Abstract
Abstract The present invention provides a method and a system which provide a plurality of compressed presentations for each frame of the original video signal, each presentation provided according to a different bit-rate, wherein the transmitting system selects from the compressed presentations a presentation, which is most suitable for the bit-rate, currently available over the transmission line and transmits it.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
A method for providing and managing a real time, variable bit-rate, compressed video broadcast signal to be transmitted over a variable bit-rate transmission line, the transmission line being characterized by a maximal bit-rate value and a minimal bit-rate value, the method comprising the steps of: A. converting a video signal into a group of at least two compressed frame-sets, each said frame-set compressed according to a different bit-rate value, said bit-rate values being no greater than said maximal bit-rate value, each said compressed frame-set including the same group of pictures (GOP) arrangement; B. detecting the available bit-rate value, currently available over said transmission line; C. selecting one of said compressed frame-sets, wherein said bit-rate value of said selected compressed frame-set is not higher than said available bit-rate value; D. selecting a GOP of said selected compressed frame-set as output; and E. repeating said steps B-D in order to select the next GOP.
Claim 2
Independent Claim
152 words
A method for providing and managing a real time, variable bit-rate, compressed video broadcast signal to be transmitted over a variable bit-rate transmission line, the transmission line being characterized by a maximal bit-rate value and a minimal bit-rate value, the method comprising the steps of: A. converting a video signal into a group of at least two compressed frame-sets, each said frame-set compressed according to a different bit-rate value, said bit-rate values being no greater than said maximal bit-rate value, each said compressed frame-set including the same group of pictures (GOP) arrangement; B. detecting the available bit-rate value, currently available over said transmission line; C. selecting one of said compressed frame-sets, wherein said bit-rate value of said selected compressed frame-set is not higher than said available bit-rate value; D. selecting a GOP of said selected compressed frame-set as output; and E. repeating said steps B-D in order to select the next GOP.
Claim 3
Dependent Claim
18 words
The method according to claim 1 further comprising the step of transmitting said GOP over said transmission line.
Claim 4
Independent Claim
160 words
A system for providing and managing a real time, variable bit-rate, compressed video broadcast signal, the system being connected on input to a video source and on output to a transmitter which is further connected to a variable bit-rate transmission line, the transmission line being characterized by a maximal bit-rate value and a minimal bit-rate value, the system comprising: a video encoder connected to said video source for compressing a video signal received from said video source into at least two compressed frame-sets, each said frame-set being compressed according to a different bit-rate value; and a controller connected to said video encoder and to said transmitter, for receiving an available bit-rate value from said transmitter, for selecting one of said compressed frame-sets, for selecting a group of frames (GOP) from said selected compressed frame-set and for providing said selected GOP to said transmitter, wherein the bit-rate value of said selected compressed frame-set is not greater than said available bit-rate value.
Claim 5
Independent Claim
160 words
A system for providing and managing a real time, variable bit-rate, compressed video broadcast signal, the system being connected on input to a video source and on output to a transmitter which is further connected to a variable bit-rate transmission line, the transmission line being characterized by a maximal bit-rate value and a minimal bit-rate value, the system comprising: a video encoder connected to said video source for compressing a video signal received from said video source into at least two compressed frame-sets, each said frame-set being compressed according to a different bit-rate value; and a controller connected to said video encoder and to said transmitter, for receiving an available bit-rate value from said transmitter, for selecting one of said compressed frame-sets, for selecting a group of frames (GOP) from said selected compressed frame-set and for providing said selected GOP to said transmitter, wherein the bit-rate value of said selected compressed frame-set is not greater than said available bit-rate value.
