The resulting output is super continuum that is widely broadened to a wavelength band of 1400 nm to 1750 nm and is chirped to a linear characteristic.

An interface device for connecting to and retrieving data from a remote computer system, and method of compressing, decompressing and transferring data therefor. A user may set transfer constraints on the interface device. The interface device may be a web browser. The user selecting a web site requests data, normally image data from a remote computer system. The interface device includes a cache memory where generic objects may be stored. Each generic object corresponds to an original object in the requested data. Depending on the data transfer constraints, instead of retrieving the entire image, e.g., web page image, unaltered from the host system, a compact generic image is retrieved, initially, wherein generic objects are substituted for each corresponding original object. A pseudo-image is displayed, with the generic objects substituted for corresponding original objects. Subsequently received original objects may be substituted for generic objects as each original object is received.

The invention provides a method and a device for video concentration. The method comprises the following steps of obtaining a to-be-concentrated video and analyzing the to-be-concentrated video to obtain an analysis result, wherein the analysis result includes real-time number of people, kinematic velocity of crowd and consistent degree of movement of the crowd, which are corresponding to a video frame; determining a video fragment which needs to keep from the to-be-concentrated video according to the analysis result; and carrying out video coding on the video fragment which needs to keep to obtain concentration video data corresponding to the to-be-concentrated video. According to the method and the device, the real-time number of people, the kinematic velocity of the crowd and the consistent degree of movement of the crowd, which are corresponding to the video frame are obtained through a crowd analysis algorithm, and video concentration process is implemented according to the obtained relevant parameters of the crowd, so that the requirements for occasions with many people and continuous human movement, such as squares or metros, are met, the effective video concentration is carried out on monitoring videos in the occasions, a storage space needed for storing the monitoring videos in the occasions is saved, and the retrieval and playing time for the monitoring videos in the occasions is greatly shortened.
