Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital data transmission / reception system for transmitting moving image data encoded according to the international standard of ISO / IEC, MPEG-2, etc. for encoding moving image data with high efficiency. The present invention relates to a digital data decoder for decoding and outputting moving image data and a receiver for displaying digital data. In the following, a description will be given of a case where the present invention is applied to digital broadcasting. However, the present invention is not limited to this, and the present invention can be applied to data transmission / reception such as data communication by a similar mechanism.

[0002]

2. Description of the Related Art Due to the large amount of digital moving image data, high-efficiency coding means performs compression to remove redundancy and the like, and then transmits or records the coded moving image data to transmit the data. Alternatively, the recording cost can be reduced. ISO / IEC / JT
The MPEG-2 standardized by C1 / SC29 / WG11 is well known.

In encoding based on the MPEG-2 system, each frame of moving image data is encoded without an I-frame (Intr) which has a frame (reference frame) referred to as a predicted value.
a Picture), P frame (Predictive Picture) that uses only the forward frame in the display order as a reference frame, and B frame (Bidirectional Picture) that uses the forward frame and the backward frame as reference frames. I do. In actual encoding, two reference frames, a forward direction and a backward direction, need to be present at the time of decoding a B frame, and encoding is performed after the frame order is skillfully changed.

In a decoder device, encoded moving image data sent in the order of encoding is sequentially decoded. The decoded data must be temporarily stored in a memory and rearranged so as to follow the display order. Also, the decoded data of the I and P frames need to be used as reference data when decoding the subsequent B frame, and it is necessary to store two frames of moving image data in the memory without fail. The rearrangement of the frame order is performed using the memory for these two frames. Further, since encoding is performed in units of one frame, when one frame is composed of two interlaced fields such as a television signal, even if it is a B frame, it cannot be displayed simultaneously with decoding.
It is necessary to convert the frame data into field data rearranged in the order of the scanning lines. For this purpose, about one frame of memory is required.

An image signal compressed by the MPEG-2 system is
Classified into several categories, especially at the main level
The two categories, called (ML) and high-level (HL), are of particular importance in application.

The main level corresponds to the NTSC system of horizontal 720 pixels × vertical 480 scanning lines × frame frequency 30 Hz, and is adopted in satellite digital broadcasting. The high level is compatible with high-definition images such as 1920 horizontal pixels × 1080 vertical scanning lines × 30 Hz frame frequency, and has been adopted for terrestrial digital broadcasting in the United States for the purpose of providing high-quality broadcasting services. I have decided. Terrestrial digital broadcasting in the United States, for example, Nikkei Microdevices 1997
It is introduced in the monthly issues P47-P53.

[0007] The memory capacity necessary for decoding the encoded moving image data of the MPEG-2 system is equal to the capacity of the above three frames, and an encoded image data buffer for temporarily storing an encoded image at the time of decoding is added. It will be. The capacity of this coded image data buffer (VBV) is 1,835,008 bi at the main level.
t, which is 9,781,248 bits at high level. This capacity value is defined as the minimum capacity that must be maintained so that proper encoding and decoding is guaranteed even with a combination of encoding devices and decoder devices from different manufacturers.
EG-2 method.

[0008] Nikkei Microdevices May 1997 issue P47
As described in P.53, there are a wide variety of image formats of encoded moving image data. Therefore, in order to display the decoded moving image data corresponding to all these image formats on a specific monitor, a display device that can display all these image formats must be used, or a format conversion device must be provided between the decoder device and the display. Must be used. The latter is advantageous for reducing the price of the monitor.

Further, satellite digital broadcasting and terrestrial digital broadcasting are not independent services for users who receive and enjoy these broadcasts. The need to enjoy conventional analog broadcasting on the same television receiver is very natural, and it is necessary to respond to this.

[0010]

SUMMARY OF THE INVENTION Encoded video data which can be used for a receiver of a broadcast service in which the image format of the encoded video data has various image sizes, such as digital terrestrial broadcasting in the United States An example of such a decoding device is disclosed in Japanese Patent Application Laid-Open No. 8-205161. In this example, a high-definition moving image (HD: High Definition) is converted to a standard moving image (SD: Standard Definit
This is a proposal that facilitates compatibility with a plurality of image formats by decoding while downsampling to (ion).

[0011] However, in this example, there is a problem that only high-definition image data can be output as standard image data, and a user cannot enjoy precious high-quality broadcasting. It does not mention anything about the configuration that can receive analog broadcasts at the same time.

An object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to facilitate correspondence to various image formats to be broadcast, and to realize simultaneous reception of analog broadcasts.

