    摘要： A method of simultaneously transmitting a video signal and encoded data representing graphic images is disclosed. The invention is particularly applicable for transmitting multilingual subtitles with a video program. The graphic images are rectangular regions within the active video area. They are transmitted in the form of bitmaps. The invention not only allows any character font or size to be displayed, but also the definition of e.g. a program provider's logo. The encoded data includes a time stamp to specify the time at which a subtitle is to be displayed. Preferred embodiments of the invention include the transmission of color-look-up-table (CLUT) data and a compatibility code indicating a required minimum number of entries of said color-look-up-table. For receivers with a CLUT having more entries than necessary, a map table is a for mapping the pixel data width to the input witdh of the relevant CLUT. The method is applicable to Direct Video Broadcast systems wherein the video signal is MPEG2 encoded and the graphic images are accommodated in a private data stream of an MPEG2 Transport Stream.

    摘要： Graphic images that overlay a transmitted video signal are provided in the form of bitmaps that allow any character or font size to be displayed. A color-look-up-table (CLUT) at a receiver is defined that maps “m” inputs to a combination of color and luminance values for display. One or more map tables are provided that allow pixel colors to be encoded using fewer than “m” bits, the map tables providing an “m” bit output for accessing the CLUT. The provider of the graphic images can also specify a required minimum number of CLUT colors for rendering the images; if this minimum is greater than “m”, the image is not rendered. The use of map tables provides compatibility between a variety of encoding techniques and a variety of rendering devices, without requiring different CLUTs to be transmitted for each different color encoding format.

    摘要： A heterogeneous layered video decoding system and associated method is disclosed that provides for flexible and cost effective scalability through the use of generic decoders (e.g., MPEG-2/4/AVC) at each layer instead of decoders specifically designed for scalable systems. In one embodiment, additional signaling information (220) embodied as a parameter list is transmitted along with the transport stream (250). The parameter list independently defines for each layer (BS, ES), how the particular layer is to be decoded. In this manner, a trade-off between complexity and efficiency is achieved. For example, the base layer (BS) may employ a sophisticated base layer AVC codec, while one or more enhancement layers (ES) may use an MPEG-2 codec that is half as complex as a full AVC codec but only slightly less efficient.

    摘要： Parallel communication sessions can be established. A system receives an email communication from a user computer, and sends a reply to the user computer, wherein the reply includes a link allowing the user computer to establish a connection to a server; and wherein the link further includes an identifier. The system then receives from the user computer a connection request based on the link, said connection request including the identifier and specifying a first phone number associated with the user computer. The system then invokes an application for establishing a first voice connection with a first terminal identified by said first phone number, establishing a second voice connection with a second terminal identified by a second phone number indicated as associated with a computer terminal, and interconnecting the first and second voice connections to establish a voice call between the first and second terminals. The system also establishes a data connection with the user computer in response to the connection request, and establishes a data connection with the computer terminal, such that the user computer and the computer terminal can share a multimedia session, such that the voice call and the multimedia session are each associated with the identifier.
