About the Weblog (On-Line Journal)
In English the word “weblog” means “web-journal”. On-line journal is an internet service in the form of a web page containing a record of the events in a person’s life, a kind of a diary. At bottom of fact it is a renewed page with news on various subjects, each posting can be commented by readers. More often only one person keeps a diary, that is why a weblog is an author’s work. The purpose of such journals is to write about one’s life, to express one’s opinion about worldwide events for all to see. The result is information space with a great number of mutual relations according to the interests of groups of writers.

Nowadays there are a lot of weblog resources in the Internet – for example http://www.livejournal.com, which enjoy wide popularity. And the above mentioned http://www.livejournal.com has at the moment about 7 million of users and their amount is constantly growing.

The popularity of on-line journals can be explained by the following facts:
Firstly, the Internet is available and wide-spread, as a result millions of people can hear you, estimate your powers.
Secondly, people from different parts of the world can chat on the pages of the journal.
The third reason is the simplicity of keeping a diary – any user can create his journal, having spent the minimal amount of time on the acquaintance with the rules of publication and software product.

2. About the Video Weblog (On-Line Video Journal)
On-line video journal is an internet service giving the users the opportunity to publish video materials, watch video in the on-line broadcasting mode, chat and comment clips. It is a logical development of the technology of textual diaries and it differs from a usual publication of clips in the Web in flexible controlling of media stream in real time while watching the clip (there is no need to download a full clip to view it).

3. Advantages of “Stream” Access to Information
The services that existing on-line weblog software kits provide nowadays allow the user to publish materials of any kind – a text, a picture, music, a video. At the same time there is only one single type of access to the content irrespective of its type. To get the information, the user has to download it on his computer in full volume. This type of viewing publications does not cause criticism in case of work with the content with the small volume of data transferred via the net – texts, pictures, short music clips. “Stream” access is the transmission of content in parts. This kind of access is possible if the content can be cut in pieces and each piece has a complete by implication information that can be received by the user separately. Media content – video and audio materials – has such features.

Stream access to information is more effective as the user can get it while transferring the data to the local computer. In other words, the user watches the video and listens to the music immediately during the data transfer from the server. As a rule, media content is rather “heavy” – it occupies a lot of megabytes. The user who wants to see the video has to download it on the local computer irrespectively what interests him in the clip. Working with the stream server, the user can flexibly control the viewing – to watch the things that interest personally him, sparing traffic.

4. Active Video Blog Software Kit
Active Video Blog software kit – a software complex of Active Video Company - is a turnkey solution to create video blog service. The complex includes server and client software. Server software is established by the provider of the AVB service and it interacts with client software which AVB users install on their computers. Software of Active Video Company is created according to international standards of softbuilding and interacts with each other by checked schemes that approved themselves in long world practice.

5. What does the AVB User Get?
The AVB user is a person who keeps his/her on-line journal and wants to widen the repertoire of notes with the help of video insertions. The life cycle of a video clip can be described in full measure by the following steps:
- shot material in digital format;
- clip montage;
- loading to the AVB server;
- publication of a clip link in a user’s journal (the link can have the form of clip frames);
- watching by the viewer.

AVB client software provides a complex functional that enables you to simplify the process of montage, publication of the video material on the user’s page and viewing stream video. Its basis is the idea of maximum simplicity and usability.

Video material is prepared for publishing with the help of the AVEditor utility that gives the opportunity to cut the video sequence, create audio background, download the clip to the AVB server and publish clip links, i.e. to make the whole process of author’s work automatic.

You can watch the clip with the help of the media player of Active Video Company – the AVPlayer. To start playing the clip, it is enough to click on the clip link on the author’s page. The AVPlayer will be launched and on-line broadcasting will begin. The viewer can halt the broadcasting (pause) or stop the film, rewind or fast forward the clip, change the audio track or mute the sound – at the same time he will get only those parts of media content from the server that he immediately received. In other words, if the clip was paused, the data flow from the server will be stopped; if the sound was muted, there will be no sound flow. Such an approach cuts expenditures on traffic. The AVPlaer is not an obligatory component for watching the transmission. The viewer can use Aplle – Quick time media players or Real players. But these software products are inferior to the AVPlayer in some points.

6. The Advantages of the AVPlayer over the Quick Time and Real Player
Active Video Company has a patent interactive video technology that enables the viewer to participate in the clip. It looks in the following way for the user: a video sequence has “active” objects – highlighted elements of the clip - clicking on them with the mouse the action programmed by the author will be fulfilled. Any object of the video can be active – a house, a man, a car, a mobile. The media editor AVEditor gives the opportunity to perform non-linear edit of the video – insert active objects into the clip, whose activation will change the plotline or cause other actions which give the chance to express your author’s idea.

While cutting the film, the author can choose several objects of the video sequence, make them “active” and decide what action will be performed after their activation:
- switch to another episode of the video (for example: the author shot a clip about a party, during the montage he extracted a new guest and made him an active object and set an action – switch to the scene where the man introduces himself and tells something about himself);
- opening a web page (for example: there is a DJ in the clip about the party, making active him the user opens the site with his compositions in the Internet).

Created in that way clip has a non-linear plot in reality, but in fact it is an ordinary video clip that can be played on any media player, though some functions connected with active objects will be lost.

The AVPlayer provides the user with the interface of interaction with active objects, so we recommend it when watching AVB video blogs.

7. What does the Provider of the AVB Service Get?
First of all the provider gets a ready system that enables him to expand the spectrum of services.

The AVServer is the main component of AVB server software. The main purpose of the AVServer is to provide the user with a stream access to clips located on it. The AVServer can give service to a lot of clients simultaneously with the same quality of transmission. Exceeding the limit of the server hardware possibilities is not a problem for further functioning of the system. Scaling methods – building a cluster complex of servers perceived as a whole - has been created for it. The AVServer provides administrative interface that lets you track the activity of users (moderating), and also to make traffic reports. It is possible to adjust the process of publication of new material that demands AVB administrator’s authorization of the clip content. The interface was created on the basis of the web technology – in fact it is a web page, having opened which by means of the web-browser, the administrator can manage the server.

8. AVB Integration of Server Software
The AVB provides the opportunity to expand the functional of the on-line journal – to make it a video diary; it does not demand intervention into the work of the resource or change something in it. The page of the user’s journal has a link to the clip located on the AVB server, and the physical position of the hardware platform on which the AVB server stands is not so important.

In the theme of integration one question still remains undetermined, it concerns the connection of the AVEditor with a text weblog – realization of the functional of clip links publication into the user’s diary. The point is that there are a lot of weblog engine realizations at the moment. Most of them provide API – a software interface for publishing messages on-line. The AVEditor has a functional of work with various kinds of API on the basis of plug-ins. At present we interact with Live Journal. The database of API maintained will be widened in the course of AVB development.

9. For Whom is AVB?
Weblog keepers can be of two types:
- stand-alone weblogs – separate weblog resources. This is a web service with one blog. As a rule, they are free information agencies or communities of other kind. For example: http://www.business-opportunities.biz/
- weblog portals are large resources which provide the service of creating an own weblog for Internet users. For example: http://www.livejournal.com

We offer two types of collaboration:
1. scanning server software on the side of the web-resource provider. In this case the purchase of AVB server software is registered by the owner of the web-resource.
2. using the server powers of Active Video Company. Here Active Video Company is a provider – it leases its resources. This type is more interesting for stand-alone weblog holders.
