Below is the description of the layered architectural style. Layered architectural style: A layered system is formed dynamically, every one layer offers organization to the layers above to it and serving as an issue to the layer below. In some layered systems internal layers are moving away from all except from the connecting outside layer, beside particular limits definitely picked for the passage. The connectors are described by the traditions that evaluate how the layers will relate. Layered architectural style demonstrates the social event of related value inside locating into diverse layers that are stacked vertically on top of each other. The layered outline style has been portrayed as an issue pyramid of reuse where every one layer adds up to the commitments and consultations of the layer particularly underneath it. Helpfulness inside every one layer is joined by a regular part or commitment. Correspondence between layers is unequivocal and roughly coupled. Layer 2: This is the outer most layer of this architecture. In this user will interact directly to this layer for integrated home entertainment system. In this system user had an option to schedule the shows to record. This layer does not interact with other layers. Layer 1: This is the middle layer of this architecture. In this user will interact with external hardware such as Television, speakers, DVD player and gaming handsets. This layer interact will both layer 2 and layer 0. Layer 0: This is the internal layer of this architecture. In this layer the most prominent sections will be executed such as connecting to database, apps store authentication and authorizations. This layer interact will layer 1.

Usability 3 Y In this Integrated Home entertainment system, the user can select their user icon from start screen for easy play. Reliability 3 Y It displays the exact output. Performance 2 N Performance of the system will be slow as multiple functions are involved. Supportability 3 Y Security 1 N Safety 2 Y Availability 3 Y It supports all multimedia contents such as videos, images and games. The system is open to all users and intrusion may occur The data is secured until and unless if the subscriber subscribes for the channels. The user can select whenever he/she wishes to see the images, videos and can play games in the system. Maintainabilit y 3 Y The system has to be maintained and the software should be updated now and then frequently so that the system functions better. 11) Pattern: The idea is that there are external forces associated with certain problems that make them more easily solved using a particular approach. Every design also has a set of consequences that result from choosing that particular solution. Three part rule is followed in this, that include certain context, problem, solution. It involves in managing interfaces between objects in complex systems. For the Integrated Home Entertainment System, let us consider the design pattern. Name of the pattern: Delay response. Intent of the pattern: To avoid a player from being thrown off the game due to delay. Problem: Distinct delay between both action response and reflexes of players during the game. Solution: There are various techniques for decreasing delays though a number of these have their drawbacks and may not be applicable in all cases. In this event synchronization is not possible by the game itself. The customers himself may have to decide to play on servers in geographical closeness to themselves keeping in mind the end goal to reduce latencies or the servers might basically opt to drop customers with high latencies so as to abstain from avoid having to deal with the resulting problems. Nonetheless, these are hardly optimal solutions. Rather, games will frequently be outlined on account of lag compensation in mind. Participants and Collaborators: The two entities involved are Client and Server in this scenario. As customers are typically not permitted to characterize the basics of the game state but rather need to get it from the server. The principle task of the customer side compensation is to render the virtual world as precisely as possible. As overhauls come with delay and may even be dropped, it is sometime necessary for the customer to anticipate the stream of the game. Consequences: Lag causes various issues, for example, accurate rendering of the game state and hit detection. Numerous players that have a lower speed Internet connection are often not allowed or discouraged from playing with different players or servers that have a distant host server or have high latency to each other. Implementation: It is conceivable to reduce the view of lag through game outline. Techniques incorporate playing customer side animations as if the action took place on spot. To reducing or evacuating built-in timers on the host machine and uses cam transitions to hide warping
