APPLE - IPHONE 4
Transcript of APPLE - IPHONE 4
Mr. Yudel Arbella Lecturer: TELECOMMUNICATION Introduction Five years ago, Apple introduced the first iPhone to the telecommunication market. This revolutionary mobile phone allows users to make calls by simply pointing at a name or numbers. In addition, it is also able to sync all of the user's contacts from a PC, Mac or even internet service, (such as Google), with the use of its free iTunes software, which also connects users to its online store and allows them to purchase "apps" and music that enhances the usability of the iPhone even further. There is no doubt that the iPhone changed the way we communicate forever.
Today, since launching it's first iphone in 2007 Apple Inc. has 6 iPhone models. This Presentation will focused on the iPhone 4 which was released in June 24, 2010. The way we connect with each other The way we learn The way we see the world The Retina Display The 3.5 inch Retina display has 960 x 640 pixels or a pixel density of 326 pixels per inch, which is four times as many pixels as the iPhone 3GS and 78% of the pixels on an iPad. The iPhone Glass Screen The front and back glass have an oil-resistant coating that helps keep it clean The glass is also named Gorilla Glass which is the same technology used on windshields of helicopters and high-speed trains . Steel Frame and Antenna Encircling iPhone 4 is a highly finished stainless steel band made of a custom alloy that is forged to be five times stronger than standard steel. The A4 Processor iPhone 4 is powered by the new A4 processor Apple says provides exceptional processor for multi-tasking and graphic performance along with long battery life. The iSight Camera and flash iPhone 4 has a five megapixel autofocus camera with a 5x digital zoom, a backside illuminated sensor and built-in LED flash. You can now record and edit HD video using the tap to focus feature. But it didn't end there... FaceTime It introduced video chat on a phone to the world All you need is a WiFi connection This means you can be anywhere in the world! Make a FaceTime call from the United States to Australia! The Technology behind FaceTime is extensive! Here’s a short explanation on the role of each of the standard the iPhone 4 uses. H.264- it's one of the most prominent video compression standards in use today and is used by every major and minor video communications solution today, from the mobile video to desktop to room system to Telepresence system. it has AVC (advanced video coding) and SVC (scalable video coding) profiles – AVC profile is what is widely used and interoperable today, while SVC profile holds great promise once interoperability will be established. It already being used on the iPhone 4 . AAC Standard AAC- advanced audio coding standard. Widely used today in audio and video communications and has established the ability allow multiple devices work with each other(interoperability). It is used by iPhone 4 and other Apple devices. SIP Protocol SIP- Session Initiation Protocol – standard of IP Communications solutions, including both Voice and Video communications. Used by majority of video conferencing vendors, such as Cisco, Tandberg, Polycom, RADVISION and more. STUN PROTOCOL STUN- (Session Traversal Utilities for NAT) allows to map internal IP addressed behind the NAT to the external IP addresses. A Network address translation (NAT) allows a router to modify packets to allow for multiple devices to share a single public IP address. TURN PROTOCOL TURN- (Traversal Using Relay NAT) is used in rare cases where STUN doesn’t provide a solution. ICE PROTOCOL ICE- (Interactive Connectivity Establishment) is used as an umbrella standard utilizing STUN, TURN, uPnP(universal plug and play-allows devices to seamlessly discover each other's presence on the network and establish functional network services for data sharing) and others in order to find possible way to transfer the NAT and Firewall. Real-time Transport Protocol RTP- is used in Voice and Video over IP implementations to carry over real-time media and collecting of the statistics, such as jitter and latency, which in turn allows to implement better quality solutions. Today used by absolute majority IP voice and video vendors. Secure Real-time Transport Protocol SRTP- secure RTP communication supports encryption, message authentication and integrity. Widely used in both IP Video and Voice implementations. Let's see FaceTime in action! to Belize or from Belize But none of this would be possible without the Operating System The iOS 5 brought much more features 200+ to the iPhone 4 Some features that stood out included: Multitasking Folders Notifications New Camera app and photos New Reminders app You can now sync your iPhone to iTunes without plugging it into a PC or Mac.
