Description

ASI Switcher for digital advertisement inserter

The present invention relates to an asynchronous serial interface switcher for inserting advertisement data into digital broadcast data to generate and output new broadcast data. In particular, the advertisement data can be inserted at the TS level without decoding the digital broadcast data to the audio / video level. Asynchronous serial interface switcher for digital advertisement inserter to make.

Digital conversion of terrestrial broadcasting is underway to be completed by 2012. In conjunction with the digital conversion of terrestrial broadcasting, cable broadcasting stations are urgently required to introduce a system for digital broadcasting services. Digital conversion of cables means everything from manufacturing, transmission and transmission.

Cable broadcasting transmits a cable channel of a program provider (PP) based on mandatory retransmission of terrestrial broadcasting. For the profitability of the cable, more than 50% of the total channels are sent by inserting local advertisements into program providers' channels as advertising revenue sources.

In this case, an advertisement inserter is required and an asynchronous serial interface switcher (ASI Swithcer), which is an important equipment of the advertisement insertion system, is required for channel retransmission because the transport stream is compressed digitally and not an analog signal. to be.

Therefore, the system is complicated by the processing of the compressed multimedia stream while converting the processing from the video switcher to digital as in the conventional analog broadcasting.

In particular, in analog broadcasting, video sync is detected by switching the video to a frame and digital broadcasting cannot be applied to analog broadcasting. Because digital broadcasting transmits a broadcast stream in a compressed transport stream (TS), it is necessary to decode the compressed TS data in order to detect video sync. It becomes impossible to detect.

However, since TS data is compressed data, many technical difficulties exist for accurate switching, such as analog data.To date, a known type of TS decodes and transfers TS data input from a plurality of sources. This is how you encode it.

1 is a schematic configuration diagram of an apparatus for inserting advertisement data into digital broadcast data processed in a manner known to date.

The operation of the asynchronous serial interface switcher using the advertisement inserter according to the prior art of FIG. 1 will be described in detail.

The data represented by Source A is called digital broadcast data 101 generated by the program provider, and the data represented by Source B is called advertisement data 102. The first switcher input unit 111 and the second switcher input unit 112 are respectively input.

The present invention relates to digital broadcasting. The data generated from the source A 101 and the source B 102 are all data compressed in a transport stream (TS) format.

Therefore, in order to merge transport streams, compressed data must be decompressed, that is, decoded.

Specifically, digital broadcast data is input to the first decoder 121 to decode data including video, audio, and control information. In the above, the decoding means decoding in a form output through an image device. Data decoded by the first decoder 121 includes video, audio data, and control information, and the video and audio data are separated by the first demux 131 to be synthesized in the switcher.

In the same way, the advertisement data is also compressed and must be decoded, and the data including video, audio and control information is decoded by the second decoder 122. Meanwhile, the data decoded by the second decoder 122 includes video, audio data, and control information. The video and audio data are separated by the second demux 132 to be synthesized in the switcher.

In order to transmit an advertisement during normal broadcasting in digital broadcasting, advertisement data is inserted into digital broadcasting data that is currently being broadcast. Therefore, the digital broadcasting video stream 141 and the digital broadcasting audio stream 142 of the decoded digital broadcasting data are switchers. Video data and audio data for digital broadcast data input to the 190 and the decoded commercial data 143 and the commercial audio stream 144 are input to the switcher 190 and extracted from the broadcast data by the switcher. The video data and the audio data for the advertisement data extracted from the advertisement data are switched to generate new composite video stream 451 and synthetic audio stream 152 for digital broadcast data.

In this case, new control information for new digital broadcast data is generated. In this case, information included in the existing broadcast data and advertisement data is ignored and new control information is generated based on the newly generated digital broadcast data.

The data generated in this way is a composite of broadcast data and advertisement data and is not distinguished from the receiver's point of view.

