Embodiment Construction

[0018] Electronic devices for decoding pictures are described. An electronic device includes a processor and instructions stored in memory in electronic communication with the processor. The instructions are capable of encoding stepwise temporal sublayer access sample packets. The instructions are also capable of transmitting and / or storing STSA sample packets.

[0019] Transmitting the STSA sample packet may include storing the STSA sample packet in a recordable storage medium. A recordable storage medium may be a file. Encoding the STSA sample grouping may include encoding the STSA sample grouping based on the ISO base media file format. The ISO base media file format can be extended to support High Efficiency Video Coding (HEVC) video streams. Sending the STSA sample packets may include sending the STSA sample packets in an ISO base media file format.

[0020] A STSA sample grouping may indicate a STSA sample. The STSA sample grouping may indicate a next time layer sw...

Description

technical field [0001] The present disclosure generally relates to electronic devices. More specifically, the present disclosure relates to methods of signaling a step-wise temporal sublayer to access samples. Background technique [0002] To meet consumer demands and to increase portability and convenience, electronic devices have become smaller and more powerful. Consumers have come to rely on electronic devices and come to expect more and more functionality. Some examples of electronic devices include desktop computers, laptop computers, cellular phones, smart phones, media players, integrated circuits, and the like. [0003] Some electronic devices are used to process and display digital media. For example, portable electronic devices now allow consumers to consume digital media in virtually any location they may be. Additionally, some electronic devices may provide for downloading or streaming of digital media content for consumer use and enjoyment. [0004] The gr...
