The field of the invention relates generally to computer systems and more particularly relates to a method and system for delivering personal media over cable television.
For many years, people have collected photographs and placed them in physical albums in order to preserve and share them with other people. In recent years, with the advent of digital photography, photographs are taken and stored on personal computers and other storage devices. Digital photographs can be burned onto DVDs and CD-ROMs and shared with others.
Many digital cameras allow users to connect the camera to a television to display the digital photographs stored in the camera. Some services, such as those offered by KODAK, allow people to receive CD-ROMs with digital images stored on them, whether taken with a digital camera or a film based camera. In addition, some DVD players could read DVDs and CD-ROMs such that digital photo albums can be watched on a television.
Even more recently, technology has been developed that allows digital photographs to be uploaded to servers on the Internet and shared with other people. Websites such as OFOTO, FLICKR, SHARPCAST, and SNAPFISH have provided various ways to organize and collect digital photographs.
Digital photography has also become more and more ubiquitous in that mobile phones and other handheld devices are being sold with integrated digital cameras. Accordingly, more and more photographic content is available in digital form for which new distribution mechanisms need be developed.
A method and system for delivering personal media over cable television are disclosed. According to one embodiment, a computer implemented method comprises storing digital content, the digital content including digital photographs, digital video, and music. The digital content is queued for review. A photo show is generated from the digital content. The photo show is transmitted to a cable system for transmission on a video on demand system.

Clients 170 are computers through which users upload digital content, including photographs and videos to web server 110. Web server 110 provides an interface for users to provide content and information to be saved in content database 111. The interface may be accessed via a website, or through an application running on a client 170. One or more of clients 170 may allow network access via a web browser such as MICROSOFT'S INTERNET EXPLORER, NETSCAPE BROWSER, MOZILLA, FIREFOX, or the SAFARI browsers that support HTML and JavaScript. Additionally, clients 170 may be mobile devices, such as videophones, laptops, smart phones, mobile phones, PDAs, game devices such as the PSP manufactured by Sony Electronics, multimedia devices such as iPods and iPhones manufactured by Apple Computers of Cupertino, Calif., or similar devices. Clients 170 may also fixed devices such as set top boxes, desktop computers, media recorders such as those manufactured by TiVo, Inc. of Alviso, Calif., game devices such as the XBox manufactured by Microsoft, Corp. of Redmond, Wash. or similar devices.
Web server 110 uses any one of a number of protocols and/or applications including HyperText Transfer Protocol (HTTP), File Transfer Protocol (FTP), Internet Relay Chat (IRC), etc., via a TCP/IP connection (not shown in this view) or other similar connection protocols. The operating system may be Windows®, LINUX, SUN Solaris®, Mac OS, Tiger, or other similar operating system. It uses processing logic, tools and databases and is built using a combination of technologies such as those from Apache Software (www.apache.org) such as Tomcat servers; Java based technologies such as J2EE, EJB, JBOSS, JDBC; and/or databases such as MySQL with content database 111.
Content database 111 stores images such as digital photographs in JPEG format, although other formats are also supported. Metadata files are also stored and maintained in content database 111 in the form of XML files. Video is stored in content database 111 in FLASH VIDEO format, although MPEG is also supported. Music and clipart is stored in FLASH VIDEO format, although other formats are also supported. The contents of content database 111 are used to generate a photo show that is ultimately viewable through cable network 150 via a set top box 160.
Back end server 112 interfaces with web server 110 and content database 111 to process the digital content and information on content database 111 so that it can be provided to cable network 150. Cable network 150 includes a cable television headend that is a master facility for receiving television signals for processing and distribution over cable network 150. The cable TV headend will normally have several large FSS-type television receive-only satellite television dishes for reception of cable/satellite TV networks such as ESPN, CNN, or HBO; a dedicated, non-movable dish is required for each satellite that the cable TV utility wishes to receive cable channels from for distribution over its system. For reception of signals from several adjacent satellites, a larger non-parabolic multi-satellite dish (such as the Torus or Simulsat) that can see up to 3 or more satellites is often used. Many digital cable systems use services like HITS (“Headend In The Sky”, a unit of Comcast), which carry hundreds of channels on just a few satellites; this is commonly used by small systems to expand service without adding expensive new dishes or other equipment.
Cable network 150 also includes a video on demand system that allows users to select and watch video content over a network as part of an interactive television system. Video on demand systems either stream content, allowing viewing in real time, or download it in which the program is brought in its entirety to a set-top box 160 before viewing starts. Often, video on demand encompasses a broader spectrum of delivery devices, referring not only to set-top-boxes 160 but also computers 170, mobile phones and indeed any system that can receive on-demand audio-visual content over a network such as cable network 150.
