Abstract

A method for transmitting video data to the users via a network in a transcoder of an image processing system including a storage media having a predetermined amount of storage area is disclosed. The method includes the steps of storing in the storage media, the video data provided based on the corresponding services, monitoring a traffic condition of the network to determine if transcoding is necessary; transmitting the stored video data to the corresponding users, respectively, via the network, when the transcoding is not necessary; and transcoding the stored video data to transmit the video data to the corresponding users, respectively, when the transcoding is necessary. The video data provided is based on the corresponding services includes image information having the highest quality of service from a content provider.

Dependent claims

A method for transmitting video data through a network by a transcoder of an image processing system, the transcoder including a storage media having a predetermined amount of storage area, the video data being provided according to a plurality of types of services, the method comprising the steps of:

transmitting the video data provided based on at least one of the plurality of types of services via the network, and, at the same time, temporarily storing in the storage media, a copy of a predetermined amount of the already-transmitted video data in a non-transcoded format;
monitoring a traffic condition of the network to determine if transcoding is necessary;
continuously transmitting the video data via the network, when the transcoding is not necessary;
transcoding the stored video data to transmit the video data, when the transcoding is necessary;
and
inserting a transcoding point information having PTS(Presentation Time Stamp) of the transcoding, to the video data, during packetizing the video data, wherein the transcoding point information has the PTS of non-transcoded original video data.

A method for receiving video data provided based on corresponding users, respectively, via a network, in an image processing system, the method comprising the steps of:

receiving the video data provided based on the corresponding users, respectively;
determining if transcoding point information has been inserted into the video data;
providing the received video data for display when the transcoding point information is not inserted into the video data;
identifying PTS (Presentation Time Stamp) when the video data have been transcoded, based on the transcoding point information included in the transcoded video data;
and
interrupting the providing of the received video data at the time of the PTS of the transcoding, and providing the transcoded video data for display;
wherein the received video data includes video data which are not transcoded and has the highest quality of service from a content provider, and the transcoded video data includes video data having relatively lower quality of service than that of the received video data, wherein the transcoded video data comprises a copy of non-transcoded original video data that was retrieved from a temporary storage of already-transmitted video data and transcoded, and wherein the transcoding point information has the PTS of non-transcoded original video data which have been already-transmitted to the image processing system.
