Question

The challenge of rolling out television service is a process to be achieved using a number of steps. Answer the four parts below about television service rollouts..
Part 1: What are the required parameters needed to define the business model for a television service rollout?
Part 2: What would be some examples of requirements for service definition of a television service rollout?
Part 3: What might be some examples of equipment approval needed for a television service rollout?
Part 4: How might service assurance affect a television service rollout?

Answer 1

Part 1: Business model parameters needed for television roll out service

• Coder and decoders, they are required for several alternatives to compress and code programs .Latest standards like MPEG4 and WM-9 which are more flexible and efficient.
• Number of subscribers. IPTV requires costly infrastructures, however planning in metropolitan city would be much cheaper with higher density of population.
• Number of programs. We must define programs such way it must reach to all subscribers in all possible ways. The better the quality of the image is the more bandwidth is required.
• Multicast and unicast. The higher the proportion of unicast services, the more the resources and bandwidth the network requires. IP television generates multicast traffic, while video on demand services and internet access generates uni-combination traffics.

PART II: EXAMPLES OF REQUIRMENT FOR SERVICE DEFINATION OF A TELEVISION SERVICE ROLLOUT

• Define the business model. Determine key parameters based on market and competitors and design business plan different from other service providers.
• Architectonic design. Defining network elements including the contribution side and access network.
• Service definition. Definition must be based on size, coder and decoder standard, frame formats, encapsulations, and video profiles.
• Equipment approval. Once plan is ready, we need to determine network nodes, devices based on budget.
• Network commissioning. Engineers must monitor network performance and traffic, based on they can define multi cast nodes which will route the quality performance.
• Service Provision. Applications installed to check end-to-end performance and the capability of the network.
• Service assurance. Big measured need to be taken to trouble shoot and provide be service as per service user’s requirement.

PART III: EXAMPLES OF EQUIPMENT APPROVAL NEEDED FOR A TELEVISION SERVICE ROLLOUT

• Cable, Ethernet, Wireless, and Fiber, the cost to bandwidth ratio are the common selection criteria
• Focus to be maintained on digital provision.They must guarantee a minimum of 6Mbit/s to support one TV channel.
• Optical access. Now a days Fibre is the best media to deliver higher bandwidth. FTTP, is based on PON or Active Ethernet and can deliver around 100 Mbit/s to each subscriber.
• Servers. The necessary servers that are required must be clearly selected to ensure proper functioning of the system
• Network nodes and devices. It is necessary to select the right network nodes and devices that best fits the technical requirement, available budget.

PART IV: HOW SERVICE ASSURANCE AFFECT TELEVISION SERVICE ROLLOUT

• Content Faults. Assessment of the video quality and to find out the causes of the malfunction
• Network Impairments. IPTV applications use a transport and distribution net-work which cause traffic conditions may cause contention that produce packet loss, delays and jitter.
• Transaction Impairments. IPTV relay on proto-cols like IGMP to manage the IPTV channel zapping and RTSP to control de video streaming on VoD. Both may suffer of delay or no functionality at all.
• Transport Events. The transport, based on MPEG TS or RTP, is fundamental to distribute, synchronize, and decode the audio-visual streams.
