Broadcast Technology Transitions

Black+White TV

Color TV

Digital Production

High Definition

IP 4K HDR OTT


www.telecompro.tv

Transitions

• Black+White to Color

– New signal, same basic wiring (analog coax)

• Color to Digital Production

– Same signal, new transport format (digital coax)

• Digital Production to HD

– New signal, similar transport format (digital coax)

• HD to IP/4K/HDR/OTT

– New signals, new transport format (IP networking)

Why This Transition is Different

• No more dedicated signal paths

– One signal per cable is going away

– Ethernet cable hosts multiple simultaneous signals/types

• Much less broadcast-specific hardware

– Server-based, software oriented

– Adopting technologies that are not custom-built

• Small applicable talent base with experience

– What other markets use 3Gbps single-stream flows?

– Rarely find IT/IP background in broadcast management

Notes from the Teacher

• Media professionals are eager to keep learning

– Approaching 100 days of training in past 4 years

– Open courses for anyone; private classes for some clients

– Typical class has 15-30 students

• First IEEE BTS class was “Bridging the Gap”

– Broadcast Technology Society

– Gap still exists in many organizations today

– People with IT/IP backgrounds vs. broadcast natives


www.telecompro.tv

Who Do We Train for What?

• Our industry already uses a wide range of specialists

– Camera operators, directors, sound crew, tech operations

• Going forward, need expertise in many areas

– Media experts on sound, video, production

– Network experts on storage, processing, streaming

– Need to have a common language to communicate


www.telecompro.tv

Who Needs to Learn What?

Protocol basics: TCP, UDP, RTP, HTTP

Addressing: MAC, IP, Ports

IPv4 vs. IPv6

Jumbo frames, packet overhead

Layer 2 vs layer 3

Unicasting vs. Multicasting

Subnets and VLANs

IGMP, PIM, spoofing

Image formats, Color sampling

Interlaced vs. Progressive

Compression, GOPs, profiles/levels

MPEG2 Transport Streams

Container/file formats, transcoding

Metadata, HANC/VANC embedding

Captions, video description

Media Professionals Networking Professionals


www.telecompro.tv

… and Everyone needs to Learn

Streaming formats - HLS, DASH

Error detection/correction, FEC, SMPTE 2022

Stream encryption, media key management

Content delivery networks (CDNs)

Performance monitoring for time-sensitive streams

IP Network redundancy schemes for live broadcasts
