Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data receiving apparatus and a data distribution system, and more particularly to data distribution combining narrowband personal information and broadband common information.

[0002]

2. Description of the Related Art In recent years, the population of commercial Internet users has rapidly increased. Conventionally, an analog public telephone line is used to connect to a service provider by a PPP dial-up connection and access the Internet. Access using a telephone line had a maximum transmission speed of 56 kbps. If you use ISDN or PHS, 6
A connection of 4 kbps to 128 kbps (64 kbps × 2) is common.

Recently, a broadband access network has appeared, and 384
Commercial Internet access of more than kbps is possible. Among them, the Internet access service via a cable TV line has a structure in which a transmission rate of about 30 Mbps is shared by a plurality of users. XDSL attracts attention after cable internet. xDSL has a transmission rate of 2 to 3 from service provider to user depending on the system and communication distance.
Mbps or less. A currently available for commercial use
DSL has a bandwidth of about several hundred kbps. Similarly, in an access method using a satellite or an optical fiber, several Mbp
s band is shared.

[0004] The contents provided by service providers are becoming more abundant as the access network becomes broader. Contents close to moving pictures, video contents requiring a wide band, and music contents with high sound quality are increasing. For example, by providing a pseudo-banner advertisement using a slide show technique by combining a plurality of still images, the advertisement effect is improved, the revenue from the advertisement fee is increased, and the service fee to the user is reduced.

[0005] In consideration of the future situation, there is a demand for a data receiving apparatus that provides an environment in which a service provider can provide AV data with high quality and high video effects, and can obtain data intended by a user quickly and comfortably. I have.

[0006]

However, since AV data with high quality and high video effects has a large file size, it takes a long time to download, and a large transmission bandwidth is required for real-time distribution. I do. When a service provider provides such an advertisement as a video banner, it takes time for the user to intentionally display the data that the user wants to obtain. Considering the user's access environment, it is necessary to transmit contents whose data volume is one step lower even though the data distribution on the Internet is broadened.

[0007] The reason is that, even when a broadband access network is used, the execution speed is reduced when a plurality of users access simultaneously to share the same band, resulting in an access environment close to a narrow band. That is, it takes a long time to receive data, especially at the peak of access.

[0008] AV data with high quality and high video effects is transmitted every time a user accesses the same, so that the same content flows on a plurality of networks, and the backbone traffic increases.

[0009] On the other hand, broadband access networks such as cable television have appeared, but are limited to some areas, and the coverage is much wider in a narrowband network. Therefore, it is difficult to provide high quality AV data with high video effects.

[0010] It is an object of the present invention to provide a distribution system that allows a service provider to provide AV data with high quality and high video effects, and to obtain data intended by a user quickly and comfortably.

[0011]

In order to solve the above-mentioned problems, common data, especially data requiring a wide band such as a video, is simultaneously broadcast simultaneously over a wide band channel, and the data is comparatively broadcast. A small amount of user personal data provides a data receiving device that is accessed on a narrow band channel. The common data and the personal data transmitted in this way are displayed in different areas of the same display screen. It also supports the function of automatically collecting a data presentation fee for a data provider by displaying common data. Specifically, this is performed as follows.

The data receiving apparatus receives a first data group via a first communication channel, and forcibly receives a second reproduced data group via a second communication channel when accessing the first data. One data group is restored to first playback data by a first playback method, the second data group is restored to second playback data by a second playback method, and the first playback data and the second playback data are simultaneously reproduced. It is displayed on the same screen.

The data receiving device receives a first data group via a first communication channel, forcibly receives a second data group via a second communication channel when accessing the first data, and transmits the first data group. First playback data is restored to first playback data by the first playback method, and the second data group is restored to second playback data by the second playback method.
A data receiving device for restoring with reproduction data and displaying the first reproduction data and the second reproduction data simultaneously on the same screen, displaying the first reproduction data in a first area of the screen, 2. The reproduction data is displayed in a second area of the screen.

