That is, the IP set-top box (STB) 120 is the EPG / ECM and EPG streams transmitted from the head-end server end 300 through the IP-switch 140 and the subscriber network 130 through the subscriber end 100 ), Extracts the corresponding channel channel video based on the customized parent organization information embedded in the IP-set top box (STB) 120 and combines the mosaic background image to display the parent EPG to the user through the TV 110. do. User requests (here, user requests can be implemented using a method of inputting user commands through a remote control, which is a commonly used method.) When editing custom lists of Mosaic EPGs, EPGs and ECMs can be organized. have.

In addition, the generation of the customized mosaic channel configuration information in the IP-set top box (STB) 120 is driven by the text-based channel editing system to customize according to the user's selection with the EPG and ECM received from the head-end server stage 300. The channel list is organized, and this information is stored in the IP set-top box (STB) 120. In addition, when upgrading the EPG by changing the channel in the head-end server stage 300, IP-set-top box (STB) 120 receives the multicast EPG and check the version, if different, the built-in custom mosaic channel information and In comparison, if there is a deletion channel, the customized mosaic channel configuration information is automatically changed.

Meanwhile, the head-end server terminal 300 receives a broadcast channel signal from a terrestrial wave or a program provider (PP) and converts it into a SDI (Serial Digital Interface) signal to a digital splitter (# 1 to #N) 370. Baseband unit 380 for transmitting, EPG generator 340 for receiving channel information from terrestrial or PP and generating channel program information (EPG), and user channel subscription information (CAS) through a Conditional Access System (CAS) system. An ECM generator 330 for generating an ECM and a digital divider for distributing the source video signal received for each channel from the baseband unit 380 into a channel video signal and a mother video signal (# 1 to #N) Compressing (encoding) the channel (SD-level resolution) video signal received from the digital splitters (# 1 to #N) 370 and the video signal for the mother-to-video (QCIF (Common Intermediate Format) or lower resolution) For channel / for hat Coder (# 1 ~ #N) (350,360) and the compressed video signal to generate a channel-specific IP stream and a single IP stream for the mother, and from the EPG generator 340 from the EPG and ECM generator 330 from the ECM And IP-packing them into IP packets and multicasting them to the IP network 200 (transport network) via the MPEG-2 TS (Transport Stream) through the switch 310.

Referring to the function of the customized video mosaic EPG service system according to the present invention having the configuration as described above in more detail as follows.

The digital divider (# 1 to #N) 370 generates the source video signal received for each channel from the baseband unit 380 into two identical video signals, thereby generating the channel encoder (# 1 to #N) 360 and the lower blade. To the encoder 350 (# 1 to #N) 350 for distribution (distribution).

The channel encoder (# 1 to #N) 360 encodes the video channel stream distributed from the digital splitter (# 1 to #N) 370 in real time to an SD level of resolution and compression rate, and uses an Asynchronous Serial Interface. ) And outputs the signal to the IP-Mux 320.

The encoder for the mosaic (# 1 to #N) 350 converts the video channel stream distributed from the digital splitter (# 1 to #N) 370 to a customized mosaic video at the performance level of the IP-set top box (STB) 120. Real-time encoding at low resolution (lower than QCIF) and low compression rate (below 300k) for reproduction, output as an ASI signal, and forwarded to IP-Mux 320.

The IP-mux 320 outputs the video received from the channel encoders (# 1 to #N) 360 as IP streams for each channel, and from the encoder for the mosaic (# 1 to #N) 350. A plurality of received videos are bundled into one channel and output as a single IP stream so that the IP streams are multicasted to the IP network 200 through the switch 310. In addition, the EPG receives the ECM from the EPG generator 340 from the EPG generator 340 and outputs the IP stream along with the video signal to multicast the data. At this time, the configuration of the IP network 200 is composed of a backbone network and a subscriber network, the backbone network is configured by Gigabit Ethernet, the subscriber network is configured by VDSL.

Subsequently, information about a channel subscribed to by the user is generated. That is, the ECM is generated from the Conditional Access System (CAS) (202).

Next, the baseband unit 380 receives live A / V from a terrestrial service provider or a PP service provider through an exclusive network (IP network), and generates a plurality of source video channels for each channel through the digital distributor 370 ( 203).

