1. An electronic device, comprising:
circuitry configured to:
acquire at least one encryption key for a virtual meeting session with at least one participant device, wherein the electronic device includes a first meeting client to join or host the virtual meeting session and to communicate with a plurality of second meeting clients of the at least one participant device;
detect, in a duration of the virtual meeting session, an event based on analysis of a meeting-related content associated with the virtual meeting session, wherein the detected event corresponds to a first content transferred to the at least one participant device, via the first meeting client of the electronic device;
generate bitrate-specific versions of the first content;
determine a network bandwidth of a participant device of the at least one participant device in the duration of the virtual meeting session;
select a bitrate-specific version of the generated bitrate-specific versions based on the network bandwidth;
encrypt the selected bitrate-specific version of the first content by use of the at least one encryption key; and
transfer the encrypted bitrate-specific version of the first content to a meeting server,
wherein the meeting server transfers the encrypted bitrate-specific version of the first content to the at least one participant device.
