    摘要: One or more methods and systems of indexing an AVC video stream are presented. In one embodiment, the method comprises identifying one or more fields within a picture of an AVC video stream. In one embodiment, a field of the one or more fields indicates the beginning of each picture. In a second embodiment, a field of the one or more fields indicates a picture type of a picture. In a third embodiment, a field of the one or more fields indicates whether a picture is a reference or a non-reference picture. By determining that a picture is a non-reference picture, the picture may be discarded, thereby reducing the memory required to implement the indexing system while increasing the available memory size. In one embodiment, a system of indexing an AVC video stream comprises a control processor, a memory, and a set of instructions resident in the memory.

    摘要: Systems and methods for transmitting content using segment-based and non-segment-based streams are provided. In some aspects, a method includes identifying at least one segment-based stream of content. Each segment-based stream is associated with a respective first bit rate and includes one or more segments of the content. The method also includes identifying at least one non-segment-based stream of the content. Each non-segment-based stream is associated with a second bit rate and includes a continuous stream of the content. The method also includes enabling switching between use of i) the at least one segment-based stream and ii) the at least one non-segment-based stream to continuously transmit the content to one or more client devices.

    摘要: Systems and methods for prioritizing adaptive bit rate distribution of content are provided. In some aspects, a method includes identifying a plurality of content streams. Each of the plurality of content streams is associated with a variant feature of content to be delivered to the client device. Each variant feature of the content comprises at least one of a bit rate and a non-bit rate feature. The method also includes determining a priority of each of the plurality of content streams relative to one another based at least on the non-bit rate feature associated with each of the plurality of content streams. The method also includes providing an indication of the priority of each of the plurality of content streams to the client device.

    摘要: An apparatus and method for converting an IP-based multimedia channel and distributing the channel to a plurality of non-IP enabled devices based on the channel's popularity among the devices. The apparatus identifies a plurality of multimedia channels requested by a group of devices, and determines a data rate for providing each channel to the devices based on a popularity of each channel among the devices. The apparatus uses an adaptive bit rate (ABR) client to receive content segments for a respective one of the multimedia channels from an ABR server at a source data rate aligned with a determined data rate for providing the respective multimedia channel. The content segments are received at the source data rate, and converted by the apparatus to a continuous digital content stream. The apparatus then provides the continuous digital content stream to one or more of the devices at the determined data rate.