One channel video generated in this way generates a video stream for a broadcast source for the channel of SD resolution (720x480) and compression rate (1.5Mbps ~ 2.5Mbps) through the encoder for the real-time channel (204), or One channel video generates a channel video stream for a low EPG source of low resolution (200x130) and compression rate (300 Kbps) through the real-time encoder 350 for the mother blade (205).

Finally, the IP-Mux 320 receives the generated channel program information (EPG), user channel subscription information (ECM), video stream for channel, and stream for mosaic EPG, and multiplexes the IP network 200. Multicast to 206. At this time, the video stream for the channel is multiplexed into one stream for each channel by placing a plurality of IP-muxes, and since the mother video stream is a high compression, N channels are divided into individual videos to be divided into a single video stream. Send by multiplexing.

3 is a diagram illustrating an embodiment of a subscriber end of a customized video mosaic EPG service system according to the present invention, and shows a detailed configuration of an IP set-top box (STB) 120.

As shown in FIG. 3, the IP set-top box (STB) 120 is multiplexed with the channel program information (EPG) and the user channel subscription through the IP-mux 320 of the head-end server terminal 300.

Through the decoding unit (# 1 ~ #N) 124 and the buffering unit 123 for decoding the video by dividing and decoding for each channel by using EPG channel identification unit 125 for identifying a video of a corresponding channel according to a broadcast program name by PID (Program IDentification) value using a stored EPG, and identifying a subscription channel of a user by ECM, EPG and ECM, And a module EPG browsing unit 126 for displaying the customized video mosaic channels on the user screen by comparing the decoded video within each wing by mapping PID values.

The customized video mosaic EPG display screen 127 according to an embodiment of the present invention is displayed by way of example in a 3X3 arrangement and displays a channel number and a channel name for each channel. When the channel is selected in the customized video mosaic EPG, the actual size broadcast video is displayed through the channel video broadcast screen 128.

The operation process of the subscriber station (IP-STB) in the customized video mosaic EPG service system according to the present invention having the above configuration will be described in detail as follows.

First, when a user requests a parent EPG, the subscriber station's IP-set top box (STB) 120 performs IGMP (multiple cast) EPG video streams that are multicasted from the headend server 300 through the IP-tuner 121. Internet Group Management Protocol) joins and receives IP packets of A / V video, EPG and ECM, and forwards them to the De-Mux 122. The de-mux 122 separates (demultiplexes) the stream into individual signals for decoding processing the received multiplexed IP stream, sequentially sorts the received packets through the buffering process, and then performs an IP- Store on set-top box (STB) memory. A single stored video stream is divided and decoded by channels using a plurality of software decoders installed in an IP set-top box (STB) to decode the video. At this time, since the videos in the mosaic EPG are high compression, the IP set-top box (STB) 120 processes through various decoders. The received EPG channel information processing identifies the video of the corresponding channel by the broadcast program name by the PID value, and identifies the subscription channel of the user by the ECM.

The mosaic EPG browsing unit 126 compares the PID program with the channel program, the subscription channel information, and the video in each of the decoded PID values, and compares each other to the customized video mosaic channels composed of desired channels on the screen by using a customized mosaic EPG browser. The customized video is displayed through the mosaic EPG display screen 127.

FIG. 4 is a flowchart illustrating a process of configuring a customized video poor channel configuration in the subscriber of FIG. 3.

As shown in FIG. 4, when a user requests editing of a mosaic channel to a desired channel among the subscribed channels, the mosaic editing system mounted in the IP set-top box (STB) 120 is driven to generate a customized mosaic EPG environment ( Channel) setup screen (401).

At this time, the IP set-top box (STB) 120 receives the EPG and ECM from the head-end server (300) (402, 403), using the mutual PID value of the two information on the screen as a program name on the subscription channel list Display (404).

Subsequently, upon receiving a desired channel selection command from the user via the remote controller (405), the IP-set top box (STB) 120 generates the customized middle channel information including the PID value (406), and generates the organized list information. Editing to a customized video mosaic channel is performed by storing the file in the form of a file in the memory in the IP-set top box (STB) (407).

FIG. 5 is a detailed flowchart illustrating a process of generating and displaying a customized video mosaic EPG to conform to the customized video mosaic channel programming process of FIG. 4. It shows the operation process.

