Notable features include:

a.      Users can access the iTunes Store directly through Apple TV to rent movies and TV shows and stream audio and video podcasts. While the first iteration of the Apple TV could purchase content, the second generation lacks a hard drive, and thus cannot store purchased content. Instead, users would need to buy content on a computer and stream it to the Apple TV.
§  Apple TV can display photos from Flickr and MobileMe in a slide show, with automatic cross-dissolve transitions.
  • Netflix streaming integration was added in the September 2010 revision.
  • YouTube videos can be viewed directly on the Apple TV.
  • Rotten Tomatoes review syndication and ratings offered per title available for rent. Rotten Tomatoes account holders cannot login, so is not needed nor required, as no personalized options are available.

Each of the categories is configured by a parental control of "Show", "Hide" or "Ask" to prompt for a 4-digit preset code. In addition, movies, TV shows, music and podcasts can be restricted by rating.
Although Apple TV has a "Closed Captioning" setting, subtitles are not available for most iTunes content.
Apple TV’s main selling point today is its well-designed sleek hardware, responsive interface (consistent across all Apple Services), streaming ability from Computers and airplay experience (at minimum, play audio from Mac via airtunes). This is in addition to Apple’s perception of being a Cool Device Company. All their devices are cool because of successful marketing strategies and perception of consumers.

Media Aware IP Network

In this blog, I want to quickly introduce my audience to the term ‘Media Aware IP Network’. In addition to this, I will define the terms related to Media Aware IP Network. To make it more user friendly, I have used the Q/A format for this blog.

1. What is a Media-Aware IP Network??

Legacy Network built for data and voice is inadequate to deliver rich media. A robust network is required to deliver more interactive performance for media. This network should be able to make intelligent decisions on where the video packet needs to be routed to maximize picture quality and minimize bandwidth requirements.

Media-Aware OR Video-Aware Networks identify and qualify content based on user’s intent.

Media-Aware Network is also called with two other names -> Content Aware Network, Video Aware Network.

2. Why is there a need to have a Media- Aware IP Network today??

According to most surveys, we already know Video-on-demand, IPTV and Internet TV will constitute nearly 90% of all consumer traffic by 2012. Therefore there is a need to address this challenge by building a Video Aware Network that will deliver all types of media with a single end-to-end architecture. There is a lot of demand for more interactive content sharing on the internet along with increasing trend of rich media social networking.

3. Normal IP Network Vs. Media-Aware Network - Overview

 



     Figure 1. IP Networking Vs Content Aware Networking

4.       Who are Content Providers, Content Service Providers & Content Customers??

Content Providers are all News & Entertainment Companies including Studios.

For example -> NBC,  ABC News and 20th Century Fox are Content Providers.
Content Service Providers are all infrastructure providers for delivering Videos to the end-customers. For example -> Video on Demand Companies like Netflix, Amazon Video on Demand.
Content Service Providers collaborate with Hardware Manufacturers to deploy their Video on Demand Infrastructure.

Content Customers are subscribers of Netflix, Hulu and Amazon Video on Demand Services.

5. What is Content Aware Routing??

Content Routing is the mechanism of routing the request to the closer Server using the intelligence of the Network.

6. What is a Media Aware network element??

A Network Element parses RTP payload headers or the RTP payload and based on the content react routes the IP Packet.  A Network element can be a Hardware OR a Software component.

7. What is MediaNet ?? Who is offering these kind of Infrastructure solutions to Service Providers ?? Can you provide an example ??
A MediaNet is a media-aware Cisco IP Next-Generation Network (NGN), which deliver all types of media with a single end-to-end architecture.  With Medianet, the Service Providers can offer wide range of multimedia services like IPTV, VOD etc. with improved quality of experience.


Cisco is already working today to deliver MediaNet Infrastructure for the Service Providers. 
Here are unique advantages of Cisco offerings in this space.
• Provide a differentiated user experience with more content, control, and personalization
• Increase efficiency and reduce costs by collapsing operational silos
• Improve scalability by virtualizing content, infrastructure, and services, allowing operators to efficiently deliver more content to more subscribers
• Increase service velocity by allowing the launch of new services simultaneously in multiple markets or to national or transnational audiences
• Dramatically expand advertising opportunities and revenue models