[0013]

In order to achieve the above object, the present invention provides a method for decoding moving image data of digital broadcasting, a memory for storing the decoded moving image data, and a method for decoding the moving image data. First on-screen data multiplexing means for mixing the first on-screen data, first image format converting means for format-converting the first on-screen data mixed moving image data, and the format-converted moving image A second on-screen data multiplexing means for mixing the data with the second graphics data is provided to output the second on-screen data mixed moving image data.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of the present invention, in which the present invention is applied to a digital broadcast receiver.
In FIG. 1, 1 is a digital broadcast antenna, 2 is a digital broadcast tuner, 3 is a front end circuit, 4 is a descrambler, 5 is a transport demultiplexer, 6 is a clock generator, 7 is a system controller, 8 is a memory,
9 is a memory interface, 10 is a memory bus, 11 is a video header parser, 12 is a video decoder, 13 is a first on-screen display circuit (hereinafter referred to as an OSD circuit), 14
Is a reformatter, 15 is a second OSD circuit, 16 is a first digital-to-analog converter (hereinafter referred to as DAC), 17 is a monitor drive circuit, 18 monitor, 19 is an audio header parser, 20
Denotes an audio decoder, 21 denotes a second DAC, 22 denotes a speaker drive circuit, and 23 denotes a speaker.

A broadcast wave is received by a digital broadcast antenna 1 and frequency-converted by a digital broadcast tuner 2. The front end circuit 3 demodulates, for example, a received signal that has been 8-PSK modulated, corrects a transmission error using error correction parity, and outputs a transport stream. In the pay stream, the main digital data of the transport stream is scrambled, and key information from the system controller 7 is used as an auxiliary input (detailed connections around the system controller 7 are:
(It is omitted to make the drawing complicated), and the descrambler 4 cancels the scramble. In general, several different programs are multiplexed in the transport stream, and the transport demultiplexer 5 outputs a program desired by the user from the plurality of programs to the system controller 7. Through a program, separates one program, and further separates the encoded video data and the encoded audio data that constitute the encoded moving image data, and separates the respective encoded data into the memory bus 10 and the memory interface. Via 9, it is temporarily stored in a dedicated area in the memory 8. The transport demultiplexer 5 simultaneously separates the multiplexed key information other than the moving image data and the program multiplex table information indicating how the respective programs are multiplexed. Is also sent. These transmissions are performed before one program is separated and selected.

The transport demultiplexer 5
Extracts time information from the transport stream and sends it to the clock generator 6. The clock generator 6 controls an internal timer so that the time of the decoder device becomes the same as that of the transmission side, and generates a clock signal used in the decoder device in synchronization with the timer information. In the drawing, wiring for clock signals is omitted to avoid complication of description.

The encoded video data stored in the memory 8 is read out from the memory 8, the format information such as the image size is obtained as header information by the video header parser 11, and the format information is sent to the video decoder 12 and the system controller 7. Also video header parser 11
Extracts, for example, closed caption subtitle data related to the content of the encoded video data, and sends it to the system controller 7. The video decoder 12 decodes the encoded video data according to the extracted image format information. In the decoding process, the video decoder 12 converts the decoded image data into a predetermined frame of the memory 8 via the memory bus 10 and the memory interface 9. Write to memory area. As described above, the frame memory area is equivalent to three frames, and the I picture and the P picture are read as the image data of the reference frame when decoding the P picture and the B picture. In general, these decoding operations are generated as image data of a frame obtained by combining two fields, whereas the output of the video decoder 12 rearranges the memory in the scanning line order for each field while rearranging the display frame order. The image data is read from the frame memory area 8 and output.

The first OSD circuit 13 mixes on-screen data with the output image data of the video decoder 12.
The on-screen data to be mixed is data processed by the system controller 7 for display from the closed caption subtitle data described above. The data processed for display is stored in the memory 8 before being sent to the first OSD circuit 13 in advance, and each time the first OSD circuit 13 requests data in accordance with output image data, the memory 8 The data is supplied to the first OSD circuit 13 via the interface 9 and the memory bus 10, and the output image data and the on-screen data are mixed and synchronized. Further, the mixed image data is supplied to the reformatter 14.

FIG. 2 is a block diagram of the reformatter 14 for converting the image format. In FIG. 2, 141, 142,
Reference numerals 143 and 144 are selectors for selecting and outputting any one of three inputs A, B and C. 145 is a memory controller,
146 is a horizontal size converter, and 147 is a vertical size converter. The selectors 141 to 144 control which of the inputs A, B and C is selected by the system controller 7 in accordance with the ratio between the image size of the encoded video data and the image size displayed on the monitor 18 described later. .

