TV DISTRIBUTION

Black Swan's TV Distribution engineering builds high-density QAM/COFDM modulators, optical transmitter nodes, and IP transport gateways, ensuring broadcast signals reach viewers with maximum Signal-to-Noise Ratio (SNR) and zero packet loss.

Core System Capabilities

High-Density RF Modulation

Up to 64 QAM / COFDM carrier frequencies modulated per 1U hardware frame.

SRT & RIST IP Transport

Error-corrected low-latency video transport across public internet links.

Optical Fiber Nodes

High-power 1550nm optical transmitters and erbium-doped fiber amplifiers (EDFA).

Automated Redundancy

1+1 optical and RF automatic protection switches (APS) for zero downtime.

Ensuring Broadcast Signal Integrity Across Terrestrial & Cable Networks

Whether delivering signals across city-wide coaxial cable networks or connecting transmission towers via optical fiber, television distribution demands strict signal calibration. Black Swan provides complete carrier-grade RF headends and optical transport systems.

SRT & RIST Protocols for Internet Video Backhaul

Satellite backhaul can be expensive for regional stations. Modern Secure Reliable Transport (SRT) and RIST protocols allow broadcast feeds to traverse public internet connections with packet loss recovery up to 30%, serving as reliable primary or backup transmission links.

DVB-T2 / DVB-C Digital Multiplexing

Our hardware statistical multiplexers optimize bandwidth allocation across channel bundles, dynamically reassigning bitrates to fast-action sports while maintaining crisp video quality across all multiplexed channels.

Technical Specifications & Standards:

DVB-T2 Single PLP & Multi PLP support
SRT / RIST / Zixi protocol error correction
1550nm EDFA optical amplifier integration
SNMP v2c/v3 remote telemetry monitoring

Turnkey SLA & Engineering Deliverables

Every deployment includes full documentation, factory acceptance testing, and continuous operational guarantees:

DVB-C / DVB-T2 / ISDB-T digital headend multiplexing and RF modulation systems
Long-haul dense wavelength division multiplexing (DWDM) optical fiber transport links
Reliable IP transport (SRT, Zixi, RIST) setup over unmanaged internet infrastructure
RF spectrum analysis, signal balancing, and carrier-to-noise optimization

Frequently Asked Engineering Questions

Q: Can we use SRT over public internet instead of leased fiber?

Yes. SRT protocol provides encryption and ARQ packet recovery, delivering broadcast-grade reliability over internet connections.

Q: How many digital channels can be multiplexed into one DVB-C QAM carrier?

Using H.264/HEVC compression, a single 256-QAM carrier (38Mbps capacity) can carry 8 to 12 HD channels.
