Specifically, the front-end EPG performs area division on an EPG page according to parameters carried by a play URL provided by the streaming server, that is, the height and width of each video after split-screen encoding, and divides a corresponding focus area for each video. Thereby dividing the EPG page into a plurality of focus areas of rnum columns and cnum rows. The default user selects the first focus area in the upper left corner and a focus box is displayed around the selected focus area, as shown in fig. 3. When the user moves to select the focus area through the up, down, left and right keys on the remote controller, the focus frame moves up, down, left and right. The right key is moved to the right by one focus area, the left key is moved to the left by one focus area, the up key is moved to the up by one focus area, and the down key is moved to the down by one focus area.
