  • Patent number: 11070832
    Abstract: Innovations in syntax and semantics of coded picture buffer removal delay (“CPBRD”) values potentially simplify splicing operations. For example, a video encoder sets a CPBRD value for a current picture that indicates an increment value relative to a nominal coded picture buffer removal time of a preceding picture in decoding order, regardless of whether the preceding picture has a buffering period SEI message. The encoder can signal the CPBRD value according to a single-value approach in which a flag indicates how to interpret the CPBRD value, according to a two-value approach in which another CPBRD value (having a different interpretation) is also signaled, or according to a two-value approach that uses a flag and a delta value. A corresponding video decoder receives and parses the CPBRD value for the current picture. A splicing tool can perform simple concatenation operations to splice bitstreams using the CPBRD value for the current picture.

  • Patent number: 10992940
    Abstract: When a temporally compressed video stream is decoded and subsequently re-encoded, quality is typically lost. The quality loss may be mitigated using information about how the source video stream was encoded during the re-encoding process. According to some aspects of the disclosure, this mitigation of quality loss can be facilitated by decoders that output such information and encoders that receive such information. These decoders and encoders may be separate devices. The functionality of these decoders and encoders may also be combined in a single device, such as a transcoding device. An example of the information that may be used during re-encoding is whether each portion of the original stream was intra-coded or non-intra-coded.

  • Patent number: 10944994
    Abstract: In one aspect, a compressed video bit stream is received and divided into packets that comprise either video data or supplemental information. Each packet is marked with a first subset identifier associated with a corresponding bit stream subset. A first sequence parameter set (SPS) is marked with the same first subset identifier as its associated bit stream subset. The first SPS comprises a second subset identifier indicating a decoding dependency of the bit stream subset associated with the first subset identifier on a bit stream subset associated with the second subset identifier. In another aspect, the packets from the bit stream are received and the first SPS is extracted. The first and second subset identifiers are used as relevant subset identifiers, and for each received packet, the first subset identifier is inspected and the packet is extracted when the first subset identifier matches one of the relevant subset identifiers.

  • Patent number: 10924819
    Abstract: Systems and methods are provided herein for automatically generating universal metadata for non-linear content when the non-linear content is determined to be viral. To this end, the systems and methods determine a first rate at which first users are consuming non-linear content from a first source. In response to determining that the first rate exceeds the threshold, the systems and methods determine a second source that from which second users are consuming the non-linear content, and a second rate at which the second users are consuming the non-linear content from the second source. In response to determining that the second rate exceeds the threshold, the systems and methods generate universal metadata for the non-linear content by automatically populating metadata fields of by scraping metadata fitting predefined criteria corresponding to the metadata fields from the first source and from the second source, and store the populated metadata fields to a database.

  • Patent number: 10893308
    Abstract: Delivering a transport stream using a hybrid statistical multiplexer. Over a plurality of multiplexing cycles, a plurality of single program transport streams (SPTSs) are multiplexed onto a multiple program transport stream (MPTS). In each multiplexing cycle, it is determined whether any portion of the packets carried by the plurality of SPTSs may be delayed such that the delayed portion is multiplexed onto the MPTS in a future multiplexing cycle. For each multiplexing cycle, delay information that identifies how many packets were delayed is determined. The size of the bit rate pool for a subsequent allocation cycle is adjusted based on the delay information for a prior multiplexing cycle. Thereafter, the MPTS is delivered to one or more recipients.
