FIELD: physics, communications.
SUBSTANCE: invention relates to multimedia transmission systems, specifically to methods and a device for acquiring services. Proposed is a service acquisition device which has a source coder configured to generate one or more channel switch video (CSV) signals, which is an independently decoded version of a low-resolution video for the selected channel in a received multiplex transmission and associated one or more multimedia signals, an error coder configured to code CSV signals and multimedia signals for formation of coded error blocks, and a linker configured to encapsulate coded error blocks into a multiplex transmission signal.
EFFECT: fast acquisition of a service and/or switching between services in multiplex transmission.
