Detailed description of the invention
The embodiment of the present invention one provides the update method of the image of a kind of channel, and the method is performed by the webserver, and the method specifically includes:
The inquiry request that step 101, receiving set up box or video processing hardware send, described inquiry request is for asking whether the image needing to update described channel, and wherein said inquiry request can be periodically send。
Wherein, this step is optional step。The image of the embodiment of the present invention and subsequent embodiment mid band is: described channel is current just at the thumbnail of broadcast items；Or, described channel current just at the original image of broadcast items, subsequent embodiment will illustrate for thumbnail。
Step 102, timestamp corresponding to the image of the channel preserved, it is determined whether need to update the image of described channel, when determining that result is yes, perform step 103；When determining that result is no, perform step 104；
On the webserver, before this step, the image for certain channel (such as thumbnail) that webserver meeting receiving set up box or video processing hardware report, and for each channel can preserve this channel broadcast program most recently received N number of image (N can be any number, such as, N=1 or N=2) in image and timestamp corresponding to this image, wherein, most recently received N number of image (such as thumbnail) at least includes the image of last reception, for instance up-to-date thumbnail；This most recently received N number of image (such as thumbnail) can also include: this last front image once received, the thumbnail that such as second from the bottom time receives。This step specifically according to most recently received N number of image (N can be any number, for instance, N=1 or N=2) in the timestamp corresponding to image (such as thumbnail), determine the need for updating the image of described channel。In practical operation, it is possible to the timestamp corresponding to last preserved thumbnail determines the need for updating the thumbnail of described channel；Can also determine the need for updating the thumbnail of described channel by timestamp corresponding to the thumbnail that second from the bottom time preserves。
Concrete, this step can realize in the following way: calculates the time difference of timestamp and current time, if this time difference is more than this threshold value, it is determined that need to update the image (such as thumbnail) of described channel；If this time difference is less than or equal to this threshold value, it is determined that the image of described channel need not be updated。
Step 103, to Set Top Box or video processing hardware send need update instruction, then perform step 105。
Step 104, send the instruction that need not update to Set Top Box or video processing hardware。
Optionally, if receiving the inquiry request that Set Top Box or video processing hardware send, then the instruction in this step 104 and step 103 is the response for described inquiry request。Optionally, in another embodiment, Set Top Box or video processing hardware need not send inquiry request, and the instruction in this step 104 and step 103 is that the webserver actively sends。
Step 105, receiving the image update message that described Set Top Box or described video processing hardware send, described image update message includes: for generating the data of the image of the described channel of renewal。
Wherein, the image of described channel is the thumbnail of the program of channel, in one embodiment, is used for the data generating the image of the described channel of renewal just for the data of described thumbnail, follow-up this thumbnail of direct preservation of the webserver；Optionally, in another embodiment, more new information carries raw image data, it is raw image data for generating the data of the image of the described channel of renewal, follow-up can being produced corresponding thumbnail preserving by the webserver according to raw image data, now the data of thumbnail can be a part for raw image data。
Step 106, according to described image update message, preserve the image of the described channel updated, and preserve the timestamp corresponding to image of the channel of described renewal。
Wherein, described timestamp can be the reception time of the image (such as thumbnail) of channel program, can also being the generation time of the image of channel program, if the generation time of the image of channel program, then described image update message also includes the described generation time。Wherein, when the timestamp corresponding to image preserved is for the inquiry request of subsequently received Set Top Box or video processing hardware, it may be judged whether need corresponding Set Top Box or video processing hardware to update the image of this channel。
The image (such as thumbnail) of the renewal of the channel that the embodiment of the present invention is reported by receiving set up box, reduces the demand of expensive multipath concurrence high frequency demodulation hardware and decoding hardware。Further, by the timestamp corresponding to the channel image (such as the last thumbnail preserved) preserved, determine the need for updating the image of this channel, so as to send the instruction of more new images timely to Set Top Box or video processing hardware, the actual renewal interval making the image of this channel can control, to reach to be close to the purpose of real-time more new images (such as thumbnail)。The embodiment of the present invention does not need the singlepoint devices of intensive, adopts Set Top Box to improve system reliability and stability as this distributed framework of Producer。The embodiment of the present invention reduces the process demand to special video processing hardware, the multiplexing computing capability of terminal (i.e. Set Top Box) so that the cost of overall plan is low。Number of users is more big, more uniform in the distribution of different channel and different periods, and the requirement processing hardware hence for dedicated video is more low, and effect is more notable。
The webserver in the embodiment of the present invention preserves the image of the program of each television channel, such as thumbnail, so that when receiving the request of request channel list of client at any time, the name of each channel and the last image preserved of each channel is sent to corresponding client, so that client indicated channel list, namely show the name of each channel and the last image preserved of each channel。Wherein, client can be the client on portable equipment, such as mobile phone browser。
The embodiment of the present invention two provides the update method of the image of a kind of channel, and the method can be performed by Set Top Box, and the method includes:
Step 201, Set Top Box play the program of channel。
Step 202, Set Top Box send inquiry request to the webserver, and described inquiry request is for asking whether the image needing to update described channel program。
Wherein, in this step, inquiry request can be that Set Top Box periodically sends, and wherein, this step is optional step。
Step 203, Set Top Box receive the instruction needing to update that the webserver sends。
If Set Top Box have sent inquiry request to the webserver, then this needs the instruction reporting the image of described channel to be the response for this inquiry request。
Step 204, Set Top Box, according to the described instruction needing and updating, obtain the image that the current time of this channel broadcast program is play。
Step 205, Set Top Box send image update message to the webserver, and described image update message includes the data of acquired image, and wherein, acquired image can be the thumbnail of the original image of the original image of channel program or channel program。
In the embodiment of the present invention, Set Top Box is while playing channel program, Producer as the image (such as thumbnail) of channel program, report the image (such as thumbnail) of the program of channel to the webserver, decrease the high frequency demodulation hardware of costliness and the demand of decoding hardware。
The embodiment of the present invention three provides the update method of the image of a kind of channel, and in this embodiment, Set Top Box and video processing hardware all can send, to the webserver, the thumbnail updated, and the method specifically includes:
Step 301, Set Top Box A send inquiry request to the webserver, described inquiry request is for asking whether the thumbnail needing to update the program of described channel, wherein said inquiry request can be that Set Top Box A periodically sends, and is such as issued by one query request every 40 seconds Set Top Box A。
Step 302, the webserver obtain the timestamp corresponding to thumbnail of the program of the last described channel preserved, according to this timestamp, it is determined whether need Set Top Box A to update thumbnail, if it is desired, then perform step 303；If need not, perform step 305。
Owing to the inquiry request of Set Top Box is periodically to send, and the Set Top Box playing this channel generally has hundreds and thousands of, so the webserver can constantly receive the thumbnail of the renewal that Set Top Box reports。In this embodiment, when the webserver receives the thumbnail of renewal, last thumbnail can be replaced with the thumbnail of up-to-date reception and preserve the thumbnail of up-to-date reception and the timestamp of this up-to-date thumbnail。In this step, the webserver obtains the last timestamp corresponding to thumbnail preserved。
Wherein, this step determines the need for Set Top Box A renewal thumbnail and specifically realizes in the following way: the time difference of calculating timestamp and current time, if this time difference is more than this threshold value, it is determined that need to update the thumbnail of this channel；If this time difference is less than or equal to this threshold value, it is determined that the thumbnail of this channel need not be updated。Wherein, threshold value can be dynamically update, and will be described in detail later and how dynamically to update threshold value。
Step 303, the webserver send the instruction needing to update thumbnail to Set Top Box A。
The instruction that step 304, Set Top Box A update according to these needs, obtains the thumbnail of current time institute playing image, sends image update message to the webserver, and this image update message includes this thumbnail。The webserver deletes previously saved thumbnail, and preserves the thumbnail of Set Top Box A transmission and the timestamp that this thumbnail is corresponding。
Wherein, in this step, the webserver uses the thumbnail of up-to-date reception to replace the thumbnail of last time preservation so that what preserve is up-to-date thumbnail always。This timestamp can be the reception time of image update message, it can also be the generation time of thumbnail in step 304, if the generation time of the thumbnail in step 304, then this image update message in step 304 also includes the generation time of this thumbnail。
Step 305, the webserver send the instruction that need not update thumbnail to Set Top Box A。
Step 306, video processing hardware send the inquiry request for this channel to the webserver, and described inquiry request is for asking whether the thumbnail needing to update the program of described channel。
Wherein, video processing hardware can send inquiry request for each channel in a predetermined sequence, namely each channel carrying out one by one is inquired about。
Step 307, the webserver obtain the timestamp corresponding to thumbnail of the program of the last described channel preserved, the timestamp namely preserved in step 304。According to this timestamp, it is determined whether need video processing hardware to update the thumbnail of this channel, if it is desired, then perform step 308；If need not, perform step 310。
In this step, according to this timestamp, it is determined whether the specific implementation needing the thumbnail that video processing hardware updates this channel is similar to step 302, does not repeat them here。
Step 308, the webserver send the instruction needing to update thumbnail to video processing hardware。
Step 309, video processing hardware decode the program stream of this channel, obtain the thumbnail of program according to this program stream, send image update message to the webserver, and this image update message includes thumbnail。The webserver deletes previously saved thumbnail, and preserves the thumbnail of video processing hardware transmission and the timestamp that this thumbnail is corresponding。
Step 310, the webserver send the instruction that need not update thumbnail to video processing hardware。
In this embodiment, at any time, when the client in network receives the instruction of user's display channel list, the request of request channel list is sent to the webserver, network server to client end sends the name of each channel and the last image preserved of each channel, so that client indicated channel list, namely show the name of each channel and the last image preserved of each channel。Wherein, client can be the client on portable equipment, and such as mobile phone browser, such client can receive and show up-to-date thumbnail。
In the embodiment of the present invention, each channel carrying out one by one is inquired about by video processing hardware。Channel for some hot topics, the webserver can constantly receive Set Top Box for the inquiry request of this channel the thumbnail receiving the renewal that Set Top Box reports accordingly, accordingly even when receive the inquiry request of special video processing hardware, this special video processing hardware can also do not needed and update thumbnail for it, therefore, requirement for special video processing hardware will reduce, it is more big that number of users (is equivalent to send the quantity of the Set Top Box of inquiry request), and effect is more notable。And for the channel of some non-hot topics, play the quantity of the Set Top Box of the channel of non-hot topic and few, the Producer of such thumbnail is just few, adopts video processing hardware to participate in providing the thumbnail of channel, it is possible to ensure upgrading in time of thumbnail for non-VHI。Further, the webserver can according to the timestamp of the thumbnail preserved recently and threshold decision the need of updating thumbnail, make no matter to be VHI or non-VHI, all try one's best and meet the requirement of predetermined thumbnail renewal interval (i.e. threshold value), wherein the thumbnail renewal interval of VHI and non-VHI is possible identical is likely to difference, does not affect the realization of the present invention。
It should be noted that in this embodiment of the invention, video processing hardware can send inquiry request for each channel in a predetermined sequence, namely each channel carrying out one by one is inquired about。So no matter being VHI or non-VHI, the webserver can receive inquiry request, and performs step 306-310 accordingly。In another embodiment of the present invention, video processing hardware can send inquiry request only for non-VHI, and performs step 306-310 accordingly。In another embodiment, video processing hardware need not actively send inquiry request, but the instruction sending the thumbnail updating certain channel to video processing hardware that the webserver is actively。Wherein, VHI and non-VHI can obtain according to statistical result, such as add up the quantity of the Set Top Box sending inquiry request in certain time period, if this quantity is more than or equal to predetermined numerical value, then represent that the user watching this channel program in this time period is relatively more, so this channel is VHI；If this quantity is less than predetermined numerical value, then it represents that the user watching this channel program in this time period is fewer, so this channel is non-VHI。Wherein, channel for all normal play, the number of users of rating always can present the fluctuation of certain rule according to the programme content of different time periods, broadcasting, according to Pareto Law and long-tail law, 20% the most popular channel can concentrate the viewer of 80%, and remaining 20% viewer can be evenly distributed in remaining 80% channel。
Wherein, the threshold value mentioned in this embodiment can be dynamically update, and the process that dynamically update threshold value is described below:
First kind of way: the webserver recording scheduled time period interior timestamp corresponding to the inquiry request of each channel, according to the timestamp corresponding to each inquiry request of corresponding channel, it is determined that the average lookup time of each channel；Average lookup time according to each channel, it is determined that unified average lookup time, described unified average lookup time is the renewal threshold value for this predetermined amount of time。
Concrete, the webserver is when receiving the inquiry request for certain channel, calculate the difference of the timestamp corresponding to this inquiry request and last timestamp corresponding to inquiry request, this difference and last time is asked to receive the meansigma methods of average lookup time computed during inquiry request, average lookup time as the renewal of this inquiry request, analogize in this way, finally obtain the average lookup time of this channel in this time period。Then can the average lookup time of each channel being averaged, this meansigma methods is as unified average lookup time；Or, the average lookup time of each channel is multiplied by corresponding weight, averages again after each product addition, using this meansigma methods as unified average lookup time。Wherein, oversize for average lookup time or too short channel, it is possible to it is relatively low that corresponding weight ratio is set, it is to avoid these special channels affect the numerical value of this unified average lookup time。
The second way: recording needle is to the timestamp corresponding to the inquiry request of channel, according to the timestamp corresponding to each inquiry request of this channel, it is determined that the average lookup time of this channel；This second way and first kind of way are distinctive in that, each channel has the average lookup time of oneself, it is not necessary to unified average lookup time。