The newly generated broadcast data is newly compressed by the encoder 160, and generates a transport stream according to a procedure of generating a synthetic transport stream 170 from a program provider, etc., and regenerates for connectivity with broadcast data currently being transmitted. (Regeneration) After being converted in the device is output through the switcher output unit 180 is transmitted to the receiver through a conventional broadcast system.

However, the asynchronous serial interface switcher according to the related art switches the broadcast data and the advertisement data decoded into the video / audio of the digital broadcast data and the advertisement data in a certain order to generate a new composite video / audio stream, and then re-encodes them. Therefore, when the broadcast time is broadcast in real time because the synthesis transport stream has to be generated, there is a problem that the delay is increased to a level that cannot be ignored.

In addition, since the decoded data must be decoded and then re-encoded, image quality deterioration inevitably occurs due to data loss during decoding and encoding. In particular, image quality deterioration becomes more severe according to the performance of the encoder.

The present invention has been proposed to solve the above-mentioned problems, and the digital advertisement inserter capable of inserting advertisement data without decoding the digital broadcast data into audio / video in inserting and transmitting the advertisement data into the digital broadcast data. We want to provide an asynchronous serial interface switcher.

The present invention has been proposed to solve the above problems, and the digital broadcast data can be stably synchronized with the audio stream and video stream while minimizing the deterioration of the quality of the digital broadcast data in inserting and transmitting the advertisement data into the digital broadcast data. We want to provide an asynchronous serial interface switcher for the ad inserter.

The present invention has been proposed to solve the above-mentioned problems. In the case of inserting and transmitting advertisement data into digital broadcast data, the delay time between inserting advertisement data into digital broadcast data and generating new digital broadcast data is minimized. We want to provide an asynchronous serial interface switcher for digital ad inserter.

Hereinafter, a configuration operation of the asynchronous serial interface switcher for the digital advertisement inserter according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a data flow diagram illustrating a process of generating broadcast data from digital broadcast data and advertisement data in an asynchronous serial interface switcher for a digital advertisement inserter according to the present invention.

The transport stream of Sorce A 211 is called digital broadcast data generated by the program provider and is input through the first switcher input unit 221, and the transport stream of Source B 212 is an advertisement generated by the advertisement provider. The data is input through the second switcher input unit 222.

In order to output an advertisement during broadcasting in digital broadcasting, advertisement data should be inserted in the broadcast data. The present invention proposes a method that does not need to decode a transport stream.

To this end, as shown in FIG. 2, the broadcast video stream 241 and the broadcast audio stream 242 are separated from the digital broadcast transport stream by the first TS-Demux 231, and then a concatenated portion ( The broadcast video stream 243 and the broadcast audio stream 244 from the digital broadcast transport stream by means of a second TS-Demux 232, and then a splicer. , And the composite video streams 261 and 262 and the composite audio streams 263 and 264 concatenated at the concatenation unit are generated.

The concatenated composite video streams 261 and 262 and the synthesized audio streams 263 and 264 are multiplexed like the modified control information described below, and are outputted through the switcher output unit 270 and transmitted to the receiver.

The concatenated composite video streams 261 and 262 and the synthesized audio streams 263 and 264 are decompressed in a manner different from the conventional technique of generating data of the decompressed video stream and the audio stream into one new broadcast data. This means that the video and audio streams are not concatenated together.

On the other hand, the receiver cannot decode it simply by concatenating the uncompressed video stream and the audio stream as described above.

Specifically, control information about broadcast data is included to normally decode a transport stream included in broadcast data, and control information about advertisement data is included to normally decode a transport stream included in advertisement data. It is.

If the broadcast data is transmitted alone, the receiver can decrypt the broadcast data by decoding the control information included in the broadcast data.

However, when the advertisement data is inserted in the broadcast data and then concatenated in detail, the broadcast data can be decoded when the control information of the broadcast data is decoded, but the advertisement data cannot be decoded, so the receiver cannot decode the received data. .

