Method for real time protocol media recording
View Patent ↗In the face of data loss on connections between a content source and a content consumer, additional connections therebetween are opened. These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer. The proxy may then seam together data streams received from the content source across the additional connections in a recording on a computer-readable medium. The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source. This derivation may be made on the basis of identifying characteristics (e.g., packet contents) of packets from each of the data streams received from the content source.
1. A method, comprising seaming together a recording of streaming content downloaded over one or more occasions from a content source in response to an indication that data loss has occurred during playbacks from the content source, wherein (i) the downloads occur over multiple connections between the content source and a proxy disposed between the content source and one or more content consumers, (ii) the proxy seams together data streams received from the content source across the multiple connections before storing a resultant seamed stream to a computer readable medium, and (iii) the proxy constructs the seamed stream by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source.
2. The method of claim 1 wherein the information gaps are filled in with reference to timestamps and/or packets sequence numbers of packets of the data streams.
3. The method of claim 2 wherein the timestamps and/or packet sequences numbers are normalized before the information gaps are filled in.
