Abstract: A device for processing media content obtains data from a box within a file conforming to a file format for a video codec, the box comprising a syntax structure that includes the data, the file being associated with the media content and the media content being coded according to the video codec; and determines, based on the data obtained from the box, whether to accept or reject the media content associated with the file. A device for generating media content generates data in a box within a file conforming to a file format, the box comprising a syntax structure that includes the data, the file being associated with the media content, wherein the data is for use in determining whether a client is to accept or reject the media content associated with the file; and outputs the file.

Abstract: A proxy unit is configured to obtain mapping information that maps an identifier for media data to a resource location based on a service for retrieving the media data, wherein the service defines at least one of a plurality of types of transports for transporting the media data, receive a request for the media data from an application service client, determine whether the service is available, and, when the service is available, cause the application service client to receive the media data from a unit that receives the media data using the service from the resource location, based on the mapping information. In this manner, the application service client may receive media data from the unit (e.g., a middleware unit), which then receives the media data using a service that defines transport according to, e.g., broadcast or multicast transport, or another fashion (e.g., unicast) if the defined transport is unavailable.

Abstract: Content (e.g., multimedia streams, audio-video streams, video files, text, etc.) may be delivered to receiver devices over a broadcast channel and/or via a broadcast network via components (e.g., servers, receiver device, software applications, modules, processes, etc.) configured to communicate the content in a manner that reduces the amount of information communicated over the broadcast network, reduces the amount network bandwidth consumed by the communication, meets precise timing requirements for the individual objects that are communicated, and enables each receiver device to receive, decode, and render the content without consuming an excess amount of that receiver device's battery or processing resources.

Abstract: A device for encoding and sending media data includes a scheduler unit that schedules transmission of media data, a media encoder, and a transmitter that transmits according to a schedule formed by the scheduler unit. The scheduler unit sends a first set of data to the media encoder representing a number of media segments of the media data to be broadcast and a time at which the media data must be available for delivery at the transmitter of the media broadcast device. The media encoder sends a second set of data representing a first number of estimated encoding bytes for the media data to the media encoder. The scheduler unit sends, to the transmitter, the number of media segments including respective portions of the encoded media data at or before the time at which the media data must be available for delivery at the transmitter.
