Abstract
The present invention relates to a method for estimating network jitter, which has the effect of more precisely estimating network jitter by using time information corresponding to a transmission time, which is transmitted from a transport layer in a transmitting end to a receiving end.
Claims23
A method for transporting media data in an apparatus for transporting coded media data, the method comprising:
- generating an MMT transport packet by using a timestamp indicating an instant at which coded media data and the MMT transport packet are transported.
An apparatus for transporting media data for transporting coded media data, the apparatus comprising:
- an MMT transport packet generation unit configured to generate an MMT transport packet by using a timestamp indicating an instant at which coded media data and the MMT transport packet are to be transported.
A method for estimating network jitter in an apparatus for receiving coded media data, the method comprising:
- calculating network jitter by using a time stamp generated in an MMT transport packet, by an MMT transport packet generation unit of a media data transporting apparatus, to indicate an instant at which media data is transported and an instant at which the media data is received by the media data receiving apparatus.
An apparatus for estimating network jitter in an apparatus for receiving coded media data, the apparatus comprising:
- a network jitter estimating unit configured to calculate network jitter by using a time stamp generated by an MMT transport packet generation unit of a media data transporting apparatus in an MMT transport packet to indicate an instant at which media data is transported and an instant at which the media data was received by the media data receiving apparatus.
An MMT transport packet structure used for transporting coded media data comprises:
- a time stamp generated by an MMT transport packet generation unit of a coded media data transporting apparatus to indicate time information of an instant at which an MMT transport packet is transported.
