Abstract:
ATM cells are used to transmit information supplied in the form of a series of separate, identically structured entities each corresponding to a whole independently usable by a given application. Each entity is transmitted as cells whose information field is identically composed of modules of fixed position and fixed size. A first module constitutes a cell continuity index. A second module contains entity data to be transmitted. A final module is established by means of a B. C. H. block type error detector-corrector code. A transmitter and a receiver include apparatus for implementing the method between a source application and a destination application across an ATM network.
Abstract:
A method and apparatus for playing back a sequence of images from a run of component images successively supplied in digital form by a remote source to a receiver apparatus having the function of playing back the images of the sequence at a given rate, and in which each image constitutes an independent set that is received in the form of data trains. The apparatus includes verification that each received data train and each run of trains making up a set is valid, storing the most recently received valid set, reconstituting image signals from the most recently received valid set, and a clock for locally and independently generating clock signals for triggering visual reproduction of images as a function of circumstances.
