Abstract
Description
한편, 전체 비디오의 길이가 50w이므로 마지막 분할은 21이 아닌 18로 분할이 된다. 그리고 18 크기의 데이터가 21w 시간동안 전송이 되면 되므로 7번째 채널은 의 채널크기가 필요하므로 B=6.86b가 된다.
Claims (5)
- 동영상을 포함하는 비디오 데이터를 네트워크에서 다수의 단말기로 전송하는 NVOD 서비스 방법에 있어서,비디오의 재생대역폭에 대한 단말기의 상대적인 네트워크 대역폭(m)을 확인하는 대역폭 확인단계;비디오 데이터를 분할함에 있어서, 분할크기를 상기 m에 따라 분할서열별로 다르게 분할하는 비디오 데이터 분할단계; 및상기 비디오 데이터 분할단계에서 분할된 데이터를 다수의 채널을 통해 상기 단말기에 전송하는 데이터 전송단계;를 포함하는 것을 특징으로 하는 NVOD 서비스 방법.
- 제 1 항에 있어서, 상기 데이터 전송단계는분할된 데이터가 전송되는 각 채널에서, 상기 데이터의 반복전송주기를 그 데이터의 재생시간과 일치시켜 전송하는 것을 특징으로 하는 NVOD 서비스 방법.
- 제 1 항에서 있어서, 상기 데이터 전송단계는비디오 데이터를 전송하는 서버의 전송 대역폭을 줄일 수 있도록, 마지막 분할서열의 실제 데이터 크기에 해당 채널의 대역폭을 일치시키면서 그 반복전송주기는 설정된 상기 채널의 반복전송주기로 유지하는 것을 특징으로 하는 NVOD 서비스 방법.