Similarly, decoding the control information of the advertisement data may allow the advertisement data to be decoded but not the broadcast data.

Therefore, in order to decode both the broadcast data and the advertisement data, the receiver must receive both control information of the broadcast data and the advertisement data.

On the other hand, even if the receiver receives both control information of the broadcast data and control information of the advertisement data, the receiver may not normally decode the received broadcast data and the advertisement data depending on the situation.

Specifically, it is known that the decoder malfunctions in the following cases.

First, the PCR (Program Clock Reference) suddenly changes. PCR is a time information referred to by a transport stream and is used to express content in which an audio signal combined with an image is synchronized to the image. When the PCR included in the broadcast data and the advertisement data is different, the broadcast data is decoded. If the decoder wants to decode the advertisement data, the decoder may malfunction due to a sudden change in PCR.

It is also known that the decoder may malfunction even when the PID (Packet ID) of the video or audio suddenly changes. The PID is information regarding a packet ID of 188 bytes in which a header, that is, broadcast data other than control information, that is, video or audio data is included in the transport stream.

PID 0 is an ID reserved by PAT (Program Associstion Table). This PAT has PID of packet called PMT (Program Map Table) inside.

The PMT also contains information that points to the video / audio's PID, so decoders first look for a packet with a PID of 0 and discard any other packets until it finds a PID of 0.

When the PAT with PID 0 comes in, it is analyzed to know the PID of the PMT, and now it waits for a packet with the PID of the PMT. Of course, the data is discarded until it comes in.

After that, when the packet with the PID of PMT comes in, it is analyzed and finally the PID of the video packet and the PID of the audio packet are obtained. From this point, packets that enter the video PID decode the video and packets that enter the audio PID decode the audio.

However, since the broadcast data and the advertisement data have different PATs and PMTs, the decoder which decodes the broadcast data predicts and decodes information on the next received packet according to the PAT and PMT.

However, at the moment of decoding the advertisement data, the packet cannot be decoded because it does not match the previously known information on the PAT or PMT. Alternatively, the advertisement data can be re-analyzed to find the PID of the PMT and then the ID of the PMT. It is necessary to receive and analyze the packet in order to be able to decode the received packet normally. In this case, since the advertisement data may not be a complete data such as broadcast data, that is, a packet having PID 0 may be omitted. It may not be possible to decode the advertising data.

Accordingly, in order for the receiver to receive a signal obtained by combining the broadcast data and the advertisement data and to decode normally, each control information needs to be adjusted to be decodable.

3 is a control information flow diagram for a process of generating control information of digital broadcast data and advertisement data concatenated from control information of digital broadcast data and advertisement data in an asynchronous serial interface switcher for a digital advertisement inserter according to the present invention.

As shown in FIG. 3, the asynchronous serial interface switcher for the digital advertisement inserter according to the present invention is broadcasted by the first TS-Demux 331 when Source A 311, which is broadcast data, is input from the first switcher input unit 321. The broadcast video / audio stream 341 and the broadcast control information 342 are separated from the data.

Similarly, when the source B 312, which is the advertisement data, is input from the second switcher input unit 322, the advertisement video / audio stream 343 and the advertisement control information 344 are output from the advertisement data by the second TS-Demux 332. Are separated.

The separated broadcast video / audio stream 341 and the advertisement video / audio stream 343 are concatenated and separated at the junction 360 to be generated as new synthetic broadcast / advertisement data (GOP, Group of Packet, 361), Control information 351 of broadcasting data (eg, PAT-A, PMT-A, ETC-A) and control information 352 of advertising data (eg, PAT-B, PMT-A, ETC-A) are cross-referenced. Synthesized control information 370 such as PAT-a, PAT-b, and the like so that the control information of the previously broadcasted data is continuous so that the sudden PID, PCR, etc. are not changed compared to the broadcasted data. PMT-a, PMT-b, ETC-a, ETC-b) have been modified to combine the broadcast and commercial video and audio streams of the broadcast and commercial video to the TS-Mux 438 shown in FIG. And the synthesized transport stream is synthesized by the TS-Mux 438 to generate a synthesized transport stream, and then transmitted to the receiver through the switcher output unit 380.

