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.

Multiplexing an ASI Stream The Main advantage of multiplexing is the capability to create your own channel map add scrambling and other information to the incoming stream. Always take in consideration the data rate capability for processing this stream.

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. QAM Modulation: Quadrature Amplitude Modulation The Beauty of the Program Capacity of 1 QAM 256 Channel = 38.8 Mb/s* In the world of MPEG-2 a HD Program should run at approximately 15 Mb/s SD programming approximately 4 Mb/s (x=HD programs; y=SD programs) 15(x) + 4(y) < 38.8 *Mb/s – Megabit per second (unit of measure of data transfer HD Program HD Program SD Program 2 HD and 1 SD can be digitally muxed and modulated on a single 256 QAM channel HD Program HD Program HD Program HD Program SD Program SD Program 4 HD and 2 SD can be digitally muxed and modulated on a single 256 QAM channel (34.0 Mbit) “Programs” vs. “Channels” Understand the difference Bit rate of a Program High Definition (HD) vs. Standard Definition (SD) Recommended HD – 15 Mb/s MPEG2; SD – 4Mb/s MPEG 2 Recommended HD – 7.5 Mb/s MPEG4; SD – 1.5Mb/s MPEG 4 Capacity of a Channel 256 QAM = 38.8 Mb/s or 64 QAM = 28.8 Mb/s Two most popular modulation techniques CATV QAM Data Rates Types of QAM Modulators ASI QAM modulator Edge QAM modulator • • • • • • • • • ASI input MPTS & SPTS 38.8 Mb maximum Single QAM Channel IP input MPTS & SPTS GigE Capability Low cost Redundancy From of 4 to over 250 Channels 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. VOD using unicast in a broadband network. IPTV ??? OR IP STREAMING???

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.
