A computing system receives from a media presentation device a query fingerprint stream representing media content being presented by the media presentation device, where the query fingerprint stream has been determined to represent a first channel. The computing system then detects that a threshold mismatch exists between the received query fingerprint stream and a reference fingerprint stream representing the first channel, thus indicating a likelihood that the media presentation device has transitioned from presenting the first channel to presenting a second channel. Responsive to detecting the threshold mismatch, the system thus discontinues channel-specific action with respect to the first channel. For instance, the system could discontinue superimposing of first-channel-specific content on the presented media content and perhaps start superimposing of second-channel-specific content instead.

Structural furring systems having enhanced drainage functionality are described. Furring strips can include a substantially planar face, substantially planar webs extending from edges of the face, and substantially planar legs extending from opposite edges of the legs. The face and/or legs include a row or array of protrusions configured to accommodate drainage and ventilation between the furring strip and an attached exterior cladding and/or building substrate. Furring strips can be manufactured by rolling a sheet metal such as steel. Additional embodiments include a furring tape configured to be affixed to a substantially flat face of a commercially available furring strip to provide similar drainage features.

A composite structure for use in tiling surfaces is disclosed. The composite structure can include a fiber matrix impregnated with a water-activated setting material. The composite structure can be wet and then compressed between a tile and an application surface. The composite structure can cure to provide a support surface for the tile.

An adhesive mat for gluing a the onto a well includes a plate-side adhesive layer for connection with the tile by a material union and a wall-side adhesive layer for gluing onto the well. In this way, tiles can be handled in a clean and dry manner. The adhesive mat may already be connected to a tile at the manufacturer's end to thereby form a tile unit. The adhesive mat can have at least one overhang over the border of the tile, such that several such tile units can be arranged in a grid pattern with the adhesive mats overlapping.

A computing system compares various reference fingerprints each representing a reference media stream broadcast on a different respective known channel, and the computing system determines that a plurality of the reference fingerprints match each other, thus defining a multi-match group of the matching reference fingerprints. In response, the computing system identifies a fingerprint feature that could define a distinction between the reference fingerprints, and the computing system resolves the multi-match based on the identified feature, thereby determining the channel carrying the media stream being rendered by the media presentation device. And the server then takes channel-specific action based on the determined channel.

Disclosed is a panel comprising a substrate (1), wherein the outer surface of the substrate (1) is covered with a coating layer (8), wherein one edge of the substrate (1) is provided with a recess (3), and a groove (4) is arranged inside the substrate (1) adjacent and interconnected to the recess (4), and wherein the opposite edge of the substrate (1) is provided with a protrusion (7) that can be fitted into the recess (3), and a tongue (6) is extended from the protrusion (7) that can fitted into the groove (4). The substrate is made of 100 parts by mass of PVC resin or PVC powder, 25-45 parts of styrene elastomer, 180-280 parts of stone powder, sawdust or rock, 1-10 parts of an additive, and 1-4 parts of an elastomer coupling agent. Also disclosed is a decorative panel formed by arranging and interlocking the panels in sequence by fitting the protrusion of a panel into the recess of a neighboring panel, as well as a panel installation process.

A computing system will compare various reference fingerprints each representing a reference media stream broadcast on a different respective known channel, and the computing system will determine that a plurality of the reference fingerprints match each other, thus defining a multi-match group of the matching reference fingerprints. Further, the computing system will determine that a query fingerprint representing a media stream being rendered by a media presentation device matches the multi-match group, thus raising a question of which channel is carrying the media stream that is being rendered by the media presentation device. By considering one or more attributes of the query fingerprint, the server may then disambiguate and thereby determine the channel at issue, and the server may in turn take channel-specific action.

Disclosed are methods and systems involving location-based disambiguation of media channel identification, in a scenario where a fingerprint of media content being rendered by a media presentation device matches multiple reference fingerprints corresponding respectively with multiple different media channels. Upon detecting such a multi-match situation, a server or other entity will use a location of the media presentation device as a basis to disambiguate between the matching reference fingerprints and thus to determine the channel on which the media content being rendered by the media presentation device is arriving.