4 is a schematic configuration diagram of an asynchronous serial interface switcher for generating control information of digital broadcast data and advertisement data concatenated from control information of digital broadcast data and advertisement data in an asynchronous serial interface switcher for a digital advertisement inserter according to the present invention. to be.

The asynchronous serial interface switcher for the digital advertisement inserter according to the present invention includes at least two switcher inputs 411, 412, and 413 to receive at least two transport streams.

At least one of the at least two transport streams includes advertising data, and at least one of the at least two transport streams includes digital broadcast data supplied from a program provider.

Transport streams input through the respective switcher inputs 411, 412, and 413 are connected to video streams and audio streams by TS-Demux 421, 422, and 423 connected to the switcher inputs 411, 412, and 413. The video stream and the audio stream are separated into control information, and the video / audio stream storage unit 431 and the control information are stored in the control information storage unit 432.

A video stream and an audio stream of the video stream and the audio stream and the control information separated by the respective TS-Demux stored in the video / audio stream storage unit 431 and the control information storage unit 432 are connected to each other. Concatenated by 434 and then divided into composite packets of a GOP. When divided into the synthesized packet may be divided into units used in generating a conventional transport stream.

Specifically, the video stream can be divided by scene even if it is compressed because the first-in-first-out (FIFO) buffer can buffer about 30 frames.

When the digital broadcast video stream is being output through the switcher, and the cuetone input unit 414 receives the transfer signal for switching to the advertisement video stream, when the output of the currently output broadcast video stream is terminated, the switchover is switched to the advertisement video stream. At this time, the state of the advertisement video stream is checked to determine whether the current frame is an I, B, or P frame. When the I frame is detected, the output of the broadcast video stream is stopped and the I frame of the advertisement video stream is output.

That is, in the concatenation unit 430, the broadcast video stream and the advertisement video stream are identified and concatenated with the broadcast video stream to generate a synthesized video stream. Create a video stream.

On the other hand, since the audio stream is normally connected immediately after the data, no problem occurs. Therefore, the audio stream may be changed from the broadcast audio stream to the advertisement audio stream immediately after receiving the transfer signal, or the advertisement audio stream may be concatenated when the I frame is concatenated. .

In addition, the control information stored in the control information storage unit 432 is converted by the respective control information processing apparatuses 435, 436, 437 in correspondence with the order of the divided synthesized packets according to the type of the control information.

First, the conversion of PID will be described.

PID is ID of each packet, and PID 0 is reserved as PAT. The PAT has a PID of a packet called a PMT inside, and the PMT includes information indicating a PID of video and audio packets.

Accordingly, the decoder first finds the packet of PID 0 and analyzes the PAT of PID 0 to know the PID of the PMT.

However, since the broadcast or commercial video stream and the audio video stream are generated in different ways, even though the PAT with PID 0 has the same PID, the PID indicating the PMT is specified differently so that the PID and the advertisement data of the PMT of the broadcast data are different. The PID error of the PMT should be matched to a similar level so that the decoder error does not occur due to the sudden PID change in the decoder.

For example, if the PID of the PMT of the broadcast data is 2 and the PID of the advertisement data is 102, the decoder may also receive and decode the PMT of the advertisement data based on the PID of the PMT. It is expected that the PID of the PMT will be present at the level, ie the level of one digit. It is common practice to operate the decoder in this manner to maximize the processing speed of the decoder.

However, since the PID of the PMT of the advertisement data is 102, the decoder cannot find the PMT from the PID of a single digit. Therefore, the decoder decodes the PAT of the advertisement data and confirms that the PID containing the PMT is 102. The packet must be decoded, which results in a delay in processing time in the decoder that must decode a certain data size at a given time, which in turn causes a broken picture.

