Windowing
From Wikipedia, the free encyclopedia
[edit] In broadcasting
In Broadcasting, windowing consists of exploiting the different windows of transmission available for a content in an order that will create the maximum revenue to the copyright holder.
For example: a film comes out for general release, then its exploitation is sold to the pay per view Channels to broadcast, then they are released for rent, then released to buy on DVD, then released on satellite TV as part of a pay offer, then the rights are sold to the free-to-air television networks...
All these stages can be reversed or exchanged depending on constraints such as laws or copyright infringement fears. The choice to skip or to change the order is decided by the potential of a content to be sold effectively in one window.
For example, if a movie is expected to flop if released in cinemas, studios are faced with the need to decide whether to invest more in the film's marketing and take a risk or to release it immediately to rent and DVDs straightaway.
[edit] In Networking
Windowing in networking means the quantity of data segments which is measured in bytes that a machine can transmit/send on the network without receiving an acknowledgement.
Part of the flow control process, windowing determines the amount of data that can be transmitted at one time, before the destination responds with an acknowledgment. After a host transmits the window-sized number of bytes, the host must receive an acknowledgment that the data has been received before it can send any more data. For example, if the window size is 1, each byte must be acknowledged before the next byte are sent.
[edit] In signal processing
In signal processing, windowing refers to the application of a window function to a signal.
