摘要： Techniques for publishing key pictures at a server and using the key picture information for operations on a client device are described herein. In accordance with various embodiments, the server creates an intermediate unit including key picture(s) from media content. The server then generates map(s) specifying for each key picture, a type, properties, and an association to the intermediate unit. The server also packages the intermediate unit into key picture unit(s) according to the map(s). The client device obtains a manifest for the media content referencing the key picture(s) and the type of each key picture. Upon receiving a request to perform operation(s) on a respective key picture, the client device obtains a corresponding key picture unit and parses the manifest to determine a respective type. Based on the respective type matches a criterion, the client device performs the operation(s) on the key picture unit.
