Patent No. US11277650 (titled "Contents Receiving System And Client") was filed by Maxell Ltd on Apr 22, 2020.
’650 is related to the field of content delivery, specifically focusing on personalized subsidiary content alongside main content in systems employing both a main receiving terminal and multiple subsidiary terminals. The background involves delivering digitized video content, along with subsidiary content like data broadcasts and advertising, to receiving terminals. A challenge arises when different users within the same household have varying preferences for subsidiary content, necessitating a way to personalize this content.
The underlying idea behind ’650 is to enable the personalization of subsidiary content delivered alongside main content by using unique identifiers associated with each subsidiary receiving terminal. The main receiving terminal transmits subsidiary content tailored to the specific ID of each subsidiary terminal, ensuring that each user receives content relevant to their individual preferences. This allows for a shared viewing experience of the main content while providing personalized information and data to each user through their own device.
The claims of ’650 focus on a content reproducing system comprising a main terminal and multiple subsidiary terminals. The main terminal stores content, displays content on a first display, and controls communication with the subsidiary terminals. It also stores device-specific IDs for each subsidiary terminal, content information for identifying different content types, and association information linking specific content to specific device IDs. The subsidiary terminals each have a display and a controller that transmits their device-specific ID to the main terminal upon connection.
In practice, the system operates by the main terminal determining whether a subsidiary terminal can connect based on its device-specific ID. Using the stored association information, the main terminal then transmits the appropriate content to each connected subsidiary terminal. For example, one subsidiary terminal might receive English audio while another receives subtitle data, all while the main terminal displays the main video content. This allows family members to watch the same movie but receive personalized supplementary information.
This approach differentiates itself from prior art by addressing the need for personalized subsidiary content. Earlier systems lacked the ability to tailor subsidiary content to individual users' preferences. By using device-specific IDs and association information, ’650 enables a more engaging and relevant user experience, allowing each user to receive the information and data they are most interested in while still participating in a shared viewing experience. The system can also handle payment transactions related to the content based on the user's ID.
In the mid-2000s when ’650 was filed, at a time when systems commonly relied on broadcast or network delivery of content to receiving terminals. At that time, it was typical to display both main and subsidiary content on a single television receiver, which could lead to a cluttered display. Technologies were emerging to display subsidiary content on separate devices, but personalization of this subsidiary content was not yet widely adopted.
The examiner approved the application because the prior art did not teach or suggest storing device-specific identification information for subsidiary terminals, storing content information, and storing association information for transmitting content to specific subsidiary terminals based on the device-specific ID. The examiner stated that the prior art did not teach or suggest these limitations when taken as a whole.
This patent contains 4 claims, with claims 1 and 4 being independent. The independent claims are directed to a content reproducing system comprising a main terminal and one or more subsidiary terminals, focusing on the storage, transmission, and display of content based on device-specific identification and association information. The dependent claims further define the content reproducing system of claim 1.
