Abstract
Embodiments of the present invention provide a data processing method, including: obtaining, by a receiving device, a first data packet sequence; determining, according to an identifier of a data packet in the first data packet sequence, an identifier of a data packet lost in a transmission process of the transmission system; determining an estimated value of the lost data packet according to a value of the data packet in the first data packet sequence; combining the value of the data packet in the first data packet sequence with the estimated value of the lost data packet as a second data packet sequence corresponding to the source data packet sequence; and performing digital signal processing on the second data packet sequence.
Claims16
A data processing method, comprising:
- obtaining, by a receiving device, a first data packet sequence, wherein the first data packet sequence comprises a data packet that is in a source data packet sequence sent by a source device and that reaches the receiving device by using a transmission system, and the first data packet sequence is a subset of the source data packet sequence;
- determining, by the receiving device according to an identifier of a data packet in the first data packet sequence, an identifier of a data packet lost in a transmission process of the transmission system;
- determining, by the receiving device, an estimated value of the lost data packet according to a value of the data packet in the first data packet sequence;
- combining, by the receiving device, the value of the data packet in the first data packet sequence with the estimated value of the lost data packet as a second data packet sequence corresponding to the source data packet sequence;
- and
- performing, by the receiving device, digital signal processing on the second data packet sequence.
A receiving device, comprising:
- a communications interface configured to obtain a first data packet sequence, wherein the first data packet sequence includes a data packet that is in a source data packet sequence sent by a source device and that reaches the receiving device by using a transmission system, and the first data packet sequence is a subset of the source data packet sequence;
- and
- a processor configured to:
- determine, according to an identifier of a data packet in the first data packet sequence obtained by the communications interface, an identifier of a data packet lost in a transmission process of the transmission system,
- determine an estimated value of the lost data packet according to a value of the data packet in the first data packet sequence obtained by the communications interface,
- combine the value of the data packet in the first data packet sequence obtained by the communications interface with the estimated value of the lost data packet as a second data packet sequence corresponding to the source data packet sequence, and
- perform digital signal processing on the second data packet sequence.
