Abstract
Waiting-for-transmission fragments that cannot be transmitted by a transmission unit due to the interruption of transmission by the transmission unit are stored. In accordance with the waiting-for-transmission fragments, a fragment to be transmitted prior to a first fragment including an intra-coded frame is eliminated from the waiting-for-transmission fragments. The transmission unit is controlled so that the first fragment is transmitted at the resumption of transmission.
Claims11
A transmission apparatus comprising:
- a division unit configured to divide video data into a fragment of one or more frames starting from an intra-coded frame and a fragment of one or more inter-coded frames;
- a transmission unit configured to transmit the fragment of one or more frames starting from an intra-coded frame and the fragment of one or more inter-coded frames;
- a storage unit configured to store waiting-for-transmission fragments that are not able to be transmitted by the transmission unit;
- an elimination unit configured to eliminate from the waiting-for-transmission fragments a fragment of one or more inter-coded frames to be transmitted prior to a first fragment starting from an intra-coded frame;
- and
- a control unit configured to control the transmission unit to transmit the first fragment at the resumption of transmission.
A transmission method performed by a transmission apparatus, the method comprising:
- a division step of dividing a video data into a fragment of one or more frames starting from an intra-coded frame and a fragment of one or more inter-coded frames;
- a transmitting step of transmitting the fragment of one or more frames starting from an intra-coded frame and the fragment of one or more inter-coded frames;
- a storing step of storing waiting-for-transmission fragments that are not able to be transmitted in the transmitting step;
- an eliminating step of eliminating from the waiting-for-transmission fragments a fragment of one or more inter-coded frames to be transmitted prior to a first fragment starting from an intra-coded frame;
- and
- a control step of controlling the transmitting step to transmit the first fragment at the resumption of transmission.
A non-transitory storage medium having a computer-readable program recorded thereon, the program comprising:
- a division step of dividing a video data into a fragment of one or more frames starting from an intra-coded frame and a fragment of one or more inter-coded frames;
- a transmitting step of transmitting the fragment of one or more frames starting from an intra-coded frame and the fragment of one or more inter-coded frames;
- a storing step of storing waiting-for-transmission fragments that are not able to be transmitted in the transmitting step;
- an eliminating step of eliminating from the waiting-for-transmission fragments a fragment of one or more of inter-coded frames to be transmitted prior to a first fragment starting from an intra-coded frame;
- and
- a control step of controlling the transmitting step to transmit the first fragment at the resumption of transmission.
