[2] Method of Inserting URL Information into VBI Next, an example of a method of inserting URL information into the VBI will be described with reference to FIGS.

In the case of an NTSC signal, VBI corresponds to lines 10 to 21 of an odd field and lines 273 to 284 of an even field. However, there is a case where a part of the effective screen is used.

URL information may be inserted anywhere in these VBIs. For example, it may be carried in a terrestrial data broadcast signal of the tenth to thirteenth lines, or may be carried in a video ID signal used in a package system. Here, a method for carrying the video ID signal will be described.

As shown in FIG. 4, the video ID signal includes a reference signal (Ref) of 70 IRE and a 20-bit signal represented by an amplitude 70 IRE or 0 IRE in an effective video portion of the 20th and 283rd lines of the VBI of the luminance signal. , And this 20-bit digital signal is encoded and transmitted as an identification signal. In principle, the same information is transmitted to the 20th line and the 283rd line. The clock frequency fc is fc = fsc / 8 = 447 kHz. Here, fsc is a color subcarrier frequency.

The 20 bits of the identification signal shown in FIG. 4 include word 0 (bit 1 and bit 2), word 1 (bit 3 to bit 6), and word 2 (bit 7 to bit 14) as shown in FIG. , And CRCC (bit 15 to bit 20)
It is composed of Then, two bits of word 0 represent the aspect ratio of the screen, and four bits of word 1 represent a header indicating 16 types of information transmitted in word 2. Here, as shown in FIG. 6, the header of word 1 is “1”.
000 "indicates a category code header, and" 100 "
"1" indicates the header of the upper data of the control code or the character code, and "1010" indicates the header of the lower data of the control code or the character code. The 6-bit category code shown in FIG. Here, “001100” which is not defined in FIG. 7 is newly defined as indicating URL information.

FIG. 8 shows an example of transmitting URL information. First, in the first frame shown in FIG.
Bit 6 (word 1) transmits the header "1000" indicating the category code, bit 7 transmits the character information channel number (here, channel 1), and bit 8 to bit 13 the URL. The category information indicating the information is transmitted, and subsequently, the odd parity code “0” is transmitted in bit 14.

Next, in the second frame shown in FIG. 8 (b), the header "1001" indicating the upper character code is transmitted by bits 3 to 6, and the character "" is transmitted by bits 7 to 13. "110001" indicating the upper data of "h"
Then, the bit 14 transmits an odd parity code “0”.

Next, in the third frame shown in FIG. 8 (c), "1010" which is a header indicating a lower-order character code is transmitted by bits 3 to 6, and then the characters "7" to "13" are transmitted by bits 7 to 13. "000101" indicating lower data of "h"
A 1 is transmitted, followed by an odd parity code "0" in bit 14.

Similarly, in the fourth to seventh frames shown in FIGS. 8D to 8G, data indicating the character "t" is transmitted twice consecutively. Thereafter, similarly, URLs sequentially displayed on the screen (for example, “http: //www.some.
com / ") is transmitted.
In each frame, bit 1 and bit 2 transmit aspect information, and bit 15 and bit 20 transmit CR.
CC (Cyclic Redundancy Check)
Code).

[3] System for Processing URL Information (1) Television Broadcasting Transmitter FIG. 9 shows a system for inserting URL information into VBI on the television broadcast transmitting side. Here, when outputting an image such as a commercial, the image source 11 performs processing so that the URL is displayed on the screen. URL encoding device 12
Creates URL information as shown in FIG. VBI
The inserter 13 inserts the URL information output by the URL encoding device 12 into the 20th and 23rd lines of the video signal output by the video source 11. The video signal into which the URL information has been inserted in the VBI inserter 13 modulates a carrier in a modulator 14. This modulated video signal (a signal obtained by modulating a carrier with a video signal) is mixed with a modulated audio signal (a signal obtained by modulating a carrier with an audio signal) in an audio mixer 15 and frequency-converted and amplified by a transmitter 16. Thereafter, the signal is transmitted from the transmission antenna 17 by radio waves.

The URL information encoded by the RL encoding device 23 is converted into the VB of the video signal output from the detection unit of the tuner 21.
Of the I, the URL is inserted into a VBI different from the VBI in which the URL information is inserted on the transmission side. For example, a terrestrial data broadcast signal cannot be recorded / reproduced by a video cassette recorder because of its high frequency. Therefore, by replacing the signal with a signal having a low transmission rate such as a video ID, the URL information can be stored in the video cassette recorder. In addition, even when various data such as digital broadcasting comes in the data area on the bit stream, after decoding the URL information from the various data, the URL information can be encoded and put on the VBI.
