Abstract:
1. An audio-visual content output apparatus having a communication device to communicate with a delivery apparatus to deliver continuously a plurality of types of audio-visual content in an arbitrary order, and to deliver content description corresponding to the audio-visual content so that the same audio-visual content is outputted at the same time in all of delivery destinations, said audio-visual content output apparatus comprising: an audio-visual content acquiring device to acquire in real time the audio-visual content delivered from the delivery apparatus via the communication device; an audio-visual content outputting device to output in real time the audio-visual content acquired by the audio-visual content acquiring device; a content description acquiring device to acquire the content description corresponding to the audio-visual content outputted by the audio-visual content outputting device from the delivery apparatus via the communication device; an availability period acquiring device to acquire a timing description for identifying an availability period of the content description acquired by the content description acquiring device from the delivery apparatus via the communication device; a content description outputting period calculating device to calculate a content-description outputting period for outputting the content description acquired by the content description acquiring device based on the timing description acquired by the timing description acquiring device; and a content description outputting device to output the content description acquired by the content description acquiring device in the content description outputting period calculated by the content description outputting period calculating device, and to stop outputting the content description in response to an end of the content description outputting period; wherein the content description acquiring device acquires the content description to be delivered next by the delivery apparatus at acquiring timing determined arbitrarily in the content description outputting period, wherein the timing description acquiring device acquires the timing description corresponding to the content description to be delivered next, and wherein the content description outputting period calculating device calculates the content description outputting period based on the timing description corresponding to the content description to be delivered next.
