HD Encoder + ASI Transcoder

HD Encoder + ASI Transcoder is a multifunctional professional studio and head-end device that integrates MPEG-2 and MPEG-4 AVC/H.264 compression technologies with advanced ASI transcoding and IP streaming capabilities. Equipped with two independent encoder/transcoder modules, the system supports HDMI, SDI, CVBS, and ASI inputs, making it suitable for IPTV distribution, broadcast transmission, and digital TV head-end applications.

This powerful encoding system is capable of processing SD and HD signals up to 1080i, encoding them into MPEG-2 or H.264 (High/Main Profiles), or transcoding existing ASI transport streams into new formats. The encoder is designed to process SD/HD HDMI / SDI / CVBS signals according to MPEG-4 AVC (MPEG-4 Part 10), ITU-T H.264, ISO / IEC MPEG-4 Part 10, and MPEG-2 standards. In HD and SD modes, it supports High Profile and Main Profile from Level 1 to 4.2, ensuring exceptional flexibility for DVB broadcasting and IP streaming infrastructures.

The device can simultaneously generate high-resolution and low-resolution versions of the same program, making it ideal for mobile streaming, web platforms, or bandwidth-constrained networks. With 4 IP outputs (MPTS/SPTS) and 2 ASI outputs, operators can distribute encoded or transcoded programs across IPTV, DVB, and OTT delivery systems with ease. Output settings allow routing one encoded input channel to one output as SPTS or configuring a multiplexed MPTS stream including both encoded channels. Optional features include low-delay mode (≤100 ms) and an integrated color-bar generator with sound for test signal output.

✅ Optimized for Hybrid Encoding & Transcoding Workflows

The HD Encoder + ASI Transcoder performs dual-channel encoding from HDMI/SDI/CVBS or dual-channel transcoding from ASI inputs. It integrates PSI/SI table processing, PID editing, multi-bitrate transcoding, test signal generation, and CAS/EPG support for DVB environments. Operators can route either SPTS or multiplexed MPTS streams to IP or ASI outputs, and the encoder/transcoder mode is selected in management software for flexible head-end configuration.

✅ High-Performance MPEG-2/H.264 Processing for SD & HD Sources

Supporting encoding profiles up to H.264 High Profile Level 4.2 and MPEG-2 HP@HL, the device ensures visually clean, stable video with adjustable CBR/VBR rates from 0.5 to 15 Mbps. The system’s advanced GOP structures (IBBP/IPPP) and chroma 4:2:0 format maintain broadcast-grade quality across mixed-resolution sources. It also supports digital-to-digital decode and re-encode with minimum video quality loss in transcoder mode.

🛠️ The HD Encoder + ASI Transcoder offers easy configuration through web-based management, enabling full control of encoding profiles, transcoding modes, audio/video parameters, output multiplexing, and test signal activation. Operators can switch input sources in software, configure PIDs, enable low-delay mode, manage 4×IP + 2×ASI outputs, and enable or disable the integrated color-bar generator with sound. The system integrates seamlessly with DVB modulators, IPTV middleware, and digital head-end equipment.

🛒 This device is ideal for broadcasters, IPTV operators, telecom providers, and head-end integrators that require hybrid HDMI/SDI/CVBS encoding and ASI transcoding in a single unit. With support for MPTS/SPTS, CAS/EPG, low-latency operation, multi-bitrate transcoding, and up to 4 transcoded programs in transcoder mode (2 transcoded programs from each transcoder), it simplifies deployment in IPTV hotels, centralized AV systems, control rooms, and digital TV networks.