Cable network 150 communicates with set top boxes 160 to deliver photo shows based on the content stored in content database 111. Set-top box 160 is a device that connects to a television and cable network 150, and turns the signals provided by cable network 150 into content then displayed on the screen.
System 100 may also include other supporting computing software and hardware, for example, additional website servers, databases, computers, and user interface servers.
A data storage device 227 such as a magnetic disk or optical disc and its corresponding drive may also be coupled to computer system 200 for storing information and instructions. Architecture 200 can also be coupled to a second I/O bus 250 via an I/O interface 230. A plurality of I/O devices may be coupled to I/O bus 250, including a display device 243, an input device (e.g., an alphanumeric input device 242 and/or a cursor control device 241). For example, web pages rendered by MMSW server 130 and related information may be presented to the user on the display device 243.
The communication device 240 allows for access to other computers (servers or clients) via a network. The communication device 240 may comprise a modem, a network interface card, a wireless network interface or other well known interface device, such as those used for coupling to Ethernet, token ring, or other types of networks.
Renderers 430 are transcoding appliances that include a playback engine. They request instructions (e.g. a metafile) for generating photo shows and execute the instructions to create the photo shows by converting images into a video file (e.g., animation). More particularly, each renderer 430 subscribes to a list of RSS feeds on a particular category of photo shows that it is responsible for processing. The RSS feed is provided by the workflow manager 420 and contains references to the source media and playback instructions (in the form of an XML file) contained in the content database 410. Playback instructions include a manifest of content, music, transitions, special effects, etc. The renderer 430 processes the playback instructions to produce a cable-compatible media file including video and audio. When a renderer 430 finishes processing the playback instructions, it notifies the workflow manager 420, that the photo show is complete. According to one embodiment, generation module 422 transmits to catchers 440, 441 via FTP to a video-on-demand system of cable system 150.
Catchers 440, 441 may be subgrouped to service a particular geographic area or particular cable network 150. For example, catcher 430 may service a cable network located in Hawaii, whereas catcher 431 may service a cable network located in Staten Island. Catchers 440, 441 may be instantiated within cable system 150 as part of a video on demand system.
Workflow manager 420 and video on demand (VOD) XML generation module 421 may be instantiated on back end server 112, according to one embodiment. VOD XML generation module 421 produces a unique VOD XML file for each photo show. The VOD XML file contains VOD metadata providing a title, menu, short and long descriptions, the length of the show in minutes, a rating, a license window (including a start and end date), routing instructions and a location for playing (e.g., Hawaii cable system, Staten Island cable system). According to one embodiment, the VOD XML file is related to an ADI file as defined by Cable Labs.
Workflow manager 420 also provides management functionalities to ensure that operational constraints are followed. The operational constraints are often imposed by the cable network 150. For example, cable network 150 may specify a maximum amount of space for photo shows based on time, data size and/or the number of time slots for playback on the VOD system. In addition, cable network 150 may impose a time window in which all photo shows may be transmitted to the catchers 440, 441 (e.g., 1 a.m. to 5 a.m.). Another constraint may be the times at which the particular photo show may be broadcast on-air (e.g., the number of days the photo show is available on the VOD system).
Once a photo show has been transmitted to catchers 440, 441, the photo show may have one of three states: queued, playing, or complete. As photo shows are continuously being produced and submitted to catchers 440, 441, a process for queuing the flow of photo shows exists. Multiple categories of photo shows are maintained. Each category may have a number of simultaneous photo shows that may be available. Photo shows for each category are queued and staged pending broadcast. A first in first out process may be used where each photo show is guaranteed a minimum amount of time to be available on cable system 150. A gating module controls the transfer of the queued photo shows to the playing state. When the license period of the photo show ends, the cable system 150 automatically terminates the photo show and deletes the content.
Workflow manager 420 also includes a mechanism to extend the license period of a particular photo show, by modifying the XML file accompanying the MPEG file. According to one embodiment, a duplicate photo show is generated with a new XML file that extends the license period.
The author of the photo show is automatically contacted and notified of the date and time when the photo show will be available on the cable system 150.
According to one embodiment, workflow manager 420 includes a roll-up mechanism that aggregates all photo shows in a particular category. In addition, interstitials are inserted between each photo show, where the interstitials may be advertisements or other video content. The roll-up mechanism renders a single photo show and a corresponding XML file with license information.
A method and system for delivering personal media over cable television have been described. It is understood that the embodiments described herein are for the purpose of elucidation and should not be considered limiting the subject matter of the present patent. Various modifications, uses, substitutions, combinations, improvements, methods of productions without departing from the scope or spirit of the present invention would be evident to a person skilled in the art.
