Abstract: A BLOCK-REQUEST STREAMING SYSTEM PROVIDES FOR IMPROVEMENTS IN THE USER EXPERIENCE AND BANDWIDTH EFFICIENCY OF SUCH SYSTEMS, TYPICALLY USING AN INGESTION SYSTEM (103) THAT GENERATES DATA IN A FORM TO BE SERVED BY A CONVENTIONAL FILE SERVER (HTTP, FTP, OR THE LIKE), WHEREIN THE INGESTION SYSTEM (103) INTAKES CONTENT AND PREPARES IT AS FILES OR DATA ELEMENTS TO BE SERVED BY THE FILE SERVER. THE SYSTEM MIGHT INCLUDE CONTROLLING THE SEQUENCE, TIMING AND CONSTRUCTION OF BLOCK REQUESTS, TIME BASED INDEXING, VARIABLE BLOCK SIZING, OPTIMAL BLOCK PARTITIONING, CONTROL OF RANDOM ACCESS POINT PLACEMENT, INCLUDING ACROSS MULTIPLE PRESENTATION VERSIONS, DYNAMICALLY UPDATING PRESENTATION DATA, AND/OR EFFICIENTLY PRESENTING LIVE CONTENT AND TIME SHIFTING.

Abstract: A block-request streaming system provides for low-latency streaming of a media presentation. A plurality of media segments are generated according to an encoding protocol. Each media segment includes a random access point. A plurality of media fragments are encoded according to the same protocol. The media segments are aggregated from a plurality of media fragments.

Abstract: A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server, which might include a cache. A client device can be adapted to take advantage of the ingestion process as well as improvements that make for a better presentation independent of the ingestion process. The client devices and ingestion system can be coordinated to have a predefined mapping and template for making block requests to HTTP file names that a conventional file server can accept through the use of URL construction rules. Segment size might be specified in an approximate manner for more efficient organization.

Abstract: Un procedimiento de petición de datos de medios en un dispositivo de cliente (108) usando un mapa de segmentos escalable, que comprende: recibir el mapa de segmentos escalable en el dispositivo de cliente (108), incluyendo el mapa de segmentos escalable metadatos con uno o más rangos de bytes correspondientes a ubicaciones de capas de un segmento de medios (510), en donde el segmento de medios (510) incluye uno o más bloques y se asocia con una transmisión escalable codificada por vídeo que incluye múltiples capas que se pueden combinar para formar una o más representaciones; determinar, por el dispositivo de cliente (108), una o más capas de un bloque de segmento de medios (510) para solicitar; generar, por el dispositivo de cliente (108), una petición para las una o más capas del bloque, incluyendo la petición un rango de bytes correspondiente a una ubicación de las una o más capas, en donde el rango de bytes se determina desde los metadatos incluidos en el mapa de segmentos; transmitir, por el dispositivo de cliente (108), la petición para las una o más capas del bloque; recibir, en el dispositivo de cliente (108), las una o más capas del bloque de datos de medios; y generar, por el dispositivo de cliente (108), una representación de medios usando las una o más capas del bloque.
