Abstract:
1. An image capture apparatus comprising: a camera unit that generates video data from captured images; a video PES (packetized elementary stream) generating unit that generates a video PES from the video data generated by the camera unit; a first conversion unit that converts the video PES into a MPEG-2 program stream in a first mode; a second conversion unit that converts the video PES into a MPEG-2 transport stream in the first mode; a recording unit that records the MPEG-2 program stream on a random-access recording medium in the first mode; a communication unit that transmits the MPEG-2 transport stream to an external device in the first mode, and receives the MPEG-2 transport stream from the external device in a second mode, wherein a mode change between the first and second modes is initiated by a user of the image capture apparatus; a conversion determination unit that determines, according to a user instruction, whether a change of at least one of a preset number of pixels and frame rate of the received MPEG-2 transport stream is necessary in the second mode; and a decoding unit that decodes the received MPEG-2 transport stream into decoded video data, and changes at least one of the present number of pixels and frame rate of the decoded video data according to the user instruction in the second mode based on the determination result of the conversion determination unit, wherein, if the conversion determination unit determines that the change is necessary in the second mode: the decoding unit decodes the received MPEG-2 transport stream and changes at least one of the preset number of pixels and frame rate of the decoded video data; the video PES generating unit generates the video PES from the decoded video data of which at least one of the preset number of pixels and frame rate has been changed by the decoding unit; and the first conversion unit converts the video PES generated from the decoded video data into the MPEG-2 program stream enabling the recording unit to record the converted MPEG-2 program stream on the random-access recording medium, and wherein, if the conversion determination unit determines that the change is not necessary in the second mode: the second conversion unit inversely-converts the received MPEG-2 transport stream into the converted video PES, and the first conversion unit directly converts the converted video PES into the MPEG-2 program stream without decoding the converted video PES enabling the recording unit to record the converted MPEG-2 program stream on the random-access recording medium.
