Embodiment approach 1

[0081]

[0082] figure 1 It is a network system diagram including video information devices in Embodiment 1 of the present invention. in addition, figure 1 Various videos such as digital television (digital TV), DVD / HDD video recorder, surveillance video recorder, FA (Factory Automation) equipment in the factory, mobile phone, PDA (Personal Digital Assistant, personal digital assistant) etc. The information devices are respectively connected to the Internet via the module units.

[0083] The network 1 is a network represented by a small-scale LAN, a large-scale Internet, and the like. Generally, unillustrated client computers (client computers) are connected to these networks, and servers (servers) that perform service provision and data transfer to each client computer are connected.

[0084] Also, a computer (here, a personal computer is referred to as a PC) PC2 is a personal computer connected to the network 1, and is used for various services or uses such as sending a...

Embodiment approach 2

[0253]

[0254] Figure 28 It shows a system configuration example in the case where the ubiquitous video module 12 is connected to the Ethernet interface of the video information device 40 .

[0255] The ubiquitous video module unit 4 including the ubiquitous video module 12 has an Ethernet interface 32 f , and the Ethernet interface 32 f is connected to the Ethernet interface 31 e of the video information device 40 .

[0256] Through the connection of the ubiquitous video module unit 4, the video information device 40 communicates / controls with other devices such as network cameras 34d, 34e, and 34f on the LAN 33 via a network such as LAN.

[0257] Here, although the video information device 40 is equipped with a protocol used for communication and control with NAS, it is not equipped with a protocol for communication and control with a network camera outside the device. In such a case, by connecting the ubiquitous video module unit 12, the video information device 40 can...

Embodiment approach 3

[0290]

[0291] FIG. 38 is a diagram showing a system configuration example when the ubiquitous video module unit 4 is connected to the video information device 40 .

[0292] The video information device 40 shown in FIG. 38 is configured to have the S-I / F 31 instead of the drive 55 and the host interface 56 shown in FIG. 7 .

[0293] Furthermore, the ubiquitous video module unit 4 is composed of the ubiquitous video module 12 and the U-I / F 32 . By connecting these respective interfaces S-I / F 31 and U-I / F 32, the video information device 40 having the function of the ubiquitous video module 12 can be realized without developing a new system LSI.

[0294] The ubiquitous video module unit 4 downloads video / audio data and the like from other video information devices on the Internet after being connected to the Internet environment via the communication engine 24 .

[0295] The MPEG4 engine 23 and the graphics engine 21 included in the ubiquitous video module 12 perform decodin...

Abstract

Without performing new development of an LSI itself in a video information device, it is possible to add a new function by connecting the video information device to a ubiquitous module unit which has components such as a hardware engine, a CPU, a general-purpose bus for providing an extended function such as graphics, a new image codec, a network function, and the like that the video information device itself does not have, and on which ubiquitous module unit an OS for operating the components is mounted.

Description

technical field [0001] The present invention relates to a video information device, in particular to a video information device that can be universally connected to a network environment by having a ubiquitous video module or a ubiquitous video module unit composed of it, and a module used in the device unit. Background technique [0002] Existing AV (Audio Visual, Audio Visual) digital network equipment has an interface for network connection and a function for connecting to the network in one device (for example, refer to Patent Document 1). [0003] In addition, there is also an example in which network-related functions are realized by system LSI (Large Scale Integration, large scale integration) (for example, refer to Patent Document 2). [0004] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2002-16619 (pages 5-6, FIG. 1 ) [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2002-230429 (pages 10-13, FIG. 2 ) [0006] Wit...
