FOREWORD
(Formal clauses will be added later)
1 SCOPE
This standard specifies the requirements of a digital Set Top Box (STB), for use by the subscribers
to receive IPTV services delivered to the viewers homes using a Hybrid Fiber Coaxial (HFC) last mile access network. In this set up, the coaxial cables to individual homes are finally terminated in a
DOCSIS (1.1 or 2.0) Cable Modem. A number of cable modems in a locality are connected to a
Cable Modem Termination System (CMTS), which in turn is connected to a back bone broad band
bi-directional IP Network. In the home, the IPTV STB is to be connoted to the Cable Modem using
a 10/100 Base T Ethernet connector.
Alternately the STB could also used for receiving IPTV services delivered using high speed Digital
Subscriber Line (DSL) based access technologies (ADSL2, ADSL2+, VDSL etc.) or for receiving
services delivered via a broadband modem connected to a 4G network. In this case STB is to be
connected to the DSL Modem or the Broadband Modem using the Ethernet connector.
2 REFERENCES
The standards listed in the Annex A and Annex B contains provisions, which through reference in this text calibrate provisions of this standard. At the time of publication, the editions indicated were valid. All the standards are subject to revision and parties to agreement based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standard indicated in the Annex A and Annex B.
3 REQUIREMENTS
3.1 The IPTV STB shall be based on open (non proprietary) architecture and shall ensure technical
compatibility and effective interoperability amongst different IPTV services in the country. The
interoperability shall be achieved by complying with the following ETSI standards:
a) TS 102 034 V1.4.1: Transport of MPEG-2 based DVB Services over IP based networks.
b) TS 102 542 V1.2.1: Guidelines for the implementation of DVB IP Phase 1 Specifications.
c) c)TS 102 539 V1.2.1: Carriage of broadband guide content information over IP
-
d) 4. TS 102 824: "Digital Video Broadcasting (DVB); Remote Management and Firmware
Update System For DVB IP Services".
e) 5. TS 102 366 V1.2.1: Digital Audio Compression (AC-3, Enhanced AC-3) Standard
3.2 Specifications
The specifications for the various features and capabilities for the STB shall be as given in Clause 4.
3.3 Performance Requirements
The performance requirements for the IPTV STB are given in Table 1.
3.4 Safety Requirements
The safety requirements of the STB shall conform to IS 13252.
3.5 Electromagnetic Compatibility (EMC) Requirements
The EMC requirements of the STB shall conform to IS 6873 (Part 3).
4 SPECIFICATIONS
4.1 Software Specifications
4.1.1 The STB shall have the capability to receive the following three types of services delivered using
RTSP as defined in Sl No. 1 of Annex B.
a) Live Media Broadcast (LMB): Delivery in Unicast or Multicast
b) Media Broadcast with Trick Modes (MBwTM): Delivery in Unicast only.
c) Content on Demand (CoD) Delivery in Unicast. User initiates a presentation
4.1.2 The complete protocol stack used for the delivery of the services mentioned in Clause 4.1.1
above, is described in Clause 4 of Sl No. 1 of Annex B..The detailed description of the process of
encapsulation of the MPEG-2 transport stream packets carrying Audio/video streams and service
information (DVB SI), into RTP packets and their transport over the IP network is given in Clause
7 of Sl No. 1 of Annex B. The IPTV STB should conform to this complete protocol stack.
The carriage of DVB-SI in transport streams is described in Clause 7.1.2 of Sl No. 1 of Annex B.As
per this the following are applicable:
a) Carriage of PAT & PMT is mandatory on all transport streams.
b) Option 1: Carriage of all DVB SI tables except NIT (TS-Full SI)
c) Option 2: Carriage of tables other than PMT & PAT is optional (TS-Optional SI)
4.1.3 The STB should have the capability to decode MPEG -2 MP@ML SDTV and optionally
MPEG-4 Part 10 AVC HP@L4 HDTV signals.
4.1.4 The STB should have the capability to decode one or more of the following formats: MPEG-1
Layer2, E-AC3 Stereo, MPEG-4 HE AAC Stereo, MPEG-1 Layer3. If any multi channel audio is
available, it should be transcoded and passed through to an S/PDIF if available.
-
4.1.5 On connection to the network, the IPTV STB should send a broadcast query requesting info from
the DHCP server. On receiving this request, the DHCP server will assign an IP address to the STB.
This process is defined in detail in Clause 8 of Sl No. 1 of Annex B.
4.1.6 DVB has defined a Service Discovery / Selection (SD&S) process in Clause 5 of Sl No. 1 of
Annex B. SD&S protocol for multicast services is transported in IP packets in accordance with the
DVB STP protocol whereas for Unicast services SD&S info is transported in HTTP. Using this
information the IPTV STB should build a list of service providers and the different services
available from each service provider.
4.1.7 Clause 9 of Sl No. 1 of Annex B specifies the File Upload System Stub (FUSS), which is
mandatory and allows the system software of an IPTV STB to be updated on a power-cycle or
reboot. The sending of the system software will be handled by the mechanisms specified in Sl No. 4
of Annex B. The IPTV STB should conform to this in order to get the software update.
4.1.8 Sl No. 3 of Annex B Specifies the signaling and transport of TV Anytime Meta data describing both Content on Demand as well as Live services delivered over an always on bi-directional IP
Networks. The capability to use this information to generate Broadband Content Guide should be
an optional requirement for the IPTV STB.
4.1.9 Clause 10 of Sl No. 1 of Annex B specifies Content Download Services (CDSs). CDSs provide
the download of content items to a local storage of the IPTV STB via a broadband IP connection.
Two types of services are supported: push download services where the distribution decision is
taken by the service provider (without explicit request from the user) and pull download services
where the download is requested by the user. If a STB is equipped with appropriate local storage,
it could use this service for content downloading.
4.1.10 Annex E of Sl No. 1 of Annex B defines an optional protocol for Application Layer FEC (AL-
FEC) protection of streaming media for DVB-IPTV services carried over RTP transport. If this
option is used at the sending end, the STB should have the capability to decode this FEC.
4.1.11 Annex F of Sl No. 1 of Annex B defines an optional re-transmission mechanism (RET) to
provide for protection against packet loss of DVB-IPTV services carried over RTP transport. It
specifies the mechanism to provide immediate FeedBack (FB) towards the network using RTCP
and how to retransmit the missing packets.
4.1.12 In a scenario where the Servers at the transmitting end has so many options, there has to be a
means for the Server to find out the configurations and the capabilities of the receiving devices at
the consumers premises before exercising those options. This is the function of the Remote
Management System (RMS) and the Firmware Update Service (FUS) described in Sl No. 4 of
Annex B. Remote Management is the ability of a server entity outside the home environment to
monitor and configure the devices within the home and covers provisioning and assurance tasks. It
optionally includes firmware updates to the equipment.
4.1.13 Conditional Access: Specific support for Conditional access or Content Protection is out of
scope of this ETSI standard as given in Sl No. 1 of Annex B.
