MHEG vs Java

MHEG-5 is designed specifically for TV presentation

Remote control operation

Displays built on TV layout

Works in its own safe memory space

Robust interpreted language

Java is a complex general purpose tool with adaptations for TV

As illustration of comparable complexity

MHP (based on Java) has >10000 unit testsf There are no other standardised Java systems for TV

MHEG has

MHEG applications are smaller

Source: MHP/MHEG Coexistence project. BBC Research.

Smaller applications means faster start and lower cost transmission

MHEG applications have been designed to compete with almost all common MHP functionality


9/31


MPEG-4 and MHEG-5

Inclusion of HD/SD MPEG-4 in the system makes adifference to a number of issues

Cost of silicon

Number of receiver suppliers in short term

Complexity of receiver outputs

MHEG-5 display strategy for HD services

Receiver costs are higher in short term

but bandwidth utilisation is better

Next generation iDTV will include MPEG-4

Receiver solutions have easy IP connection

MHEG-5 HD support launched in 2008 (Freesat in UK)

12/31


Conformance Regime

In UK conformance regime was weak until 2005/6.

Many problems arose from this, especially for retailers

A tough conformance regime, using Pass/Fail tests to

achieve brand acceptance, is recommended forSI, Subtitles, MHEG-5, RF, OAD, AFD, etc

OAD capability is essential for all receivers

Much can be derived or licensed from DTG in UK

Including subcontracting work
