摘要： Data objects are delivered over a packet-switched network and receivers receive encoded symbols, such as repair symbols, broadcast or multicast, with sufficient information to form requests for additional symbols as needed based on what source symbols or sub-symbols are needed or missing. The requests can be made in a unicast or request fashion. Requesting and broadcasting might be done by different entities. A broadcast server can generate and store repair symbols while a source server can store content in source form. A request can be a unicast HTTP byte-range request, such as a URL, starting position and length. Requests might be aligned with starting positions of files. A receiver can calculate starting and ending byte positions of symbols or sub-symbols in a file and get indications that conventional HTTP servers are usable for file repair. Repair servers can request broadcast of repair data when byte-range requests from multiple receivers overlap.
摘要翻译：数据对象通过分组交换网络传送，并且接收机根据需要或基于哪些源符号或子符号需要或丢失，根据需要接收具有足够信息的编码符号（如修复符号，广播或多播）以形成对附加符号的请求。请求可以以单播或请求方式进行。请求和广播可能由不同的实体完成。广播服务器可以生成和存储修复符号，而源服务器可以以源形式存储内容。请求可以是单播HTTP字节范围请求，例如URL，起始位置和长度。请求可能与文件的起始位置一致。接收器可以计算文件中符号或子符号的开始和结束字节位置，并获得常规HTTP服务器可用于文件修复的指示。当来自多个接收器的字节范围请求重叠时，修复服务器可以请求广播修复数据。

摘要： In embodiments of systems and methods for synchronous content presentation, an Edge server device may receive a decryption key for an encrypted content segment that is or will be delivered to a plurality of wireless devices over the wireless communication network, and may send the decryption key to the plurality of wireless devices after the encrypted content segment has been received by the plurality of wireless devices in a manner that enables the plurality of wireless devices to decrypt the encrypted content segment approximately simultaneously. A wireless device may receive, and optionally temporarily store, the encrypted content segment from the wireless communication network, receive the decryption key from the Edge server device after receiving the encrypted content segment, and decrypt the stored encrypted content segment using the received decryption key.

摘要： Techniques are provided for processing media content. For example, a process can include using a scene description for to obtain media information and buffer information for a media object. The media information can identify an expected format for storing the media object in one or more output buffers of a media pipeline. The buffer information can include output buffer attributes. The process can include using the media information and the buffer information to initialize the media pipeline for the media object. The process can include obtaining the media object in a delivery format and generating one or more processed media objects. Each processed media object can be converted from the delivery format to the expected format for storing the processed media object in an output buffer. The process can include outputting the processed media object(s) to the output buffer(s) using the initialized media pipeline.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, by an edge enabler client of the UE, to trigger generation of a shadow application context to support an application that is associated with an application context and that is served by an edge network device. The UE may determine, by the edge enabler client, to transfer support of the application from the application context to the shadow application context, and transfer, by the edge enabler client, support of the application from the application context to the shadow application context. In some aspects, an application context may be transferred between a UE and an edge network directly, without the shadow application context. Numerous other aspects are provided.

摘要： Various aspects include methods for facilitating digital rights management (DRM) within an electronic device. Various aspect methods may include receiving a first broadcast message, storing a DRM license object extracted from the DRM license-related message, receiving a DRM license request message generated by a content decryption module (CDM) of the electronic device, determining that the DRM license object is associated with the encrypted content received by the electronic device during the broadcast content session based on the identification information included in the DRM license request message received from the CDM of the electronic device, and sending the DRM license object to the CDM of the electronic device. The first broadcast message may be a DRM license-related message generated by a broadcast server. The DRM license request message may include identifier information associated with encrypted content received by the electronic device during a broadcast content session.

摘要： In various implementations, methods, apparatuses, and computer-readable media are described for providing an indication that a file includes corrupted video frames. For example, the file can include an indicator to indicate one or more video frames associated with a particular playing timestamp and playing duration are corrupted. The indicator can also be configured as an unified indicator associated with both corrupted video frames and missing video frames. In some implementation, the signaling of presence of corrupted video frames can come in the form of omission of those corrupted video frames from the media file. In various implementations, modifications and/or additions to one or more existing media streaming schemes can also indicate to a receiver device that a media segment contains missing (or otherwise non-decodable) frames, prior to the receiver device requesting the media segment.
