Assignee:

Coherent Logix, Incorporated - Austin TX

International Classification:

H04N 11/02

US Classification:

37524027

Abstract:

A system and method for wirelessly transmitting audiovisual information. First audiovisual information may be encoded using a first error correction coding method. A plurality of packets may be generated, including the first audiovisual information, second audiovisual information, and control information. The second audiovisual information may not be encoded using the first error correction coding method, and the control information may indicate this. The plurality of packets may be wirelessly transmitted. The control information may be usable by a receiver to determine that the second audiovisual information is not encoded using the first error correction coding method, and may thereby determine that the second audiovisual information is a different service version than the first audiovisual information.

International Classification:

G06F 13/00

US Classification:

709236, 709225, 709231

Abstract:

First control information, generated according to a first protocol version, for configuring an audiovisual device to present a multimedia stream, may be generated. A first data structure specifying that the first control information is of the first protocol version may be generated. A plurality of packets, including a multimedia stream, the first control information, and the first data structure, may be generated and transmitted. Second control information, generated according to a second protocol version, for configuring an audiovisual device to present a multimedia stream, may be generated. The first data structure may be modified to include information about the second control information. A second plurality of packets, including the modified first data structure, the first control information, a multimedia stream specified by the first control information, the second control information, and a multimedia stream specified by the second control information, may be generated.

Abstract:

A receiver system and method for recovering information from a symbol data sequence Y. The symbol data sequence Y corresponds to a symbol data sequence X that is transmitted onto the channel by a transmitter. The symbol data sequence X is generated by the transmitter based on associated information bits. At the receiver, a set of two or more processors operate in parallel on two or more overlapping subsequences of the symbol data sequence Y, where each of the two or more overlapping subsequences of the symbol data sequence Y corresponds to a respective portion of a trellis. The trellis describes redundancy in the symbol data sequence Y. The action of operating in parallel generates soft estimates for the associated information bits. The soft estimates are useable to form a receive message corresponding to the associated information bits.

International Classification:

H04N 21/266

US Classification:

725116

Abstract:

Bit efficient control information communication techniques. Control information for configuring an audiovisual device to present multimedia content may be generated. The control information may be organized according to a tree data structure having a plurality of nodes. The control information may include commands for navigating the nodes of the tree structure to locate data values stored at leaf nodes of the tree structure. Some commands may have associated data fields. Each command, and each data field, may include bit portions of uniform length. A designated bit of command bit portions may have a first value indicating that the bit portion is a command, while a designated bit of data field bit portions may have a second value indicating the bit portion is a data field. The second value may be different than the first value.

Abstract:

Control information for configuring an audiovisual device to present multimedia content according to a first service type may be generated. A method may include generating first control information for configuring an audiovisual device to decode a multimedia stream, generating first data that indicates a structure of the first control information, and transmitting the first data and the first control information. The first control information may be generated according to a first protocol version. Second data and second control information may be similarly generated and transmitted according to a second protocol version. Disclosed techniques may facilitate receiving devices to determine whether they support received wireless transmissions and decode the transmissions based on the control information.