FIG. 3 is a diagram for explaining the operation mode of the reformatter 14. As a format of image data to be displayed on the monitor 18, a horizontal 1920 pixels (effective portion), a vertical 1080 lines (effective portion), well-known as a high-definition image (HDTV),
It assumes a frame frequency of 30 Hz, 2: 1 interlaced scanning, and a screen aspect ratio of 16: 9. The figure shows the respective size conversion coefficients in the horizontal size converter 146 and the vertical size converter 147 and which input is selected by the four selectors. For example, the image size of the input to the reformatter 14 which is the output of the first OSD circuit 13 is 3
In the first row of horizontal 1280 pixels × vertical 720 scanning lines, if the screen aspect ratio is 16: 9 and the frame frequency is 60 Hz, and the progressive format is 60 Hz, the horizontal size conversion ratio is (3/2) times and the number of pixels is from 1280 pixels. The image data is converted into 1920 pixels, the vertical size conversion ratio is set to (3/4), and the 720 scanning lines are converted into 1080/2 scanning lines. Furthermore, in order to convert progressive to interlaced, each of the 60 Hz frames is associated with a field, and the phases between the scanning lines of the two fields are made different.

The reformatter 14 is a memory controller
The memory 8 is used via the memory bus 10 or the like in order to output the format-converted image data at a predetermined data rate. Selectors 141 to 144 are provided so as to minimize the used capacity of the memory 8 and the data bandwidth of the memory bus 10. That is, the horizontal size converter 14
6 and the vertical size converter 147, the selectors 141 to 144 are controlled so as to be arranged before the memory controller 145 when the conversion ratio is smaller than 1, and conversely when the size conversion ratio is larger than 1. , Are arranged after the memory controller 145.

In the above example, the vertical size conversion coefficient is 1
Therefore, the selector 143 selects A, inputs the input image data to the vertical size converter 147, and selects the C so that the output becomes the input of the memory controller 145.
And write it to the memory 8. Thereafter, the readout is performed so as to meet the predetermined rate. The image data read from the memory 8 is output from the memory controller 145, and is input to the horizontal size converter 146 when the selector 142 selects B. The horizontal size converter 146 is arranged after the memory controller because the size conversion ratio is 1
Because it is bigger. If both size conversion ratios are greater than 1, both the vertical size converter 147 and the horizontal size converter 146 are located after the memory controller 145, but the vertical size converter 147 is Place before 146. This is effective in reducing the size of a line buffer (not shown) in the vertical size converter 147. For the same reason, both the size conversion ratios are less than 1 and the vertical size converter 147 and the horizontal size converter 146
Are placed before the memory controller 145, the horizontal size converter 146 precedes the vertical size converter 147. Returning to the example case, finally, the selector 144 selects the output of the horizontal size converter 146 (selects B), and uses the output of the reformatter 14.

Returning to FIG. 1, the description will be continued. The output of the reformatter 14 is input to the second OSD circuit 15. The second
The second OSD circuit 15 mixes graphics data such as a program guide with input image data. The output of the second OSD circuit 15 into which the graphics data has been mixed is converted into an analog signal by the first DAC 16 and displayed on the screen of the monitor 18 via the monitor drive circuit 17.

The graphics data to be mixed by the second OSD circuit 15 is generated by the system controller 7 and stored in the memory 8 in advance.
Are read from the memory 8 based on an instruction from the system controller 7. For example, in the case of a program guide, the content of the character code is converted to graphics data according to the program multiplex table information separated from the transport stream by the demultiplexer 5 and mixed with the background graphics. Generate. The graphics data mixed by the second OSD circuit 15 conforms to the image format of the output of the reformatter 14, and is not the image format of the encoded video data decoded by the video decoder 12. For this reason, the graphics data such as characters can be displayed on the monitor 18 without undergoing any large processing thereafter, and high-quality graphics data can be displayed. The program guide is used when the user selects a program, and the ability to display graphics data of high-quality characters leads to a high-quality user interface.

The encoded audio data is read from the memory 8 by the audio header parser 19. The audio header parser 19 specifies an encoding method, detects synchronization information from the encoded audio data, extracts audio parameters such as a sampling frequency, and notifies the audio data coder 20 of the information. The audio decoder 20 decodes the encoded audio data using these audio parameters to obtain audio data. The decoded audio data is converted to an analog audio signal by the second DAC 21 and is output to the speaker
Output from 23.

