Problems solved by technology

[0022] However, in conventional display processing devices, there is a problem that the display performance of graphic images is low.
[0023] In the prior art, since the OSD plane, video plane, and still picture plane can only be processed one by one, the display performance of graphic images cannot be improved.
For example, it is difficult to overlap 2 animations to display

Embodiment approach 1

[0091] Embodiments of the cable TV system of the present invention will be described with reference to the drawings.

[0092]Fig. 3 is a block diagram showing the relationship of devices constituting the cable television system. The cable TV system has a head end 101 and three display processing devices—terminal device A 111 , terminal device B 112 , and terminal device C 113 . In this embodiment, three terminal devices are connected to one head end 101 , but any number of terminal devices can be connected to the head end 101 to implement the present invention.

[0093] The headend 101 transmits broadcast signals such as video, audio, and data to a plurality of terminal devices, and receives data transmission from the terminal devices.

[0094] The present invention mainly relates to the terminal device, so the detailed description related to the head end is omitted.

[0095] The terminal device A 111 , the terminal device B 112 , and the terminal device C 113 each receive a...

Embodiment approach 2

[0189] In Embodiment 1, the change of the vertical relationship of the regions in the OSD plane 211 is only a change within the OSD plane, and no change across planes is possible. In Embodiment 2, changes across planes are possible.

[0190] FIG. 24 is a conceptual diagram of the relationship between hardware components and software components related to the display function of the terminal device 200 according to the present embodiment. In FIG. 24 , members assigned the same reference numerals as those in FIG. 8 denote the same members as those in Embodiment 1 shown in FIG. 8 , and thus detailed description thereof will be omitted. As shown in FIG. 24, the OSD processing unit 505h, the video processing unit 505i, and the still picture processing unit 505j do not have a Z-order management unit 601, a Z-order changing unit 602, a Z-order managing unit 611, a Z-order changing unit 612, and a Z-order managing unit 611, respectively. The order management unit 621 and the Z order ...

Abstract

There is provided a display processing device having an improved display performance of graphics image. The display processing device includes: an OSD plane (211) having a first OSD area (671) and a second OSD area (672) for storing graphics image; a Z order management unit (601) containing the hierarchical relation set for the first OSD area (671) and the second OSD area (672) and reporting the hierarchical relation; a CPU (217) executing an application (506) downloaded so as to store graphics image in the first OSD area (671) and the second OSD area (672) according to the hierarchical relation reported from the Z order management unit (601); and a display (212) for superimposing the graphics images stored in the first OSD area (671) and the second OSD area (672) according to the hierarchical relation and displaying them.

Description

technical field [0001] The present invention relates to a display processing device that downloads an application program and displays an image based on the application program. Background technique [0002] Conventionally, a display processing device typified by a digital television terminal has been proposed that downloads an application program (hereinafter simply referred to as an application) and displays an image based on the application program. [0003] The technology related to the display processing device (digital TV terminal) that downloads and executes the application program is described in Non-Patent Document 1 (European digital TV standard——DVB-MHP standard (ETSI TS 101 812 DVB-MHP standard V1.0.2) ), Non-Patent Documents 2 and 3 (Standards for Home Digital AV Equipment——HAVi Standard (Home Audio Video Interoperability, Home Audio Video Interoperability)), etc., are known technologies. The DVB-MHP standard adopts the Java (registered trademark) class library...