As shown in FIG. 5, when a user selects a custom EPG through a remote controller (501), a file stored in the custom channel list information file 407 of FIG. 4 is read to reproduce a custom channel list (502). The number N of custom channels is calculated (503). If the number of custom channels is greater than or equal to 0, the P-PIDs of the custom programming channels are extracted in the stored order (507).

At the same time, a single mother A / V stream is received (504), the mother single stream for each channel is divided by channel (505) by the PID value classification for each channel in the stream, and the M-PID value of the first mother channel is extracted. (508).

Subsequently, when the extracted custom channel P-PID value and the mother channel M-PID value are matched (509) and matched, the corresponding channel for the divided mother blade is decoded and buffered through a software decoder (510). Subtracting 1 from the value of the number N 503 (511), the process proceeds to " 506 ".

Repeatedly, repeating steps "507" to "511" until the N value of the number of custom channels is less than 0, and A of split channels in a single stream for a single match that matches for all channels in the user-organized channel list. Perform decoding on / V.

When the decoding of the channels in the custom list is completed, the channel number / program name and the divided parent channels are mapped by PID values through the custom module list information to generate program data and A / V of the custom module EPG. 512).

Subsequently, in order to display the generated customized EPG on the TV screen, the image of the wallpaper prestores the background image 513 for one channel size in the mosaic in the IP set-top box (STB) 120, The same image is displayed on the screen by the maximum number of channels to be configured in one screen of the mosaic. On the mosaic image, the program data generated in the process of "512" and the mosaic A / V video are sequentially displayed on the TV and provided to the user (514). If there are fewer custom channels as many as the number of channels on one screen, if there is a blank channel, it is filled with a separate background image.

On the other hand, when the user selects a channel through the remote control on the customized video mosaic EPG (515), the IP set-top box (STB) (120) IGMP A / V for the channel being multicast in the head-end server stage 300 Internet Group Management Protocol (Join) joins to receive the stream (516), and the channel broadcast video A / V (Fig. 3, 128) of the actual size is displayed on the TV screen through the decoding process (517).

FIG. 6 is a detailed flowchart illustrating a mapping process between the customized channel programming information and the received mother-video in FIG. 5, and a mapping process 509 between the customized channel programming information and the received mother-video. It is shown in more detail.

As shown in FIG. 6, "400" represents a data structure of a custom channel created by a user using a system configured in the IP-Stop Box (STB) 120, and "500" represents a headend server end ( The data structure of the parent video stream divided in 300 is shown.

In other words, by comparing the PID value of the user-organized custom channel list and the PID of the video stream for the parent, only the matching video is extracted for the match, to generate the customized mosaic EPG information, and the background image 600 is set as the background. Overwrite and display the custom mosaic EPG information above. Here, "600" is made of single channel mosaic background images (FIGS. 5 and 513) as many as the number of custom channels.

As described above, the present invention provides a single resolution by lowering the resolution and compression ratio of a plurality of channels through EPG / ECM and IP-Mux in the headend server for the configuration of a personalized video mosaic channel using an IP network. Create and send a video mosaic IP stream. Then, EPG and ECM are received from the subscriber-side IP-set top box (STB) to allow the user to organize a customized channel list using the custom channel custom editing function. In addition, a single parent video stream is received and divided by channels, and decoded by a plurality of software decoders for channels included in a personalized list, and a custom multimedia video is generated together with a program ID for each channel. Then, the combination of the mosaic image mounted in the IP-set top box (STB) and the generated customized video is provided to the user a customized video mosaic EPG service on the TV screen.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

As described above, the present invention enables a user to configure and watch a video parent EPG channel configuration according to an individual's preference (given ID for each family member) to a user using an IP network, and has an advantage of easily excluding adult material. That is, the custom EPG provided by the existing text list (TextList) -EPG and the box list (BoxList) -EPG can be provided on the parent EPG.

In addition, the present invention encodes and processes a multi-channel video EPG into one video format by lowering the resolution and compression rate at the headend server, so that only one stream of bandwidth is required. Therefore, in order to map a video and a program in the mosaic EPG, the existing fixed mosaic EPG requires a metadata generator at the head-end server side, but the present invention does not need to generate the EPG and ECM at the STB stage. . In addition, by installing a plurality of software decoders in the IP set-top box (STB), it is possible to reduce the construction cost of the IP-set top box (STB) than when installing a hardware decoder.
