Description
Technical field
The present invention relates to field of video transmission, particularly relate to a kind of broadcasting, the method transmitting programme televised live and intelligent playback equipment, live equipment.
Background technology
Along with the fast development of the Internet, intelligence playback equipment is popularized, viewing live television programming is no longer confined to the live equipment (such as Set Top Box, television set) with broadcast television reception function, and increasing people bring into use intelligent playback equipment (such as mobile phone, PAD etc.) to go anywhere or anytime to watch live content.
At present, watch live normal method by intelligent playback equipment and have following two kinds:
(1) by programme televised live that public network utilizes live software to watch it to provide.This mode needs erection video server and forwarding server, and realize complicated, expense is huge, and programme televised live source is considerably less, does not particularly have the program of local channel.
(2) its live content provided is watched by the live equipment connected in same local area network (LAN).This mode limits intelligent playback equipment and live equipment must in same local area network (LAN).
In addition, following several technical schemes are mainly contained by public network viewing programme televised live at present:
(1) by udp protocol transmitted video content, the program can be used for P2P transmission, and transmission express delivery is fast, but its shortcoming is that the transmission of data is without any guarantee, under public network environment, packet loss is serious, and data order of arrival entanglement (data first sent not necessarily first are received), cause to play to block and time or mosaic, and multimedia system in intelligent playback equipment non-protogenous support, need to develop player separately.
(2) video content is transmitted by Real-time Transport Protocol, the program can be used for P2P transmission, realize based on UDP, by increasing the status report of sequence number and timestamp and communication two ends, solve the out of order problem of UDP to a certain extent, shortcoming is the problem that still cannot solve packet loss, and multimedia system in intelligent playback equipment non-protogenous support.
(3) video content is transmitted by HLS protocol, the program is that Apple proposes, be mainly used in providing live and program request ability to apple equipment, adopt TCP transmitting, there is no out of order and problem that is packet loss, and the primary support of the primary support of multimedia system in intelligent playback equipment particularly apple equipment, but its shortcoming is that TCP cannot be used for P2P transmission.
(4) video content is transmitted by RTSP agreement, the program adds TCP channel transferring command on the basis of Real-time Transport Protocol, but its shortcoming relies on RTP in the problem of transmission of video, the problem of packet loss cannot be solved, TCP cannot be used for P2P transmission, and multimedia system in intelligent playback equipment non-protogenous support.
Visible, if want to watch programme televised live by P2P mode on public network and the primary support of multimedia system that can allow in intelligent playback equipment, existing scheme is all not suitable for, in the urgent need to a kind of P2P technology that can utilize by the method for public network transmission programme televised live.