According to the embodiment described above, by appropriately setting the operation setting of the reformatter 14 based on the image format of the encoded video data, a plurality of image formats can be converted into one image format and monitored. 18 can be displayed. This means that the monitor
18 scanning deflection circuits (not shown) can be simplified,
This helps to reduce the cost of the entire receiver. Also, a decoder device for encoded moving image data (first and second DACs 1 from antenna 1).
6 and 21) and the monitor drive circuit 17, the monitor 18, and the speaker drive circuit 22 and the speaker 23 are provided as separate devices, the output of the decoder device for the coded moving image data is set to the current analog broadcast. By setting the same image format, it is possible to use a conventional analog broadcast receiver as a monitor device.

Further, in this embodiment, two OSD circuits (13, 1
5) It is possible to multiplex the program-specific information suitable for display in the image format of the coded video data to be broadcast and the on-screen display information for improving the user interface into separately decoded image data. This is also useful for displaying on the monitor 18 in one image format.

Next, a second embodiment of the present invention will be described with reference to FIG. However, in FIG. 4, those having the same reference numerals as those in FIG.
Perform only the differences from.

In FIG. 4, a second reformatter 24, a third DAC 25, a recording output circuit 26, and a recording device 27 are added to the first embodiment of FIG.

The configuration of the second reformatter 24 is also the same as that of the first reformatter described with reference to FIG. This second reformatter converts the output image format to the same SDTV as the analog broadcast regardless of the image format of the encoded video data, and outputs it to a recording medium such as a video tape via a DAC.

FIG. 6 is different from the second embodiment of FIG. 4 in that a down mixer 28 and a fourth DAC 29 are added. The down mixer 28 is for down-mixing, for example, 3 / 2-system multi-channel audio data to be decoded by the audio decoder 20 to 2CH or monaural audio data. Extract the optimal parameters of the mix and downmix accordingly. The downmixed audio data is sent to the recording output circuit 26 via the fourth DAC 29, and is recorded by the recording device 27 together with the video signal.

In this embodiment, the downmix parameter specified by the broadcasting station can be faithfully reflected, and high-quality recording can be performed.

As a modification of the present embodiment, a down-mixed audio signal output from the down mixer 28 and the fourth DAC 29 may be supplied to the speaker drive circuit 17. In this case, the second DAC 21 is unnecessary,
Since the number of the speakers 23 can be reduced as compared with the number corresponding to each of the multi-channels, the cost of the receiver can be reduced.

Next, a fourth embodiment of the present invention will be described with reference to FIG. As in the description so far, the description of what has already been described is omitted.

In FIG. 7, 30 is an analog broadcast antenna, 31 is an analog broadcast tuner, 32 is an NTSC decoder, 33
Is an input processor. The analog broadcast antenna 30 and the analog broadcast tuner 31 are for receiving a conventional analog broadcast. If the user selects to display the video signal that has received the analog broadcast on the monitor 18, the system controller 7 is notified via an appropriate user interface (for example, a remote control device not shown), To a new block. In this mode, the analog broadcast signal received by the analog broadcast antenna 30 and frequency-converted by the analog broadcast tuner 31 is converted into a component by the NTSC decoder 32.
(To separate the luminance signal and color difference signal). The component signals are input processor 33, selector 4
0, the data is stored in the memory 8 via the memory bus 10 and the memory interface 9 via the reformatter 14. As described with reference to FIG. 4, the drive circuit 17 and the monitor 18 of FIG. 7 may be replaced by an output circuit 26 and a recording device 27 to form a built-in VTR, or the DAC 16, the drive circuit 17 and the monitor 18 of FIG. 26, the internal DVD may be replaced with the recording device 27. These figures are shown in FIGS.

FIG. 8 shows an NTSC decoder 32 and an input processor.
34 is a configuration diagram of FIG. In FIG. 8, 321 is a comb filter, 322 is a color decoder, 323 is a luminance signal delay circuit, 32
4 is a sync separation circuit, 331, 332, and 333 are first to third analog-to-digital converters (hereinafter, referred to as ADCs), 334 is a multiplexer, 335 is an analog clock generator, 336 is an enable signal generator, and 337 is It is an address generator.

The analog video signal input from the analog broadcast tuner 31 is a composite signal obtained by multiplexing a luminance signal and two color difference signals, as is well known. The format of this composite signal is NTSC used in Japan and North America.
Method and PAL method used in Europe (excluding France), France,
There is a SECAM method used in Russia. In this figure, NTSC
Although the case of the system is described, it goes without saying that the present invention is not limited to the NTSC system and can be applied to the PAL system and the SECAM system. The NTSC signal input from the analog broadcast tuner 31 is separated into a luminance signal and a chrominance signal by a comb filter 321, and the chrominance signal is
For example, two color difference signals called (RY) and (BY) are generated. On the other hand, the luminance signal is delayed by a luminance signal delay circuit 323 between the two color difference signals. The sync separation circuit 324 detects horizontal and vertical sync signals of the NTSC signal. The color difference signal, the luminance signal, the horizontal and vertical synchronization signals are output to the input processor 33.