According to the above configuration, since the areas in which the first and second reproduced data are to be displayed are determined in advance, the display area can be determined each time according to the content and type of each data. Therefore, it is possible to provide data according to the characteristics of the data to be reproduced. The display area may change based on the content of the first reproduction data.

The present invention further provides the following data receiving device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram showing an embodiment of a data distribution system including a data receiving apparatus according to the present invention.
In FIG. 1, reference numeral 100 designates a primary distribution system for mainly delivering personal data.
Server, 101 is a second server for distributing common data, 102 is second transmitting means (transmitting antenna), 103 is a public line, 104 to 107 are receiving terminals, and 108 to 1
11 is a receiving means (receiving antenna) corresponding to each receiving terminal
It is.

The second server 101 is provided with the second transmitting means 10
2 to distribute common data to the receiving terminals (104 to 107). In the present embodiment, high-quality video data and high-quality audio data that require a high transmission band are used as common data, and are used for advertisements, BGM, and BGV that are commonly displayed on a receiving terminal. Second
The transmitting means 102 is an antenna for transmitting these data. The receiving devices (104 to 107) include a hard disk and other storage media for recording digital data. The data distributed by the second transmission unit 102 is reproduced and displayed in real time or stored in a storage medium. The first server 100 is a server for distributing personal data (e-mail, account data, purchase record, schedule table, etc.) of a user having a receiving terminal, a result of a search by the user, and the like. That is, the first server is for distributing user-specific data. Although FIG. 1 illustrates four receiving devices, the present invention is not limited to this. In addition, the first server 10
The first and second servers 100 are not different, and may be the same server. The transmission paths 112 and 114 may be the same. That is, instead of using the illustrated broadcasting network and public telephone network together, the same broadband public network may be used for simultaneous distribution by the IP multicast method.

FIG. 10 is a schematic diagram of a screen displaying data distributed by the data receiving apparatus according to the embodiment of the present invention on a receiving terminal. Reference numeral 1010 denotes an entire display screen, 1011 denotes common data, and 1012 denotes an area for displaying personal data. 1011 is a second display area, and 1012 is a first display area.
This is a display area. A display method other than that shown in FIG. 10 may be used. In the present embodiment, since the 1011 common data is broadcast simultaneously on a broadband broadcast network, it is possible to distribute data with high image quality and high video effect, and to distribute advertisements comparable to television. On the other hand, reference numeral 1012 denotes a personal mail reception screen. Since the mail is composed of text data and still images, the data amount is much smaller at each stage, and it does not take much time even when accessed through a narrow-band transmission network. The same applies to personal schedules, account data, and the like, in addition to email. As described above, by separating and transmitting the personal data from the common data, the user can comfortably access the personal data while displaying video data having a large data amount.

FIG. 2 shows a block diagram of a receiving terminal used in the data distribution system according to the embodiment of the present invention. In FIG. 2, reference numeral 201 denotes an RF conversion module which demodulates a signal received from the second server into a digital signal consisting of 0s and 1s. Reference numeral 202 denotes a modem for connecting to the first server. 203 is a central processing unit (CP) of the receiving terminal.
U), 204 are AV decoders for decoding and reproducing video and audio signals, 205 is an operating system, 206 is an image synthesis module for synthesizing a plurality of contents on one screen, and 207 is a storage medium (hard disk). is there. In the storage medium 207,
An application software program 208, common data 209 received from the second server, and personal data 210 received from the first server are stored. Content other than those described above may be stored.

The operation of the receiving terminal configured as described above will be described below. First, the user issues an instruction to the CPU (203) to access personal data. Here, an instruction is issued to the CPU (203) using a remote controller or a keyboard. CPU
(203) receives the instruction and accesses the first server (100 in FIG. 1) via the modem 202. The personal data (e-mail etc.) received in this way is
U (203) is reproduced by driving the application software acquired from the program software 208. Instead of accessing the first server, the content stored as the personal content 210 in the storage medium 207 may be reproduced. When the personal data is accessed, the second data is forcibly and simultaneously received through the second receiving means 108 in accordance with the instruction of the CPU (203), and the received signal is converted to 1 by the RF conversion module (201). It is demodulated to a digital signal consisting of zeros. This signal passes through the CPU (203) and is reproduced by the AV decoder 204 into audio and video signals. The second
Instead of receiving the signal from the server, the content stored in the storage medium 207 as the common content 209 may be reproduced. The personal data and the common data reproduced in this manner are synthesized by the screen synthesis module 206 so as to be displayed on the same screen, and output to the monitor via the line 219.

