A wireless communication terminal (100, 200), comprising: an antenna unit (104, 204) including a narrow-directional antenna (106, 206) configured to transmit or receive video data of one frame in a one-frame period through a set of communication paths each being a high-speed transmission channel in which the narrow-directional antenna (106, 206) is used; a processing unit (107, 207) configured to process the video data transmitted or received through the narrow-directional antenna (106, 206); and a control unit (101, 201) configured, during the same one-frame period, to: - select a first communication path from a plurality of communication paths at a beginning of a first slot in the one-frame period, - cause the antenna unit (104, 204) to transmit or receive the video data of the one frame through the first communication path during the first slot, - repeat following steps a) and b) for n=2 up to an N-th slot within the one-frame period, wherein N≥2 is a number of slots within the one-frame period: - a) select an n-th communication path from the plurality of communication paths, - wherein the n-th communication path is different from any previously selected communication path(s), - wherein the n-th communication path is selected at a beginning of an n-th slot in the one-frame period, - b) cause the antenna unit (104, 204) to transmit or receive same video data as all or some of the video data transmitted or received through any previously selected communication path(s) through the n-th communication path, and - update, at the end of the N-th slot within the one-frame period, a communication path table, wherein the communication path table is a table including communication path information for each of the N slots. an antenna unit (104, 204) including a narrow-directional antenna (106, 206) configured to transmit or receive video data of one frame in a one-frame period through a set of communication paths each being a high-speed transmission channel in which the narrow-directional antenna (106, 206) is used;
