Why System Integrators Choose HPS946IV Encoder Modulator for Digital TV Headends

Introduction: The Real Challenges System Integrators Face

For system integrators building digital TV headends, the biggest challenges are always the same:
high channel density, multiple signal standards, system stability, limited rack space, and cost control.

Traditional headend architectures require multiple standalone devices—encoders, multiplexers, modulators, IP gateways—which increases complexity, power consumption, failure points, and maintenance costs.

This is exactly why more system integrators worldwide are choosing the Catcast HPS946IV Encoder Modulator as a core headend solution

All-in-One Design That Simplifies Headend Architecture

The HPS946IV Encoder Modulator is a highly integrated headend device that combines:

• HDMI encoding

• Tuner demodulation

• Multiplexing

• RF modulation

• IP & ASI output

All in one professional 1RU chassis.

For system integrators, this means:

• Fewer devices in the rack

• Cleaner system architecture

• Faster installation

• Lower long-term maintenance costs

High-Density Inputs for Medium & Large Projects

System integrators often manage projects that require dozens of TV channels. HPS946IV is designed exactly for this scale.

Flexible Input Options

• 4 / 8 / 12 / 16 / 20 / 24 HDMI inputs (HDCP supported)

• 4 / 8 / 12 / 16 / 20 / 24 tuner inputs

• Supports mixed tuner types:

• DVB-S / DVB-S2

• DVB-C

• DVB-T / DVB-T2

• ATSC

• ISDB-T

HDMI and tuner inputs can also be freely combined, giving integrators maximum deployment flexibility.

Broadcast-Grade Encoding Quality

For professional headends, signal quality is non-negotiable.

The HPS946IV provides:

• MPEG-4 AVC / H.264 video encoding

• CBR mode for stable transmission

• Full HD support up to 1080p

• Audio encoding:

• MPEG-1 Layer II

• LC-AAC

• HE-AAC v1 & v2

This ensures excellent compatibility with STBs, TVs, CAS systems, and IPTV platforms.

Built-in Multiplexing & Signal Processing

Unlike basic encoder modulators, HPS946IV includes professional multiplexing features, which system integrators rely on:

• PID remapping (automatic & manual)

• Accurate PCR adjustment

• Null packet filtering

• Up to 180 output PIDs per channel

These functions greatly reduce compatibility issues during integration with CAS, scramblers, and third-party headend systems.

Multi-Standard RF Modulation for Global Projects

System integrators working internationally need one device that fits multiple regions.

HPS946IV supports:

• 4 or 8 RF carriers

• RF standards:

• DVB-C

• DVB-T

• ATSC

• ISDB-T

• RF frequency range: 50–960 MHz

• High MER performance (≥40 dB)

This makes the device suitable for Europe, Asia, North America, South America, and Africa.

RF + IP Output for Hybrid Headends

Modern headends are rarely RF-only.

The HPS946IV supports:

• Gigabit IP output

• SPTS & MPTS

• UDP / RTP / RTSP protocols

• Unicast & multicast

• 2 independent ASI outputs (MPTS copy)

This makes it ideal for hybrid CATV + IPTV headends, especially in:

• Hotels

• Hospitals

• Campuses

• Residential networks