An analog clock generator 335 of the input processor 33 multiplies the horizontal synchronizing signal to generate a clock signal of, for example, 13.5 MHz. The clock signal is output from three ADCs
The color difference signals and the luminance signals supplied to the ADCs 331 to 333 are converted into digital data. The color difference signal and the luminance signal converted into digital data are supplied to the multiplexer 334. Also, the input processor 33 includes
A digital clock generated by the clock generator 6 of the decoder device is also supplied. The digital clock has a higher frequency than the clock signal generated by the analog clock generator 335, and has a frequency of 54 MHz or 81 MHz, for example, but is synchronized with the image data of the encoded bit stream of the transport stream. In general, the clock signal generated by the analog clock generator 335 is not synchronized with the clock signal. The digital clock is supplied to a multiplexer 334, an enable signal generator 336,
Input to the address generator 337.

The enable generator 336 receives the clock signal generated by the analog clock generator 335, and outputs three ADs during one digital clock cycle.
An enable signal is generated at a timing at which digital data output from C331 to 333 can be determined. In particular,
81 MHz is six times 13.5 MHz, but since the frequency is not synchronized, 5 to 7 rising edges of the 81 MHz digital clock are included in one cycle of 13.5 MHz. The enable signal is 81 MHz in one cycle of 13.5 MHz.
A data determination period of one cycle period of z is shown. Using the enable signal, the multiplexer 334 takes in the color difference signal and the luminance signal converted into the digital data by the digital clock, and performs asynchronous-synchronous clock conversion. The enable signal is also supplied to an address signal generator 337, which generates and outputs an address signal corresponding to the screen position of the digital data multiplexed by the multiplexer 334. As a result, it becomes possible to process an analog broadcast signal that is not synchronized with the transport stream transmitted by digital broadcast using the digital clock. Note that the input processor 33 shown in FIG. 8 shows a case where the digital signal is multiplexed, but some or all of the luminance signal and the chrominance signal are multiplexed in the form of an analog signal, and this is digitally converted. Then asynchronous with the digital clock timing
There is also a method of performing synchronous clock conversion.

Returning to the description of FIG. 7, the image data to be stored in the memory 8 is selected by selecting whether the image displayed on the monitor 18 is digital broadcasting or analog broadcasting. In the case of digital broadcasting, the image data is decoded by the video decoder 12, and in the case of analog broadcasting, the image data is digitally converted by the input processor 33. These are switched by the selector 40, input to the reformatter 14, and converted into an image format suitable for the monitor 18,
The image is displayed on the monitor 18 via the second OSD circuit 15 and further via the first DAC 16 and the monitor drive circuit 17. When displaying image data by analog broadcasting, reading of image data from the memory 8 by the reformatter 14 is performed by the digital clock, and is performed based on horizontal and vertical synchronization signals generated by the digital clock. A function as a frame synchronizer is realized in a series of operations of fetching moving image data by the input processor 33 and writing and reading from the memory 8 by the reformatter 14.

As for the audio signal, both a digital broadcast audio signal obtained by decoding by the audio decoder 20 and an analog broadcast audio signal obtained from the analog broadcast tuner 31 are supplied to the speaker drive circuit 22 to select image data. Is selected, and sound is output from the speaker 23.

In the present embodiment described above, since both digital broadcasting and analog broadcasting can be displayed on the same monitor 18, a receiver compatible with analog broadcasting and digital broadcasting can be realized.

The present embodiment differs from the fourth embodiment in that both the image data obtained by digitally converting the analog broadcast video signal and the image data obtained by decoding the coded video stream of the digital broadcast by the video decoder 12 are stored in the memory 8. To be stored. The first reformatter 14 converts the digital broadcast image data into an arbitrary image format using the memory 8. Further, the third reformatter 34 has a frame synchronization function of converting image data of analog broadcasting into the same horizontal and vertical synchronization signals as image data of digital broadcasting, and these two image data are
Synthesized by the mixer 35. The synthesized image data is the first
Via a DAC 16 and a monitor drive circuit 17 to be displayed on a monitor 18.

Specifically, a window is provided at an arbitrary position of the full-size digital broadcast reception image, and a reduced analog broadcast reception image is inserted into the window, or the digital broadcast reception image and the analog broadcast reception image are reversed. Alternatively, two windows of approximately the same size are provided in the TV screen, and a digital broadcast received image and an analog broadcast received image can be displayed in each window.
