METHOD AND DEVICE FOR IDENTIFYING AND OBTAINING AMBE ENCODING AND DECODING RATE INFORMATION IN SDP |
摘要 |
The present invention provides a method and a device for identifying and obtaining AMBE encoding and decoding rate information in an SDP. The method for identifying the AMBE encoding and decoding rate information in the SDP includes: setting an SDP, which specifically includes: in an m attribute line of the SDP, using a payload type PT value to describe AMBE encoding and decoding, and in an fmtp attribute of an a attribute line of the SDP, identifying, in a format field, a PT value same as that of the m attribute line, and identifying AMBE encoding and decoding rate information in a format specific parameter field; and sending the set SDP to a peer end. The method and the device for identifying and obtaining the AMBE encoding and decoding rate information in the SDP provided by the present invention can implement automatic rate switching in a bearer plane. |

1. A method for identifying advanced multiband excitation vocoder AMBE encoding and decoding rate information in a session description protocol SDP, comprising:
setting an SDP, which specifically comprises: in an m attribute line of the SDP, using a payload type PT value to describe AMBE encoding and decoding; and in an fmtp attribute of an a attribute line of the SDP, identifying, in a format field, a PT value same as that of the m attribute line, and identifying AMBE encoding and decoding rate information in a format specific parameter field; and sending the set SDP to a peer end. |
