The present invention relates to an apparatus for editing a multi-channel video display of a digital broadcast receiver. In particular, the digital broadcast receiver provides a multi-channel video including a multi-channel video including a respective broadcast channel of a plurality of local service systems from a multi-service system. Includes multiple channels of digital broadcast receivers to receive video and display them as mosaic EPG (Electronic Program Guide) on the screen, and to display video corresponding to its own broadcasting channel of the local service system where it is installed at a specific position on the same screen A video display editing apparatus.

The digital broadcasting receiver can edit, cut, scale, and transition each rectangular portion of a specific video composed of a plurality of squares. That is, the digital broadcast receiver receives the mosaic video provided from the digital broadcast station. Thereafter, the digital broadcast receiver selectively cuts and repositions a plurality of video regions arranged in the received mosaic video based on the user's key manipulation so that the user can view the transferred video. The mosaic video is produced by arranging a plurality of videos respectively corresponding to a plurality of broadcast channels on one screen. It is mainly manufactured in the form of the digital broadcast receiver set top box.

For example, the digital broadcast receiver receives a mosaic video as shown in FIG. 1A provided from a digital broadcast station. Thereafter, the digital broadcast receiver displays a plurality of broadcast channels according to a subject as shown in FIG. 1B according to a user's key manipulation so as to easily select a desired broadcast channel. At this time, KBS1 is a full still image, KBS1, KBS2, SBS of each small area is implemented as a video.

As another example, the broadcasting station may produce and broadcast a source video as shown in FIG. 2A. Accordingly, the digital broadcast receiver may configure the mosaic screen as shown in FIG. 2B or 2C by receiving the source video as shown in FIG. 2A. At this time, each square such as 1, 2, 3, ..., 16 is the current real-time video of each broadcasting channel, such as KBS, SBS.

Meanwhile, each broadcasting channel is collected from a multiple service system operated by a digital media center (DMC) or a multiple service operator (MSO) and transmitted to each regional service system operated by each regional service provider. do. Each local service system adds its own broadcast channel of its local service system, changes the broadcast channel number of the broadcast channel, and transmits each received broadcast channel to a specific digital broadcast receiver, and corresponds to the local advertisement time zone for the specific broadcast channel. You can insert local ads.

In implementing such a service, a local service provider operating a local service system is unable to perform expensive editing work on a broadcast channel transmitted from a multi-service system or a digital media center due to lack of manpower or funds. have. As a result, the mosaic EPG (Electronic Program Guide), which is commonly used, is missing its own broadcasting channel of the local service system. In other words, local service providers who operate local service systems hope to insert their own broadcasting channels, which are important for advertisements, in mosaic EPGs with high exposure. However, in order to insert its own broadcast channel into the mosaic EPG, expensive equipment for encoding and transmitting real-time own broadcast channel video in some areas of the mosaic EPG video is required.
