Abstract: The invention relates to a method and a device for regulating the encoding bit rate of video images relative to a target image size). The images being subdivided into zones to be encoded, the complexity of encoding of each zone is distinguished among the zones, the zones to be encoded are classified according to a determined order of complexity, each zone is successively encoded according to the decreasing order of complexity, successively minimizing the estimated encoding error of each zone, the final size of each image relative to the target size and the bit rate of the sequence of video images. Application to the video encoding of images of video sequences, in particular to networked video surveillance.

Abstract: A method for monitoring video streams is proposed, which comprises: generating, by one or more source encoders, encoded multimedia content signals based on the encoding of monitored video streams respectively corresponding to one or more monitoring points along a workflow chain of a video broadcasting headend configured for one or more video channels broadcasted by the headend, and transmitting the encoded multimedia content signals to a remote monitoring device through a content distribution network.

Abstract: An apparatus for capturing video broadcasting signals comprises a plurality of capture channels, each channel producing respective video transport streams as inputs to a multi-channel virtualization module. Each channel comprises: an input interface powered by a low-noise power supply arranged to receive a respective modulated video broadcasting input signal within an input frequency band; a single input, dual output distribution amplifier arranged to produce first and second amplified input signals within a satellite broadcasting frequency band and within a cable and/or terrestrial broadcasting frequency band, respectively. A first tuner is configured to receive and downconvert the first amplified input signal to generate a first baseband signal; a second tuner is configured to receive and downconvert the second amplified input signal to generate a second baseband signal; and a demodulator is configured to receive the baseband signals as input and to generate the respective video transport stream.

Abstract: A method for processing a multimedia content previously digitally encoded into an audio-video stream and transmitted from a distribution platform for the purposes of on-demand transmission to a plurality of receiving terminals includes the following steps: applying a demultiplexing function to the audio-video stream, said function being arranged to generate at least one group of data streams; applying a transformation to each data stream; segmenting each data stream; storing the at least one group of segmented data streams in a memory; carrying out, only in response to a request issued by a receiving terminal among the plurality of receiving terminals, the following steps: selecting, on the basis of the request, at least one data stream of at least one group of stored data streams; and transmitting the at least one selected data stream to the receiving terminal that issued the request.
