Video distribution apparatus, distribution method, and recording medium

A method for a video distribution apparatus, comprising:

• generating a plurality of segment data and appending an index including time information of the segment data, wherein each of the plurality of the segment data corresponds to a predetermined time period of video data;
• receiving, from an external apparatus, an acquisition request which is for the segment data to which an index corresponding to a current time of the external apparatus is appended;
• and
• transmitting, to the external apparatus, the segment data for the acquisition request received by a acquisition reception unit,
• wherein in the generation of the segment data, in a case where, after transmitting a first segment data, the reception unit receives from the external apparatus an acquisition request for a third segment data to be generated without receiving an acquisition request for a second segment data already generated subsequent to the first segment data and before the third segment data, image data included in the second segment data is not changed and time information included in an index appended to the second segment data is changed to time information corresponding to the third segment data to update the second segment data as the third segment data, and
• wherein the second segment data updated as the third segment data is transmitted to the external apparatus in response to the acquisition request for the third segment data.

A computer-readable non-transitory recording medium storing a program for causing a computer to function as:

• a generation unit configured to generate a plurality of segment data and to append an index including time information of the segment data, wherein each of the plurality of the segment data corresponds to a predetermined time period of video data;
• a reception unit configured to receive, from an external apparatus, an acquisition request for the segment data to which an index corresponding to a current time of the external apparatus is appended;
• and
• a transmission unit configured to transmit, to the external apparatus, the segment data for the acquisition request received by the reception unit,
• wherein in a case where, after the transmission unit transmits a first segment data, the reception unit receives from the external apparatus an acquisition request for a third segment data to be generated without receiving an acquisition request for a second segment data already generated subsequent to the first segment data and before the third segment data, the generation unit is configured to not change image data included in the second segment data and to change time information included in an index appended to the second segment data to time information corresponding to the third segment data to update the second segment data as the third segment data, and
• wherein the transmission unit transmits the second segment data updated as the third segment data to the external apparatus in response to the acquisition request for the third segment data.
