10735789 · 2020-08-04 · ·

A transmitting apparatus, a receiving apparatus, and a data processing method that enable efficient transmission of periodically transmitting information. The transmitting apparatus arranges, in a physical layer frame including a preamble and a data portion, periodically transmitting transmission information in an area that is extractable temporally before other information arranged in the data portion, and transmits the physical layer frame as a digital broadcast signal. The apparatuses and method are applicable to, for example, digital broadcasting using an IP transmission method.

DYNAMIC ADVERTISEMENT STREAM REPLACEMENT

Mechanisms are provided for replacing default advertisement streams in a media stream with replacement advertisement streams. User profile information is obtained for a particular user and/or device. A default advertisement stream is identified and replaced with advertisement streams selected using the user profile information. Timestamp information and sequence number information is maintained to allow uninterrupted delivery of the modified media stream while customizing media streams for particular users.

Apparatus for transmitting broadcast signal, apparatus for receiving broadcast signal, method for transmitting broadcast signal and method for receiving broadcast signal

A method for processing a broadcast signal, includes generating a first group of one or more link layer packets carrying broadcast data, first level signaling information, and second level signaling information, the first level signaling information including information for one or more broadcast services and one or more components belonging to each service, the second level signaling information including information for listing the one or more broadcast services, generating a second group of one or more link layer packets carrying third level signaling information that includes physical layer pipe (PLP) identifying information for identifying a PLP to which the third level signaling information is applied, a header of each link layer packet of the second group including header type information indicating that the link layer packet carries the third level signaling information so that a receiver obtains the third level signaling information before obtaining the first level signaling information and the second level signaling information.

CONVERGENCE SUBLAYER FOR USE IN A WIRELESS BROADCASTING SYSTEM

A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.

METHOD FOR TRANSMITTING SERVICES INFORMATION IN DIFFERENT TYPES OF BROADCASTING NETWORKS AND UNIT FOR PROCESSING SAID INFORMATION
20200107052 · 2020-04-02 · ·

A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of receivers includes exploring streams broadcasted by a DVB network and streams broadcasted by an IP network and extracting services information from these streams, completing an information table, situated at the highest level in a hierarchy of services information tables, included in the service information DVB-SI transmitted by the DVB network by services information related to the IP network, and transmitting the completed information table in the streams broadcasted by the DVB network towards the receivers having two switchable receiving modules, connected respectively to a DVB and an IP services broadcasting network. The receivers are able to activate the reception of digital data of a service, equivalent to the service currently received, with a second receiving module when receiving conditions of a first receiving module are degraded.

RECEPTION APPARATUS, TRANSMISSION APPARATUS, AND DATA PROCESSING METHOD

The present technique relates to a reception apparatus, a transmission apparatus, and a data processing method that enable to execute a process according to delivery of resource files of an application associated with content. The reception apparatus receives content, acquires resource delivery information regarding delivery of one or a plurality of resource files that are part of an application associated with the content, the resource delivery information transmitted along with the content, and executes a process according to the delivery of the resource files on a basis of the acquired resource delivery information. The present technique can be applied to, for example, a television receiver that can receive digital broadcasting.
