Storage of advanced video coding (AVC) parameter sets in AVC file format
View Patent ↗There is provided a method for employing Parameter Set information corresponding to an Advanced Video Coding (AVC) file. The method includes the step of embedding the Parameter Set information into a Hint Track of the AVC file.
1. A method for streaming a file containing video information, comprising the step of:
embedding parameter information for facilitating streaming of the video information by embedding the parameter information in a Session Description Protocol (SDP) payload of a hint track of the file, the file also holding the video information such that the parameter information resides separate from the video information so that the parameter information can be streamed independent of the video information.
2. The method of claim 1 , wherein the step of embedding the parameter further comprises the step of encoding the parameter information in Multipurpose Internet Mail Extensions (MIME) prior to being embedded within the SDP payload of the Hint track.
3. The method of claim 1 , further comprising the step of transmitting the parameter information in an out-of-band transmission.
4. The method of claim 3 , wherein said transmitting step further comprises the step of transmitting the parameter information using Transmission Control Protocol (TCP).
5. The method of claim 3 , wherein said transmitting step further comprises the step of transmitting the parameter information using Real Time Streaming Protocol.
6. The method of claim 1 , further comprising the step of transmitting the parameter information in a media independent transmission.
7. The method of claim 1 , wherein said transmitting step comprises the step of transmitting the parameter information prior to any media corresponding thereto.
8. The method of claim 1 , further comprising the step of extracting the parameter information from metadata corresponding to at least one media stream.
9. An apparatus for employing parameter information corresponding to a video information file, comprising:
an embedding device embedding for parameter information for facilitating streaming of the video information by embedding the parameter information in a Session Description Protocol (SDP) payload of a hint track of the file, the file also holding the video information such that the parameter information resides separate from the video information so that the parameter information can be streamed independent of the video information.
10. The apparatus of claim 9 , wherein the parameter information embedded within the SDP payload by said embedding device is encoded in Multipurpose Internet Mail Extensions (MIME).
11. The apparatus of claim 9 , further comprising a transmitter for transmitting the parameter information in an out-of-band transmission.
12. The apparatus of claim 11 , wherein said transmitter transmits the Parameter Set information using Transmission Control Protocol.
13. The apparatus of claim 11 , wherein said transmitter transmits the Parameter Set information using Real Time Streaming Protocol.
14. The apparatus of claim 9 further comprising a transmitter for transmitting the parameter information in a media independent transmission.
15. The apparatus of claim 9 , wherein said transmitter transmits the parameter information prior to any media corresponding thereto.
16. The apparatus of claim 9 , further comprising an extractor for extracting the parameter from metadata corresponding to at least one media stream.
