＜Low latency (SRT/H.265 compliant) encoder/decoder＞ VHE-800/VHD-800

SRT/H.265 compliant encoder/decoder

　VHE-800/VHD-800 is IP encoder/decoder with SRT protocol, compatible with H.264/H.265 standard.

　VHE-800 is H.264/H.265 encoder that compresses video and audio signals and provides network distribution functions.
VHD-800 is H.264/H.265 decoder that can be combined with VHE-800 (encoder) to create an optimal environment.
It is compatible with HDMI and 3G-SDI output and uses H.264/H.265 standard for image compression. It delivers high quality images with high efficiency.
It is also equipped with SRT protocol, pursuing more real-time performance and enhanced resistance to packet loss and jitter.

■Compatible with H.264/H.265

　IP encoder/decoder compatible with each of the H.264/H.265 standards.
It is possible to switch streams between the same method.
Adopting the H.265 standard allows video file size to be approximately half that of the H.264 standard for the same image quality,
resulting in less bandwidth burden and more efficient video distribution.

■Equipped with the SRT protocol　

　It is equipped with the SRT protocol, which is ideal for video streaming and broadcast live relay, and compatible with both Caller and Listener.
It is more real-time and enhance error resistance, making it ideal for streaming video, live broadcasts, and other environments.
SRT is a streaming transmission technology that allows video, audio, and metadata to be sent entirely via P2P,
with low latency streaming, excellent error recovery capabilities, high security and inter-device network connectivity.

　It is adapted to applications that emphasize both packet loss and jitter tolerance.

■Low latency transmission by intra-slice technique (<33ms)

　The intra-slice technique divides a video frame into multiple slices and encodes each slice individually
before sequential transmission to achieve low latency video transmission. Receiver decodes sequentially and reconstructs the entire frame. It is suitable for real-time communication and interactive environments that require lower latency.

■Seamless image switching by multicast address switching

　Multicast address switching eliminates switching moments when delivering video and images, providing smoother delivery and playback.

■Compatible with RTMP and RTSP protocols

　Compatible with RTMP and RTSP protocols to deliver high-quality, stable streaming video.

　It handles playback and control of video streams independently and can be used on many devices.

■Possible to high-quality video distribution between locations

　It can display images from each location in high quality over a network.
It uses the H.265 standard and SRT protocol, so it can be distributed via the cloud and to smartphones and tablets.
It has enabled multi-real-time delivery.

■HDMI/3G-SDI output

　It supports HDMI and 3G-SDI output, enabling high quality output for in-situ monitoring and large displays.

System Configuration

Combination of VHE-800 and VHD-800 enables network distribution with lower latency and higher image quality
