摘要： Methods and systems for enabling client-controlled streaming of segmented content are described. In one example, the client-controlled streaming is on the basis of a manifest file, the manifest file including one or more segments identifiers and one or more associated segment locators, In one example, a method involves: requesting the delivery of at least one segment on the basis of a first segment identifier selected from the manifest file; on the basis of the first requested segment, selecting a second at least one segment identifier from the manifest file, the second segment identifier being associated with an expected future segment request; and pre-resolving a first segment locator associated with the selected second segment identifier for obtaining network information associated with the first segment locator.

摘要： Systems and methods for adaptive bitrate streaming of media stored in Matroska container files utilizing Hypertext Transfer Potocol (HTTP) in accordance with embodiments of the invention are disclosed. In one embodiment, a processor configured, via a client application, to request portions of files from a remote server. In addition, the client application further configures the processor to retrieve top level index data that identifies a plurality of EBML container files and describes at least a maximum bitrate of the alternative streams contained within the EBML container files, parse the top level index data to obtain information identifying the plurality of EBML container files, request a portion of at least one of the EBML container files that contains the at least one element that specifies the encoding parameters of the stream contained within the EBML container file, retrieve an index that references each element containing portions of encoded video within at least one of the EBML container files, utilize the index to request portions of a first EBML container file that includes elements that contain portions of encoded video, receive and buffer the requested elements, decode the encoded video contained within the buffered elements utilizing the encoding parameters, measure current streaming conditions, and select another of the EBML container files from which to retrieve elements containing portions of encoded video for decoding, where the selection is based upon the measured streaming conditions and the description of the bitrate of the alternative stream contained within the top level data.

摘要： An apparatus, system, method, server, and client are provided for media position control. A client sends to a player a request for setting up a streaming session, and the streaming session is set up between the player and a server. A communication channel is set up between the client and the server. An interfacing message is defined and communicated between the client and the server over the communications channel that indicates a read position in a media. A continuous stream is created in the server in accordance with the read position.

摘要： Disclosed are methods for associating size information with each chunk of a media presentation. This size information is sent (700) to an end-user device (110). There are many ways to characterize the size of a chunk beyond simply giving the number of bytes in the chunk. Some embodiments send an approximation of the size or a relative size. In some embodiments, a server (104) publishes a "reference" value for a media presentation and then, for each chunk, gives the size relative to that reference value. The device (110) decides (702) whether or not to download the chunk. The device (110) might decide that it is unlikely that the next chunk can be downloaded in time. Then, to avoid the possibility of a video freeze, the device (110) could request (704) the next chunk at a lower resolution. In some situations, the device (110) decides to request (704) a completely different chunk or to not request any chunk at all.

摘要： According to one embodiment, an electronic apparatus (10) starts, when a playback position has been changed to a first data position in the multimedia content data, which has not yet been stored in the buffer (401), a first buffering process for successively receiving data parts, which follow the first data position in the multimedia content data, from a server (21), and storing the data parts in the buffer (401). The apparatus (10) skips, when an audio data part in the multimedia content data, which is not stored in the buffer (401), has been requested, execution of a second buffering process for receiving the requested audio data part from the server (21) and storing the audio data part in the buffer (401).

摘要： A method for providing a start-over feature in a switched digital video system (100) that allows a user to watch a program from the beginning even through the user has tuned to the channel for the program after the program has begun, comprising: caching a copy of the program on a video server; providing an option to the user to watch the program after it has already begun at a rate that is faster than the real time rate of the program so that it will fit into a duration that is less than the originally scheduled duration for the program; determining the time remaining for the program; receiving a selection from the user of the option; and in response to receiving the selection by the user of the option, streaming the program to the user from its beginning at a rate that is faster than the real time rate of the program so that the viewing time of the stream is substantially the time remaining in the originally scheduled timeslot for the program.
