Abstract
Abstract In an NVOD system, a data storage unit is provided in a receiving apparatus, whereby a video program can be provided with an instantaneous response equivalent to the VOD system. Namely, the data of the first part of the video data is stored in the data storage unit in advance. When there is a request for reproduction, that stored data is immediately reproduced. The data after the first data is sent from a transmitting apparatus in the same way as an NVOD system heretofore. Buffering is performed in the receiving apparatus, and the resultant data is reproduced continuous with the data of the first part.

Claim 3
Dependent Claim
55 words
A data delivery system as set forth in claim 1, wherein said first storage means has a mounting means for mounting a storage medium on which said predetermined time's-worth of data of the start of each of a plurality of video programs to be delivered, provided in advance, is stored so as to enable reproduction.
Claim 4
Dependent Claim
72 words
A data delivery system as set forth in claim 1, wherein said data delivery system comprises a second data outputting means for outputting said predetermined time's worth of data of the start of the video program to be delivered, and said first storage means stores said predetermined time's worth of data of the start of the video program to be delivered transmitted from said second data outputting means via a communication path.
Claim 5
Dependent Claim
32 words
A data delivery system as set forth in claim 1, wherein said first storage means and said second storage means are the same storage device which can simultaneously store and reproduce data.
Claim 6
Dependent Claim
72 words
A data delivery system as set forth in claim 1, wherein said channel selecting means is provided in said transmitting apparatus and carries out the selection of the channel at which said data will be output earliest based on a signal transmitted from said receiving apparatus, and said transmitting apparatus further comprises a transmitting means for transmitting the data of the channel selected by said channel selecting means to said receiving apparatus.
Claim 7
Dependent Claim
80 words
A data delivery system as set forth in claim 1, wherein said transmitting apparatus further comprises a data delivering means for delivering the data of plurality of channels output from said first data outputting means to said receiving apparatus in a lump, and said channel selecting means is provided in said receiving apparatus and carries out the selection of the channel at which said data among said data of the plurality of channels delivered in a lump is output earliest.
