A system comprising cascaded standardized hot-pluggable transceiving units for providing a multiviewer functionality. A first layer comprises a plurality of transceiving units implementing a scaling functionality followed by a pre-positioning functionality. A second layer comprises a transceiving unit implementing a positioning functionality. Source video streams are scaled by the first layer, and further combined to generate primary mosaiced video streams. The primary mosaiced video streams are combined by the second layer to generate a secondary mosaiced video stream. Alternatively, the first layer comprises at least one transceiving unit only implementing the scaling functionality. Source video streams are scaled by the first layer to generate scaled video streams. The scaled video streams are combined by the second layer to generate a mosaiced video stream.

Cascaded standardized hot-pluggable transceiving units providing a multiviewer functionality

A standardized hot-pluggable transceiving unit implementing bandwidth optimization functionalities. The transceiving unit comprises a first connector receiving a signal comprising a source video payload. The transceiving unit comprises a processing unit performing a scaling of the source video payload. The scaling consists in generating a scaled video payload by applying a scaling ratio to the source video payload. The transceiving unit comprises a second connector outputting an IP flow transporting the scaled video payload. In an alternative bandwidth optimization implementation, the first connector receives a plurality of source IP flows each transporting a source video payload. The processing unit selects one among the plurality of source IP flows, and generates outbound IP packets of an outbound IP flow based on stored characteristics of the outbound IP flow. The outbound IP packets transporting the source video payload of the selected source IP flow are outputted by the second connector.

Cascaded standardized hot-pluggable transceiving units providing scaling and positioning functionalities

First and second IP flows corresponding to a first source are received. An SDI signal corresponding to the first source is generated based on a selected one of the simultaneously received first and second flows. Reception of one of the first and second flows is stopped, and the SDI signal is generated based on the remaining one of the first and second flows. A third IP flow transporting a payload corresponding to a second source is received, and a transition performed between first and second sources. An SDI signal corresponding to the second source is generated based on the third flow. Reception of the remaining one of the first and second flows is stopped, and a fourth IP flow corresponding to the second source is received. The SDI signal corresponding to the second source is generated based on a selected one of the simultaneously received third and fourth flows.
