摘要： Techniques to deliver targeted advertisements and multimedia contents to viewers. Various types of advertisements are encoded and transmitted. The advertisements may be targeted for different coverage areas (e.g., national and local levels) and may further include various categories (e.g., kids, sports, business, and so on). At the terminal, one or more advertisements may be selected for display based on various selection schemes. The particular advertisement to be selected for display at a terminal may be based on the terminal's assigned profile or user interaction at the terminal. The profile may be assigned based on the last program viewed at the terminal, a particular filter icon selected at the terminal, the observed television viewing habits of the viewer at the terminal, and so on. The techniques may also be advantageously used for delivery of other multimedia contents and for other applications.

摘要： Techniques to efficiently deliver interactive program guide (IPG). In one aspect, if an IPG page is requested by a viewer and not already transmitted, only the guide portion for the requested page is sent instead of the entire page. The requested page includes a guide portion that is specific to the requested page and a background portion that is common for a number of pages. The background portion can be continually broadcasted by the head-end. The requesting terminal is thus able to regenerate the requested page based on the demand-casted guide portion (i.e., transmitted upon request) and the continually broadcasted background portion. Alternatively, the entire requested page can be transmitted. In another aspect, instead of sending the requested guide portion continually, the guide portion is sent a limited number of times (e.g., only once, upon receiving the request). Since the guide portion for any particular page is normally static and does not change over time, sending the guide portion a limited number of times (e.g., once) is typically sufficient and greatly reduces bandwidth usage.

摘要： Indexing techniques to maintain track of IPG pages and allow a terminal to determine whether a selected IPG is currently received and available, which regions are to be assembled together to generate the selected page, and which packet identifiers (PIDs) are to be processed to recover the needed regions. In one method, a “roster” is formed which includes a number of record elements, with each record element being associated with and identifying a respective IPG page received at a terminal. Each record includes a page ID field that specifically identifies the associated IPG page. A number of fields may be included in each record element such as fields for a guide PID, a video PID, a data PID, and so on. The roster is updated to reflect changes in IPG pages received at the terminal.

摘要： A data structure for representing program data that includes a number of streams. Each stream comprises a group of pictures (GOP) having a first picture and remaining pictures. The data structure includes a first set of one or more elements for representing data for the first pictures in the GOPs, and a second set of one or more elements for representing data for the remaining pictures in the GOPs. At least one element in the first set represents data for the first picture of at least one respective GOP, with each such first picture having been encoded as a reference I picture. Each remaining element (if any) in the first set represents data for the first picture of a respective remaining GOP, with each such remaining first picture having been encoded as either a difference picture or a P picture. Each element in the second set represents data for a particular remaining picture in one of the GOPs, with each such remaining picture having been encoded as either a P or B picture. Each stream is represented by one or more elements in the first set and one or more elements in the second set.

摘要： An interactive program guide (IPG) may include a program grid section and a multimedia section. The program grid section typically contains program information organized in a grid with a time axis and a channel axis. The multimedia section may include video for advertisement, previews, and other purposes. Such an IPG may be rendered and encoded at a server and distributed to client terminals in the form of compressed bit streams.For certain IPGs, the program grid section may comprise alternating stripes of background with different shades (lighter/darker) or different colors. Typically, the alternating background stripes may be used to visually separate text information into timeslots or channels.Blank areas of the background may be “skip” encoded to “save” a portion of the bit rate. Meanwhile, the quantizer stepsize for encoding that section may be lowered so as to utilize the saved bits to improve the viewing quality of the program grid section. Additionally or alternatively, the quantization matrix for encoding the program grid section may be optimized for encoding text (rather than being, for example, a standard quantization matrix).Encoding may be performed on the program grid section such that encoded macroblocks do not cross a border between two stripes. In other words, each encoded macroblock in the program grid section may be within a single stripe. Additionally or alternatively, low-pass frequency filtering may be applied on the background stripes. Such low-pass filtering reduces visual defects due to ringing from edges between stripes.
