Broadcasting apparatus and method for pre-transmitting data carousel and receiving apparatus for receiving data carousel

A broadcasting system including a broadcasting apparatus and a receiving apparatus, wherein

• the broadcasting apparatus comprises:
• a transmitting means for transmitting an interactive content as a data carousel over a span of a scheduled broadcasting time period;
• and
• a transmission control means for controlling the transmitting means so as to (a) start pre-transmitting the interactive content a predetermined time before the start of the scheduled broadcasting time period, and (b) repeatedly transmit a cache message that instructs a receiving apparatus to cache the interactive content into a storage unit in the receiving apparatus while the transmitting means pre-transmits the interactive content over a span of the predetermined time period, and
• the receiving apparatus comprises:
• a receiving means for receiving the interactive content transmitted as the data carousel;
• a reproducing means for reproducing the received interactive content;
• and
• a reception control means for controlling the reproducing means so as to (a) cache the interactive content into a storage unit, not reproducing the interactive content, while the interactive content is received before the start of a scheduled broadcasting time period, and (b) reproduce the interactive content during the scheduled broadcasting time period.

A broadcasting method of allowing a broadcasting apparatus to transmit a data carousel, comprising:

• a first transmitting step for pre-transmitting an interactive content as the data carousel, starting a predetermined time before the start of a scheduled broadcasting time period;
• a cache message transmitting step for repeatedly transmitting a cache message that instructs a receiving apparatus to cache the interactive content into a storage unit in the receiving apparatus while the interactive content is pre-transmitted in the first transmitting step;
• and
• a second transmitting step for broadcasting the interactive content as the data carousel during the scheduled broadcasting time period.

A computer program that allows a broadcasting apparatus to transmit a data carousel, the computer program allowing a computer in the broadcasting apparatus to execute:

• a first transmitting step for pre-transmitting an interactive content as the data carousel, starting a predetermined time before the start of a scheduled broadcasting time period;
• a cache message transmitting step for repeatedly transmitting a cache message that instructs a receiving apparatus to cache the interactive content into a storage unit in the receiving apparatus while the interactive content is pre-transmitted in the first transmitting step;
• and
• a second transmitting step for broadcasting the interactive content as the data carousel during the scheduled broadcasting time period.
