International Classification:

H04N007/52

US Classification:

348473, 348476

Abstract:

A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e. g. , video, audio, and optionally also other auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels of the link during data islands between bursts of encoded video data. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link.

Abstract:

A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e. g. , video, audio, and optionally also other auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels of the link during data islands between bursts of encoded video data, a pixel clock is transmitted over the link, and the receiver regenerates a clock for the audio data using time code data in the packets and the pixel clock. Other aspects of the invention are transmitters for transmitting encoded data and a pixel clock over a serial link, receivers for receiving such data and pixel clock and performing audio clock regeneration, and methods for transmitting encoded data and a pixel clock over a serial link and performing clock regeneration using the transmitted data and pixel clock.

International Classification:

US Classification:

375242, 375346, 348473, 348476

Abstract:

A system in which encoded data (e. g. , encoded video and auxiliary data) are transmitted over a serial link. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link. Source data to be transmitted are encoded using a subset of a full set of code words. The subset consists of preferred code words. Disjoint clusters of code words in the full set are predetermined. Each cluster includes one or more of the preferred words, and optionally also at least one additional code word that is similar to a preferred word of the cluster in the sense that it is likely to be generated as a result of probable bit errors in transmission, or transmission and decoding, of such preferred word. Each preferred word of a cluster is indicative of a single source data value. Each received code word in a cluster is mapped to the source data value determined by each preferred word of the cluster.

US Classification:

370503, 348473

Abstract:

A communication system including a transmitter, a receiver, and a TMDS-like link, in which video data and auxiliary data are transmitted from the transmitter to the receiver, or in which video data are transmitted over the link from the transmitter to the receiver and auxiliary data are transmitted from the receiver to the transmitter (or from the transmitter to the receiver and also from receiver to the transmitter), a transmitter or receiver for use in such a system, and methods for sending auxiliary data and video data over such a link, synchronizing such auxiliary data with such video data, and generating clocks having frequency closely matching the rate at which the auxiliary data are transmitted. Typically, the auxiliary data include one or more streams of audio data. In some embodiments the transmitter transmits a video clock to the receiver over a video clock channel, at least one of the transmitter and receiver transmits at least one stream of auxiliary data to the other one of the transmitter and the receiver, and at least one of the transmitter and the receiver transmits over the video clock channel at least one auxiliary clock for the auxiliary data.

Abstract:

A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e. g. , encoded video data and encoded auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, alternating bursts of encoded video data and encoded auxiliary data are transmitted over each of one or more channels of the link. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, and methods for sending encoded data over a serial link. In accordance with the invention, the data to be transmitted are encoded using a subset (sometimes referred to as a selected set of code words) of a full set of code words. The selected set of code words is selected such that each stream of encoded data (comprising only such code words) transmitted over a serial link has a bit pattern that is less susceptible to inter-symbol interference (“ISI”) during transmission than is the bit pattern determined by a conventionally encoded version of the same data (comprising not only the selected set of code words but also other members of the full set). In general, the best choice for the selected set of code words selected from a full set of binary code words depends on the particular coding implemented by the full set.

Assignee:

Silicon Image, Inc. - Sunnyvale CA

International Classification:

H04N 7/18

US Classification:

37524026, 37524027

Abstract:

A system including a receiver, a TMDS link (or other serial link), and a transmitter configured to transmit K-bit video words (typically, encoded 8-bit video words) over the link. In typical embodiments, the transmitter is configured to pack a sequence of N-bit video words, where N≠K (e. g. , N=10, 12, or 16, when K=8) into a sequence of K-bit fragments, encode the fragments, and transmit the encoded fragments. The transmitted data are indicative of a sequence of M-fragment groups, and the transmitter is typically configured also to transmit over the link packing phase data indicative of the phase of the most recently transmitted fragment. Other aspects are transmitters and receivers for use in such a system and methods implemented by any such transmitter, receiver, or system.

US Classification:

710 62, 710 64, 709208

Abstract:

In some embodiments, a device includes a bus, a parallel source, and a parallel sink. The parallel source is to provide parallel groups of signals including video signals to the bus, wherein the bus has a number of lanes that is fewer than a number of signals used to represent a pixel such that pixels are represented in more than one of the parallel groups. The parallel sink is to receive the parallel groups of signals from the bus, wherein the parallel sink includes a signal extractor to separate at least a portion of the groups of signals into multiple channels, and encoder and serializer circuits to encode and serialize the separated signals. Other embodiments are described and claimed.
