SUPPORTING TRANSPORT DIVERSITY AND TIME-SHIFTED BUFFERS FOR MEDIA STREAMING OVER A NETWORK |
| 摘要 |
A device for processing media data includes one or more processors configured to receive a session description protocol (SDP) message including an attribute that defines a time-shifted buffer (TSB) depth, determine an amount of memory for the TSB based on a value of the attribute, allocate the determined amount of memory to the TSB, and store at least a portion of media data associated with the SDP message in the TSB. The value for the attribute may signal the depth of the TSB in terms of playback time in seconds. The attribute may leverage the extensibility of SDP messages through, for instance, “a=” lines. For instance, the TSB depth attribute may correspond to an “a=tsb-length:” attribute. |

1. A method of processing media data, the method comprising:
receiving a session description protocol (SDP) message including an attribute that defines a time-shifted buffer (TSB) depth; determining an amount of memory for the TSB based on a value of the attribute; allocating the determined amount of memory to the TSB; and storing at least a portion of media data associated with the SDP message in the TSB. |
