PART 2 PRODUCTS
2.1 GENERAL
IPTV is received by the viewer through the technologies used for
computer networks.IPTV is often provided in conjunction with Video on
Demand and may be bundled with Internet services such as Web access
and VoIP. IPTV shall be supplied using the closed network infrastructure
(corporate LAN).
Using set-top boxes at end users, TV channels shall be streamed to users
more efficiently than current coaxial cable.
Prefer separate switch for IPTV system .
Network shall allow higher speeds and multiple high definition TV
channels.
IPTV also allows significant opportunities to make the TV viewing
experience more interactive and personalized. The system may include an
interactive program guide that allows viewers to search for content by title
or actor¡¦s name, or a picture-in-picture functionality that allows them to
¡§channel surf¡¨ without leaving the program they¡¦re watching.
System may also include Video on Demand (Void) service allowing a
customer to browse an online movie catalogue, to watch trailers and to
select the movie he wants to watch.
2.2 EQUIPMENT AND MATERIALS
As with a digital satellite television system, an IPTV service
requires a video head end. This is the point in the network at
which broadcast TV and video on demand content is captured
and formatted for distribution over the IP
A head end takes each individual channel and encodes it into a
digital video format, like MPEG 4 which is the most prevalent
encoding standard for digital video.
After encoding, each channel is encapsulated into IP and sent
out over the project Local Area Network (LAN).User shall
6
install set top box before routing TV channels into his TV
receiver, or can use PC screen directly.
These channels are typically IP Unicast in which only the
selected channel(s) are distributed to the individual connected
users. Also multicast streams could be sent such as
advertisement broadcast service for lobbies, food courts and
open areas.
The IP TV services cabinet will be located in the satellite
headend in the project data center.
IPTV system is made up of following major elements:-
- Satellite and terrestrial reception Head End:-
- Streamer
- Encoder to encode channels to (Pay TV).
- Layer 3 switch and Gigabit Ethernet switch
- Access Network(By others)
- User network(By others)
- System management
N.B: contractor has to co-ordinate with project Local Area
Network for integration.