In order to prevent this, the present invention remaps the PID of the PMT of the advertisement data based on the control information of the broadcast data, that is, the PID of the PMT included in the PAT.

In the above example, since the PID of the PMT of the advertisement data is 102, it is re-mapped to a non-overlapping number among levels similar to the number 2 of the PID of the broadcast data.

The PID remapping is performed by the PID remapping unit 435 of FIG. 4.

In addition, when synthesizing broadcast data and advertisement data, PCR (Program Clock Reference) should be adjusted. PCR is information inserted in the middle of a transport stream and is reference clock information for reference when decoding the entire stream.

Specifically, in order for the audio stream combined with the continuous video to be synchronized and decoded and output, the standard (ISO 13818-1) requires that PCR be transmitted in the valid field of the MPEG-TS packet every 100 milliseconds.

PID with PCR for MPEG-2 programs is identified by the pcr_pid value in the associated program map table (PMT).

If no problem, the value of PCR generates system_timing_clock in the decoder. However, if a problem occurs, the decoder must separately refer to the exact time zone for synchronizing the video and audio basic systems. For example, a Presentation Time Stamp (PTS) can be used to generate the PCR data. PTSs are different from each other and cannot be referenced.

Accordingly, in the present invention, first, the PCR included in the advertisement data is adjusted based on the PCR information included in the broadcast data to fit the broadcast data. In addition, the PTS included in the broadcast data and the advertisement data is also adjusted based on the PTS of the broadcast data.

The reason why the above-described adjustment is based on the PCR and PTS of broadcast data is to prevent a sudden change in connectivity with a previously output broadcast.

As an example of an apparatus for reconditioning the PCR, a PCR regeneration unit 436 is disclosed in FIG. 4.

On the other hand, as described above, since the PID information indicating the PIDs of the video and audio streams is included in the PMT and transmitted in the control information of the transport stream, when the broadcast data and the advertisement data are synthesized, the PID and the advertisement data of the broadcast data packet are transmitted. The continuity of the PID of the packet is not guaranteed.

Accordingly, the PMT of the broadcast data and the advertisement data also contain different PID information that does not guarantee PID continuity.

That is, the PMT of the broadcast data including the PID information of the video and audio streams provided while generating the broadcast data and the PID information of the video and audio streams and the PID information of the audio and audio streams provided while generating the advertisement data. And adjust the PMT information of the advertisement data including the PID information of the video and audio streams to have continuity based on the PMT of the broadcast data.

Accordingly, the PID information of the video and audio streams of the advertisement data is adjusted based on the PIDs of the video and audio streams of the broadcast data, which are stored in the PMT.

Control information represented by ETC in FIG. 4 may be, for example, PID information, PCR information, and PTS information of a video and audio stream. In FIG. 4, the control information indicated by the ETC is illustrated by the ETC regenerator 437.

5 is a format of a transport stream.

The transport stream of FIG. 5 is officially referred to as MPEG-Transport Stream, and is collectively called TS, TP, and MPEG-TS.

The transport stream is a communication protocol for audio, video, and data transmission. It is a kind of digital container including packetized elementary streams (PES) and other control information.

The TS format of FIG. 5 is defined in MPEG-2 Part 1, System (ISO / IEC standard 13818-1), and in ITU-T Rec. Also known as H.222.0, the system aims to multiplex digital video and audio and synchronize outputs.

Since the description of each element in the format of FIG. 5 is specified in the above standard, a detailed description thereof will be omitted. However, the present invention is different from the transport stream having the format of FIG. 5 without finally decoding video and audio. Concatenating and dividing the transport streams and converting the control information of the advertisement data based on the control information included in the broadcast data so that the control information is contiguous with the transport stream of previously broadcast data. have.
