Method for serving multimedia data on demand using dynamic channel and apparatus thereof

A method of serving multimedia data on demand, comprising:

• continuously transmitting the multimedia data from the beginning to the end via a first static channel at a first static channel transmission point;
• transmitting a portion of the multimedia data from the beginning via a first to dth dynamic channel at a first to dth dynamic channel transmission point, wherein d is a natural number not less than 1;
• reusing the kth dynamic channel as another dynamic channel after releasing the kth dynamic channel to be available after Tk from the kth dynamic channel transmission point, wherein the Tk is not less than an elapsed time from the first static channel transmission point to the kth dynamic channel transmission point, wherein k is greater than 1 and less than d;
• continuously transmitting the multimedia data from the beginning to the end via a second static channel at a second static channel transmission point;
• receiving a video subscription request from a subscriber apparatus;
• and
• transmitting a transmission schedule in response to the video subscription request to the subscriber apparatus, wherein the transmission schedule comprises at least one of the first and the second static channel transmission points, and the first to the dth dynamic channel transmission points,
• wherein each of the first to the dth dynamic channels among plural channels is available at each dynamic channel transmission point,
• and wherein the kth dynamic channel transmission point is located at any point between the first static channel transmission point and the second static channel transmission point and becomes closer to the second static channel transmission point as k increases.

A method of serving multimedia data on demand, comprising:

• transmitting, at a multimedia data server device, the entire multimedia data via a first and a second static channel;
• transmitting, at the multimedia data server, a portion of the multimedia data via a first to a dth dynamic channel that is located between the first and second static channels, wherein d is a natural number not less than 1;
• and
• releasing, at the multimedia data server, the first to the dth dynamic channel(s),
• wherein the first static channel, the first to the dth dynamic channel(s) and the second static channel successively start to transmit the multimedia data by an interval of T, wherein T is a real number not less than 0,
• and wherein the first to the dth dynamic channel(s) can be reused after being released.

A computer-readable medium including a program containing computer-executable instructions in a multimedia data server for performing method of serving multimedia data on demand, the method comprising:

• continuously transmitting the multimedia data from the beginning to the end via a first static channel at a first static channel transmission point;
• transmitting a portion of the multimedia data from the beginning via a first to dth dynamic channel at a first to dth dynamic channel transmission point, wherein d is a natural number not less than 1;
• reusing a kth dynamic channel as another dynamic channel after releasing the kth dynamic channel to be available after time Tk passes from the kth dynamic channel transmission point, wherein the time Tk is not less than an elapsed time from the first static channel transmission point to the kth dynamic channel transmission point, and wherein k is a natural number not less than 1 and not greater than d;
• and
• continuously transmitting the multimedia data from the beginning to the end via a second static channel at a second static channel transmission point,
• wherein each of the first to the dth dynamic channel(s) among plural channels is available at each dynamic channel transmission point,
• and wherein the kth dynamic channel transmission point is located at any point between the first static channel transmission point and the second static channel transmission point and becomes close to the second static channel transmission point as k increases.

A method of serving multimedia data on demand, comprising:

• transmitting a portion of a multimedia data stream from the beginning of the data stream to a subscriber device via at least one dynamic channel between two adjacent static channels, wherein the at least one dynamic channel is reusable after release from the communication with the subscriber device, and wherein the entire multimedia data is transmitted to the subscriber device via the static channels;
• transmitting a portion of the multimedia data via a first dynamic channel to a dth dynamic channel that is located between first and second static channels, wherein d is a natural number greater than 1;
• and
• releasing the first dynamic channel to the dth dynamic channels,
• wherein the first static channel, the first dynamic channel to the dth dynamic channels and the second static channel successively start to transmit the multimedia data by an interval of T, wherein T is a real number not less than 0.
