Abstract:
1. A video data processing apparatus comprising: a reading unit configured to read a video data item from a video data file in response to a first control signal, and to read index data items from the video data file in response to a second control signal, the video data file including a video data part consisting of 1 to n video data items and an index part consisting of 1 to n index data items, wherein for each video data item there is a respective index data item consisting of a data length from a head position of the file to a head position of the respective video data item; a memory configured to store the index data items read by the reading unit; and a controller configured to control the reading unit by outputting the second control signal for reading the index data items consisting of the data length from the head position of the file to the head position of the respective video data item from the video data file in response to connection of a randomly accessible storage medium in which the video data file is recorded to the video data processing apparatus, wherein the controller is arranged to output the second control signal for reading the index data items consisting of the data length from the head position of the file to the head position of the respective video data item from the video data file before outputting the first control signal for reading the video data item from the video data file such that the memory stores in advance the index data items of the video data file prior to reproduction of video data; wherein the controller is configured to, in response to a request to execute a process to the video data file, read an index data item from the memory, and issue the first control signal to read a video data item indicated by the read index data item from the video data file with a designation of the video data item to be read.
