Abstract
A streaming apparatus and method that streams AV data to other devices and converts the recording time stamp into a streaming time stamp format, thereby simplifying the streaming process.
Claims20
An apparatus for streaming AV data to at least one other device, said AV data having packets, at least some of said packets having a recording time stamp of m bits representing temporal information of when the packet is recorded on a storage medium, the apparatus comprising:
- a time stamp converter unit converting the recording time stamp of m bits into a streaming time stamp of n bits required for streaming the AV data to said other device, wherein m<n;
- and
- a transmission unit transmitting packets including the streaming time stamp to said other device based on a streaming protocol.
A method of streaming AV data to another device, said AV data having packets, at least some of said packets having a recording time stamp of m bits representing temporal information of when the packet is recorded on a storage medium, the method comprising:
- converting the recording time stamp of m bits into a streaming time stamp of n bits required for streaming the AV data to said other device (here, m<n);
- and
- transmitting packets including the streaming time stamp to said other device based on a streaming protocol.
A method of converting a recording time stamp of m bits of AV data containing one or more packets into a streaming time stamp of n bits wherein m<n, comprising:
- extracting the recording time stamp of an i-th packet;
- filling most significant (n-n) bits of the streaming time stamp of a first packet with zeros and filling remaining lower m bits with the recording time stamp of the first packet;
- comparing the recording time stamp Xi of the i-th packet with the recording time stamp X(i-1) of the (i-1)th packet;
- and
- filling most significant (n-n) bits of the streaming time stamp Yi of an i-th packet with a bit value obtained by incrementing the most significant (n-m) bits of the streaming time stamp Y(i-1) of an (i-1)th packet and filling the lower m bits of the streaming time stamp Yi of the i-th packet with the recording time stamp Xi when Xi<X(i-1).
