Description

Improve the method and the device of network television user experience
Technical field
The present invention relates to network communication field, relate in particular to a kind of method and device that improves network television user experience.
Background technology
IPTV IPTV (Internet Protocol Television) is a kind of Network Based and technology and business of expanding, along with understanding and the application cumulative year after year of people to network, more and more widely and mainly there are following two problems in the application of IPTV in IPTV:
1) channel switches the video latency issue that causes
Video compression technology commonly used in the IPTV network comprises MPEG2, H264 etc., the basic technique principle of these video compression technologies is similar, compression can be divided into compression and interframe compression in the frame, compression is exactly directly to compress a frame image in the frame, but this kind compress mode can't be transmitted on transfer bandwidth on the common broadband networks, so must use the interframe compression, the interframe compression has only some to introduce all information of basic frame recording one width of cloth picture, other frame then only writes down relatively and the variation of basic frame, can improve compression ratio greatly like this, thereby can on common broadband networks, transmit.Be that the example explanation adopts the video of interframe compression how to transmit on broadband networks below with the mpeg format.
The MPEG video compression coding comprises three kinds of elements: basic frame is that I frame (Intra-coded frame), forward predicted frame are that P frame (Predictive frame) and bi-directional predicted frames are B frame (Bi-predictive), wherein the I frame is basic frame, write down all information of a width of cloth picture, the P frame recording is with respect to the variation of I frame or previous P frame, between B frame recording I frame and the P frame or the difference information between the adjacent P frame, and one group of continuous IPB picture is called a picture group GOP (GROUP OF PICTURE).User terminal must obtain the I frame when decoding could begin decoding, if when channel switches, missed an I frame, then has only the GOP time (normal length is that 0.5s arrives several seconds) of wait, by the time receive next I frame and just can begin decoding, video when having caused switching channels is delayed time, and has influenced the user experience of Web TV.
2) video distortion that packet loss/the mistake bag causes
Because IPTV transmits by common broadband network, and the packet loss of broadband network has only 10e-4 usually, video traffic then needs packet loss below 10e-6 because the requirement that do not reach video traffic of its packet loss, caused video distortion effect the user experience of Web TV.
For addressing the above problem (1) and problem (2), prior art provides a kind of method that improves network television user experience, and this method comprises the steps: as shown in Figure 1
Step 11, on core net, be provided for the caching server of storage of channel content;
Caching server in this step can be one or more, and the content of storage of channel also can or be stored all frames for I frame, I frame+P frame.
Step 12, when the user terminal channel switches or packet loss/mistake occur and wrap, set-top box STB (Set top Box) is as required to the caching server request message;
Step 13, receive the channel content of the corresponding described request message that caching server sends at STB after, this channel content of decoding is recovered video playback.
In realizing process of the present invention, the inventor finds method described in the prior art, and there are the following problems:
1) cost is higher
Owing to need in network, dispose caching server, increase operation and maintenance cost.
2) the transmission data of core net or backbone network are more
In order to allow single caching server manage more user terminal, the position of its deployment is generally higher, as be deployed on the core net or backbone network of metropolitan area network, like this when user terminal sends the channel content of storage, must increase core net or backbone network data quantity transmitted, take the bandwidth of core net or backbone network in a large number.
Summary of the invention
In view of above-mentioned existing in prior technology problem, embodiment of the present invention provides a kind of method and device that improves network television user experience, and described method and apparatus can reduce operation and maintenance cost, reduces the volume of transmitted data of core net or backbone network.
The specific embodiment of the present invention provides a kind of method that improves network television user experience, and described method comprises:
The data of at least one picture group video of energy buffer memory are set on user terminal;
Switch or judge under the situation of packet loss/mistake bag at channel,, will watch the user terminal formation set of terminal of same channel in the one's respective area according to the information of watching the user terminal of same channel in the one's respective area that receives;
User terminal to described set of terminal sends a request message;
Receive the information of the corresponding described request message that the user terminal of described set of terminal sends, the information of described corresponding requests message is decoded and play.
The specific embodiment of the present invention also provides a kind of device that improves network television user experience, and described device comprises:
Data buffer storage unit: the data that are used at least one picture group video of buffer memory;
Judging unit: be used to judge whether switch or packet loss/mistake bag into channel;
Receiving element: be used under judgment unit judges goes out for the situation that channel switches or packet loss/mistake is wrapped, receiving the information of watching the user terminal of same channel in the one's respective area of user terminal information dispensing device transmission;
The set of terminal unit: the user terminal that is used for watching same channel in the one's respective area constitutes set of terminal;
Transmitting element: be used for sending a request message to the user terminal of described set of terminal;
Receiver, video unit: the information that is used to receive the corresponding described request message that the user terminal of described set of terminal sends;
Decoding unit: the information that is used for corresponding described request message that described receiving element is received is decoded and is play.
The specific embodiment of the invention also provides a kind of user terminal information dispensing device, and described device comprises:
Acquiring unit: be used to obtain the user terminal information of watching same channel in the one's respective area;
Transmitting element: be used to send the user terminal information of watching same channel in the one's respective area.
By the above-mentioned technical scheme that provides as can be seen, the technical scheme of the embodiment of the invention receives required information by the user terminal to set of terminal and quickens the channel switching or recover broadcast, thereby reduced the deployment of caching server, reduced operation and maintenance cost; Again since the transfer of data between the user terminal of set of terminal not in the transmission of core net or backbone network, so also reduced volume of transmitted data on core net or the backbone network.
