Change in the concept (Web 2.0)

Old concept – One way communication of media. No dialogue or way of taking part in the production of the content.

New concept – Two way collaborative content and media production and consumption. Audience actively takes part in the creation of the media. Feeling of commitment. Sharing and interacting in real time.

Video on demand

Allows users to select and watch video content on demand depending upon his convenience of time.

Provide the user with a large subset of  functionality including pause, fast forward, fast rewind, slow forward, jump to previous/future frame etc

Video hosting

A video hosting service allows individuals to upload video clips on internet website. The video host will then store the video on its server, and show the individual different types of code to allow others to view this video. The website, mainly used as the video hosting website, is usually called the video sharing website

Why Youtube didn’t existed earlier?

Streaming server costs were very high say 10 years back

Number of internet users were very limited Internet was not considered as a primary

means of communication User’s bandwidth was very less as compared

to today’s bandwidth

Purpose of video hosts (for users)

Save on bandwidth costs, often eliminating costs entirely

Creating a common place Make a hassle-free experience, where uploading a

video and streaming or embedding would normally require advanced programming knowledge. It is now commonly achieved through a web browser, with little or no programming experience.

Business models for video on demand

For free services the main source of revenue is by advertising on the site for ex Youtube

For satellite channels , the main source of revenues comes from subscriptions and advertising mainly

Advertising

Video on demand sites have advertisements flashing on the homepage along with the video

There are different subscriptions rates depending upon the number of ads as well as the duration of the ads on youtube

Example

Why people advertise on Youtube?

Youtube is currently the 2nd most visited site in the world right behind google

It means that there are millions of people visiting Youtube everyday and the scope of reaching them is huge....

Ways to advertise on Youtube

Through google Self-Managed Advertising (AdWords) Managed Accounts Through youtube Self-Managed Advertising (Promoted Videos) YouTube Direct Ad Sales

Competition base

Users visiting the sites The content available on the site

Potential threats

Copyright/piracy issue Upload of inappropriate contents Advertiser’s bargaining power – many sites

are available (Youtube, metacafe etc.) Various audio/video/image formats to support

(e.g. metacafe doesn’t support .asf )

Latest in video hosting (on demand to live streaming)

A mobile live streaming software called QIK allows the users to upload videos from their cell phones to the internet. The videos will then be stored online and can be shared to various social networking sites like Twitter, Facebook and YouTube. Videos will be stored on the servers and can be watched from both the mobile devices and the website.

Bambuser

Stream live video from mobile/webcam using 3G /WiFi network

Interact and communicate through web to mobile chat

Geo tagging enabled via cell-id or GPS

Advantage of Bambuser over Qik

Lower latency due to superior technical approaches

Streaming both from computer and mobile Stream videos from mobile to Facebook wall

How it works

Install the application on your mobile and use instead of your normal video capturing tool

The application uses the networks (EDGE, GPRS, 3G or WiFi) to transmit the video data from bambuser servers to the web

Needs operating systems like windows, Symbian S60, Mac OSx.

Challenge and approach

Challenge – poor mobile network Approach – transmit as much as data

possible and simply skip the data that can’t get through the networks and save it for later. Data dropped during broadcast is uploaded afterwards the video is completed and is provided on demand.

Business Model
