Movie-on-Demand Delivery System

Pay attention; here's the outline for the first Embedded Linux Journal design project.

For our first project, we have a big one. It was inspired by a friend who works at a hotel. The hotel is looking into new systems that offer in-room movies. One proposal included a system that allows guests to select a movie for viewing and then gives them local control to view the movie over a six-hour period. In other words, much like a Tivo set-top box, they can pause, rewind and replay.

This differs from other systems that just allow them to queue up and watch one of the available copies of the movie from a central system. In addition to these movies, the system would provide typical in-hotel offerings including guest services, shopping, Internet access and TV. Typical second-tier menus would include billing, hotel facilities, phone numbers, TV channel listings, city guide and shopping.

Additional services could include music-on-demand, airline schedules, video conferencing, distance learning, message service, wake-up services and pay-per-view events. The design would need to be such that adding new services would be simple.

To get you started, the design needs to include:

  • A central server with all the movies on it. It would need accounting built-in to bill the guests and keep track of movie usage.

  • Fast Ethernet to the rooms.

  • Systems in the room with enough storage to store a movie and allow local control over its playback. Basically, like a Tivo with the addition of a ``delete/disable at a particular time'' time limit.

Questions that need to be addressed include:

  1. How many rooms could one server handle?

  2. How do you integrate multiple servers to handle a large hotel?

  3. How are movies supplied to in-hotel systems, and how does this system support that format?

  4. How are movie licensing and royalties handled?

  5. How long to download a movie to a room?

  6. Could you start playback before the download was complete?

  7. What is available commercially today and what does it cost?

  8. What other functionality can be added (local guides, ads, ...)?

Submit proposals by January 10, 2000. The best way to do this is send ASCII text to Our team will evaluate proposals as we receive them and display proposal status on our web site. The winning proposal will be announced in the April 2001 issue of Embedded Linux Journal.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
