Embodiment Construction

[0070] Hereinafter, embodiments according to the technology disclosed in this specification will be described in detail with reference to the accompanying drawings.

[0071] figure 1 A configuration example of a communication system based on a 2-box pull system (system use) defined by DLNA Guidelines 1.0 is shown. The DMS that provides content through the home IP network and the DMP that reproduces the content received through the home IP network are connected through the IP network laid out in the home according to predetermined connection conditions. DMS provides static content stored in its own memory. In addition, the DMS is also connected to an external network such as the Internet, and can provide live content obtained from a provider through the external network. Note that "provider" here refers to a vendor that provides services and content.

[0072] In the illustrated communication system, the CDS function formulated in UPnP is incorporated. Details thereof will b...

Abstract

Sufficient meta-information relating to live content is provided to equipment in a suitable manner. An expanded CDS for content information being delivered, the CDS being adapted to carry information about the details of the content being delivered, is defined separately from a standard CDS accessed during content browsing. In the expanded CDS for the content information being delivered, a container is provided for each client at the point of delivery, and a content node being delivered is placed under the command of the container node at each point of delivery. A rule relating to the expanded CDS for the content information being delivered is shared with the client, whereby information about the expanded CDS for the content information being delivered can be specified by the client for the content reproduced by the client.

Description

technical field [0001] The technology disclosed in this specification relates to a communication system, a communication device, and a communication method that perform a content delivery service according to the DLNA standard, and particularly, a communication system, a communication device, and a communication method that provide meta information of content through a CDS function. Background technique [0002] Recently, most AV contents have been digitized, and media for recording and reproducing digital contents such as CDs and DVDs have been widely used. In addition, distribution / delivery services of content such as images and music via the network have become popular, and content delivery is performed between remote terminals via the network without transfer of media such as CD and DVD. In addition, the Digital Living Network Alliance (DLNA) has standardized in which AV contents digitized based on Universal Plug and Play (UPnP) which allows only devices to Connect to t...
