4. General Requirements:
4.1 Performance Requirements
i.
The manufacturer shall ensure compatibility/interfacing of STBs
with consumer electronic equipment, such as televisions, audio
systems, VCRs, etc., in the country. Audio and video interfaces that
provide such compatibility are listed in Table I. below.
ii.
The STB shall support reception and processing of EN 300 429
(DVB-C) compliant digitally modulated signals. It shall be able to
receive and process Service Information (Sl) as laid down in EN
300468 and ETR 211. For data services (if implemented), it shall be
able to receive data bit streams compliant to EN 301192 and ETSI
TR 101202.
iii.
The STB Software has to provide the information of the signal level
and signal quality.
iv.
The STB has to be provided with a cold start time of no more than 40
seconds and a start time from standby mode to no more than 10
seconds.
v.
The STB hardware design has to be provided with an Annualized
Failure Rate (AFR) of not more than 2% over 3 years.
vi.
The STB is required to support the “Hardware root of trust” concept
by locking each STB uniquely to the CAS embedded in a secured
chipset.
vii.
The STB should support a smart card/ cardless CAS solution
4.2
Video and Audio Decoding Requirements:i.
ii.
iii.
iv.
The STB’s video decoder shall fully comply with the DVB
Implementation Guidelines for the use of MPEG-2 (SDTV) and
MPEG-4 H.264/AVC (HDTV) video in cable ETSI TS 101 154.
Up-sampling of sub-sampled resolutions shall be made in accordance
with ETSI TS 101 154 [28], i.e. sub-sampled luminance resolutions
shall be up-converted by the Decoder Format Converter into the full
video raster of the Decoder Composition Output.
The STB’s video decoder shall fully comply with standard ISO IEC
14496-10 [8] for decoding MPEG-4 and ISO/IEC 13818-2 [9] for
decoding of MPEG-2 coded signals. The decoder must also comply
with ETSI TS 101 154 [10] and must support VBR and CBR.
The STB’s video decoder shall ensure synchronization between audio

xi.
xii.
more than 20 milliseconds, and must never lag the video by more
than 45 Ms.
The STB’s video decoder shall be able to switch between 4:3 and
16:9 picture aspect ratios. In case of receiving an anamorphic picture
and pre-set 4:3 on TV, the STB shall perform conversion to «16:9
letterbox»
In case of RCA, or if any other analogue video output (YPbPr or
RCA) is available, the decoded HD video must be down-converted by
SD format converter to SD resolution for output via these interfaces.
This will ensure compatibility of the STB with the TV sets that do
not have digital interfaces. Picture down-conversion must be
implemented from any of the incoming encoded HD full screen
luminance resolutions of 1920x1080 and 1280x720 (as an OPTION
also from 1440x1080, 1280x1080, 960x1080, 960x720 and 640x720)
to 720x576 SD resolution. The down-converted video must be
displayed as 16:9 letter box on 4:3 displays. The SD format converter
should apply appropriate re-interlacing.
The STB’s audio decoder shall support reception of multi-channel
(up to 5.1) audio, in addition to the mandatory SDTV audio decoder
requirements. The STB shall provide analogue audio outputs for
stereo/mono, S/PDIF output and an HDMI output for multi-channel
audio.
The STB’s audio decoder shall provide at least one stereo audio
decoder that is able to meet minimum decoding requirements, based
on MPEG 1 Layer II ("Musicam" ISO/IEC 11172-3).
The STB’s audio decoder shall also support AAC decoding according
to ISO/IEC14496-3 subpart 4.
The STB’s audio decoder shall fully comply with DVB
Implementation Guidelines for the use of MPEG-2 Systems, Video
and Audio in satellite, cable and terrestrial Broadcasting Applications
ETSI TS 101 154.
The STB’s audio decoder shall support decoding of audio in the
following modes: dual mono, stereo and joint stereo.
The Set-Top Box (STB) shall comply with ETSI EN 50221; Common
Interface Specification for Conditional Access and other Digital
Video Broadcasting Decoder Applications
4.3 Equipment Conformity
The set top box shall comply with the international standards according to the
DVB- organization and the essential requirements of the CE (European
Conformity) and the apparatus shall bear the related conformance mark.
4.4 Electronic Program Guide
The set top box shall provide a complete list of channels and an Electronic
Program Guide containing all event information for all program channels on
the available multiplexers.
4.5 Logical Channel Numbering
The set top box shall support Logical Channel Numbers associated to the local
television-stations and must be unique within the network.
