Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-media communication output device, and in particular, it is used for various services in which a plurality of information media such as voice and characters / videos are simultaneously handled and provided as one piece of information. The present invention relates to a multi-media communication output device.

2. Description of the Related Art Most of communication devices that handle a plurality of information media handle characters and images. Despite the fact that it handles multiple media, each media is under its own control, displaying characters and calling up images as needed. In communication devices such as videophones that simultaneously handle voice and other temporally continuous information media and other information media, image media have also been treated as temporally continuous. For example, the same applies to Captain Service Videotex,
There is no example in which audio information and image information are used while being controlled synchronously.

[0003]

From the above, it is intended to provide the multimedia information in which the audio information and the image information are synchronized by executing the switching, the change and the other control of the image information every moment. In this case, it is necessary to establish a method for instructing this switching and change. To this end, it must be taken into consideration that there are two types of request factors for changing image information. One of them is to switch the screen at an arbitrary time like a picture-story show, and the other one is to execute an expression, a color change and other controls with respect to time like drawing information. It is necessary to establish methods corresponding to each of these.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the amount of data required to perform synchronization control in a device that handles a plurality of information media will be described. Here, it is assumed that the color change is performed in the coordinate of the size of X in T time. If the coordinate value bx bit is given for each time t, the total data amount is T.bx / t bit (1).

On the other hand, if it is assumed that time bt bits are given for each distance x, the total data amount is Tbt / x bits (2). A comparison of the two ratios gives T / t.x / X.bx / bt (3).

For example, if a color change for 10 seconds is instructed every 1/30 second, the total amount of data is 3 according to equation (1).
It becomes 00. If a normal personal computer screen (horizontal × vertical = 640 dots × 480 dots) is instructed laterally for each dot, equation (2) becomes 1/640. Since equation (3) is expressed in bits, in this case,
It becomes 10/9 or 9/8. Therefore, this ratio is 1 /
This method is adopted because the value becomes close to 2 and the amount of information is smaller when the coordinate value is given at every constant time.

On the other hand, when switching images at an arbitrary time such as a picture-story show, as in the previous example, the accuracy is 1/30 second, and 10
Assuming that the image is switched after 2 seconds, a bit indicating whether to switch every 1/30 second is set, and a method that requires 300 bits is compared with a method in which a value of 300 is given by 9 bits. It is advantageous to give instructions.

When the image information medium is changed in synchronization with the audio information medium, the amount of data is reduced by changing the image information by transmitting and receiving the synchronous data corresponding to the request element of each image information. You can An embodiment of the present invention will be specifically described with reference to FIGS. FIG. 1 shows a karaoke apparatus for playing a karaoke piece having two different request elements for image information.

The information on the requested music is supplied from the central station to the karaoke apparatus via the communication line and input via the communication control section 1. The music information includes music information, lyrics information, still image information on the background, and synchronization control information. Since the lyrics and still images need to be displayed along with the music, they need to be transmitted slightly ahead of the music. The lyrics information, the still image information, and the synchronization control information for controlling them are accumulated in the file unit 2, and the music information is output as it is received via the audio output unit 3. If this music information is also stored, the same music can be reproduced many times.

The lyrics information accumulated in the file unit 2 is supplied to the screen combining unit 6 via the screen switching control unit 4 and the color control unit 5, while the still image information is displayed on the screen via the still image switching control unit 7. The information is supplied to the synthesizing unit 6, and both pieces of information are synthesized by the screen synthesizing unit 6 and output to the screen. At this time, the synchronization control information is decoded by the synchronization control unit 8 to control the screen switching control unit 4, the color control unit 5, and the still image switching control unit 7, respectively, so as to realize an output synchronized with the music information. I am configuring.

An example of the data structure of the synchronization control information will be described with reference to FIG. A number is attached to each segment of the lyrics information and the still image information. For the still image information to which the still image information number “N” is attached, the lyrics information number “n1” “n2” ... There is corresponding numbered lyrics information. Since it is more efficient to control the still image information by the display switching time as described above, the timing of the still image information "N" is determined by the relative time taken into consideration from the reference time when the music information is started. Similarly, in the lyrics information, the timing of the lyrics information “n1”, “n2”, ... Is determined by the relative time in consideration of the time when the music information is started. In this case, the reference time may be set as the start time of the still image information “N”, but it is necessary to pay attention to the accumulation of error and is not recommended.

Next, regarding the case where the color of the displayed lyrics is changed in accordance with the music, in this case, instead of showing the change time of each display pixel, the change amount per unit time is used as the coordinate value. I'm giving. As a method of giving the coordinate value, if there is no visual problem, for example, the coordinate value is given every 1/10 second, and when displaying, the color control unit 5 proportionally divides at every 1/30 second. As a display,
The amount of data can be further reduced.

The multi-media communication output device according to the present invention can be used for various services for providing a single piece of information that simultaneously handles a plurality of information media such as voice and characters / video. For example, online catalog sales, telephone shopping and other product introductions / commercial, language learning and other correspondence education, matchmaking, company introduction and other human resource company introduction, karaoke, simple VIDE
It can be used for services by multiple information media such as O and other leisure or amenities.

[0015]

As described above, according to the multi-media communication output device of the present invention, it is possible to reduce the amount of data for performing synchronous control in a system that handles a plurality of information media, and it is necessary for transmission and storage. It is possible to reduce the amount of information said to be small. This further shortens the preparation time until the information is output, and improves the efficiency of the related communication system.
