摘要： An image capture apparatus generates video data from captured images, and generates a video PES (packetized elementary stream) from the video data. The image capture apparatus converts the video PES into a MPEG-2 program stream, and converts the video PES into a MPEG-2 transport stream. The image capture apparatus records the MPEG-2 program stream on a random-access recording medium, and transmits the MPEG-2 transport stream to an external device. The conversion from the video PES into the MPEG-2 program stream and the conversion from the video PES into the MPEG-2 transport stream are performed in parallel thereby enabling the image capture apparatus to perform the recording of the MPEG-2 program stream and the transmission of the MPEG-2 transport stream in parallel.

摘要： When input data is written into or read out from a plurality of memories, operations of the plurality of memories are controlled in a manner such that, as for data which is read out from a predetermined memory among a plurality of memories each of which can store the input data, the data stored in the other memory is set to the read data from the predetermined memory. By virtue of this construction, even when the read data is uncorrectable data, the data with a higher correlation can be read out and a reproduction signal of a higher quality can be obtained.
