Abstract:- The explosive growth of Media applications and services has blurred a clear distinction between producers and consumers of media ttoday. End users are playing both roles at different times as there are many opportunities and potentially significant rewards for successful media applications and seamless services. In fact, end users are also producing media at a higher rate than consuming it, Facebook reports more than 300 million photos are uploaded every day. YouTube claims100 hours of video are uploaded every minute. Some interesting facts on online video trends and Internet Marketing statistics are:
• Viewers of online video will hit 500 million
• Over half the population and 70% of internet users will watch
• Mobile video will reach over 100 million viewers
• Smartphone’s video views over 75 million
Other interesting stats
• ~75% of home sellers will list with an agent that does video, but only 12% of agents have a YouTube account.
• YouTube has over 1000 million monthly unique visitors with over 4 billion video hours being watched
• 35% of YouTube traffic

• YouTube traffic from mobile devices tripled in 2012-2013 While there is great appetite for online content and the services and applications it generates there are a number of challenges—or gaps—in their play.
Most important gaps are:
1. Uninterrupted multimedia Support across devices:- New devices are constantly becoming available and users are more and more likely to be accessing applications and services from multiple devices. Only considering mobile devices, the number of mobile connected devices will exceed the world’s population in 2013, and by2017t herewillbe1.4 devices per capita worldwide .As the number and types of devices being connected in the home increase, it is creating an environment with products from a mix of manufacturers where there are more opportunities for device to device interaction. Given this trend, it is imperative that companies address the issue of seamless interoperability and support across devices in their products or risk being relegated to irrelevance.
2. Start-up latency: Many studies have concluded that video stalling in mobile networks has the largest impact on the user engagement and quality of experience across all types of video content. It seems that while consumers will settle for low resolution videos on smaller screens, they are usually very dissatisfied with stalls. We believe that video stalling is the most significant quality measure of video viewing experience. Traditionally stalling issues were treated by increasing the bandwidth (kbps) allotted for the video transaction. However, as networks get more congested and video content becomes more prevalent, it is harder to prevent the conditions that cause stalling. It is also interesting to explore whether the actual bandwidth is allocated appropriately and if parameters other than the allocated bandwidth have any effect on video stalling.80% of users quit videos within 10 seconds if they see more than 3 stalls 12 .
3. Distributed across Locations: A consequence of the abundance of media services, choices, and activities is that content is becoming highly distributed across a large number of locations. It is important for the end users to be able to find and access the content they require, or simply desire, without undue effort. The idea is to reduce the friction in content discovery and delivery so the end user stays engaged. Without this mechanism in place, the end user may be forced to exit the application and use another application or service to find what they need. Allowing users to centrally manage and authorize access to multiple online services as well as access content on personal storage in the home is one key way of breaking down content silos. The good news is that this is an area that is highly visible and valuable to end users, so there is a potential for significant value for companies that are able to provide good solutions for Distributed contents.
4. Flawless Media experience through Analytics: Reporting and analytics provide an opportunity to understand how the multimedia application or multimedia services are actually being used in practices. In order to improve or optimize anything, it must be measured, so having some data collection as part of the application or service is an important ingredient. Using data collected with adherence to appropriate privacy policies can result in significant insight that would be difficult to predict while still protecting the privacy of individual’s. This type of anonymous data can help identity which device is popular, which use cases are popular, how many devices a typical user has, and which feature users are not using or using most, to mention just a few. The data can also help operators to better understand the environment’s in which their products and services operate. In order to keep their product competitive and grow in new areas, companies need to take advantages of the insights that reporting and analytics can offer.
