Abstract
An encoding apparatus includes an encoding unit for encoding input video data, a storage unit for storing the video data encoded by the encoding unit, a control unit for controlling the amount of video data which has a format including a vertical blanking interval output from the encoding unit in accordance with the amount of data stored in the storage unit, and a multiplexing unit for multiplexing additional data with the video data encoded by the encoding means during the vertical blanking period of the video data. Another encoding apparatus includes a first input unit for inputting first data, a second input unit for inputting second data, an encoding unit for encoding the first data input by the first input unit, a detection unit for detecting the amount of the second data input by the second input unit, a multiplexing unit for multiplexing the second data with the first data encoded by the encoding uit, and a control unit for controlling the multiplexing processing of the multiplexing unit in accordance with an output from the detection unit.
