RSS TV

Home | Up

RSS-TV is an XML-based navigation protocol for Internet Media services based on the RSS standard.

The adoption of RSS-TV enables video device manufacturers to develop applications to navigate Internet media services. Example video devices include set top boxes, game consoles, broadband-connected digital video disc (DVD) players, digital video recorders (DVRs), personal video recorders (PVRs) and next generation mobile phones. By implementing the RSS TV protocol, these devices provide user access to a growing library of online media (video, audio and games) services.

RSS-TV is an extension of RSS and includes additional XML elements and attributes to enable Premium TV-centric features such as:

• Video On Demand (VOD) and Subscription Video On Demand (SVOD)
• Navigating media services (video, audio, games) in a hierarchical fashion
• Capturing user input (such as a user personal identification number (PIN), search query, or email) and automatic search suggestions.
• Network PVR functionality
• Secure download of HD content
• Electronic Program Guide for live streams
• Automatic language selection
• Numeric shortcuts for selecting menu items

Readers familiar with digital video broadcasting (DVB) can compare RSS-TV with the DVB Service Information standards developed in the 1990s for digital TV EPGs. The difference is that RSS-TV has been developed for two-way Internet Protocol (IP) networks rather than broadcasting networks. RSS-TV leverages the increasing availability of products that support RSS such as caching engines and RSS-enabled content management and publishing systems.

RSS-TV compliant applications can be implemented using any language and operating system including AJAX/HTML, Flash, OpenTV, or C. Similarly, service providers can use any web service technologies (Java, .NET, PHP) to build RSS-TV compliant services.

Podcasting

RSS-compliant feeds that use enclosures for video/audio (podcasting) are fully compliant with RSS-TV. RSS-TV compliant clients will display these feeds as a list of menu items and will play (or download) the media.

RSS-TV Namespace

RSS-TV uses the namespace 'tv'. The schema will be made available at http://www.rss-tv.org/rss/tv1.0.

Encoding

Similar to other XML-based standards, RSS-TV documents are assumed to be 8-Bit Unicode Transformation Format (UTF-8) encoded.
