Abstract: In situations where a receiver, rendering a content, switches from a first transport stream carrying that content to a second transport stream carrying that same content, artefacts may occur on the rendered content while transitioning between both transport streams. Considering transport stream data of a transport stream signal may be available at a nominal frequency higher than a frequency corresponding to the transport stream bitrate, there may be some periods of time during which no data is present in the transport stream signal. A salient idea is to switch from the first transport stream signal to the second transport stream signal in such periods during which there is no transport stream valid data in the first transport stream signal, allowing to minimize the risks of perceptible defects in the rendered content throughout the switching.
