METHODS AND APPARATUS FOR DELIVERING CONTENT AND/OR PLAYING BACK CONTENT
Content delivery and playback methods and apparatus are described. The methods and apparatus are well suited for delivery and playback of content corresponding to a 360 degree environment and can be used to support streaming and/or real time delivery of 3D content corresponding to an event, e.g., while the event is ongoing or after the event is over. Portions of the environment are captured by cameras located at different positions. The content captured from different locations is encoded and made available for delivery. A playback device selects the content to be received based in a user's head position.

Forward error correction using source blocks with symbols from at least two datastreams with synchronized start symbol identifiers among the datastreams
A forward error correction (FEC) data generator has an input for at least two datastreams for which FEC data shall be generated in a joint manner, each datastream having a plurality of symbols. A FEC data symbol is based on a FEC source block possibly having a subset of symbols of the at least two data streams. The FEC data generator further has a signaling information generator configured to generate signaling information for the FEC data symbol regarding which symbols within the at least two datastreams belong to the corresponding source block by determining pointers to start symbols within a first and a second datastream, respectively, of the at least two datastreams and a number of symbols within the first datastream and second datastreams, respectively, that belong to the corresponding source block.
