Multimedia tec nolog covers a wide ran e of tec nical are s an in olves a n mb r of

tec nical elements Most of the tec nical elements for multimedia are now b in develo ed

an updated IEC stan ardization activities on the multimedia tec nolog , theref ore, s ould

b car ied out with enou h dis u sion an clarifi ation on

• p sition an relation hip of the tec nolog to b stan ardized amon the colection of

related tec nologies,

• s o e an framework/g idel ne of the stan ardization,

• a pro riate stan ardization organisation havin the resp n ibi ty,

• s hed le of the stan ardization,

• relation hip b twe n new work items an the existin stan ard on multimedia or sin le

medium tec nolog

These dis u sion s ould b b sed on a pro riate multimedia tec nolog models to cre te a

f ramework for multimedia stan ardization

The f irst edition of this Tec nical Re ort was a s a s ot of these dis u sion in IEC/TC 10

with con ideration of the draft IEC PACT (President's Ad isory Commite on Future

Tec nolog ) re ort whic was a stu y an forese r on f uture tec nolog Af ter that, TC 10

had b en en aged in stan ardization of au io, vide an multimedia eq ipment an s stems

f or over ten ye rs

In 2 10, TC 10 /AGS (Ad isory Group on Strateg ) started to stu y future tec nolog again

b cau e some of ten ye rs of progres of tec nolog had re c ed b yon the IEC PACT

f orese r The stu y was FT-TG (Future Tec nolog Tas F rce) that stu ied the tec nolog

f orecast in the ne r future an res lted to raise Stu y Ses ion in AGS to initiate the new

tec nolog are s in TC 10 At the same time, the ne d to revise IEC TR 619 8 was

recog ized

This new edition of this Tec nical Re ort is b sed on the IEC PACT re ort an redef i es the

TC 10 s stem model to initiate the f uture TC 10 stan ardization work This Tec nical

3 Terms and definitions

For the purp ses of this doc ment, the fol owin terms an def i ition a ply

The generic model clarif ies AV an IT multimedia tec nolog an its b u daries

Stan ardization is in general req ired to o tain the f ol owin :

• ph sical an logical con ectivity;

• en ironmental saf eg ard

The major purp ses of multimedia stan ardization are:

Trang 10

• ph sical an logical con ectivity

Multimedia data interc an e an distribution are b sed on commu ication media an

interc an e ble storage media Protocols, formats, interfaces, an other data stru tures

of the media are req ired to b stan ardized The f eatures of multimedia data, in

p rtic lar, make those stan ard more compl cated than in the case of a sin le medium

• u a i ty an ac es ibi ty

Multimedia s stems contain a n mb r of b sic sin le medium p rts, e c of whic

req ires a pro riate interaction with an u ers or other s stems In order to re l se

f easible an h man- ecog isa le o eration for the multimedia s stems, simpl f ied an

stan ardized u er s stem interfaces are es ential

• saf ety an sec rity

Multimedia eq ipment an s stems f orm or wi f orm a b sic an imp rtant infrastru ture

of national an international activity Some multimedia data are req ired to b hig ly

sec red Some s stems are req ired to b stron ly protected an b sides their o eration

con ur ently to their cor esp n in media; visible, au ible, an other sen ible media Safe

an sec red en ironments s ould b implemented by b in b sed on some g idelne an

Al the s bjects to b stan ardized f or this purp se can b model ed by the relation hip

b twe n an originator an a recipient as s own in Fig re 1

When con iderin ph sical an logical con ectivity, as presented in Fig re 2, an originator is

p sitioned to b an entity, s stem or device whic provides inf ormation A recipient s ould b

an entity, s stem or device whic receives the inf ormation They are recon ected with e c

other by a relation hip: information tran fer The information tran fer can b car ied out by

dif ferent typ s of inf ormation tran f er media Another asp ct of the information tran f er is a

4.2.2.1 Inters stem model

The ph sical media f or inf ormation tran f er b twe n s stems are clas ified into:

• Bro d astin media

Bro d astin media s p ort simultane u information tran f er to a n mb r of recipients

Examples of the wireles bro d astin media are BS, CS an ter estrial

• Intercommu ication media

Intercommu ication media s p ort inf ormation tran f er b twe n two or more s stems at a

time Examples of intercommu ication media are Internet, WAN, LAN an an are

network

• Interc an e ble storage media

Interc an e ble storage media (ISM), e.g o tical dis s f aci tate data tran fer by alowin

the ph sical movement of the ISM from s stem to s stem L rge amou ts of data tran f er

can inexp n ively an q ic ly b re l sed by u in interc an e ble storage media

4.2.2.2 Inter-de ic (intra-s stem) model

Mec anisms f or information interc an e b twe n devices or s bs stems within a larger

• computer an p ripheral interf ace s c as USB an Wi-Fi direct;

4.2.3 Tra sf er e data structure

4.2.3.1 Data structure in inters stem/intercommunic tion me ia

Tran f er ed data stru tures employed in inters stem/intercommu ication en ironment may b

re resented by the OSI layered model whic was stan ardized by ISO/IEC 74 8-1 The data

stru ture con ists of seven layered protocols, semantic an s ntactic b haviors of whic are

def i ed an tre ted in cor esp n in p er to-p er entities within commu icatin o en

s stems

The to layer entities f or a pl cation protocols provide services to their a pl cation itself within

an o en s stem Ap l cation data whic are outside the s o e of the OSI model can b

con idered from the fol owin p ints of view:

• Content

A major f eature of multimedia s stems is that multiple typ s of content data are s p orted

by the s stems

• Stru ture

Multiple typ s of content data are integrated into a stru ture whic is a pro riate for the

a plcation An in tan e of multimedia data stru ture model n is s own in 5.1
