IPTV Makes Channel Surfing More Like Web Surfing ? Nearly 7. 0% of us get our TV via one of the major cable providers. Satellite has carved out a good niche and grabs more than 2. If it’s strictly over the air, then hold your hand up as one of the 1. AT& T, Verizon, and other telecommunications (phone) companies (telcos) are making a huge effort to bring TV to the Internet and over fiber. There are some tremendous benefits to IPTV.
However, some interesting technical and business challenges must be dealt with, not to mention the fact that cable is fighting back. The IPTV services are essentially at parity with the cable companies even though their content offerings are still a bit below what the premier cable companies offer. The main difference is the pricing advantage that IPTV has over cable. The telcos need some clear, distinguishing factor to help them gain a stronger foothold in the pay- TV business. According to Mike Coward, CTO of Continuous Computing, two benefits could make the difference. All of the content is sent via fiber to the neighborhood DSLAMs (digital subscriber line access multiplexers).

At this point, the customer’s selected channel is picked out and sent to the set- top box (STB). Cable customers always get all of the content selected by the STB consumer. This is done now with a Ti.
Vo box or digital video recorder (DVR) at the subscriber’s home. Telcos can offer what might be called network personal video recorders (PVRs), where the stored video is on the carrier’s servers (for an extra charge). These options may be the differentiator the telcos need to succeed with TV. However, that’s not the same as Internet TV, which is what we call those You.

Named Broadband Space, the IPTV service is available at present for. This Frost & Sullivan research service entitled North American IPTV Services Market provides a discussion of the market for IPTV-based services and the set-top boxes. Online TV: how IPTV changes everything. Most new Blu-ray players and PVRs have some form of IPTV service on-board and. Catch-up programs like Yahoo7's Plus7 and.
Space, or Microsoft that viewers watch on their PCs. The telecom network is fiber to the neighborhood and a fast DSL line to the customer’s home for Internet access on the PC or IPTV. This diagram shows that IPTV also could be delivered over a cable network and could very well occur in the future. A hybrid STB that can accommodate IPTV, cable, or even digital broadcast over- the- air TV may be a necessity in some areas. AT& T’s U- verse system, which began in Texas, is now rolling out across the country in selected areas.
Fiber is run to the neighborhoods and terminates at a DSLAM that gives access to AT& T’s phone customers via the installed copper unshielded twisted pair (UTP) base. Using fast ADSL2 or VDSL2, the TV then is delivered to the customer’s TV set in compressed format. This full- blown fiber- tothe- home (FTTH) service offers TV, high- speed Internet service, and Vo.
IP. Downstream speed is 5. Mbits/s and upstream is 2.
Mbits/s, the fastest available to date. Fi. OS isn’t true IPTV, since it uses a delivery method similar to cable TV’s modulated RF system for TV, data, and other services. But rumors abound that Verizon will change to an all- IPTV system in the future.
DSL providers of Internet service have already hit the wall, so to speak, with data rates usually maxing out at 6 Mbits/s (slightly more in a few places). High- end DSL versions like VDSL2 do provide very high rates, but only over short distances. Top cable rates for ordinary service are faster, but cable companies have nearly hit the limit at about 2. Mbits/s with current systems and prices are high. Fiber is the only way up beyond this point.
So while it is expensive, you will begin to see more and more fiber in the future. TV demands it and consumers are pressing for faster downloads, uploads, and gaming capability. IPTV can provide that, but cable is clearly keeping up Continue on Page 2. IPTV HARDWAREA rear- view image of a typical IPTV STB provides the details on inputs and outputs (Fig. The Amino STB comes in a variety of configurations depending on the service provider and geographical location.
Some units also provide for composite, component, RGB, S- video, and other video formats. A USB 2. The video decoders are MPEG- 4 AVC/H. The box will also decode MPEG- 2 with resolutions to 7. Additionally, it handles protocols like Video on Demand (Vo. D) Real Time Streaming Protocol (RTSP) video session control and multicast with Internet Group Management Protocol (IGMP).
It can be configured for 4: 3 and 1. Both PAL 5. 0- Hz and NTSC 6. Hz outputs are available. Stereo and Dolby 5.
Other features include an IR remote control and HTML 4 browser with Java. Script. Circuitry inside the typical IPTV STB is very simple and often contained in a single large IC. The input usually goes through an RJ- 4. Ethernet port from the external cable TV or DSL broadband modem. This signal is then sent to the media processor chip that does all of the decryption, video decompression, and other protocol implementation. An example of such a chip is Sigma Design’s SMP8. Fig. High- performance graphics acceleration, multistandard audio decoding, advanced display- processing capabilities, and HDMI 1.
Powerful content security is ensured through a dedicated secure processor, onchip flash memory, and a range of digital rights management (DRM) engines for high- speed payload decryption. The SMP8. Gigabit Ethernet controller, dual USB 2. NAND flash controller, and IR and SATA controllers. In effect a multicore media processor, the SMP8. MHz MIPS 2.
CPU that enables crisp user interaction as well as a wider range of application- based features that enhance the “future- proofing” of this platform. A third MIPS processor manages all system security functions, including decryption and key generation.
The SMP8. 65. 4 also features a new DDR- 2 memory controller. It supports double- data- rate (DDR) memories up to 6. Mbits/s as well as an improved arbitration engine to maximize the efficiency of accesses.
Finally, the processor maintains software compatibility with the Sigma Multimedia Library to uniquely build on the proven performance and reliability of the earlier generation platforms. Sigma also recently announced a collaboration that will enable the Microsoft Mediaroom Internet Protocol Television and multimedia platform to operate on next- generation STBs using the Sigma SMP8. So. C. Thanks to the solution’s high- performance, cost- effective design, service providers will likely be able to offer innovative connected TV services, such as PC to TV photo and music sharing as well as DVR Anywhere, which gives consumers the flexibility to watch their recorded programs on any TV in their home.
Some STBs, especially in Europe, have built- in tuners so they can get over- the- air digital TV broadcasts, too. On the carrier side, a complete IPTV platform requires switches, packet processing blades, CPU cards, and high- availability software that can handle 1. G Ethernet speeds. One such example is Continuous Computing’s 1. Gigabit Traffic Management and Security Platform (Fig. At the heart of this platform, which is based on the Advanced Telecommunications Architecture (ATCA), is the Flex. Packet PP5.
It uses two Raza Microelectronics XLR7. For the computing part of the system, Continuous Computing offers its Flex- Compute ATCA- XE5. Intel Xeon processing board. The switching can be handled by one of Continuous Computing’s switches like the Flex. Core ATCAFM4. 0, an integrated 1. G Ethernet base fabric switching and management solution.
CABLE'S DOCSIS RESPONSECable continues its dominance by moving toward DOCSIS 3. This Cable. Labs standard has yet to be widely adopted, but it will gradually find its way into every cable head end and STB. It provides more flexible and scalable high- speed Internet service at least four times faster than current DOCSIS 2.
In addition, DOCSIS 3.
