The DTV opportunity (ARTICULATED 3.5 YEARS AGO)

Ultimate digital information

FEATURES

A discontinuity created by the

imminent analogue to digital transition in the TV market offers

a chance to open a vast new market to Intel microprocessors.

- interactive content

- 500x data delivery

- broadcast SW dist.

Ongoing efforts:

- Intercast (data over NTSC VBI)

- DVB broadcast

- hybrid app technology

- SW MPEG

  • Introduce new (PC) differentiators to the TV market:

    • - intelligence level (MIPS) - local filtering (only present what the user wants)

    • - personalization (learn the user’s habits)- quantity of digital storage

    • - I/O devices (physical & virtual)- object detail capability (3D etc.)


Dtv research program mission 2 year old foil

DTV research Program mission:(2 year old foil)

Substantiate the notion that:

As DIGITAL TV market develops

the DTV paradigm is redefined from

a passive audio+video delivery mechanism

to a new medium for

non-linear, interactive programming

“experienced BEST” on

Intel inside(TM), DTV receiver-equipped PC


Dtv technical background us atsc terrestrial

DTV Technical Background(US, ATSC, terrestrial)

  • Geographic coverage same as NTSC

  • Video/audio quality substantially improved via use of DIGITAL Codecs: MPEG2 video, AC3 audio

  • Digital, packetized broadcast transmission allows delivery of ANY kind of bits @ 19Mb/sec

  • Several image formats aspect ratios & refresh rates

  • Initially broadcasters get an additional 6Mhz channel for simulcast (concurrent analogue and digital service

  • later the analogue service ends, freeing up RF spectrum


What s changing

What’s changing

  • Analogue -> Digital

    • fidelity improved

    • efficiency improved (more channels in same spectrum)

    • bits are bits - more choices in content

  • Receiver Capabilities RAPIDLY increasing

    • intelligence - once you have enough computer to decoded MPEG2 & AC3 you have a decent computer. Not much more cost to make it reprogrammable

    • rendering (eg. 3D)

    • storage (use disk as a content “cache”).

    • interesting I/O (eg. joystick, camera, stereo displays...)

    • multiple concurrent sources of content (eg. TV & Net & DVD)

  • New media (Internet) encroaching on broadcasting


What s staying the same

What’s staying the same

  • Fundamental strength of the broadcast medium remains efficient concurrent delivery from “1 to millions”

  • Mostly a “Couch Potato Medium” - passive, viewed by several people in living room, has to be easy to use & bulletproof.

  • Not much NEW money in the broadcast industry to pay for aggressive deployment new equipment (head end and receiver)

  • Today’s business models are advertising based

  • Many competing service providers NOT interested in making access to competitors service easy

More choices at the SMART receiver then size of display & volume.Multiple, mixed sources of for data: HYBRID applications.

Some metrics

Some metrics

  • degree of Video On Demand-ness

    • receiver autonomously caches most likely to be requested content

    • carouselling

  • ability to channel surf fast a.k.a. stream acquisition latency

  • cool picture/bit

  • level of Viewer choice

  • ease of navigation - next generation EPGs

  • degree of choice at head-end vs. receiver (provider vs. user interests)

Some details on data broadcasting

Some details on Data Broadcasting

  • The DTV pipe was designed for the “old TV app”, so…

  • The DTV standard contained sufficient detail for delivering digital, compressed Video + Audio…

  • and a note was made that “other ancillary data” was feasible

  • Not a great state of affairs for a “computer guy” with all sorts of ideas for alternative uses for the medium

  • For that reason the S13 ATSC technology group was formed

  • And the standard will have a robust way to deliver ALL kinds of data to ALL kinds of receivers


What does dtv data pipe look like

what does DTV “data pipe” look like?

  • 19Mb/sec raw, per channel. MANY channels.

  • multiple image encoding formats

  • 3 profiles of usage:

    • guaranteed auxiliary broadcast (dedicate some BW to a stream of digital data), analogous to current VBI use 1k-5Mbit

    • opportunistic (use the “spare bits” during low motion periods, stills, subtitles etc. to deliver data at variable bit rate). Could carry both program-related and unrelated data

    • full BW (utilize a whole channel for very high-speed, bulk data delivery)

19Mb/s

What changes when tv broadcast goes digital bits are bits not video bits

What changes when TV broadcast goes digital?Bits are Bits, not video bits.

  • Meaning and encoding of information are decoupled

  • The new medium enables broadcast delivery of ALL TYPES of digital information, beyond pictures and sound

  • EVERY receiver contains a computer

    • RAM and MIPS at least for decoding of MPEG2 & AC3

    • opinions on what kind of computer vary widely :-)

    • users get more choices

  • comparable to transition of audio distribution from LP to CD, which created a new, interactive medium - the CD ROM


Data broadcast applications taxonomy

data broadcast applications taxonomy

  • The range spans orders of magnitude along the axes of Bandwidth & number of users.

  • Other significant characteristics include:

    • reliability of delivery (executable file with 1 bit missing is worthless (or worse!) while a missing pixel does not substantially impact image quality

    • size and duration of the “atomic object” (pager message vs. encyclopedia)

    • latency (emergency message vs. scheduled morning news)

    • real-time vs. time-shifted use (page vs. science lesson)


Some application examples

some application examples:

  • watch-pagers (connected anywhere for critical messages)

  • stock tickers (personalized,valuable real-time data)

  • “your world news” (personalized news)

  • “virtual school house” (personalized, interactive education & information access)*

  • SW distribution (fresh bits with out disks, shrink-wrap, trucks, or shelf-space)

  • “I want to see this ad” (greatly improve targeting adds to willing potential consumers)

* this is a personal favourite of mine - objectively good for ALL, and a great fit for the PC/ATV combination. Anyone that wants to help build it please see me!
