Description
[technical field]
The invention relates to a kind of video interactive system, more particularly, relate to a kind of digital video video recording and program request video recording system of interaction.
[background technology]
Development along with radio and television services, TV station is more and more, TV programme is more and more abundanter, people can receive tens programs to up to a hundred television channels, after Digital Television occurs, television channel quantity will continue to increase, and it is individual to reach hundreds of, and TV more and more becomes the indispensable media that obtains information, amusement and recreation in people's daily life.But common television system has some shortcomings, and promptly the user can only watch the TV programme of some channels of present moment broadcast, the TV programme of the broadcast of can not watching over, the TV programme that can not watch two or more channels simultaneously.
For addressing this problem, people have proposed certain methods, as the PVR----personal digital video recorder, can set in advance oneself not free performance recording of watching is got off to watch, and also can realize the function of live telecast, time-moving television.But not recording the program that gets off for the past then can't watch.
Also has a kind of method, promptly adopt (the Internet Protocol Television of IPTV system, IPTV), at system end with all TV programme and movie program all under the recording and storing, the user is connected to system end by set-top box from broadband network, on television set, watch program or the real-time television program that is stored in system end by set-top box and broadband network, and can realize functions such as live telecast, time-moving television.But this method has following shortcoming:
(1) system equipment complexity, very high to the reliability and stability requirement, cause system equipment cost height;
(2) very high to bandwidth/stability/error rate/multicast performance requirement of broadband networks, the transformation that need carry out broadband networks in a lot of zones just can provide the IPTV business;
Produce serious bandwidth bottleneck when (3) doing;
(4) because the user is accustomed to watching TV during the 19:00-22:00 at night, so the IPTV system can not improve the utilance of broadband network, the Congestion Level SPCC of peak hours/period aggravation broadband network that on the contrary can be at night;
(5) in order to realize the function of live telecast, time-moving television, when watching the real-time television program under the IPTV system, the user also must pass through broadband network, and can not be by local cable TV network;
(6) can not provide the service of differentiation to the user.
In sum, utilize the method that adopts in the market still can not solve people's existing deficiency when televiewing well.
Therefore, provide that a kind of system is simple, reliability and stability are higher, cost is low, improve the utilance of broadband network, can provide the digital video video recording of personalized interactive service and program request video recording system real for necessary.
[summary of the invention]
The object of the present invention is to provide that a kind of system is simple, reliability and stability are higher, cost is low, improve the utilance of broadband network, video recording of the digital video that can provide personalized service and program request video recording system.
To achieve these goals, the present invention adopts following technical scheme:
The invention discloses a kind of digital video video recording and program request video recording system, it comprises system end equipment and ustomer premises access equipment, this system end equipment comprises the system front end processing module that is linked in sequence, content storage module, the content distribution module, and connect and manage this front-end processing module, content storage module, the system management module of content distribution module, this ustomer premises access equipment comprises the user front end processing module that is linked in sequence, content storage module, the broadband interface module, and connect and control this user front end processing module, content storage module, the control module of broadband interface module, between this system end equipment and the ustomer premises access equipment by Internet connection.
