Specific embodiment
Below in conjunction with drawings and examples, specific embodiments of the present invention will be described in further detail.Following reality Example is applied for illustrating the present invention, but is not intended to limit the scope of the invention.
RTP data packet disorder rearrangement method according to an embodiment of the present invention is specifically described in conjunction with attached drawing first below.
As shown in Figure 1, RTP data packet disorder rearrangement method according to an embodiment of the present invention includes:
It receives RTP data packet and parses the sequence number carried in the RTP data packet.
Judge the received RTP data packet whether be intended recipient data packet, if so, by the RTP data packet Team out, if it is not, the RTP data packet is then entered buffering queue.
Judge whether the buffering queue overflows, if so, by the smallest RTP of sequence number in the RTP data packet Data packet goes out team, if it is not, then the RTP data packet is joined the team.
Judge the smallest RTP data packet of sequence number in buffering queue whether be next intended recipient data packet, If so, the RTP data packet is gone out team, and continue to judge in buffering queue whether is the smallest RTP data packet of sequence number For the data packet of next intended recipient.
In other words, RTP data packet disorder rearrangement method according to an embodiment of the present invention is after receiving RTP data packet, first The sequence number that carries in parsing RTP data packet, then judge the RTP data packet received whether be intended recipient data packet, If a determination be made that RTP data packet is directly then gone out into team, if it is judged that be not that then the preparation of RTP data packet is joined the team, Into buffering queue.Next, it is determined that whether buffering queue overflows, if buffering queue overflows, sequence in buffering queue is selected Number the smallest RTP data packet goes out team, if do not overflowed, RTP data packet is joined the team.After RTP data packet is joined the team, judgement is slow Rush minmal sequence number in queue RTP data packet whether be next intended recipient data packet, if a determination be made that, then will RTP data packet directly goes out team, and whether the RTP data packet for checking again for minmal sequence number in buffering queue is next it is expected that connecing The data packet of receipts.
Wherein, judge whether the received RTP data packet is the data packet of intended recipient for by the institute for judging to receive Whether the sequence number for stating RTP data packet is that the sequence number of data packet of intended recipient is judged.
RTP data packet disorder rearrangement method according to an embodiment of the present invention as a result, can estimate following network jitter simultaneously The depth for adaptively increasing or decreasing buffering queue in the occupancy resource for reducing program to the greatest extent, and guarantees the high-quality of transmission of video In the case that amount is with timeliness, the out-of-order rearrangement effect that is optimal.
According to one embodiment of present invention, the reception RTP data packet and the sequence carried in the RTP data packet is parsed Row number, comprising:
