Description
Technical field
The present invention relates to IPTV Electronic Program Guide technology, particularly relate to the intelligent electronic program airmanship.
Background technology
Along with the division of labor of the variation of the form of expression of the increase of the development of computer communication technology, broadband services, service, detailsization with cooperate, for Digital Television has been brought revolutionary development prospect.Compare with simulated television, big characteristics of Digital Television are exactly can transmit a large amount of programs on same frequency band.But how to make spectators are convenient in a large amount of programs promptly to be searched for program and understands programme information, just becomes important key link, and realizes that the instrument of this purpose is exactly intelligent electro-program guiding system (EPG).
Intelligent electro-program guiding system has obtained using widely in Digital Television such as U.S., Europe development country early, becomes one of basic service of Digital Television.According to statistics, in all kinds of business of Digital Television, the clicking rate of intelligent electro-program guiding system is the highest, and becomes in the Digital Television one gradually and develop industry rapidly, the manufacturing company as the intelligent electro-program guiding system exploitation of a collection of specialties such as U.S. TV Guide occurred.In fact, intelligent electro-program guiding system has become the important symbol of Digital Television, is the door that spectators enter Digital Television.
Electronic program guidance system is user and extraneous mutual bridge, the intelligent electro-program guiding system user side of the service request that the user sends in set-top box sends, and the control information of receiving center system and through the programme information of overcompression, then to these MPEG (MPEG-encoded mode) transmission stream decoding and deliver to user's television set.Finish the intelligent electro-program guiding system guide, set-top box must at first receive electronic menu and it is presented on user's the terminal.This electronic menu has shown the various programs that the same day, centring system provided, and program is organized layout (under each COS the sub-services type can be arranged) by COS, and such layout of organizing more helps the user is conducted a sightseeing tour.Electronic menu generates after be collapsed into mpeg transport stream, broadcasts (it is to transmit in order to be suitable for that electronic menu finally is compressed into mpeg transport stream) by CATV common channels such as (cable TVs) in network then.
The design of electronic menu relates to two aspects: 1. program is organized layout by COS, and the sub-services type is arranged again under each COS, has formed the tree of menu, and the least significant end of tree is only program.Want and correctly to conduct a sightseeing tour, must carry out the redirect of menu page by user's request to the user.2. the display message of Shu each must be correct, and especially the actual name of the display Name of program and program wants consistent.In addition, also have appearance characteristics such as font and color thereof.This shows that electronic menu can be divided into two parts, the setting of the generation of menu jump list and menu page and appearance characteristics.It below is traditional intelligent electro-program guiding system design.
Scheme one: select for use the file sequence of mpeg format to preserve.Represent to have the advantage of changing base map or commercial breaks at any time with the mpeg frame sequence, but also there are many weak points, for example, adopt this scheme, the data volume of menu is bigger, when transmitting on common channel, if server sends menu information with fixed rate, the time of reception of menu is long, and the switching between the menu is just slack-off.Can certainly solve this problem with the quantity that increases common channel, but just reduce the utilance of channel like this.
Scheme two: preserve electronic menu with bitmap (bmp) form.Promptly, on the base map of each menu item, embed the Word message of respective menu items, press page number, the item No. of menu and preserve menu at each page, each base map separately that superposes respectively of menu.With the method representation menu of bitmap format significantly compress bitmap to very little data volume, when server sends menu information with fixed rate, the time of reception of menu is short, the switching delay time between the menu is also shorter relatively, improved the utilance of channel when having improved performance again, this is that the mpeg frame Format Series Lines does not have.But blemish in an otherwise perfect thing is, when adopting bitmap format, and menu base map or do not have, or just can only be placed in the set-top box, can not upgrade at any time, inconvenience breaks for commercialsy.Menu page is represented to cut both ways with mpeg frame sequence and bitmap format.EPG (intelligent electro-program guiding system) is in system and user interactions foremost, and when correctly finishing the electronic programming guide, response speed also is a very important factor.For quicker response is arranged, can adopt the 3rd kind of scheme-Hanzi internal code.
Scheme three: adopt Hanzi internal code to realize.In STB (set-top box), preset the small library of Chinese characters in common use.STB according to these information and the small library that presets, generates guide's menu automatically behind the chain list file of receiving menu and menu information.Adopt this scheme to make menu, data volume is littler.For example, 1000 Chinese characters of 24 dot matrix have only 72K, and 300 Chinese characters have only 21K, and 100 Chinese characters only have only 7K.And under the situation of 100 Chinese characters, adopting the bmp form, data volume just has more than the 32K, adopts mpeg format then more.This shows, can shorten the time that receives menu greatly when coding mode generates menu in adopting, obviously also will increase substantially the menu switching response time.But then, because the small library that presets only comprises part Chinese character commonly used among the STB,, must also exist the Chinese character that is of little use that does not comprise in some small library to appear at possibility in the menu though the Chinese character amount of menu itself is little.This situation will cause Hanzi internal code to produce error code, thereby causes menu can not correctly show these Chinese characters.