FIG. 3 shows a flowchart of the first processing of the receiving terminal used in the data distribution system according to the embodiment of the present invention. In step 302, when the user requests access to the first data group as personal data, first,
The CPU (203 in FIG. 2) forcibly starts accessing the second data group. Access to the second data group is step 3
At 11, a second data group serving as common data is received, and the second data group is reproduced as second reproduction data (312) and displayed in the second display area of the screen (313). The reception and reproduction display of the second data group are performed continuously. Step 30 provided that the user has accessed the second server.
Go to 3 and access the first data group (personal data)
(321), and reproduces it as the first reproduction data (3
22) After that, display in the first display area of the screen (3
23). Therefore, the first playback data and the second playback data are displayed on the screen.
Playback data is simultaneously displayed in each display area. The size of the display area at this time can be changed according to the content of the first reproduction data. For example, when the first reproduction data is data indicating a state in which electronic mail is being fetched, the display area of the second reproduction data can be set to be large and displayed. Then, when the capture is completed and the content of the mail is actually displayed as the first reproduction data, the display area of the first reproduction data can be set to be large. The control for changing the size of the display area is performed based on the CPU (217 in FIG. 2).

After the screen is displayed, the access (display) of the second data group is continued, and the data is forcibly displayed on the screen at all times (step 304). That is, the process proceeds so that the reception, reproduction, and screen display of the first data group are performed on condition that the reception, reproduction, and screen display of the second data group are performed (step 307). This series of processing is continuously repeated as long as the reproduction of the first data is not stopped (step 305). When the user stops displaying the first playback data, which is personal data (step 305), the reception of the continuously played second data group is automatically stopped (step 306). In the present embodiment, the processing for the case of receiving and reproducing / displaying the first data group from the first channel is described. However, the first data group is stored in the storage medium (210 in FIG. 2). The same processing as described above can be performed when reproducing and displaying the reproduced data.

FIG. 4 shows a flowchart of the second process of the receiving terminal used in the data distribution system according to the embodiment of the present invention. The basic operation is the same as the processing shown in FIG. The difference is in step 411. In the second processing, the second data group reproduces and displays data stored in the storage medium (209 in FIG. 2). Thus, the second data can be stored in the storage medium in advance and displayed. By performing this processing, for example, when the data corresponding to the first data originally received in the narrow band has a huge data amount, it can be received via the second channel in the wide band. The second reproduction data stored in the storage medium is displayed on the screen.

FIG. 5 shows a flowchart of the third process of the receiving terminal used in the data distribution system according to the embodiment of the present invention. The basic operation is the same as in FIG. Here, the second
After receiving the data, the identification information attached to the second data is extracted and stored (step 514). After the display is stopped, this identification information is sent to the first server (step 506). Since the identification information of the second data group which is continuously received may be different, these are extracted and sent to the first server. In the present embodiment, the channel (third channel) for transmitting the identification information to the first server uses the same channel as the first channel. However, the present invention is not limited to this, and another channel may be used. How to use the identification information will be described later.

FIG. 6 shows a flowchart of the fourth process of the receiving terminal used in the data distribution system according to the embodiment of the present invention. The basic operation is the same as the processing shown in FIG. The different points are steps 606 to 608. At the time of starting the reception, the display start time of the second data group is measured and stored (606). After the display is stopped, the display end time of the second data group is measured and stored (607). Before disconnecting the line, the display start time and the display end time are sent to the first server (608). In this embodiment, the channel (third channel) for transmitting the display start time and the display end time to the first server uses the same channel as the first channel. However, the present invention is not limited to this. Is also good. How to use the display start time and the display end time will be described later.
