Abstract

A VOD server refers to advertisement delivery information, and inserts a stream of advertising content in a stream of video content of a main part, based on advertisement inserting position information indicating an inserting position of the advertising content to be inserted into the video content of the main part, for delivery to a client terminal. When making this delivery, at least time information, such as time management information of reproduced output or decoding, to be added to the stream of the video content of the main part and the stream of the advertising content to be delivered to the client terminal, is replaced by time information in accordance with an order of the streams to be delivered to the client terminal.

Claims

1. An advertisement inserting VOD delivery method comprising:

delivering to a client terminal a stream of a video content of a main part by inserting a stream of an advertising content into the stream of the video content of the main part, based on advertisement inserting position information indicating an inserting position of the advertising content to be inserted into the video content of the main part; and

replacing time information to be added to the stream of the video content of the main part and the stream of the advertising content to be delivered to the client terminal by continuous time information in accordance with an order of the streams to be delivered to the client terminal, said time information being one of program time reference value, time management information of reproduced output and time management information of decoding.

2. The advertisement inserting VOD delivery method as claimed in claim 1, comprising:

computing and storing in advance the continuous time information in the order of the streams to be delivered to the client terminal, based on the advertisement inserting position information and the time information added to each stream of the video content of each main part and to each stream of each advertising content, for each combination of the video content of each main part and each advertising content.

3. A VOD server comprising:

a content control part configured to deliver to a client terminal a stream of a video content of a main part by inserting a stream of an advertising content into the stream of the video content of the main part, based on advertisement inserting position information indicating an inserting position of the advertising content to be inserted into the video content of the main part; and

a time information inserting part configured to replace time information to be added to the stream of the video content of the main part and the stream of the advertising content to be delivered to the client terminal by continuous time information in accordance with an order of the streams to be delivered to the client terminal, said time information being one of program time reference value, time management information of reproduced output and time management information of decoding.

4. The VOD server as claimed in claim 3, further comprising:

means for computing and storing in advance the continuous time information in the order of the streams to be delivered to the client terminal, based on the advertisement inserting position information and the time information added to each stream of the video content of each main part and to each stream of each advertising content, for each combination of the video content of each main part and each advertising content.
