Sample entries and random access
In one example, a device for retrieving video data includes one or more processors configured to, in response to determining that a lowest track of a plurality of tracks, the lowest track including a base layer of the video data carrying a lowest sub-layer of the video data, is to include sample entry type values for samples indicating that convenient random access is enabled, set sample entry type values for samples of each of the other tracks of the plurality of tracks that include video data to indicate that convenient random access is enabled, and generate a file including the plurality of tracks, such that the sample entry type values for the tracks of the plurality of tracks indicate that convenient random access is enabled.

Script-based video rendering
Systems and methods render video content on different user-computing platform types. The method comprises: transmitting a script to the user-computing platform, the script comprising a non-compiled series of instructions which is configured to be interpreted by an application program operating on any one of the plurality of user-computing platform types; and using the application program to interpret the transmitted script by performing the series of instructions to thereby decode encoded video data accessible to the user-computing platform into decoded video data comprising one or more frame images without use of a previously compiled program module that is installed prior to the interpreting and without compiling the series of instructions prior to the interpreting.

Video file universal identifier for metadata resolution
Novel tools and techniques are provided for implementing media content delivery. In some embodiments, a globally unique identifier (GUID) associated with a particular media content might be embedded in headers of packets of a transport stream of the media content. When the transport stream is received by a user device, the GUID might enable retrieval of the necessary metadata (and/or updates of metadata) for enabling presentation of the media content. Alternatively or additionally, ratings or similar information can likewise be embedded in the headers of packets or I-frames of the transport stream, which enables a user (e.g., parent) to easily block or skip objectionable content from children who may be present. Alternatively or additionally, the transport stream may be combined with auxiliary data streams containing metadata and other associated auxiliary content to create a combined transport stream, to ensure no lost or corrupted media content during transmission.
