introduction

market forecast

Digital-video transmission has managed to creep into our lives. It is expected

that within the next few years, high-quality video will be distributed along with voice and data, in our offices, and homes.

A multimedia-streaming server helps to achieve controlled streaming of multimedia information over an enterprise network. The streaming server can receive data from various sources, including its own secondary storage. It consists of codecs to transform data, a mechanism to control the flow of data, and a mechanism to deliver this data over the network.

Network enterprises find the use of streaming in delivering corporate

communications very compelling due to cost savings in applications like on-site training, remote sales presentation, management broadcasts, etcetera.

Steve Balmer of Microsoft says, “There will be a day, I promise you, when every corporation will view it as a routine to communicate with its employees via streaming over the corporate intranet.”

networking computing e-mail poll, respondents were asked if they were

In a considering using broadcast video.

Answer Response (in percentage)

Yes, we are currently using it. 25 Yes, within six months. 12 Yes, in 12 to 24 months. 13 Yes, beyond 24 months. 24

The poll results indicate that companies are showing precipitous interest to use video-broadcast, with potential opportunities in streaming products.

Internet Traffic is expected to augment from 1 Million terabytes/month to 16M terabytes/month in the near future.

It is estimated that streaming server market will grow considerably from 64,000 units in 2001 to 212,000 in the next couple of years, approximately 300% increase (from Video Streaming Study by Anderson school at UCLA).

HP offers an optimum framework for multimedia streaming solutions in terms of performance as it has implemented the critical portion of RTP in the kernel. This is HP’s key differentiating factor in the multimedia streaming market.
