 SPECIFICATION  FOR DIGITAL TERRESTRIAL TELEVISION  BROADCAST  
SERVICE RECEIVER  
 
 
Introduction  
 
 
Proposition  
 
This document outlines receiver specification which is capable of receiving both Standard Definition 
and Hi gh Definition Digital Terrestrial broadcast for Malaysia.  
 
Items in this specification are divided into ‘Required’ and ‘Optional’ categories. Where a feature is 
stated as ‘Required’, its inclusion is necessary for the achievement of a minimum compliance wi th 
transmission requirements. Additional Optional functions may be added by the vendor to enhance the 
consumer proposition and these will be welcomed. In order to be compliant, where a feature is 
‘Optional’ and is included in an offered receiver design, th e optional feature must be implemented in 
accordance with the associated referenced standards.  The word “shall” implies that the item is a  
requirement ( mandatory ) while the word “may” implies that a requirement is optional.  
 
The term basic profile in this  document refers to the profile for receivers which do not implement the 
interactive application as outlined by 3.2.18.  
 
This specification is not a comprehensive list of all relevant standards relating to consumer equipment 
that can provide digital terres trial reception but rather a list of those standards considered relevant to 
requirements.  
 
The profile is based upon open standards predominantly from the Digital Video Broadcasting (DVB) 
standards  and the European Telecommunications Standards Institute (ETSI).  
 
 
Purpose  
 
The purpose of this document is to describe the requirements for a certified Free to Air Terrestrial 
receiver for Malaysia and to refer to detailed specifications that are required for conformant 
implementation. The profile is in the form  of a hardware specification outline, together with an 
overview of software requirements. The software is to be routinely capable of being upgraded via 
‘through -the-air-download’.  
 
1.  Scope  
 
 
The document sets out to identify the baseline functional speci fication of a H.264 AVC HD digital 
terrestrial receiver including both Set Top Boxes and IDTV’s.  Personal Video Recorders (PVRs) are 
outside the scope of this document.  It is intended that a terrestrial receiver conforming to this profile 
should comprise p art of a domestic installation, in conjunction with an external, fixed wideband 
terrestrial UHF /VHF  antenna input. Set Top Box  output(s) will connect to the television display (and 
possibly other domestic equipment).  
 
It is the aim of the specification to ensure that the approved receiver in Malaysia  satisfies the 
minimum requirements of each broadcaster.

over time. To ensure that the viewer will always  be able to access all services being broadcast to the  
selected region, the receiver must detect and reflect to the viewer any such changes with minimal 
viewer  involvement.  All services have an associated (Logical) Channel Number. Use of the logical 
channel number ensures  that the viewer becomes familiar with a specific remote control unit button 
number for each channel.  Access to, and use of, accurate service information is essential if the viewer 
is to enjoy all of the content  being broadcast.

Note 1There is no allowance for echo outside guard for 19/256 PP4 in Nordig due to 19/256 guard 
(266us) being very close to the Nyquist limit for PP4 (298.67us) . Nordig defines the max delay 
for echo outside guard to be 57/64*Nyquist which is equal to the guard interval of 266usec for 
19/256 PP4. SKMM MTSFB TC T004 :2013