5. Video Classification and Adaptive QoP/QoS : With the development of heterogeneous networks and video coding standards, multiresolution video applications over networks become important. It is critical to ensure the service quality of the network for time-sensitive video services. Worldwide Interoperability for high available network bandwidth is a good candidate for delivering video signals because through LTE/5G the delivery quality based on the quality-of-service (QoS) setting can be guaranteed. The selection of suitable QoS parameters is, however, not trivial for service users. Instead, what a video service user really concerns with is the video quality of presentation (QoP) which includes the video resolution, the fidelity, and the frame rate. QoP is a user based definition of quality to measure for the ability to satisfy human needs. Experiments used QoP to evaluate the overall subjective quality of multimedia presentations at receiver end, where QoP has defined as two perceptual abilities of information assimilation and the level of enjoyment 3 . Considering user perception to perceive information or just enjoy the game when he/she picks up a sports game, treat QoP as two metrics of information metrics (QoPIM) and entertainment (QoPEnt)
6. Subjective Video Quality of available devices Subjectively perceived video quality is a critical factor when adopting new video applications. When video is used in mobile networks the most important requirements are related to low bitrates, framerates and the screen size of mobile device. Time-varying quality has a definite impact on human subjective judgments of quality, and this impact is a function of the frequency of occurrence of significant distortion changes and of the differences in quality between segments. Humans seemingly prefer longer freezes over shorter ones – this is not terribly surprising since choppy video playback is not pleasing at all. However, what is surprising about the frame-freeze distortion is that humans appear to be far more forgiving of lost segments than they are of choppy quality. This has interesting implications for those supplying real-time video delivery. It is also prudent to note that while choppy playback is the worst offender, lost segments star to matter relative to small reductions in choppiness. Further, this preference is dependent upon the content being displayed. It would be interesting to study whether the same results hold true when viewing sports – a viewer may prefer choppy playback in this case as opposed to him missing out on the footage 6 .
The sky rocketing growth of media applications and services in recent years is showing no signs of slowing. Cisco and Ericsson predict video traffic will account for about 70 percent of all consumer internet traffic by 2017, up about 60 percent from 2012. For mobile, video accounted for more than half of mobile data traffic in 2012 and will grow to three fourth of all mobile data by 2017 78 . There is no surprise for so much expansion in the use of media—it helps increase engagement and convert the story much more efficiently. Today, as multiple devices such as tablet computers and ultra-light laptops and smartphones make watching video ever easier and more accessible, viewing sets records every time Score or others measure it As is often said, a picture is worth millions words, and according to Dr. James McQuivey of Forrester Research, a minute of video is worth 1.8 million words 9.
Media applications and services today are expected to provide rich user experience which include various different combinations of multimedia (image, video, audio) capturing, media browsing, searching, sharing, and viewing high quality multimedia across a range of devices. Even for the applications and services where audio/video, images, and videos are not primary focus, they often play an important role since media can enhance the overall experience dramatically. Given the importance of the media companies are finding new and inventive ways to introduce media application features in their products to increase the value to their customers. For example for a leading manufacturer of wireless routers have been increasingly embedding media servers across product lines to allow their users to share devices throughout the home. In doing so, the router can become the media hub at home and play a much more visible role for the customer. People are also spending more and more time online using a wide range of value added services to access commercial content as well as view and share user generated content with friends and family. It’s easy for people to get involved in an increasing number of online services as the different social groups of which they are members may user different services. The growth in the availability of the connected devices capable of high quality media experience is also providing more outlets for end users to enjoy the content when and where ever they want. Operators have an opportunity to offer significant value to users of their product by providing integration with different complementary services people want to access. For example, some media applications are allowing user to link multiple online services accounts so the application can preset and display media from any of the services along with locally stored content in a seamless experience.
There are many opportunities and potentially significant rewards for successful media applications and seamless services. However its dynamic fast faced environment that is not the simple and presents a set of challenges for deploying a successful solution. Let’s discuss about some of the gaps in more detail to provide key recommendations.
Conclusion: Audio and video traffic on the internet is growing at an exponential rate. In fact more than 50% of all mobile traffic is video and there are over 6,300 stations streaming audio content to users. All this takes up vast amounts of bandwidth and is congesting networks for mobile operators – who are also losing revenues to OTT services. Keeping pace with the explosive growth of video traffic on mobile devices, any HD solution should be focused on optimization of all video content. Addressing these features predominantly help in reducing costs as operators are able to defer network expansion and are able to deliver Quality of Experience to the user and at the same time meet the demand of increasing video downloads.
