Problems solved by technology

[0004] However, such data transfer over the network causes an increase in network traffic
In addition, for a device with limited memory capacity and processing power like an embedded device, it is difficult to perform such sorting because it cannot store a large amount of data in its own device at one time

no. 1 approach

[0035] figure 1 It is a block diagram showing the configuration of main parts of the device 10 and the device 11 . The device on one side has components to communicate with other devices on the other side, has a protocol stack of Universal Plug and Play (UPnP A / V, hereinafter referred to as UPnP A / V), and sends UPnPA to devices that follow the UPnP A / V standard. / V commands for remote control, etc., receive UPnP / AV commands, and act according to the received commands.

[0036] In the same figure, the device 10 includes a communication unit 30 , a UPnP A / V command processing unit 400 , an operation unit 5 , and a display unit 6 .

[0037] The UPnP A / V command processing unit 400 converts a command input from the operation unit 5 into a UPnP A / V command defined by the UPnPA / V standard, and processes a UPnP A / V response command.

[0038] The extended command processing unit 410 and the extended command processing unit 411 process the UPnPA / V command defined by the extension. H...

no. 2 approach

[0072] In the above-mentioned first embodiment, the configuration in which the Browse command is used when acquiring the list of content information has been described. Furthermore, in this embodiment, the structure which acquires the list of content information using a Search command is demonstrated.

[0073] Since the configuration diagram in this embodiment is the same as that in the first embodiment, description thereof will be omitted. However, it is different from the first embodiment in the following points.

[0074] That is, compared with the extended command processing unit 410 and the extended command processing unit 411 processing the X_GetStartingIndex command in the first embodiment, the extended command processing unit 410 and the extended command processing unit 411 in this embodiment process the X_SearchStartingIndex command.

[0075] The Search command has the following parameters: (1-1) collection of content information list acquisition objects, (1-2) search...

no. 3 approach

[0084]In each of the above-mentioned embodiments, a configuration has been described in which, in the state where the content information list is displayed, the position information of the sorted content data is obtained in advance, and the content information is listed using the position information, thereby displaying the selected content data. Specific content data is used as a basis for sorting. Furthermore, in this embodiment, a structure will be described in which specific content data appears at a specific position when acquiring a list of content information.

[0085] Since the structural diagram of this embodiment is the same as that of the first embodiment, description thereof will be omitted. However, it differs from the first embodiment in the following points.

[0086] That is, compared with the extended command processing unit 410 and the extended command processing unit 411 in the first embodiment processing the X_GetStartingIndex command, the extended command ...

Abstract

An electronic device capable of acquiring a data list information list which a user desire more efficiently when the data information list is rearranged. The device (11) comprises a communication section (31) for transmitting / receiving UPnP A / V commands through a communication channel (2) to / from a device (10), an UPnP A / V command processing section (401) for processing an UPnP A / V command defined in conformity with the UPnP A / V standards an extension command processing section (411) for processing an extensively defined UPnP A / V command, a content information managing section (70) for managing information on the content data stored in a content storage section (71), and the content storage section (71) for storing content data.

Description

technical field [0001] The present invention relates to a system for sorting information lists stored in other devices from one device through a wired communication network or a wireless communication network according to keywords, and obtaining the sorted information list. Background technique [0002] By selecting and sorting specific data when displaying a data list in software such as personal computer information browsing and e-mail, it is possible to perform sorting centered on the selected data. [0003] This kind of sorting is based on the data stored in the device. When sorting the data stored in the device connected through the network as the object, it is necessary to store all the data in the device connected through the network in its own device at one time. Inside. [0004] However, such data transfer over the network causes an increase in network traffic. In addition, for a device with limited memory capacity and processing capability like an embedded device...
