WHY ME?norpak corporation is:

WHY ME?WHY ME?norpak corporation is:norpak corporation is:

n Developer of the packet multiplexed data broadcast concepts and standards. 22 years of experience. Interactive TV again and again

n The leader in TV Data Broadcasting products - believe 90% of the world market

n Over 3,400 NTSC/ PAL/ SECAM, 525/625 line systems in 42 countries. All major data formats. Analogue, serial digital and HD


WHAT DATA?WHAT DATA?n NEEDS TO SYNCH WITH THE VIDEO AND SOUND

- CAPTIONS ATVEF TRIGGERS

n NOT SYCHED BUT NEEDS TO STAY WITH THE VIDEO AND SOUND - METADATA

n THAT NEEDS TO STAND THE ‘TEST OF TIME’ AND ‘MURPHY’S LAW’

n THAT LENDS SOME ORDER TO THE CRAZY WORLD OF DIGITAL EMISSION FORMATS

n LETS CALL IT ‘STICKY’ DATA


DATA DATA -- TWO MARKETSTWO MARKETS

n COMMERCIAL& Usually closed system - some encryption& Network internal use, financial, government& New HD applications - metadata

n CONSUMER& Interactive TV, PVRs, captions, EPGs


COMMERCIALCOMMERCIAL

n PC target delivery - best place to insert the data is at the point of emission. Many speakers will be addressing those opportunities.

n ‘Internal’ use. Present minimal use of ‘metadata’ takes off with DTV. Motion picture data, rights data, assets management, etc. A focus of increasing standards work. Needs to be inserted at the start of the process

‘STICKY’ DATA‘STICKY’ DATAnMost solutions are focussed on adding data at the

point of emission. This is fine for data which is unrelated to the video/sound

n ‘Sticky’ data is content that needs to ‘stick’ with the V/S as it travels through multiple plants on its way from the creator to broadcast

n Needs to be transparently stored and retrieved without the complications of locating it on a server somewhere. Delays of seconds, hours, days are commonplace - and what about years down the road?


FORWARD / BACKWARD FORWARD / BACKWARD COMPATIBILITYCOMPATIBILITY

n Whether the signal is analogue, serial digital or HDTV the ‘sticky’ data interface should be the identical

n Applications such as captioning, VChip, XDS and ATVEF URLs should interface to the data encoder in the same way regardless of the TV standard used

n Makes the move from analogue to digital or HDTV simple and straightforward .


SMPTE 334MSMPTE 334M

n The new standard for adding data to the SMPTE 292M signal using proven broadcast procedures and processes

n VANC in the SMPTE 292M stream means that the combined V/S/D can be switched, routed, and stored using familiar processes

n Captioning, VChip and ATVEF interactive data injection continue to be done at the same point in the process, using the same tools and in the same way as it presently is done

CONCLUSIONCONCLUSION

·NEW SMPTE334M STANDARD DEFINES METHOD OF CODING DATA FOR DTV. WORKS WITH BOTH 292 AND 259 SIGNALS

·OFFERS SIGNIFICANT BANDWIDTH, SUPPORTS MULTIPLE DATA TYPES, ESPECIALLY VALUABLE FOR ‘STICKY’ DATA

· EQUIPMENT IMPLEMENTING THE STANDARD IS NOW AVAILABLE
