces trigger actions such as video recording and screen switching, thereby enhancing the security of the surveillance system.
