MPEG-2 (Motion Picture Experts Group)
standard 2 is a compression standard for
digital television.
MPEG-2 compression enables digital
television broadcasters to transmit video
streams with higher resolution and audio
streams with higher quality sound while
using as little bandwidth as possible
H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is a standard for video compression, and is
currently one of the most commonly used formats for the recording, compression, and distribution of high
definition video. The final drafting work on the first version of the standard was completed in May 2003.
H.264/MPEG-4 AVC is a block-oriented motion-compensation based codec standard developed by the ITU-T Video Coding
Experts Group (VCEG) together with the International Organization for Standardization (ISO)/International Electrotechnical
Commission (IEC) and Moving Picture Experts Group (MPEG). It was the product of a partnership effort known as the Joint
Video Team (JVT). The ITU-T H.264 standard and the ISO/IEC MPEG-4 AVC standard (formally, ISO/IEC 14496-10 – MPEG4 Part 10, Advanced Video Coding) are jointly maintained so that they have identical technical content.
H.264 is perhaps best known as being one of the codec standards for Blu-ray Discs ; all Blu-ray Disc players must be able to
decode H.264. It is also widely used by streaming internet sources, such as videos from YouTube , and the iTunes Store, web
software such as the Adobe Flash Player and Microsoft Silverlight, broadcast services for DVB -broadcast satellite television
services, cable television services, and real-time videoconferencing.
HD/SDI and SD/SDI
Broadcast quality video – RAW
uncompressed, unencrypted digital video signals
Serial Digital Interface (SDI) is a standard for digital video transmission over coaxial cable . The
most common data speed is 270 megabits per second (Mbps) on SD/SDI or HD-SDI (1.45 Gbit/s).
Standard 75-ohm cable is used with BNC connectors.
ASI is a streaming data format which o carries an COMPRESSED MPEG Transport Stream
(MPEG TS).
*An ASI signal can carry one stream , also know as SPTS (single Program Transport stream) or
Multiple Program Transport Stream (MPTS) SD, HD or audio programs that are already
compressed.
not like an uncompressed SD-SDI(270 Mbit) or HD-SDI (1.45 Gbit). An ASI signal can be at
varying transmission speeds and is completely dependent on the user's setup requirements.
the ASI signal is the final product of video compression, either MPEG2 or MPEG4, ready for
transmission to a transmitter or microwave system or other device. Sometimes it is also
converted to fiber, RF or other types of transmission.
There are two transmission formats commonly used by the ASI interface: the 188 byte
format and the 204 byte format.
The 188 byte format is the more common ASI transport stream.

QAM Modulation:
Quadrature Amplitude Modulation
A method for imprinting digital signals onto a carrier for transportation from one place, such
as a cable headend, to another, such as a home. The advantage of QAM is the ability to
multiplex multiple programs on a standard 6 MHz channel. In a QAM 256 system 38.8 Mbit
of data can be transmitted. QAM-64 afforded about 28.85 Mbit per channel, but is more
tolerant of noise in the distribution system
Today most systems generally use 256-QAM modulation. Even though the technique is
called quadrature amplitude modulation, it also involves the use of "phase modulation.
What happens, loosely, is this: Digital bits are grouped into symbols, which are then
imprinted onto a carrier by manipulating two transmission characteristics: Amplitude
(power) and phase (frequency shape). The advantage of this dual modulation is the ability
to stuff twice as much information into the transmission channel, at the same time.

In the world of MPEG-2 a HD Program should run at approximately 15

The internet protocol (IP) [ is a packet-based-network transport protocol upon
which the internet is built. IP packets are encapsulated in lower, hardware-level
protocols for delivery over various networks (Ethernet, etc), and they
encapsulate higher transport level protocols for streaming and other
applications.
IP –Stream Source:
MPEG-TS Encaptulated in UDP/IP
Sending MPEG-transport stream packets over UDP is used extensively within the private networks of cable
companies to deliver MPEG transport streams throughout the system. For general delivery over the unmanaged
Internet without QoS (Quality of Service) guarantees, streaming protocols such as RTP may be used, but even
then, packets may be lost in delivery, resulting in artifacts in the media presentation.
Delivering TV and movie services over IP promised to revolutionize almost every component of the TV industry.
Just as the Internet changed how we ship, read the news and interact with others, television over IP could change
how we integrate TV entertainment into our daily lives.
Combining the Internet and protocols can create an entirely new and exciting experience for viewers and new
business opportunities for service providers. One key will be to maintain a high QoS across the entire network so
viewers never suffer from the limitations we see in Internet video.
What is IP Streaming :
MULTICASTING :
In multicasting, the sending side issues a stream of identically-addressed IP
packets, where the address identifies a multicast group participated by multiple
end users. Routers on the network replicate the stream as necessary and direct it
to the group's end users. Since the sending side must send only a single stream
of packets, the processing load on the server is low. And since the routers send
the stream only to clients that want it, overall network efficiency is maintained.
But multicasting is possible only if it is supported by all of the routers between
the sender and the recipients. Accordingly, multicasting requires the appropriate
network environment in order to succeed
MULTICASTING :
Broadcast video using multicast in a broadband
network.
UNICASTING :
With unicasting, the server issues a separate stream to each recipient,
addressing each IP packet with the address of its final destination. Since the
server must send separate packets for each final destination, the load on it
increases in proportion with the number of destinations. Greater bandwidth is
also required to handle the increased number of packets.
On the plus side, unicasting does not require multicast-capable routers and is
generally easier to implement
UNICASTING :
if this is MPEG-2 HD video, it could require as
much as 15Mb/s for each stream, or, in this
example, a total of 45MB/s. Clearly, when using
unicast protocol, network bandwidth
requirements can quickly become huge.

HOW TO TRANSCODE EFFICIENTLY:
IRD TRANSCODING :
As demand for more high definition (HD) programming increases, new
distribution architectures are being implemented with emerging
technology such as HD video processing, MPEG-4 AVC and advanced
modulation.
This commercial satellite receiver/transcoder, capable of transcoding
three MPEG-4 HD services and outputting three simultaneous MPEG-2
HD and standard definition (SD) services.
Server Transcoding Solutions:
The need for many transitions in codecs and bit rates throughout a video delivery chain can present
many challenges. Sencore’s TXS 3453 provides a high density, versatile answer to this problem by
providing H.264 and MPEG-2 compression engines that are independent of the incoming
compression type. The TXS 3453 ensures that your video will always be the correct format,
compression type and bit rate for up to 16 services per TXS regardless of consumer premise
equipment, IP network or last mile bandwidth constraints.
Digital Media Gateway:
Application Description:
Five MPEG-4 to MPEG-2 transcoding modules and one Gigabit IP Module or one ASI
input/output Module Support 10 channel of transcoding from MPEG-2 to H.264 or from
H.264 to MPEG2Applications: Content providers, CATV operators and IPTV network
