A method for transmitting video data, said method comprising: in a first electronic device: splitting each frame of said video data into a plurality of partial resolution layers, wherein each of said plurality of partial resolution layers comprises a base frame layer and one or more additional frame layers arranged in a form of a resolution pyramid, in a sequence that starts from a highest resolution layer to a lowest resolution layer, wherein a resolution value of said base frame layer is less than the resolution value of each of said one or more additional frame layers; and transmitting said base frame layer and said one or more additional frame layers of said frame of said video data to a second electronic device; wherein said one or more additional frame layers of said frame are transmitted to said second electronic device on a basis of priority information associated with said transmitted base frame layer of said frame, wherein the priority information comprises one or more user preferences provided by a user of the second electronic device via a user interface; wherein, in the second electronic device: the user interface displays thumbnail images corresponding to the base frame layers of the frames of video data and receives a selection of one or more of the thumbnail images from the user; in response to the selection, the priority information associated with the one or more base frame layers associated with the one or more thumbnail images is updated; and as the one or more additional frame layers associated with the one or more thumbnail images are received, the resolution of the one or more thumbnail images is increased. splitting each frame of said video data into a plurality of partial resolution layers, wherein each of said plurality of partial resolution layers comprises a base frame layer and one or more additional frame layers arranged in a form of a resolution pyramid, in a sequence that starts from a highest resolution layer to a lowest resolution layer, wherein a resolution value of said base frame layer is less than the resolution value of each of said one or more additional frame layers; and transmitting said base frame layer and said one or more additional frame layers of said frame of said video data to a second electronic device; wherein said one or more additional frame layers of said frame are transmitted to said second electronic device on a basis of priority information associated with said transmitted base frame layer of said frame, wherein the priority information comprises one or more user preferences provided by a user of the second electronic device via a user interface; wherein, in the second electronic device: the user interface displays thumbnail images corresponding to the base frame layers of the frames of video data and receives a selection of one or more of the thumbnail images from the user; in response to the selection, the priority information associated with the one or more base frame layers associated with the one or more thumbnail images is updated; and as the one or more additional frame layers associated with the one or more thumbnail images are received, the resolution of the one or more thumbnail images is increased. the user interface displays thumbnail images corresponding to the base frame layers of the frames of video data and receives a selection of one or more of the thumbnail images from the user; in response to the selection, the priority information associated with the one or more base frame layers associated with the one or more thumbnail images is updated; and as the one or more additional frame layers associated with the one or more thumbnail images are received, the resolution of the one or more thumbnail images is increased.
