"Video on demand (display) (VOD) are systems which allow users to select and watch/ listen to video or audio content when they choose to, rather than having to watch at a specific broadcast time. IPTV technology is often used to bring video on demand to televisions and personal computers." [Video on demand. Wikipedia]
The network diagram example "VoD architecture in a NVR enviroment" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computers and
Communications solution from the Illustration area of ConceptDraw Solution Park.

This interactive voice response (IVR) diagram sample depicts the architecture of IVR systems. It was designed on the base of the Wikimedia Commons file: IVR-Systemarchitektur.png. [commons.wikimedia.org/ wiki/ File:IVR-Systemarchitektur.png]

"DTMF decoding and speech recognition are used to interpret the caller's response to voice prompts. DTMF tones are entered via the telephone keypad. ...
Other technologies include using text-to-speech (TTS) to speak complex and dynamic information, such as e-mails, news reports or weather information. TTS is computer generated synthesized speech that is no longer the robotic voice traditionally associated with computers. Real voices create the speech in fragments that are spliced together (concatenated) and smoothed before being played to the caller.
An IVR can be deployed in several ways:
1. Equipment installed on the customer premises.
2. Equipment installed in the PSTN (public switched telephone network).
3. Application service provider (ASP) / hosted IVR.
IVR can be used to provide a more sophisticated voice mail experience to the caller. ...
An automatic call distributor (ACD) is often the first point of contact when calling many larger businesses. ...
IVR call flows are created in a variety of ways. A traditional IVR depended upon proprietary programming or scripting languages, whereas modern IVR applications are generated in a similar way to Web pages, using standards such as VoiceXML, CCXML, SRGS and SSML. ...
In telecommunications, an audio response unit (ARU) is a device that provides synthesized voice responses to DTMF keypresses by processing calls based on (a) the call-originator input, (b) information received from a database, and (c) information in the incoming call, such as the time of day.
ARUs increase the number of information calls handled and provide consistent quality in information retrieval." [Interactive voice response. Wikipedia]
The IVR diagram example "IVR systems architecture" was designed using ConceptDraw PRO diagramming and vector drawing software extended with the Interactive Voice Response Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

"Microsoft Azure (formerly Windows Azure before 25 March 2014) is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying and managing applications and services through a global network of Microsoft-managed datacenters. It provides both PaaS and IaaS services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems."

"In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed to not be secure or trusted. Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls are a software appliance running on general purpose hardware or hardware-based firewall computer appliances that filter traffic between two or more networks. Host-based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine. Firewall appliances may also offer other functionality to the internal network they protect such as acting as a DHCP or VPN server for that network." [Firewall (computing). Wikipedia]

"Home automation is the residential extension of building automation and involves the control and automation of lighting, heating, ventilation, air conditioning (HVAC), appliances, and security. Modern systems generally consist of switches and sensors connected to a central hub sometimes called a "gateway" from which the system is controlled with a user interface that is interacted either with a wall-mounted terminal, mobile phone software, tablet computer or a web interface."
